Recent experimental work suggests that the concept of contextual fields should be generalized to allow the modulation of local information extraction by both external and internal context. The external context relates to the coherent information of the stimulus; the internal context refers to the parts of this information which are relevant for behavior. This dual interaction, present at every level of the hierarchy, requires a fundamental unit of processing more complex than a single neuron appears today. We argue that the (...) cortical column supplies the required mechanisms for a separate top-down and bottom-up processing and allows for interaction without destructive cross-talk. This flexibility might explain why the same basic architecture of a cortical column is used in the whole isocortex. (shrink)

Peter Byrne tells the story of Hugh Everett III (1930-1982), whose "many worlds" theory of multiple universes has had a profound impact on physics and philosophy. Using Everett's unpublished papers (recently discovered in his son's basement) and dozens of interviews with his friends, colleagues, and surviving family members, Byrne paints, for the general reader, a detailed portrait of the genius who invented an astonishing way of describing our complex universe from the inside. Everett's mathematical model (called the "universal wave (...) function") treats all possible events as "equally real", and concludes that countless copies of every person and thing exist in all possible configurations spread over an infinity of universes: many worlds. Afflicted by depression and addictions, Everett strove to bring rational order to the professional realms in which he played historically significant roles. In addition to his famous interpretation of quantum mechanics, Everett wrote a classic paper in game theory; created computer algorithms that revolutionized military operations research; and performed pioneering work in artificial intelligence for top secret government projects. He wrote the original software for targeting cities in a nuclear hot war; and he was one of the first scientists to recognize the danger of nuclear winter. As a Cold Warrior, he designed logical systems that modeled "rational" human and machine behaviors, and yet he was largely oblivious to the emotional damage his irrational personal behavior inflicted upon his family, lovers, and business partners. He died young, but left behind a fascinating record of his life, including correspondence with such philosophically inclined physicists as Niels Bohr, Norbert Wiener, and John Wheeler. These remarkable letters illuminate the long and often bitter struggle to explain the paradox of measurement at the heart of quantum physics. In recent years, Everett's solution to this mysterious problem - the existence of a universe of universes - has gained considerable traction in scientific circles, not as science fiction, but as an explanation of physical reality.

Midcentury America was governed from the center, a bipartisan consensus of politicians and public opinion that supported government spending on education, the construction of a vast network of interstate highways, healthcare for senior citizens, and environmental protection. These projects were paid for by a steeply progressive tax code, with a top tax rate at one point during the Republican Eisenhower administration of 91 percent. Today, a similar agenda of government action would be portrayed as dangerously left wing. At the same (...) time, radically anti-government and anti-tax opinions are considered part of the mainstream. In _Take Back the Center_, Peter Wenz makes the case for a sane, reality-based politics that reclaims the center for progressive policies. The key, he argues, is taxing the wealthy at higher rates. The tax rate for the wealthiest Americans has declined from the mid-twentieth-century high of 91 percent to a twenty-first-century low of 36 percent--even as social programs are gutted and the gap betweeen rich and poor widens dramatically. Ever since Ronald Reagan famously declared that government was the problem and not the solution, conservatives have had an all-purpose answer to any question: smaller government and lower taxes. Wenz offers an impassioned counterargument. He explains the justice of raising the top tax rates significantly, making a case for less income inequality, and he offers suggestions for how to spend the increased tax revenues: K-12 education, tuition relief, transportation and energy infrastructure, and universal health care. Armed with Wenz's evidence-driven arguments, progressives can position themselves where they belong: in the mainstream of American politics and at the center of American political conversations, helping their country address a precipitous decline in equality and quality of life.

This is the third volume of a three-volume set on The Innate Mind. The extent to which cognitive structures, processes, and contents are innate is one of the central questions concerning the nature of the mind, with important implications for debates throughout the human sciences. By bringing together the top nativist scholars in philosophy, psychology, and allied disciplines these volumes provide a comprehensive assessment of nativist thought and a definitive reference point for future nativist inquiry. The Innate Mind: Volume 3: (...) Foundations and the Future, concerns a variety of foundational issues, as well as questions about the direction of future nativist research. It addresses such questions as: What is innateness? Is it a confused notion? What is at stake in debates between nativists and empiricists? What is the relationship between genes and innateness? How do innate structures and learned information interact to produce adult forms of cognition, e.g. about number, and how does such learning take place? What innate abilities underlie the creative aspect of language use, and of creative cognition generally? What are the innate foundations of human motivation, and of human moral cognition? In the course of their discussions, many of the contributors pose the question : Where next for nativist research? Together, these three volumes provide the most intensive and richly cross-disciplinary investigation of nativism ever undertaken. They point the way toward a synthesis of nativist work that promises to provide a powerful picture of our minds and their place in the natural order. (shrink)

