The realities and myths of long-term care and the challenges it poses for the ethics of autonomy are analyzed in this perceptive work. The book defends the concept of autonomy, but argues that the standard view of autonomy as non-interference and independence has only a limited applicability for long term care. The treatment of actual autonomy stresses the developmental and social nature of human persons and the priority of identification over autonomous choice. The work balances analysis of the (...) ethical concepts associated with autonomy with discussion of the implications of the ethical analysis for long term care. A central chapter involves a phenomenological analysis of four general features of everyday experience (space, time, communication, and affectivity) and explores their practical implications for long term care. This work concludes with a discussion of the advantages associated with a phenomenologically-inspired treatment of actual autonomy for the ethics of long-term care. (shrink)
Subjects classified visible 2-digit numbers as larger or smaller than 55. Target numbers were preceded by masked 2-digit primes that were either congruent (same relation to 55) or incongruent. Experiments 1 and 2 showed prime congruency effects for stimuli never included in the set of classified visible targets, indicating subliminal priming based on long-term semantic memory. Experiments 2 and 3 went further to demonstrate paradoxical unconscious priming effects resulting from task context. For example, after repeated practice classifying 73 as (...) larger than 55, the novel masked prime 37 paradoxically facilitated the “larger” response. In these experiments task context could induce subjects to unconsciously process only the leftmost masked prime digit, only the rightmost digit, or both independently. Across 3 experiments, subliminal priming was governed by both task context and long-term semantic memory. (shrink)
Naturalists who conceive of knowledge as a natural kind are led to treat ‘knowledge’ as a natural kind term. ‘Knowledge,’ then, must behave semantically in the ways that seem to support a direct reference theory for other natural kind terms. A direct reference theory for ‘knowledge,’ however, appears to leave open too many possibilities about the identity of knowledge. Intuitively, states of belief count as knowledge only if they meet epistemic criteria, not merely if they bear a causal/historical relation (...) to the term. I will develop this objection and show that it is grounded in modal considerations central to Kripke’s work on reference. I will also argue that a more plausible externalist semantics for natural kind terms disarms the objection. (shrink)
Let ${\mathbb{BRL}}$ denote the variety of commutative integral bounded residuated lattices (bounded residuated lattices for short). A Boolean retraction term for a subvariety ${\mathbb{V}}$ of ${\mathbb{BRL}}$ is a unary term t in the language of bounded residuated lattices such that for every ${{\bf A} \in \mathbb{V}, t^{A}}$ , the interpretation of the term on A, defines a retraction from A onto its Boolean skeleton B(A). It is shown that Boolean retraction terms are equationally definable, in the sense (...) that there is a variety ${\mathbb{V}_{t} \subsetneq \mathbb{BRL}}$ such that a variety ${\mathbb{V} \subsetneq \mathbb{BRL}}$ admits the unary term t as a Boolean retraction term if and only if ${\mathbb{V} \subseteq \mathbb{V}_{t}}$ . Moreover, the equation s(x) = t(x) holds in ${\mathbb{V}_{s} \cap \mathbb{V}_{t}}$ . The radical of ${{\bf A} \in \mathbb{BRL}}$ , with the structure of an unbounded residuated lattice with the operations inherited from A expanded with a unary operation corresponding to double negation and a a binary operation defined in terms of the monoid product and the negation, is called the radical algebra of A. To each involutive variety ${\mathbb{V} \subseteq \mathbb{V}_{t}}$ is associated a variety ${\mathbb{V}^{r}}$ formed by the isomorphic copies of the radical algebras of the directly indecomposable algebras in ${\mathbb{V}}$ . Each free algebra in such ${\mathbb{V}}$ is representable as a weak Boolean product of directly indecomposable algebras over the Stone space of the free Boolean algebra with the same number of free generators, and the radical algebra of each directly indecomposable factor is a free algebra in the associated variety ${\mathbb{V}^{r}}$ , also with the same number of free generators.A hierarchy of subvarieties of ${\mathbb{BRL}}$ admitting Boolean retraction terms is exhibited.

Miller (1956) summarized evidence that people can remember about seven chunks in short-term memory (STM) tasks. However, that number was meant more as a rough estimate and a rhetorical device than as a real capacity limit. Others have since suggested that there is a more precise capacity limit, but that it is only three to five chunks. The present target article brings together a wide variety of data on capacity limits suggesting that the smaller capacity limit is real. Capacity (...) limits will be useful in analyses of information processing only if the boundary conditions for observing them can be carefully described. Four basic conditions in which chunks can be identified and capacity limits can accordingly be observed are: (1) when information overload limits chunks to individual stimulus items, (2) when other steps are taken specifically to block the recoding of stimulus items into larger chunks, (3) in performance discontinuities caused by the capacity limit, and (4) in various indirect effects of the capacity limit. Under these conditions, rehearsal and long-term memory cannot be used to combine stimulus items into chunks of an unknown size; nor can storage mechanisms that are not capacity-limited, such as sensory memory, allow the capacity-limited storage mechanism to be refilled during recall. A single, central capacity limit averaging about four chunks is implicated along with other, noncapacity-limited sources. The pure STM capacity limit expressed in chunks is distinguished from compound STM limits obtained when the number of separately held chunks is unclear. Reasons why pure capacity estimates fall within a narrow range are discussed and a capacity limit for the focus of attention is proposed. Key Words: attention; enumeration; information chunks; memory capacity; processing capacity; processing channels; serial recall; short-term memory; storage capacity; verbal recall; working memory capacity.

