This paper tries to show that ontology is one of the important tendencies in the future philosophy. The author thinks that ontology as the basic spirit makes philosophy be different from other subjects. Ontology originates from people’s examination to essence of the world. However, ancient long-term argument couldn’t get any clear conclusion. So philosophers gradually understand that ontology is connected with epistemology. If we want to make a good explanation to ontology, we must return to check ourselves cognition. And (...) the epistemology turns into the main stream of the philosophy Since Descartes. But this doesn’t mean ontology being disappeared. It only tends from the stage to background. In fact, the discussion of the linguistic philosophy still belongs to epistemology. As a whole, we can say philosophy really goes though one negative development. According to dialectic, negation of negation is a universal law. The philosophy has to undergo another inevasible reform and return to ontology again. Many contemporary philosophers have regarded this and begin to do it effectively. (shrink)
Ethical consumption is on the rise, however little is known about the degree and the implications of the sometime conflicting sets of values held by the broad category of consumers who report consuming ethically. This paper explores convergence and divergence of ethical consumption values through a study of organic, fair trade, and local food consumers in Colorado. Using survey and focus group results, we first examine demographic and attitudinal correlates of ethical consumption. We then report evidence that while many organic, (...) fair trade, and local food consumers converge around similar values, some Colorado consumers support only local food, while opposing the consumption of organic and fair trade products. Next, we investigate how ethical consumers who converge and diverge frame their commitment to consuming ethically. The discussion and conclusion suggest that community development planners of projects that focus on ethical consumption will need to successfully traverse issues stemming from convergence and divergence to enjoy long-term sustained success.

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-termpotentiation (LTP) (an important type of synaptic plasticity in mammalian hippocampus and cortex). (shrink)
Shors & Matzel's target article is a thought-provoking attempt to reconceptualise long-termpotentiation 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.
The phenomenon of synesthesia has undergone an invigoration of research interest and empirical progress over the past decade. Studies investigating the cognitive mechanisms underlying synesthesia have yielded insight into neural processes behind such cognitive operations as attention, memory, spatial phenomenology and inter-modal processes. However, the structural and functional mechanisms underlying synesthesia still remain contentious and hypothetical. The first section of the present paper reviews recent research on grapheme-color synesthesia, one of the most common forms of synesthesia, and addresses the ongoing (...) debate concerning the role of selective attention in eliciting synesthetic experience. Drawing on conclusions of the first half, the paper’s second half examines the various models proposed to explain the cognitive mechanisms behind grapheme-color synesthesia, and discusses the explanatory virtues of a new model suggesting that grapheme-color synesthesia is grounded in memory. The last section offers an examination of some of the broader philosophical implications of synesthesia. (shrink)
Shors & Matzel set up a straw man, that LTP is a memory storage mechanism, and knock him down without due consideration of the important relations among different levels of organization and analysis regarding LTP, learning, and memory. Assessing these relationships requires analysis and hypotheses linking specific brain regions, neural circuits, plasticity mechanisms, and task demands. The issue addressed by the authors is important, but their analysis is off target.
Shors & Matzel propose that hippocampal LTP increases the effective salience of discrete external stimuli and thereby facilitates the induction of memories at distant places. In line with this suggestion, a neural network model of associative learning and hippocampal function assumes that LTP increases hippocampal error signals to the cortex, thereby facilitating stimulus configuration in association cortex. Computer simulations show that under these assumptions the model correctly describes the effect of LTP induction and blockade in classical discriminations and place learning.
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)
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.
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)
It is argued that John Bickle’s Ruthless Reductionism is flawed as an account of the practice of neuroscience. Examples from genetics and linguistics suggest, first, that not every mind-brain link or gene-phenotype link qualifies as a reduction or as a complete explanation, and, second, that the higher (psychological) level of analysis is not likely to disappear as neuroscience progresses. The most plausible picture of the evolving sciences of the mind-brain seems a patchwork of multiple connections and partial explanations, linking anatomy, (...) mechanisms and functions across different domains, levels, and grain sizes. Bickle’s claim that only the molecular level provides genuine explanations, and higher level concepts are just heuristics that will soon be redundant, is thus rejected. In addition, it is argued that Bickle’s recasting of philosophy of science as metascience explicating empirical practices, ignores an essential role for philosophy in reflecting upon criteria for reduction and explanation. Many interesting and complex issues remain to be investigated for the philosophy of science, and in particular the nature of interlevel links found in empirical research requires sophisticated philosophical analysis.