We can think of the club not as a small business, but as a would‐be “anarchist‐syndicalist commune.” Anarcho‐syndicalism is a kind of anarchism based in labor unions, where workers take control of the economy not through a top‐down government bureaucracy but through revolutionary labor associations called “syndicates. The club resembles just such a syndicate: it's hierarchical, but, unlike capitalist enterprises, it is a democratically governed hierarchy. The state is essentially an instrument of class struggle and will gradually “wither away,” as (...) both the “anarchy” of capitalist markets and the centralized command economy are replaced with socialist anarchism. This chapter portrays the difference between Marxists and classical anarchists such as the French Pierre‐Joseph Proudhon and the Russian Peter Kropotkin, for whom the state should immediately be abolished. SAMCRO seems anarchistic in its principal economic relations, too, with decisions about production, distribution, and labor made by members of the MC collectively. (shrink)

The theoretical basis of criminal injuries compensation schemes is vague and, hence, the level at which awards should be set is unclear. Until recently, awards under the British Scheme were pegged at the level of common law damages but there now exists a ‘tariff’ system which sets out a standard award for each type of injury regardless of the recipient's individual losses. Up until now, it has been fairly clear that an award of compensation represents, in concrete form, an expression (...) of public sympathy with the victim. Under the new arrangements, it is probable that an award will also come to represent society's abhorrence of the offence. These two perceptions will sometimes come into conflict and the Scheme's shaky intellectual foundations mean that the tension between ‘victim-centred’ and ‘offence-centred’ approaches cannot easily be resolved. Future difficulties will be exacerbated by the fact that, in response to public criticism of the original Tariff Scheme, the new ‘hybrid’ Scheme continues to provide, in a very small number of the most serious cases, individualized ‘top-up’ payments to cover the victim's lost earnings and expenses.

In Behind Every Lesson There is a Wonderful Journey, Peter Burwash shows us how he took advantage of one the most important success keys to create an extraordinary life. The open secret that Peter reveals is that every successful person took the time to gather lessons from other successful people and imbibe those lessons. Parents, friends, teachers, employers, famous athletes, politicians, movie stars/ producers, comedians, spiritual leaders, entrepreneurs all helped the author through word and deed to transform his (...) life. Peter retraces the pivotal encounters he had with those who helped him rise from obscure beginnings in eastern Canada to become a top international tennis pro, an internationally sought after motivational speaker, the CEO of Peter Burwash Inernational (PBI), a worldwide tennis management company, and a successful author, husband, and father. In his humble and genuine style the author gives the reader a treasure house of wisdom. Some lessons are directly from his long and impressive list of mentors and some lessons are his personal realizations earned by working for decades to transform his own life both externally and internally. All are valuable gems for your taking. (shrink)

Although the UN and EU focus their climate policies on the prevention of a 2 8C global mean temperature rise, it has been estimated that a rise of at least 4 8C is more likely. Given the political climate of inaction, there is a need to instigate a bottom-up approach so as to build domestic support for future climate treaties, empower citizens, and motivate leaders to take action. A review is provided of the predominant top-down cap-and-trade policies in place – (...) the Kyoto Protocol and EU Emissions Trading Scheme (EU ETS) – with a focus on the grandfathering of emissions entitlements and the possibility of offsetting emissions. These policies are evaluated according to two criteria of justice and it is concluded that they fail to satisfy them. Some suggestions as to how the EU ETS can be improved so as to enable robust climate action are also offered. (shrink)

For leading corporations, talent is perhaps the only truly sustainable competitive advantage. In light of this, leading international corporations need to be staffed by the best possible executive talent from around the world. This talent revolution places a burden on business schools to offer highly focused learning, based on practical research. In addition, business schools face fierce competition in this sector, not least from the rapid growth in management education in India and South East Asia. Thought Leadership Meets Business offers (...) significant insights into the factors that have led to the delivery of high-quality executive education at the top-ranking International Institute for Management Development. Drawing on the experience and wisdom gained by IMD President Peter Lorange over a distinguished career of more than twenty years, this book offers a powerful model for business school success.

Emerging as a hot topic in the mid-twentieth century, causality is one of the most frequently discussed issues in contemporary philosophy. Thinking about Causes brings together top philosophers from the United States and Europe to focus on causality as a major force in philosophical and scientific thought.

History reveals how civilisations can be decimated by changes in climate. More recently modern methods of warfare have exposed the vulnerability of the artefacts of civilisation. Bringing together a range of subjects - from science, energy and sustainability to aesthetics theory and civilization theory - this book uniquely deals with climate change and the ensuing catastrophes in relation to cultural factors, urbanism and architecture. It links the evolution of civilisation, with special emphasis on the dynamics of beauty as displayed in (...) architecture and urbanism, to climate change. It then considers both the historic and predicted impacts of climate change and the threat it poses to the continued viability of human civilisation when survival is the top priority. This book gives students, researchers and professionals in architecture and sustainable design as well as anyone interested in the threat of global warming to civilisation, new insights as to what could be lost if action is not taken at a global level.