This paper sets forth a new theory of quantifiers and term connectives, called shadow theory , which should help simplify various semantic theories of natural language by greatly reducing the need of Montagovian proper names, type-shifting, and λ-conversion. According to shadow theory, conjunctive, disjunctive, and negative noun phrases such as John and Mary , John or Mary , and not both John and Mary , as well as determiner phrases such as every man , some woman , and the (...) boys , are all of semantic type e and denote individual-like objects, called shadows — conjunctive , disjunctive , or negative shadows, such as John-and-Mary, John-or-Mary, and not-(John-and-Mary). There is no essential difference between quantification and denotation: quantification is nothing but denotation of shadows. Individuals and shadows constitute a Boolean structure. Formal language LSD (Language for Shadows with Distributivity), which takes compound terms to denote shadows, is investigated. Expansions and enrichments of LSD are also considered toward the end of the paper. (shrink)
This paper discusses the question whether it is possible to explain the notion of a singular term without invoking the notion of an object or other ontological notions. The framework here is that of Michael Dummett's discussion in Frege: Philosophy of Language. I offer an emended version of Dummett's conditions, accepting but modifying some suggestions made by Bob Hale, and defend the emended conditions against some objections due to Crispin Wright. This paper dates from about 1989. It originally formed (...) part of a very early draft of what became my Ph.D. dissertation. I rediscovered it and began scanning it, when I had nothing better to do, in Fall 2001, making some minor editing changes along the way. Suffice it to say that it no longer represents my current views. I hope, however, that it remains of some small interest. (shrink)
Temporal externalism (TE) is the thesis (defended by Jackman (1999)) that the contents of some of an individual’s thoughts and utterances at time t may be determined by linguistic developments subsequent to t. TE has received little discussion so far, Brown 2000 and Stoneham 2002 being exceptions. I defend TE by arguing that it solves several related problems concerning the extension of natural kind terms in scientifically ignorant communities. Gary Ebbs (2000) argues that no theory can reconcile our ordinary, practical (...) judgments of sameness of extension over time with the claim that linguistic usage determines word extensions. I argue that Ebbs shows at most that no theory other than TE can effect this reconciliation. Furthermore, while Ebbs’ argument undermines Jessica Brown’s solutions to two closely related problems about natural kind term extensions (Brown 1998), TE can solve both problems without difficulty. Some criticisms of TE are briefly addressed as well. (shrink)
In this paper, I argue that the causal and description theories of natural kind term reference involve certain psychological elements. My main goal is to refine these theories with the help of empirical psychology of concepts, and to argue that the refinement process ultimately leads to the dissolution of boundaries between the two kinds of theories. However, neither the refined theories nor any other existing theories provide an adequate answer to the question of what makes natural kind terms rigid. (...) To provide an answer to this question I conclude my paper by introducing a framework of a unified theory of natural kind term reference that is built on the empirical psychology of concepts. (shrink)
Across the world, socio-economic forces are shifting the locus of long-term care from the family to institutional settings, producing significant moral, not just financial costs. This essay explores these costs and the distortions in the role of the family they involve. These reflections offer grounds for critically questioning the extent to which moral concerns regarding long-term care in Hong Kong and in mainland China are the same as those voiced in the United States, although family resemblances surely exist. (...) Chinese moral values such as virtue and filial piety embedded in a Confucian moral and social context cannot be recast without distortion in terms of modern Western European notions. The essay concludes that the Confucian resources must be taken seriously in order to develop an authentic Chinese bioethics of long-term care and a defensible approach to long-term care policy for contemporary society in general and Chinese society in particular.

This article presents Mencius' concept of human dignity in the Chinese Confucian moral tradition, focused on the context of long-term care. The double nature of Mencius' notion of human dignity as an intrinsic quality of human beings qua being human is analyzed and contrasted with the dominant Western account of human dignity as grounded in personhood. Drawing on the heuristic force of an interview with an elder person in Hong Kong, the insights of the Mencian theory of human dignity (...) are used to provide a moral foundation for long-term care for elder persons in a context of diminishing personhood and shrinking autonomy.

David Lewis's best-system analysis of laws of nature is perhaps the best known sophisticated regularity theory of laws. Its strengths are widely recognized, even by some of its ablest critics. Yet it suffers from what appears to be a glaring weakness: It seems to grant an arbitrary privilege to the standards of our own scientific culture. I argue that by reformulating, or reinterpreting, Lewis's exposition of the best-system analysis, we arrive at a view that is free of this weakness. The (...) resulting theory of laws has the surprising consequence that the term "law of nature" is indexical. (shrink)
This paper consists in a critical review of Peter Goldie's book, The Emotion. A Philosophical Exploration (Oxford: Oxford University Press, 2000). Goldie is right to distinguish between long-term emotions and emotional experiences. And he is also right to reject the view that emotions are reducible to 'feelingless' states plus some extra feelings. However, Goldie's own account in terms of "feeling towards" is problematic. Goldie would have been better advised to claim that emotional experiences are necessarily emotional representations of something (...) as being F (disgusting, attractive, admirable, etc.), that is, that emotional experiences are apprehensions or representations of evaluative features.

Single-unit data from the cortex of monkeys performing working-memory tasks support the main point of the target article. Those data, however, also indicate that the activation of long-term memory is essential to the processing of all cognitive functions. The activation of cortical long-term memory networks is a key neural mechanism in attention (working memory is a form thereof), perception, memory acquisition and retrieval, intelligence, and language.
. This paper examines the association between long-term compensation and corporate social responsibility (CSR) for 90 publicly traded Canadian firms. Social responsibility is considered to include concerns for social factors and the environment (e.g. Johnson, R. and D. Greening: 1999, Academy of Management Journal 42(5), 564-578; Kane, E. J. (2002, Journal of Banking and Finance 26:, 1919-1933; McGuire, J. et al. 2003, Journal of Business Ethics 45 (4), 341-359). Long-term compensation attempts to focus executives efforts on optimizing (...) the longer term, which should direct their attention to factors traditionally associated with socially responsible executives (Mahapatra, S. 1984, Journal of Financial Economicsit 20, 347-376). As hypothesized, we found a significant relationship between the long-term compensation and total CSR weakness as well as the product/environmental weakness dimension of CSR. In addition, we found a marginally significant relationship between long-term compensation and total corporate responsibility. Our findings are that executives long-term compensation is associated with a firms environmental actions, and that firms that utilize long-term compensation are more likely to mitigate product/environment weaknesses than those that do not. Implications for practice and research are discussed. (shrink)
In 1979, Lewontin and I borrowed the archi- tectural term “spandrel” (using the pendentives of San Marco in Venice as an example) to designate the class of forms and spaces that arise as necessary byproducts of another decision in design, and not as adaptations for direct utility in them- selves. This proposal has generated a large literature featur- ing two critiques: (i) the terminological claim that the span- drels of San Marco are not true spandrels at all and (ii) (...) the conceptual claim that they are adaptations and not byprod- ucts. The features of the San Marco pendentives that we explicitly defined as spandrel-properties—their necessary number (four) and shape (roughly triangular)—are inevitable architectural byproducts, whatever the structural attributes of the pendentives themselves. The term spandrel may be extended from its particular architectural use for two- dimensional byproducts to the generality of “spaces left over,” a definition that properly includes the San Marco pendentives. Evolutionary biology needs such an explicit term for features arising as byproducts, rather than adaptations, whatever their subsequent exaptive utility. The concept of biological span- drels—including the examples here given of masculinized genitalia in female hyenas, exaptive use of an umbilicus as a brooding chamber by snails, the shoulder hump of the giant Irish deer, and several key features of human mentality— anchors the critique of overreliance upon adaptive scenarios in evolutionary explanation. Causes of historical origin must always be separated from current utilities; their conf lation has seriously hampered the evolutionary analysis of form in the history of life. (shrink)
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.
Motivated by a question of W. Rautenberg, we prove that any matrix that is term-equivalent to the well-known nonfinitely based matrix of A. Wroski is itself also nonfinitely based.
This article reveals the outcome of a study on the perceptions of elders, family members, and healthcare professionals and administration providing care in a range of different long-term care facilities in Hong Kong with primary focus on the concepts of autonomy and dignity of elders, quality and location of care, decision making, and financing of long term care. It was found that aging in place and family care were considered the best approaches to long term care insofar (...) as procuring and balancing the values of dignity, autonomy, family integrity and social sustainability were concerned. An elder having the final say was generally accepted. The results also initiated the importance of sharing of financial responsibility among elders, children and government albeit the emphasis was placed on individuals. Furthermore, dignity of elders was not considered purely a synonym of autonomy, but it had also to do with respect, family and social connections. (shrink)
Long-term care is controversial because it involves foundational disputes. Some are moral-economic, bearing on whether the individual, the family, or the state is primarily responsible for long-term care, as well as on how one can establish a morally and financially sustainable long-term-care policy, given the moral hazard of people over-using entitlements once established, the political hazard of media democracies promising unfundable entitlements, the demographic hazard of relatively fewer workers to support those in need of long-term care, (...) the moral hazard to responsibility of shifting accountability to third parties, and the bureaucratic hazard of moving from individual and family choice to bureaucratic oversight. These disputes are compounded by controversies regarding the nature of the family (Is it to be regarded primarily as a socio-biological category, a fundamental ontological category of social reality, or a construct resulting from the consent of the participants?), as well as its legal and moral autonomy and authority over its members. As the disputes show, there is no common understanding of respect and human dignity that will easily lead out of these disputes. The reflections on long-term care in this issue underscore the plurality of moralities defining bioethics. (shrink)
This article documents the results of a study on the perceptions of long-term elder care in Beijing in the People's Republic of China by those most intimately involved. The study asked a sample of elderly, family members, and health care professionals, all of whom are involved in care at a variety of long-term care facilities in Beijing, about their perceptions of the care given at these facilities from their particular standpoints as regards issues such as the quality and (...) ideal location of care, decision-making regarding the care receiving, who should be responsible for the financing of care, and the meaning of dignity for the elderly in these facilities. The results showed adherence to traditional family values at least on one level regarding the ideal location of care being with the family and in the home, but also the desire to pass on financing of long-term care facilities and the health care they provide the elderly on to the government. These results are not altogether surprising, but they also clearly demonstrate the larger conflict between traditional views about morality and economic considerations regarding health care financing in the China.