This article challenges Block's ‘overflow argument’ for the conclusion that phenomenal consciousness and access-consciousness are distinct. It shows that the data can be explained just as well in terms of a distinction between contents that are made globally accessible through bottom–up sensory stimulation and those that are sustained and made available in working memory through top-down attention.

It is unknown to what extent medical researchers generalize study findings beyond their samples when their sample size, sample diversity, or knowledge of conditions that support external validity do not warrant it. It is also unknown to what extent medical researchers describe their results with precise quantifications or unquantified generalizations, i.e., generics, that can obscure variations between individuals. We therefore systematically reviewed all prospective studies (n = 533) published in the top four highest ranking medical journals, Lancet, New England Journal (...) of Medicine (NEJM), Journal of the American Medical Association (JAMA), and the British Medical Journal (BMJ), from January 2022 to May 2023. We additionally reviewed all NEJM Journal Watch clinical research summaries (n = 143) published during the same time. Of all research articles reporting prospective studies, 52.5% included generalizations beyond specific national study populations, with the numbers of articles with generics varying significantly between journals (JAMA = 12%; Lancet = 77%) (p < 0.001, V = 0.48). There was no evidence that articles containing broader generalizations or generics were correlated with larger or more nationally diverse samples. Moreover, only 10.2% of articles with generalizations beyond specific national populations reported external validity strengthening factors that could potentially support such extrapolations. There was no evidence that original research articles and NEJM Journal Watch summaries intended for practitioners differed in their use of broad generalizations, including generics. Finally, from the journal with the highest citation impact, articles containing broader conclusions were correlated with more citations. Since there was no evidence that studies with generalizations beyond specific national study populations or with generics were associated with larger, more nationally diverse samples, or with reports of population similarity that may permit extensions of conclusions, our findings suggest that the generalizations in many articles were insufficiently supported. Caution against overly broad generalizations in medical research is warranted. (shrink)

In their own words, many of the world's foremost mathematicians discuss the art and practice of their work in this book, which shines a light on some of the issues of mathematical creativity. It is neither a philosophical treatise nor the presentation of experimental results, but a compilation of reflections from top-calibre working mathematicians. This approach highlights the creative aspects of the field, illustrates the dramatic variation by individual, and hopes to express the vibrancy of creative minds at work. Organised (...) alphabetically, this book is meant for a general audience and is best read by browsing. It can be used as a supplementary text in mathematics history and mathematics education courses. (shrink)

This article aims: (1) to introduce the wider philosophy of Aristotle to nurses and healthcare practitioners; (2) to show that Aristotle's philosophical system is an interdependent whole; and (3) to defend its plausibility and usefulness despite its ancient and alien origins.Aristotle's system can be set out as a hierarchy, with metaphysics at the top and methodology running throughout. Beneath metaphysics are the sciences, with theoretical, practical and productive (or craft) sciences in hierarchical order. This hierarchy does not imply that, say, (...) metaphysics is superior to biology or nursing, but rather that metaphysics can be understood without reference to the other two but, as we shall see, notvice versa.Two themes run through Aristotelian philosophy. The first is Aristotle's method of inquiry, central to which is that our starting point is not pure empirical data, but rather current puzzles; complementing this method is a realist philosophy. The second theme is teleology, the understanding of action in the world in terms of ends, as when we say a plant grows roots to reach water and nutrients.Implications for nursing. Good health is the good functioning of the material aspect of humans; flourishing is good functioning of humansper se. The goals of nursing, which are based on health, are subsumed by the overall human goal of flourishing, and this helps us to understand and set boundaries to health care. Two examples illustrate this. The first is that mental illness is strongly within the purview of nursing and health care whereas bad decisions, such as smoking, are only marginally so. The second is ethics, where it is argued that the attempt to describe ethical decision‐making as in addition to and separate from the decisions made within nursing and health care itself cannot be sustained.

This article considers the relationship between business ethics and philosophy, specifically in relation to the field and persons working in it. The starting point is a grammatical one: business ethics by the rules of grammar belongs to ethics. In terms of academic disciplines, it belongs to applied ethics, which belongs to ethics, which belongs to practical philosophy, which belongs to philosophy. However, in the field of business ethics today one will seldom meet colleagues from philosophy; instead, they will come from (...) business, applying business studies perspectives, approaches, and increasingly quantitative methods. This article provides empirical evidence that today the three top journals with “business ethics” in their titles are mostly run by business scholars with PhDs in business. The article compares the three journals today with their inaugural issues and finds that at their inception all three were run by a majority of philosophers. The article discusses six possible explanations for this shift and provides suggestions for how to bring business ethics back to philosophers. (shrink)

This account of the logic of rules is stratified. The various layers consist of the logic of states, i.e. essentially classical logic (of the usual sort), the logic of agents and action types (or as I call them routines), and the logic of rules proper, as the top layer. It is assumed in this essay that the reader has an adequate grasp of classical logic.

Given that cities are now bearing the brunt of migration and integration, it might seem that we should shift our normative focus away from the state towards the city. This is the suggestion of Avner de Shalit’s (2018) Cities and Integration: Political and Moral Dilemmas in the New Era of Migration. In this article, we suggest that this move is not so straightforward. Other levels, including the global, the state, and the neighbourhood, on top of the city, are also impacted (...) by migration and so also have claims for normative priority, which need to be addressed. And even if the city is responsible for integration, we argue that de Shalit’s promotion of Amsterdam’s ‘Milkshake Model’ – a form of respect and appreciation of difference – is, despite its clear initial appeal, not an ideal for accommodating diversity.

While theories of rationality and decision making typically adopt either a single-powertool perspective or a bag-of-tricks mentality, the research program of ecological rationality bridges these with a theoretically-driven account of when different heuristic decision mechanisms will work well. Here we described two ways to study how heuristics match their ecological setting: The bottom-up approach starts with psychologically plausible building blocks that are combined to create simple heuristics that fit specific environments. The top-down approach starts from the statistical problem facing the (...) organism and a set of principles, such as the bias– variance tradeoff, that can explain when and why heuristics work in uncertain environments, and then shows how effective heuristics can be built by biasing and simplifying more complex models. We conclude with challenges these approaches face in developing a psychologically realistic perspective on human rationality. (shrink)

Singer returns to the major arguments and examples of his seminal 1975 work and brings us to the current moment. This edition, revised from top to bottom, covers important reforms in the European Union, and now in various U.S. states. On the flip side, Singer shows the impact of the expansion of factory farming due to demand for animal products in China. Singer describes how meat consumption is taking a toll on the environment, and factory farms pose a profound risk (...) for spreading new viruses even worse than COVID-19. Animal Liberation Now includes alternatives to what has become a profound environmental and social as well as moral issue. Framed as an appeal to conscience, fairness, decency, and justice, it is intended for the supporter and the skeptic alike. -- Provided by publisher. (shrink)

In previous funding literature, ample attention has been devoted to the consequences of competition for project grants. These consequences tend to be fueled by status distinctions among grants, but scant attention has been directed toward how such distinctions are constructed. My aim with this paper is to develop new knowledge about the ways in which scientists ascribe meanings that construct status distinctions among grants. Employing qualitative data and a Bourdieu-inspired field perspective, I analyze how early-career scientists in Sweden attributed meanings (...) that constructed and distinguished the status of European Research Council (ERC) Starting Grants (StGs) and Swedish Research Council (SRC) Reserve Grants (RGs), which were otherwise closely connected by common evaluation procedures and equivalent monetary amounts. My findings show how scientists – despite having received equivalent monetary amounts – ascribed starkly different meanings to ERC StGs and SRC RGs, building on perceptions of minimal, yet competition-grounded and expert-sanctioned, divisions introduced by panelists among top-graded applicants during the ERC’s evaluations. These divisions were amplified when scientists recast StGs as ‘prizes’ and RGs as ‘consolations’. Such recasting was largely unaltered by acknowledgments that ERC StGs generated much more administrative burdens and economic troubles than SRC RGs. Those burdens and troubles were approached by StG and RG recipients alike as the cost of status, and they believed universities adopted a similar approach. I use my findings to propose contributions, policy implications, and future inquiry avenues suggesting evaluation procedures may play a larger role than monetary amounts for the construction of status distinctions among grants.

The creation of a specialized executive position that oversees sustainability activities represents a distinct shift in the structure of top management teams and their approach for addressing sustainability concerns. However, little is known about these management team members, namely the corporate sustainability officers or CSOs. We examine CSO appointments and their association with subsequent sustainability performance. Our results indicate that the creation of a CSO position may represent more of a symbolic versus substantive governance mechanism. Further tests suggest that CSO (...) expertise and the firm’s existing sustainability performance affect the association between the CSO and post-appointment sustainability performance. We find no association between CSO appointments and subsequent sustainability performance for firms that were already poor performers, while firms possessing relatively higher levels of prior sustainability performance appointing a CSO begin to experience significant improvements to performance after 3 years. We further find that CSOs with prior sustainability expertise are associated with increases in sustainability performance in firms that were already strong performers, but not in firms with poor sustainability performance. Non-expert CSOs, on the other hand, are associated with initial decreases in performance for poor performing firms, whereas better performing firms hiring non-expert CSOs are able to rely on other sustainability attributes of the firm and benefit from improvements in performance in the long term. We discuss the potential importance of these positions as it relates to symbolic versus substantive governance mechanisms through the lens of top management team literature streams. (shrink)