The term 'culture' has more than one meaning in different contexts. The paper attempts to show certain consequences, resulting from the ambiguous use of the term 'culture', for the protection of human rights, by comparing the use of the term in the Declaration of the Principles of International Cultural Cooperation (UNESCO 1966), with its use in the Universal Declaration of Human Rights and the International Covenant on Economic, Social and Cultural Rights.

One of the most significant developments in the latter part of the 20th century and the first part of this new millennium has been the triumph of short-term over long-term thinking. We are increasingly a culture that looks neither to the past nor to the future, but only to the next “quarter,” or to the next Delphic pronouncement by Alan Greenspan. This cultural construction of time has given rise to social, political and personal problems of unprecedented magnitude. The (...) short-term focus of contemporary American capitalism is causing us to behave, both individually and collectively, in an increasingly irrational and thus self-destructive manner. Ours is now the most violent, crime-ridden society in the industrialized world. Capitalism is sometimes blamed for this, yet there are other capitalist societies that do not suffer the same evils we suffer. I argue that we can learn from these societies how to correct some of the ills of our own system and in this way construct a new paradigm of the market, a paradigm for the new millennium, a more mature, rational version of capitalism that would focus on the long rather than the short term.

Ruchkin et al. ascribe a pivotal role to long-term memory representations and binding within working memory. Here we focus on the interaction of working memory and long-term memory in supporting on-line representations of experience available to guide on-going processing, and we distinguish the role of frontal-lobe systems from what the hippocampus contributes to relational long-term memory binding.
From the start, John Dewey's ideas about education have been prone to misunderstanding. One of the greatest casualties has been "experience," a term so routinely misappropriated that Dewey ultimately decided to abandon it. He wrote, "I would abandon the term 'experience' because of my growing realization that the historical obstacles which prevented understanding of my use of 'experience' are, for all practical purposes, insurmountable. I would substitute the term 'culture' because with its meanings as now firmly established (...) it can fully and freely carry my philosophy of experience" (1981, p. 361). Dewey evidently recognized that a main challenge to understanding experience was the conceptual weight the term had .. (shrink)
The structuralist program has developed a useful metascientific resource: ontological reductive links (ORLs) between the constituents of the potential models of reduced and reducing theories. This resource was developed initially to overcome an objection to structuralist ``global'' accounts of the intertheoretic reduction relation. But it also illuminates the way that concepts at a higher level of scientific investigation (e.g., cognitive psychology) become ``structured through reduction'' to lower-level investigations (e.g., cellular/molecular neuroscience). After (briefly) explaining this structuralist background, I demonstrate how this (...) resource illuminates an actual, emerging scientific example: the link between the psychological concept of a ``consolidation switch'' from short-term to long-term memory and the cellular/molecular mechanisms of the transition from early- to late-phases of long-term potentiation (LTP) (an important type of synaptic plasticity in mammalian hippocampus and cortex).