This study builds upon the top management literature to predict and test antecedents to firms’ engagement in corruption. Building on a survey of 341 executives in India, we find that if executives have social ties with government officials, their firms are more likely to engage in corruption. Further, these executives are likely to rationalize engaging in corruption as a necessity for being competitive. The results collectively illustrate the role that executives’ social ties and perceptions have in shaping illegal actions of (...) their respective firms. (shrink)

This interview – conducted by Peter Beilharz and Trevor Hogan with Clinton Walker over the course of three months (July to September 2011) between Melbourne and Sydney via email and Skype – explores the questions of Australian popular culture writing with, against, and of the culture industries themselves. Walker is a leading freelance Australian cultural historian and rock music journalist. He is the author of seven books, five about Australian music. He has been a radio DJ and TV presenter. (...) He compiled and produced four double CD album collections of Australian music – Inner City Sound, Buried Country, Long Way to the Top, and Studio 22. He has been a key writer in several multi-media projects, including the Powerhouse Museum Real Wild Child exhibition and CD-Rom (1995) and ABC TV’s hit documentary series/CD/DVD Long Way to the Top (2001). In 2006, a new US edition of his first book Inner City Sound (with soundtrack CD) was published. His Golden Miles: Sex, Speed and the Australian Muscle Car (2005) has been published in a revised edition in 2009. In 2012, his eighth book, The Wizard of Oz, will be published. Walker is currently writing with Beilharz and Hogan a book called The Vinyl Age: The History of Australian Rock Music, 1945–1995. The interviewers invited Walker to reflect critically on his 35-year ‘career’ as pop avatar, independent writer and critic in the post-war to post-modern Australian popular culture industries. Going from journalism to his path-finding books and television documentaries, the article traces this work’s development both in personal terms and as a symptom of the broader cultural evolution, from the suburbs to pop to art and rock and back again; between London and the provincial cultures of Oz; from one-way American consumerism to local DIY egalitarianism, analogue to digital to global dialogue, youth culture to multi-culturalism, and from the putative low brow to the legimitization process itself of popular culture.

We argue that pre-cueing studies show that perception is cognitively penetrated via mental imagery. It is important to be clear about the relation between attention and mental imagery here. We do not want to question the role of attention in pre-cueing studies. After all, it is attention that is being pre-cued. The pre-cue draws attention to certain features, which via top-down connections induces mental imagery for the pre-cued properties, which, then, after stimulus-presentation, interacts with and influences the online computations that (...) process stimulus features. That is, what mediates the cognitive penetration of perceptual processing is not pre-cued attention, but cue-induced mental imagery. (shrink)

A new global leadership paradigm is gradually emerging, spiritual-based leadership. The article context-ualizes this development within a framework of scientific and economic rationality. In contrast to these, a spiritual approach to leadership is presented as integrating a leader's inner perspective on the purpose of life and leadership such that this inner perspective is the foundation for decisions and actions in the outer world of business. Empirical research is presented, based on interviews with 31 top leaders from 15 countries in six (...) continents. It demonstrates that leaders can obtain happiness, respect, peace of mind and success, while at the same time serving the needs of all those affected by their leadership when they lead from a spiritual basis. It also indicates that spirituality can serve as the foundation for leadership that considers ethics, social responsibility and concern for the environment not just as instruments to protect corporate reputation and income generation but as fundamental principles and values in their own right.

Background There are numerous ethical challenges that can impact patients and families in the health care setting. This paper reports on the results of a study conducted with a panel of clinical bioethicists in Toronto, Ontario, Canada, the purpose of which was to identify the top ethical challenges facing patients and their families in health care. A modified Delphi study was conducted with twelve clinical bioethicist members of the Clinical Ethics Group of the University of Toronto Joint Centre for Bioethics. (...) The panel was asked the question, what do you think are the top ten ethical challenges that Canadians may face in health care? The panel was asked to rank the top ten ethical challenges throughout the Delphi process and consensus was reached after three rounds. Discussion The top challenge ranked by the group was disagreement between patients/families and health care professionals about treatment decisions. The second highest ranked challenge was waiting lists. The third ranked challenge was access to needed resources for the aged, chronically ill, and mentally ill. Summary Although many of the challenges listed by the panel have received significant public attention, there has been very little attention paid to the top ranked challenge. We propose several steps that can be taken to help address this key challenge. (shrink)

The paper documents the post-war retrenchment and failure of the post-war British Consumer Co-operative Movement. In contrast to the general failure one CEO, Terry Thomas stands out both for his success in co-operative rebranding and returning to profitability the UK Co-operative Bank and because he alone amongst the top echelons of the Co-operative Groups Management based his strategies on a clearly articulated philosophy based on his understanding of the values and purpose of the co-operative movement rooted in its historical traditions (...) grounded in the writings and achievements of Robert Owen, The paper goes on to provide a case study of the bank’s process of transformation from loss-making subsidiary to the first positive co-operative national brand in the post-war period of its history. The author argues that lack of appropriate vision based on the founding values and purposes of the Co-operative Movement is the principal reason for the management’s and governance failures that have beset the UK Co-operative Group. Instead of using the past to help in understanding the present and planning for the future, the UK Co-operative Group Leadership ignored it or worse used the past successes to congratulate itself and disguise its manifest failures. In this, they were supported by an uncritical Co-operative Union. Davis argues large co-operatives cannot be managed by a civil service responsible to an elected board. Co-operatives need a servant-leadership model of professional management dedicated to the transformational goals set by the founders of the co-operative movement. This needs a radical rethink and promotion of co-operative management education and a dedicated executive recruitment that seeks out value-based professionals whose attitudes and values are compatible with Co-operative values, ownership and purpose.

The mere presence of irrelevant external stimuli results in interference with the fidelity of details retrieved from long-term memory (LTM). Recent studies suggest that distractibility during LTM retrieval occurs when the focus of resource-limited, top-down mechanisms that guide the selection of relevant mnemonic details is disrupted by representations of external distractors. We review findings from four studies that reveal distractibility during episodic retrieval. The approach cued participants to recall previously studied visual details when their eyes were closed, or were open (...) and irrelevant visual information was present. The results showed a negative impact of the distractors on the fidelity of details retrieved from LTM. An fMRI experiment using the same paradigm replicated the behavioral results and found that diminished episodic memory was associated with the disruption of functional connectivity in whole-brain networks. Specifically, network connectivity supported recollection of details based on visual imagery when eyes were closed, but connectivity declined in the presence of visual distractors. Another experiment using auditory distractors found equivalent effects for auditory and visual distraction during cued recall, suggesting that the negative impact of distractibility is a domain-general phenomenon in LTM. Comparisons between older and younger adults revealed an aging-related increase in the negative impact of distractibility on retrieval of LTM. Finally, a new study that compared categorization abilities between younger and older adults suggests a cause underlying age-related decline of visual details in LTM. The sum of our findings suggests that cognitive control resources, although limited, have the capability to resolve interference from distractors during tasks of moderate effort, but these resources are overwhelmed when additional processes associated with episodic retrieval, or categorization of complex prototypes, are required.

We prove that a number of axioms, each a consequence of PFA (the Proper Forcing Axiom) are equivalent. In particular we show that TOP (the Thinning-out Principle as introduced by Baumgartner in the Handbook of set-theoretic topology), is equivalent to the following statement: If I is an ideal on ω 1 with ω 1 generators, then there exists an uncountable $X \subseteq \omega_1$ , such that either [ X] ω ∩ I = ⊘ or $\lbrack X\rbrack^\omega \subseteq I$.

The problem with authenticity—the idea of being “true to one’s self”—is that its somewhat checkered reputation garners a complete range of favorable and unfavorable reactions. In educational settings, authenticity is lauded as one of the top two traits students desire in their teachers. Yet, authenticity is criticized for its tendency towards narcissism and self-entitlement. So, is authenticity a good or a bad thing? The purpose of this article is to develop an intimate understanding of authenticity by investigating its current interpretation (...) and criticisms, its struggle with narcissism and relation to freedom. Examining authenticity as multilayered self-exploration reveals a composite of understanding, care, and acceptance. While a side current of acceptable tension shifts our understanding of authenticity from the security of self-determination to the messy interplay involved in being “true to one’s self” and being “in-the-world”.

Our ability to rapidly distinguish new from already stored information is important for behavior and decision making, but the underlying processes remain unclear. Here, we tested the hypothesis that contextual cues lead to a preselection of information and, therefore, faster recognition. Specifically, on the basis of previous modeling work, we hypothesized that recognition time depends on the amount of relevant content stored in long-term memory, i.e., set size, and we explored possible age-related changes of this relationship in older humans. In (...) our paradigm, subjects learned by heart four different word lists written in different colors. On the day of testing, a color cue indicated with a probability of 50% that a subsequent word might be from the corresponding list or from a list of new words. The old/new status of the word had to be distinguished via button press. As a main finding, we can show in a sample of n = 49 subjects, including 26 younger and 23 older humans, that response times increased linearly and logarithmically as a function of set size in both age groups. Conversely, corrected hit rates decreased as a function of set size with no statistically significant differences between both age groups. As such, our findings provide empirical evidence that contextual information can lead to a preselection of relevant information stored in long-term memory to promote efficient recognition, possibly by cyclical top-down and bottom-up processing.