The main powerful method for establishing termination of term rewriting systems was discovered by Nachum Dershowitz through the introduction of certain natural well founded orderings (lexicographic path orderings). This leads to natural decision problems which may be of the highest computational complexity of any decidable problems appearing in a natural established computer science context.
Neural models have proposed how short-term memory (STM) storage in working memory and long-term memory (LTM) storage and recall are linked and interact, but are realized by different mechanisms that obey different laws. The authors' data can be understood in the light of these models, which suggest that the authors may have gone too far in obscuring the differences between these processes.
It has become common in medical ethics to discuss difficult cases in terms of the principles of respect for autonomy, beneficence, nonmaleficence, and justice. These moral concepts or principles serve as maxims that are suggestive of appropriate clinical behavior. Because this language evolved primarily in the acute care setting, I consider whether it is in need of supplementation in order to be useful in the long-term care setting. Through analysis of two typical cases involving residents of long-term care (...) facilities, I argue for the additional principles of candor and responsibility for narrative integrity. (shrink)
The starting point of the investigation is the correspondence between the term and concept of Ego ("I") and the various types of experience. Two main ways of introducing and applying of the term "I" (Ego) in Russian philosophy are investigated from the semantic-analytical point of view. The first takes the Ego as initially existed either as a spiritual substance or a given form uniting experiences. This way of treating is realized in L. Lopatin's and V. Soloviev's philosophical teachings. (...) The second containing some moments of reflexion on the concept treated the Ego as a result of experience. It was developed in M. Karinskij und G. Spet. In context of difference between the Ego and the subject or consciousness the question of the owner of consciousness is considered. (shrink)
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)
Some materialists argue that we can eliminate mental entities such as sensations because, like electrons, they are theoretical entities postulated as parts of scientific explanations, but, unlike electrons, they are unnecessary for such explanations. As Quine says, any explanatory role of mental entities can be played by "correlative physiological states and events instead." But sensations are not postulated theoretical entities. This is shown by proposing definitions of the related terms, 'observation term,' and 'theoretical term,' and then classifying the (...)term 'sensation.' The result is that although 'sensation' is a theoretical term, it is also a reporting term because it is used to refer to phenomena we are aware of. Consequently sensations are not postulated and cannot be eliminated merely because they are unnecessary for explanation. (shrink)
The German term Nietzsche translators usually render in English as 'transvaluation' or 'revaluation' is 'Umwerthung.'1 The motif of revaluation can be traced back in Nietzsche's work to the period 1880-81, as Thomas Brobjer shows elsewhere in this volume, but the term 'Umwerthung' is first used only in a Nachlass note from summer-autumn 1884. Here, typically, Nietzsche is trying out a new title for his next work (his first post-Zarathustra), and we read: "Philosophie der ewigen Wiederkunft. Ein Versuch der (...) Umwerthung aller Werthe" (Philosophy of the Eternal Return: An Attempt at the Revaluation of All Values [KSA 11, p. 218]). In Nietzsche's published writings the term duly makes its appearance in that next work .. (shrink)
Cowan assumes that chunk-based capacity limits are synonymous with the essence of a “specialized STM mechanism.” In a single experiment, we measured the capacity, or span, of long-term memory and found that it, too, corresponds roughly to the magical number 4. The results imply that a chunk-based capacity limit is not a signature characteristic of remembering over the short-term.
The general theory of variable binding term operators is an interesting recent development in logic. It opens up a rich class of semantic and model-theoretic problems. In this paper we survey the recent literature on the topic, and offer some remarks on its significances and on its connections with other branches of mathematical logic.
. Recent years have witnessed the proliferation of “Christian” companies in the U.S. These firms declare their belief in, and active pursuit of, the successful merging of biblical principles with business activities. Economic success, hard work, and biblical values are seen as capable of existing together in harmony. While the number of such businesses appears to be growing, there has been a dearth of any scientific study of these companies. No empirical research has been conducted to determine whether these religious (...) values and behaviors have any significant impact on a company’s performance. The present study is designed to partially fill this gap. Specifically, it seeks to determine whether there are differences in long-term performance between self-proclaimed “Christian-based” businesses and their secular counterparts. Data were collected from 312 companies. A multivariate analysis of variance (MANOVA), followed by univariate ANOVAs, found significant differences between these two groups of firms on three of the four performance variables that were analyzed. Some explanations as well as limited generalizations and implications are developed. (shrink)
Episodic memory often is conceptualized as a uniquely human system of long-term memory that makes available knowledge accompanied by the temporal and spatial context in which that knowledge was acquired. Retrieval from episodic memory entails a form of first–person subjectivity called autonoetic consciousness that provides a sense that a recollection was something that took place in the experiencer’s personal past. In this paper I expand on this definition of episodic memory. Specifically, I suggest that (a) the core features assumed (...) unique to episodic memory are shared by semantic memory, (b) episodic memory cannot be fully understood unless one appreciates that episodic recollection requires the coordinated function of a number of distinct, yet interacting, “enabling” systems. Although these systems – ownership, self, subjective temporality, and agency – are not traditionally viewed as memorial in nature, each is necessary for episodic recollection and jointly they may be sufficient, and (c) the type of subjective awareness provided by episodic recollection (autonoetic) is relational rather than intrinsic – i.e., it can be lost in certain patient populations, thus rendering episodic memory content indistinguishable from the content of semantic long-term memory.

Using explicit memory measures, Cowan predicts a new circumstance in which the central capacity limit of 4 chunks should obtain. Supporting results for such an experiment, using continuous old-new recognition, are described. With implicit memory measures, Cowan assumes that short-term repetition priming reflects the central capacity limit. I argue that this phenomenon instead reflects limits within individual perceptual processing modules.
Optimal protective responses to long-term risks depend on rational perceptions of ambiguous risks and uncertain time horizons. Our study examined the joint influence of uncertain delay and risk in an original sample of business owners and managers. We found that many subjects disliked uncertainty in the timing of an outcome, a reaction we term ``lottery timing risk aversion.'' Such aversion to uncertain timing was positively related to aversion to ambiguous probabilities for lotteries involving storm damage risks. This association (...) suggests that uncertainty may be processed similarly in both the risk and time dimensions. (shrink)
Subjects classified visible 2-digit numbers as larger or smaller than 55. Target numbers were preceded by masked 2-digit primes that were either congruent (same relation to 55) or incongruent. Experiments 1 and 2 showed prime congruency effects for stimuli never included in the set of classified visible targets, indicating subliminal priming based on long-term semantic memory. Experiments 2 and 3 went further to demonstrate paradoxical unconscious priming effects resulting from task context. For example, after repeated practice classifying 73 as (...) larger than 55, the novel masked prime 37 paradoxically facilitated the “larger” response. In these experiments task context could induce subjects to unconsciously process only the leftmost masked prime digit, only the rightmost digit, or both independently. Across 3 experiments, subliminal priming was governed by both task context and long-term semantic memory. (shrink)
Many studies show that punishment, although able to stabilize cooperation at high levels, destroys gains which makes it less efficient than alternatives with no punishment. Standard public goods games (PGGs) in fact show exactly these patterns. However, both evolutionary theory and real world institutions give reason to expect institutions with punishment to be more efficient, particularly in the long run. Long-term cooperative partnerships with punishment threats for non-cooperation should outperform defection prone non-punishing ones. This article demonstrates that fieldwork data (...) from hunter-gatherers, common pool resource management cases and even PGGs support this hypothesis. Although earnings in PGGs with a punishment option may be lower at the beginning, efficiency increases dramatically over time. Most ten-period PGGs cannot capture this change because their time horizon is too short. (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.
Global short-term medical volunteerism is growing, and properly conducted, is a tool in the fight for greater global health equity. It is intrinsically ethical (i.e., it involves ethics at every step) and depends upon ethical conduct for its success. At present, ethical guidelines remain in their infancy, which presents a unique opportunity. This paper presents a set of basic ethical principles, building on prior work in this area and previously developed guidelines for international clinical research. The content of these (...) principles, and the benchmarks used to evaluate them, remain intentionally vague and can only be filled by collaboration with those on-the-ground in local communities where this work occurs. Ethical review must additionally take into consideration the different obligations arising from the type of institution, type of intervention, and type of relationship involved. This paper argues that frequent and formalized ethical review, conducted from the beginning with the local community (where this community helps define the terms of debate), remains the most important ethical safeguard for this work.

This paper studies long-term norms concerning actions. In Meyer's Propositional Deontic Logic (PDₑL), only immediate duties can be expressed, however, often one has duties of longer durations such as: "Never do that", or "Do this someday". In this paper, we will investigate how to amend (PDₑL) so that such long-term duties can be expressed. This leads to the interesting and suprising consequence that the long-term prohibition and obligation are not interdefinable in our semantics, while there is a (...) duality between these two notions. As a consequence, we have provided a new analysis of the long-term obligation by introducing a new atomic proposition I (indebtedness) to represent the condition that an agent has some unfulfilled obligation.

The aim of this study is to illuminate the significance of the long-term influence of bodily changes on the perception of self after stroke by means of narrative interviews with 23 stroke survivors. A phenomenological-hermeneutic approach inspired by the philosophy of Merleau-Ponty and Ricoeur is the methodological framework. Zahavi’s understanding of the embodied self and Leder’s concept of dys-appearance along with earlier research on identity guide the comprehensive understanding of the theme. The meaning of bodily changes after stroke can (...) be understood as living with an altered perception of self. Stroke survivors perceive their bodies as fragile, unfamiliar and unreliable and tend to objectify them. The weak and discomforting body that ‘cannot’ demands constant, comprehensive awareness to keep itself in play. These long-term and often permanent consequences of bodily weakness may turn stroke survivors’ intentionality inwards, away from external activities and projects and relationships with others. Negative judgements from others are added to lost roles and positions and threaten the vulnerable self. Stroke survivors try to regain familiarity with their body by their life-long project of testing its boundaries. Mastering important tasks helps them strengthen their self-concept. Health care workers should be aware of the embodied self and engage in long-term dialogues with stroke survivors to strengthen positive perceptions of body and self. More research is needed to understand destructive post-stroke phenomena such as fatigue and pain and to find effective methods to help stroke survivors regain wholeness of body and self. (shrink)
Preference for partners with low fluctuating asymmetry (FA) may produce “good gene” benefits. However, Gangestad & Simpson's analysis does not exclude immediate benefits of fertility. Low FA is related to fertility in men and women. Short-term changes in FA are correlated with fertility in women. It is not known whether temporal fluctuations in the FA of men are related to short-term fertility status.
Unified, all-purpose, philosophical models of reduction in science lack resources for capturing varieties of cross-scientific relations that have proven critical to understanding some scientific achievements. Not only do those models obscure the distinction between successional and cross-scientific relations, their preoccupations with the structures of both theories and things provide no means for accommodating the contributions to various sciences of theories and research about long-term diachronic processes involving large-scale, distributed systems. Darwin's theory of evolution by natural selection is the parade (...) case. Explanatory pluralism accommodates a wider range of connections between theories and inquiries in science than all-purpose models of reduction do. Consequently, it provides analytical tools for understanding the roles of the theoretical proposals about the evolution of the human mind/brain that have proliferated over the last two decades. Those proposals have testable implications pertaining to both structure and processing in the modern human mind/brain. An example of such research illustrates how those proposals and investigative tools and experiments cut across both explanatory levels and modes of analysis within the cognitive sciences and how those studies can yield evidence that bears on the assessment of competing theories and models.

The use of the term "experience" is rarely explained in sufficient detail to allow researchers to fully appreciate the complexity of the experience-performance relationship. The findings research in this area are difficult to interpret and often lead to unwarranted or exaggerated claims. The interpretation of the results is made difficult from problems stemming from a poorly defined and measured construct and an inadequate conceptualization of the relationship of experience to several specific dependent variables. Additionally, exposure is often misconstrued as (...) experience. This paper aims to develop a conceptual framework of experience that will be helpful in promoting consistency in the use of the term by researchers, theorists, and professionals and that will facilitate understanding of what are now confusing findings concerning the effects of experience.

There is remarkable agreement between Ruchkin et al.'s psychophysiological views and my own model, based on developmental-experimental evidence, of working memory as activated long-term memory (LTM). I construe subvocal rehearsal as an operative scheme that maintains order information and demands attentional resources. Encoding and retrieving operations also demand attention. Another share of resources is used for keeping activated specific LTM representations.
Memory and forgetting are inextricably intertwined. Any account of short-term memory (STM) should address the following question: If three, four, or five chunks are being held in STM, what happens after attention is diverted?
Cowan argues that the true short-term memory (STM) capacity limit is about 4 items. Functional neuroimaging data converge with this conclusion, indicating distinct neural activity patterns depending on whether or not memory task-demands exceed this limit. STM for verbal information within that capacity invokes focal prefrontal cortical activation that increases with memory load. STM for verbal information exceeding that capacity invokes widespread prefrontal activation in regions associated with executive and attentional processes that may mediate chunking processes to accommodate STM (...) capacity limits.

The assessment and management of pain is a significant public health problem in the United States. Long-term care facilities face unique barriers and challenges to pain management due to the large population of cognitively impaired residents, little physician contact and poor pain education for nurses and nurse assistants. In addition, common misconceptions about pain and pain treatment in the elderly along with health professional and resident fears of addiction and drug toxicity, add to the problem of pain management. The (...) basic principles of pain treatment in long-term care are identical to all other health care settings – utilizing a combination of drug and non-drug treatments. Recent efforts to institutionalize improved pain management practices, through assessment procedures and defined pain management policies, standards and education programming, is a promising venue for systemically improving pain treatment in long-term care settings.

Houston, Texas, is a major U.S. city with, like many, a growing aging population. The purpose of this study and ultimate book chapter is to explore the views and perceptions of long-term care (LTC) residents, family members and health care providers. Individuals primarily in independent living and group residential settings were interviewed and studied. Questions emphasized the concepts of personal autonomy, dignity, quality and location of care and decision making. Although a small sample of participants were involved, consistency was (...) noted. Keeping the elderly in caring and loving home situations (theirs or family) was most preferred. Personal choice and independence were emphasized by residents, but family members needed to act as advocates. We also noted that the legal system emphasizes family control over individual decision making as competency declines with aging. Optimal personal decision making in the residents' best interest also became more difficult with loss of individual mental capacity. (shrink)
I argue against Deborah Nails that Plato, like Aristotle, frequently used the term "ousia" to indicate what is ontologically fundamental, and that he did so throughout all periods of his writing.
Interpreting VTA dopamine activity as a facilitator of affective engagement fits Depue & Collins's agency dimension of extraverted personality and also Watson's and Tellegen's (1985) engagement dimension of state mood. Serotonin, by turning down the gain on dopaminergic affective engagement, would permit already prepotent responses or habits to prevail against the behavior-switching incentive-simulation-driven temptations of the moment facilitated by fickle VTA DA. Intelligent switching between openly responsive affective engagement and constraint by long-term plans, goals, or values presumably involves environment-sensitive (...) balancing of these neuromodulators, such as socially dominant primates may show.