Needless to say, Charles Parsons’s long awaited book1 is a must-read for anyone with an interest in the philosophy of mathematics. But as Parsons himself says, this has been a very long time in the writing. Its chapters extensively “draw on”, “incorporate material from”, “overlap considerably with”, or “are expanded versions of” papers published over the last twenty-five or so years. What we are reading is thus a multi-layered text with different passages added at different times. And this makes for (...) a rather bumpy read. There is another route Parsons could have taken: he could have reprinted the relevant papers with postscripts, and then top-and-tailed the collection with a preface and added concluding reflections. It must sound very ungrateful, but I rather suspect that that might have worked better. Much of the book is about arithmetic. But Parsons has woven into the discussion claims about mathematics more generally and about set theory in particular. We might well have a basic worry about this structure: for do defensible claims about the ontology and epistemology of arithmetic have to be generalizable to apply to more infinitary mathematics? For example, suppose you are attracted to a Hellman-like modal structuralist account of arithmetic: then should you think it a problem if you suspect that such an account can’t readily be extended to cope e.g. with set theory (since you boggle at the idea of possible worlds free of abstracta but with enough structure to somehow model ZFC)? Parsons himself seems to waver over such questions. So for present purposes, I’ll focus just on arithmetic, and in what follows I’ll revisit two of the most familiar Parsonian themes, his views on structuralism as an account of the ontology of arithmetic, and his exploration of the role of intuition in grounding arithmetical knowledge.

Howard's (2005) claim that male dominance in chess is 'consistent with the evolutionary psychology view that males predominate at high achievement levels at least partly because of ability differences' (p. 378) is based on the premise that top level chess skill depends on a high level of IQ and visuospatial abilities. This premise is not supported by empirical evidence. In 1927 Djakow et al. first showed that world-class chess players do not have exceptional intellectual abilities. This finding has subsequently been (...) confirmed many times. Different participation rates, or differences in the amount of practice, motivation and interest for chess in male and female chess players, may provide a better explanation for gender differences in chess performance.

We deal with the ranking problem of the nodes in a directed graph. The bilateral relationships specified by a directed graph may reflect the outcomes of a sport competition, the mutual reference structure between websites, or a group preference structure over alternatives. We introduce a class of scoring methods for directed graphs, indexed by a single nonnegative parameter α. This parameter reflects the internal slackening of a node within an underlying iterative process. The class of so-called internal slackening scoring methods, (...) denoted by λα, consists of the limits of these processes. It is seen that λ0 extends the invariant scoring method, while λ∞ extends the fair bets scoring method. Method λ1 corresponds with the existing λ-scoring method of Borm et al. (Ann Oper Res 109(1):61–75, 2002) and can be seen as a compromise between λ0 and λ∞. In particular, an explicit proportionality relation between λα and λ1 is derived. Moreover, the internal slackening scoring methods are applied to the setting of social choice situations where they give rise to a class of social choice correspondences that refine both the Top cycle correspondence and the Uncovered set correspondence.

We clarify the arguments in Neural organization: Structure, function, and dynamics, acknowledge important contributions cited by our critics, and respond to their criticisms by charting directions for further development of our integrated approach to theoretical and empirical studies of neural organization. We first discuss functional organization in general (behavior versus cognitive functioning, the need to study body and brain together, function in ontogeny and phylogeny) and then focus on schema theory (noting that schema theory is not just a top-down theory (...) and discussing the transition from action-oriented perception to cognition). We then turn to dynamical organization, with a focus first on neural modeling and dynamics (clarifying the multiple functions of neurons and brain regions, and looking further at various forms of dynamics) and second on learning, development, and self-organization (looking at monoaminergic systems, reinforcement, self-organization, postnatal development, and disease). We close with a brief philosophical discussion of postmodernism and reductionism. (shrink)

In the French presidential election, both candidates tried to keep their domestic life separate from their campaign. Ségolène Royal is not married to François Hollande, the father of her four children. When asked whether they were a couple, Royal replied, “Our lives belong to us.” Similarly, in response to rumors that President-elect Nicholas Sarkozy’s wife had left him, a spokesman for Sarkozy said, “That’s a private matter.” The French have a long tradition of respecting the privacy of their politicians’ personal (...) lives, and French public opinion is more broad-minded than in the United States, where an unwed mother of four would have no chance of being nominated for the presidency by a major party. Indeed, last month, Randall Tobias, the top foreign aid adviser in the US State Department, resigned after acknowledging that he had used an escort service described as providing “high-end erotic fantasy” – although Tobias said he only had a massage.