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.
The view that short-term memory should be conceived of as being a process based on the activation of long-term memory is inconsistent with neuropsychological evidence. Data from brain-damaged patients, showing specific patterns of impairment, are compatible with a vision of memory as a multiple-component system, whose different aspects, in neurologically unimpaired subjects, show a high degree of interaction.
Economic markets are not morally free zones. Contrary to popular misconceptions, market functioning rests on the ethical principles of fairness and voluntariness. This ethical foundation can be traced back at least to moral philosopher Adam Smith, one of the founders of modern economics. In the inconspicuous form of microeconomic axioms, these moral foundations are preserved. Thus, virtually all “neo-classic” economic concepts presuppose a market ethics of fairness and voluntariness. In a world of pervasive uncertainty on the long-term development of (...) the human-environment interaction, the protection of the global life-support systems is an important test case for the scope of the ethical content of market ethics. We review risk protection strategies in the face of this uncertainty that are (i) based on the insurance effect of biological diversity, and (ii) that employ a safe minimum standard (SMS). Because the fairness principle of market ethics requires that economic agents who cause “external” costs must, at least, compensate those who are burdened with these costs, the interests of future generations have to be included in responsible economic decision-making. The market and market ethics approach is applied to the analysis of a SMS for biological diversity, and to the inherent problems of such an approach. At the microeconomic level of individual decision-making, an unconditional protection is supported by market ethics neither for the putative interests of future generations nor for biological diversity: Poor people who struggle to cover their basic needs cannot not be required to care for biological diversity. In all other cases, the protection of biological diversity in favour of future generations is supported—if costs are not “unacceptably high”. At which cost level this point is approached, market ethics is not designed to decide. (shrink)
The term "false memories" has been used to refer to suggestibility experiments in which whole events are apparently confabulated and in media accounts of contested memories of childhood abuse. Since 1992 psychologists have increasingly used the term "false memory" when discussing memory errors for details, such as specific words within word lists. Use of the term to refer to errors in details is a shift in language away from other terms used historically (e.g., "memory intrusions"). We empirically (...) examine this shift in language and discuss implications of the new use of the term "false memories." Use of the term presents serious ethical challenges to the data-interpretation process by encouraging over-generalization and misapplication of research findings on word memory to social issues.

Many powerful logics exist today for reasoning about multi-agent systems, but in most of these it is hard to reason about an infinite or indeterminate number of agents. Also the naming schemes used in the logics often lack expressiveness to name agents in an intuitive way.To obtain a more expressive language for multi-agent reasoning and a better naming scheme for agents, we introduce a family of logics called term-modal logics. A main feature of our logics is the use of (...) modal operators indexed by the terms of the logics. Thus, one can quantify over variables occurring in modal operators. In term-modal logics agents can be represented by terms, and knowledge of agents is expressed with formulas within the scope of modal operators. (shrink)
Future work is needed to establish that pure short-term memory is a coherent individual difference attribute that is separable from traditional compound short-term memory measures. Psychometric support for latent pure short-term memory capacity will provide an important starting point for future fine-grained analyses of the intrinsic factors that influence individual differences in math skills.
Over the past few decades, there has been increasing attention focused on the ethics of health research, particularly in low- and middle-income countries. Despite the increasing focus on the literature addressing human protection, community engagement, appropriate consent procedures and ways to mitigate concerns around exploitation, there has been little discussion about how the duration of the research engagement may affect the ethical design and implementation of studies. In other words, what are the unique ethical challenges when researchers engage with host (...) communities for longer periods (10 years or more), and what special considerations does this time commitment generate when applying ethical principles to these kinds of studies? This article begins to outline key areas of ethical concern that arise during long-term, sustained research activities with communities in low-resource settings. Through a review of the literature and consultations with experts in health systems, we identified the following key themes: fair benefits and long-term beneficence; community autonomy, consultation and consent; impacts on local health systems; economic impacts of research participation; ethical review processes; and institutional processes and oversight within research organizations. We hope that this preliminary exploration will stimulate further dialogue and help inform ethical guidance around long-term research engagements in the developing world. (shrink)
Regardless of the increased interest in technological innovation in universities, relatively little is known about the technology developed by academic scientists. Long-term analyses of researchers’ technological contribution are notably missing. This paper examines university-based technology in Finland during the period 1900–85. The focus is on the quantity and technological specialization of applications created inside the universities and in the changes that occurred in scientists’ technological output over nine decades. In the long-term analysis several aspects in universities’ technological contribution, (...) which are typically considered a recent phenomenon, turn out to have long historical roots. Thus the empirical evidence provided in the article challenges views emphasising that the world of science has faced a drastic change in recent decades. (shrink)
This paper proposes a revised Theory of Moves (TOM) to analyze matrix games between two players when payoffs are given as ordinals. The games are analyzed when a given player i must make the first move, when there is a finite limit n on the total number of moves, and when the game starts at a given initial state S. Games end when either both players pass in succession or else a total of n moves have been made. Studies are (...) made of the influence of i, n, and S on the outcomes. It is proved that these outcomes ultimately become periodic in n and therefore exhibit long-term predictable behavior. Efficient algorithms are given to calculate these ultimate outcomes by computer. Frequently the ultimate outcomes are independent of i, S, and n when n is sufficiently large; in this situation this common ultimate outcome is proved to be Pareto-optimal. The use of ultimate outcomes gives rise to a concept of stable points, which are analogous to Nash equilibria but consider long-term effects. If the initial state is a stable point, then no player has an incentive to move from that state, under the assumption that any initial move could be followed by a long series of moves and countermoves. The concept may be broadened to that of a stable set. It is proved that every game has a minimal stable set, and any two distinct minimal stable sets are disjoint. Comparisons are made with the results of standard TOM. (shrink)
Long-term ecological research (LTER), addressing problems that encompass decadal or longer time frames, began as a formal term and program in the United States in 1980. While long-term ecological studies and observation began as early as the 1400s and 1800s in Asia and Europe, respectively, the long-term approach was not formalized until the establishment of the U.S. long-term ecological research programs. These programs permitted ecosystem-level experiments and cross-site comparisons that led to insights into the biosphere’s (...) structure and function. The holistic ecosystem approach of this initiative also allowed the incorporation of the human-dimension of ecology and recently has given rise to a new concept of long-term socio-ecological research (LTSER). Today, long-term ecological research programs exist in at least thirty-two countries (i.e., members of the International Long-Term Ecological Research Network, ILTER). However, consolidation of the international network within the long-term socio-ecological research paradigm still requires: (1) inclusion of certain remote regions of the world, such as southwestern South America, that are still poorly represented; (2) modifications of the type of research conducted, such as integrating social and natural sciences with the humanities and ethics; and (3) the incorporation of findings and results into broader social and political processes. In this context, a nascent long-term socio-ecological research network in Chile, which extends over the longest latitudinal range of temperate forest in the Southern Hemisphere, adds a new remote region to international long-term ecological research previously overlooked. In addition, collaboration with the University of North Texas and other international partners helps to further develop an interdisciplinary approach for the integration of the ecological sciences and environmental philosophy together with traditional ecological knowledge, informal and formal education, policy, the humanities, socio-political processes, and biocultural conservation.

Analysis of the use of the key term the people shows that it has varied both semantically and syntactically along the time-line of the evolution of the CPC.
Ruchkin et al. make a strong claim about the neural substrates of active information. Some qualifications on that conclusion are: (1) Long-term memories and neural substrates activated for perception of information are not the same thing; (2) humans are capable of retaining novel information in working memory, which is not long-term memory; (3) the content of working memory, a dynamically bound representation, is a quantity above and beyond the long-term memories activated, or the activity in perceptual substrates.
We discuss the role of short-term auditory verbal storage within a working memory system. Data from single case studies of patients with left parietal lesions and selective impairment of memory span are discussed in order to address the question of the functions of short-term memory in language processing. The backup resource of auditory verbal short-term memory is required for those tasks that necessitate backtracking in order to integrate a verbal message within a developing central cognitive representation.
Although we find Gangestad & Simpson's argument intriguing, we question some of its underlying assumptions, including: (1) that fluctuating asymmetry (FA) is consistently heritable; (2) that symmetry is driving the effects; (3) that use of parametric tests with FA is appropriate; and (4) that a short-term mating strategy produces more offspring than a long-term strategy.
Lapses in ethical conduct by those in corporate and public authority worldwide have given business researchers and practitioners alike cause to re-examine the antecedents to personal ethical values. We explore the relationship between ethical values and an individual’s long-term orientation or LTO, defined as the degree to which one plans for and considers the future, as well as values traditions of the past. Our study also examines the role of work ethic and conservative attitudes in the formation of a (...) person’s long-term orientation and consequent ethical beliefs. Empirically testing these hypothesized relationships using data from 292 subjects, we find that long-term perspectives on tradition and planning indeed engender higher levels of ethical values. The results also support work ethic’s role in fostering tradition and planning, as well as conservatism’s positive association with planning. Additionally, we report how tradition and planning mediate the influence of conservatism and work ethic on the formation of ethical values. Limitations of the study and future research directions, as well as implications for business managers and academics, are also discussed. (shrink)
The problem this paper is concerned with is the politics of reforming embedded, parasitic, sometimes predatory, networkbased,corruption subsystems. The politics of corruption subsystems is often embedded in social structures sustained by the collectiveaction of interest groups who benefit from the corruption. Therefore, the long-term effectiveness of approaches that focus solely onisolated, individual acts of corruption are limited. The politics of long-term corruption reform can benefit from a combined action-learning and social movement–based collective approach.
Although visual long-term memory (VLTM) and visual short-term memory (VSTM) can be distinguished from each other (and from visual sensory storage [SS]), they are embodied within the same modality-specific brain regions, but in very different ways: VLTM as patterns of connectivity and VSTM as patterns of activity. Perception and VSTM do not “activate” VLTM. They use VLTM to create novel patterns of activity relevant to novel circumstances.
The identity of working-memory and long-term memory representations follows from many lines of evidence. However, the data provided by Ruchkin et al. are hardly compelling, as they make unproved assumptions about hypothetical generators. We cite studies from our lab in which congruent slow-wave topographies were found for short-term and long-term memory tasks, strongly suggesting that both activate identical cell assemblies.
I is perhaps the most important and the least understood of our everyday expressions. This is a constant source of philosophical confusion. Max de Gaynesford offers a remedy: he explains what this expression means, its logical form and its inferential role. He thereby shows the way to an understanding of how we express first-personal thinking. He dissolves various myths about how I refers, to the effect that it is a pure indexical. His central claim is that the key to understanding (...) I is that it is the same kind of expression as the other singular personal pronouns, you and he/she: a deictic term, whose reference depends on making an individual salient. He addresses epistemological questions as well as semantic questions, and shows how they interrelate. The book thus not only resolves a key issue in philosophy of language, but promises to be of great use to people working on problems in other areas of philosophy. (shrink)
We challenge Ruchkin et al.'s claim in reducing short-term memory (STM) to the active part of long-term memory (LTM), by showing that their data cannot rule out the possibility that activation of posterior brain regions could also reflect the contribution of a verbal STM buffer.
Shors & Matzel's target article is a thought-provoking attempt to reconceptualise long-term potentiation as an attentional or arousal mechanism rather than a memory storage mechanism. This is incompatible with the facts of the neurobiology of attention and of the behavioural neurophysiological properties of hippocampal neurons.
We provide additional support for Cowan's claim that short term memory (STM) involves a range of 3–5 tokens, on the basis of language correlational analyses. If language is at least partly learned, linguistic dependency structure should reflect properties of the cognitive components mediating learning; one such component is STM. In this view, the range over which statistical regularity extends in ordinary text would be suggestive of STM span. Our analyses of eight languages are consistent with STM span being about (...) four chunks. (shrink)
The basic notions of the theory of term rewriting are defined for terms that may involve function letters of infinite arity. A sufficient condition for completeness is derived, and its use demonstrated by the example of abstract clones over infinitary signatures.
Cowan defines a chunk as “a collection of concepts that have strong associations to one another and much weaker associations to other chunks currently in use.” This definition does not impose any constraints on the nature and number of elements that can be bound into a chunk. We present an experiment to demonstrate that such limitations exist for visual short-term memory, and that their analysis may lead to important insights into properties of visual memory.
There are over 800 seventh to tenth grade students at the College d’Enseignment Generale (CEG) School in Azové, Benin. Like most children in the developing world, these students lack access to clean water and basic sanitation facilities.

Promoting proper sanitation and providing the technology to implement water and wastewater treatment in the community will decrease childhood (...) and maternal disease and mortality rates in Azové. However, these measures may take several years to implement and will require a significant investment in the infrastructure of the school.

This commentary focuses on how bottom-up neocortical models can be developed into eigenfunction expansions of probability distributions appropriate to describe short-term memory in the context of scalp EEG. The mathematics of eigenfunctions are similar to the top-down eigenfunctions developed by Nunez, despite different physical manifestations. The bottom-up eigenfunctions are at the local mesocolumnar scale, whereas the top-down eigenfunctions are at the global regional scale. Our respective approaches have regions of substantial overlap, and future studies may expand top-down eigenfunctions into (...) the bottom-up eigenfunctions, yielding a model of scalp EEG expressed in terms of columnar states of neocortical processing of attention and short-term memory.

Fieldworkers (FWs) are community members employed by research teams to support access to participants, address language barriers, and advise on culturally appropriate research conduct. The critical role that FWs play in studies, and the range of practical and ethical dilemmas associated with their involvement, is increasingly recognised. In this paper, we draw on qualitative observation and interview data collected alongside a six month basic science study which involved a team of FWs regularly visiting 47 participating households in their homes. The (...) qualitative study documented how relationships between field workers and research participants were initiated, developed and evolved over the course of the study, the shifting dilemmas FWs faced and how they handled them. Even in this one case study, we see how the complex and evolving relationships between fieldworkers and study participants had important implications for consent processes, access to benefits and mutual understanding and trust. While the precise issues that FWs face are likely to depend on the type of research and the context in which that research is being conducted, we argue that appropriate support for field workers is a key requirement to strengthen ethical research practice and for the long term sustainability of research programmes.