Problems arising from the transformation of Hungary from a monolithic society into a market economy are addressed. In the past, under communism, the worker was a faceless digit in a mass proletariat. He had no rights, but also no sense of obligation to society and the community. How can the business community instil in its worker a sense of their own unique individuality and role in their company and in society, a psychological awakening that will benefit not only the works (...) himself but his employer and the company's end product? This new corporate culture must trickle down from the management who must undertake the task of re?educating their workers in the interests of improved production and a better society. The author calls this the Molecule Maxim, in that management must stop thinking from the top downwards and start at the bottom of the pyramid, radiating outwards and upwards from this infinitesimal particle?the molecule?around which to build the concept, aim the creativity and thus the ultimate success and profitability of the company.

Despite the compelling subjective experience of executive self-control, we argue that ‘consciousness’ contains no top-down control processes. We propose that ‘consciousness’ involves no executive, causal or controlling relationship with any of the familiar psychological processes conventionally attributed to it. In our view all psychological processing and psychological products are non-conscious. In particular, we argue that all ‘contents of consciousness’ are generated by and within non-conscious brain systems in the form of a continuous self-referential personal narrative that is not directed or (...) influenced in any way by the ‘experience of consciousness’. This continuously updated personal narrative arises from selective ‘internal broadcasting’ of outputs from non-conscious executive systems that have access to all forms of cognitive processing, sensory information and motor control. The personal narrative provides information for storage in autobiographical memory and is underpinned by constructs of self and agency, also created in non-conscious systems. The experience of consciousness, is seen as a passive accompaniment to the non-conscious processes of internal broadcasting and the creation of the personal narrative. In this sense personal awareness is analogous to the rainbow which accompanies physical processes in the atmosphere but exerts no influence over them. Though at an individual level it is an end-product created by non-conscious executive systems, the personal narrative serves the powerful evolutionary function of enabling individuals to communicate (externally broadcast) the contents of internal broadcasting. This in turn allows the recipients to generate potentially adaptive strategies, such as predicting the behavior of others and underlies the development of social and cultural structures, that promote species survival. Consequently, it is the capacity to communicate to others the contents of the personal narrative that confers an evolutionary advantage – not the experience of consciousness (personal awareness) itself.

Many have argued that early visual processing is encapsulated from the influence of higher-level goals, expectations, and knowledge of the world. Here we confront the main arguments offered in support of such a view, showing that they are unpersuasive. We also present evidence of top–down influences on early vision, emphasizing data from cognitive neuroscience. Our conclusion is that encapsulation is not a defining feature of visual processing. But we take this conclusion to be quite modest in scope, readily incorporated into (...) mainstream vision science. (shrink)

Codes of ethics are directly aimed at behavioral control, but they also affect a company’s ethical culture, which in turn concerns compliance and ethical behavior. To positively influence a company’s ethical culture, employees must be familiar with its code of ethics, perceive that top management is committed to the code, and believe that their peers also comply with the code. The evidence on whether a code’s design affects a company’s ethical culture is limited. This study’s factorial survey experiment contributes to (...) this gap in two ways: first, it investigates whether a code’s design affects how easily the code can be learned and, therefore, contributes to code familiarity. Second, it examines how a code can convey expectations regarding top management’s commitment and peers’ behavior, both of which are part of ethical culture. The results indicate that a positive tone increases code familiarity, and a code signed by top managers sends a strong signal of their commitment to the code. Finally, various implications of the results for research and practice are discussed. (shrink)

PURPOSE—A substantial fraction of the observations made by clinicians and entered into patient records are expressed by means of negation or by using terms which contain negative qualifiers (as in “absence of pulse” or “surgical procedure not performed”). This seems at first sight to present problems for ontologies, terminologies and data repositories that adhere to a realist view and thus reject any reference to putative non-existing entities. Basic Formal Ontology (BFO) and Referent Tracking (RT) are examples of such paradigms. The (...) purpose of the research here described was to test a proposal to capture negative findings in electronic health record systems based on BFO and RT. METHODS—We analysed a series of negative findings encountered in 748 sentences taken from 41 patient charts. We classified the phenomena described in terms of the various top-level categories and relations defined in BFO, taking into account the role of negation in the corresponding descriptions. We also studied terms from SNOMED-CT containing one or other form of negation. We then explored ways to represent the described phenomena by means of the types of representational units available to realist ontologies such as BFO. RESULTS—We introduced a new family of ‘lacks’ relations into the OBO Relation Ontology. The relation lacks_part, for example, defined in terms of the positive relation part_of, holds between a particular p and a universal U when p has no instance of U as part. Since p and U both exist, assertions involving ‘lacks_part’ and its cognates meet the requirements of positivity. CONCLUSION—By expanding the OBO Relation Ontology, we were able to accommodate nearly all occurrences of negative findings in the sample studied. (shrink)