Many still seem confident that the kind of semantic theory Putnam once proposed for natural kind terms is right. This paper seeks to show that this confidence is misplaced because the general idea underlying the theory is incoherent. Consequently, the theory must be rejected prior to any consideration of its epistemological, ontological or metaphysical acceptability. Part I sets the stage by showing that falsehoods, indeed absurdities, follow from the theory when one deliberately suspends certain devices Putnam built into it , (...) presumably in order to block such entailments. Part II then raises the decisive issue of at what cost these devices do the job they need to do. It argues that - apart from possessing no other motivation than their capacity to block the consequences derived in Part I - they only fulfil this blocking function if they render the theory unable to deal with fiction and related 'make-believe' activities. Part III indicates the affinity Putnam's account has with the classically 'denotative' view of meaning, and thus how its weaknesses may be seen as a variant of the classical weakness of 'denotative' approaches. It concludes that the theory is a conceptual muddle. (shrink)
Kripke and Putnam have convinced most philosophers that we cannot do metaphysics of nature by analysing the senses of natural kind terms -- simply because natural kind terms do not have senses. Neo-descriptivists, especially Frank Jackson and David Chalmers, believe that this view is mistaken. Merging classical descriptivism with a Kaplan-inspired two-dimensional framework, neo-descriptivists devise a semantics for natural kind terms that assigns natural kind terms so-called 'primary intensions'. Since primary intensions are senses by other names, Jackson and Chalmers conclude (...) that we can and should do metaphysics of nature by analysing the natural kind concepts competent speakers possess. I argue that neo-descriptivism does not provide a suitable basis for doing this kind of metaphysics. I first of all give a detailed account of the neo-descriptivist semantics and deflate the intuitive support neo-descriptivists try to draw from their case of the XYZ-world. I then present three arguments -- the Argument from Ignorance, the Argument from Conceptual Analysis, and the Argument from Laziness. Taken together, these arguments undermine the neo-descriptivist analysis of natural kind terms. I conclude that natural kind terms do not have senses, that we cannot do metaphysics of nature by analysing the senses of our kind terms, and that the Kripke-Putnam account still provides the best semantics for natural kind terms we have.

The question whether numbers are objects is a central question in the philosophy of mathematics. Frege made use of a syntactic criterion for objethood: numbers are objects because there are singular terms that stand for them, and not just singular terms in some formal language, but in natural language in particular. In particular, Frege (1884) thought that both noun phrases like the number of planets and simple numerals like eight as in (1) are singular terms referring to numbers as abstract (...) objects.

Are sensation ascriptions descriptive, even in the first person present tense? Do sensation terms refer to, denote, sensations, so that truth and falsity of sensation ascriptions depend on the properties of the denoted sensations?

Wittgenstein rejects the idea of a denotational semantics for public language sensation terms, such as.
In his recent article, ``Self-Consciousness', George Bealer has set outa novel and interesting argument against functionalism in the philosophyof mind. I shall attempt to show, however, that Bealer's argument cannotbe sustained.In arguing for this conclusion, I shall be defending three main theses.The first is connected with the problem of defining theoreticalpredicates that occur in theories where the following two features arepresent: first, the theoretical predicate in question occurswithin both extensional and non-extensional contexts; secondly, thetheory in question asserts that the relevant (...) theoretical states enterinto causal relations. What I shall argue is that a Ramsey-styleapproach to the definition of such theoretical terms requires twodistinct quantifiers: one which ranges over concepts, and theother which ranges over properties in the world.

This paper offers a new concept of the firm that aims at balancing the corporate economic, social, and environmental responsibilities and goes beyond the stakeholder approach. It intends to provide a conceptual and operationalizable basis to fairly assess corporate conduct from both inside and outside the companies. To a large extent these different responsibilities may overlap and reinforce each other. However, if they conflict, they should be clearly evaluated for their own sake and in terms of wealth creation. Only then (...) can a balanced approach be realized. Section 1 briefly discusses some general aspects of the relationship between concepts and measurement. In Section 2, a concept of the firm is developed that is based on the notion of responsibility and balances economic, social and environmental responsibilities. According to these concepts, different ways of measuring corporate planning and performance are examined in Section 3, followed up by a summary and conclusions. (shrink)
abstract. A first-order dynamic epistemic logic is developed where the names of the agents are also terms in the sense of first-order logic. Consequently one can quantify over epistemic modalities. Us- ing constructs from dynamic logic one can express many interesting concepts. First-order update models are developed and added to the language as modalities.
It is shown that the evolution of physics canin several regards be described by elements of``regression'', i.e., that within a certaintradition of ideas one begins with theconstruction of most ``plausible'' statements(axioms) at hand, and then ``works onselfbackwards'' with respect to developmental terms.As a consequence of this strategy, the furtherwork proceeds along such a ``regressive'' path,the more one arrives at concepts andrelationships which are unexpected or evencounter-intuitive in terms of our everydayexperiences. However, a comparable phenomenology is wellknown from studies on states (...) of consciousness.In particular, the evolutionary logic of theconstructions of major ``cognitive invariances''in physics, which is in part due to everincreasing rates of data processing, ismirrored in a logic of states of consciousnesswhich deviate from a ``normal'' state of dailyroutine along increasing levels of centralnervous arousal. Examples are given from the evolution ofphysics, and future perspectives are brieflyoutlined on the basis thereof. (shrink)
Climate sensitivity is commonly taken to refer to the equilibrium change in the annual mean global surface temperature following a doubling of the atmospheric carbon dioxide concentration. Evaluating this variable remains of significant scientific interest, but its global nature makes it largely irrelevant to many areas of climate science, such as impact assessments, and also to policy in terms of vulnerability assessments and adaptation planning. Here, we focus on local changes and on the way observational data can be analysed to (...) inform us about how local climate has changed since the middle of the nineteenth century. Taking the perspective of climate as a constantly changing distribution, we evaluate the relative changes between different quantiles of such distributions and between different geographical locations for the same quantiles. We show how the observational data can provide guidance on trends in local climate at the specific thresholds relevant to particular impact or policy endeavours. This also quantifies the level of detail needed from climate models if they are to be used as tools to assess climate change impact. The mathematical basis is presented for two methods of extracting these local trends from the data. The two methods are compared first using surrogate data, to clarify the methods and their uncertainties, and then using observational surface temperature time series from four locations across Europe.

This paper discusses whether it can be known a priori that a particular term, such as water, is a natural kind term, and how this problem relates to Putnams claim that natural kind terms require an externalist semantics. Two conceptions of natural kind terms are contrasted: The first holds that whether water is a natural kind term depends on its a priori knowable semantic features. The second.

The paper argues that it is through advancing and revising what are likely to be overly simplistic and incorrect decompositions that (...) the goals of cognitive neuroscience are likely to be achieved.