As opposed to the dismissive attitude toward reductionism that is popular in current philosophy of mind, a “ruthless reductionism” is alive and thriving in “molecular and cellular cognition”—a field of research within cellular and molecular neuroscience, the current mainstream of the discipline. Basic experimental practices and emerging results from this field imply that two common assertions by philosophers and cognitive scientists are false: (1) that we do not know much about how the brain works, and (2) that lower-level neuroscience cannot (...) explain cognition and complex behavior directly. These experimental practices involve intervening directly with molecular components of sub-cellular and gene expression pathways in neurons and then measuring specific behaviors. These behaviors are tracked using tests that are widely accepted by experimental psychologists to study the psychological phenomenon at issue (e.g., memory, attention, and perception). Here I illustrate these practices and their importance for explanation and reduction in current mainstream neuroscience by describing recent work on social recognition memory in mammals. (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.

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)
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.

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.
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)
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.

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.
. 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)
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)

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)
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.

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)
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.

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.
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)
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)
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.

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.
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.
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.
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.
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. These students suffer from parasitic infection and health ailments which could be directly offset with short term aid to supply water and medical aid. 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. Is it ethical to spend $10,000 towards the long-term goals of providing water and sanitation to the students of CEG Azové, compared to spending the same amount on short-term relief efforts? (shrink)
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)
Not by Genes Alone excellently explains Peter J. Richerson and Robert Boyd's important ideas about human gene-culture co-evolution to a broader audience but remains short of a larger vision of civilization. Several decades ago Ralph Burhoe had seen that fertile possibility in Richerson and Boyd's work. I suggest getting past present reductionistic customs to a scientific perspective having an integral place for virtue. Subsystem agency is part of this view, as is the driving role of abundance, whose ultimate origins are (...) in the mysterious, quintessentially energetic Big Bang. The free-rider problem may not impede higher social organization as inexorably as Richerson and Boyd believe; "the tragedy" of enervating leakage from "the commons" may often be less influential than an invigorating flow of externalities to the commons. Eukaryotic origins mark the origin of inevitable wider sharing as higher living systems evolve. I use a metaphor of flesh and spirit in drawing a parallel between that turning point and the wide sharing that occurs in civilization. This helps solve the enigma of the demographic transition. Why do so many productive participants in first-world societies severely restrict their selfish-gene reproduction to below replacement birth rate? It is not because culture is maladaptive but because civilization's brain and womb have become partially differentiated in distinct populations. Considerations of social boundaries, myths of sacrifice, and human creativity help in understanding how human social evolution taps potentials present in reality. Human beings' diverse vigorous activities—the organized ones and the inadvertent ones, the wise and the foolish, the good and the bad, the carefully thoughtful and the merely playful—provide the ground of being, or primordial soup, for cultural entities that transcend our intentions. If we have it right for the most part and are fortunate, we will continue to emerge at higher levels. (shrink)
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)
The metric devised by Halford, Wilson & Phillips may have considerable potential in distinguishing between the working memory demands of different tasks but may be less effective in distinguishing working memory capacity between individuals. Despite the strengths of the metric, determining whether an effect is caused by relational complexity or by differential levels of expertise is currently problematic.
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 defends cognitive neuroscience’s project of developing mechanistic explan- ations of cognitive processes through decomposition and localization against objections raised by William Uttal in The New Phrenology. The key issue between Uttal and researchers pursuing cognitive neuroscience is that Uttal bets against the possibility of decomposing mental operations into component elementary operations which are localized in distinct brain regions. 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.

The problem of cortical integration is described and various proposed solutions, including grandmother cells, cell assemblies, feed-forward structures, RAAM and synchronization, are reviewed. One method, involving complex attractors, that has received little attention in the literature, is explained and developed. I call this binding through annexation. A simulation study is then presented which suggests ways in which complex attractors could underlie our capacity to reason. The paper ends with a discussion of the efficiency and biological plausibility of the proposals as (...) integration mechanisms for different regions and functions of the brain. (shrink)
Ethics researchers advise managers of organizations to link rewards and punishments to ethical and unethical behavior, respectively. We build on prior research maintaining that organizations operate at Kohlbergs stages of moral reasoning, and explain how the over-reliance on rewards and punishments encourages employees to operate at Kohlbergs lowest stages of moral reasoning. We advocate designing organizations as ethical communities and relying on different assumptions about employees in order to foster ethical reasoning at higher levels. Characteristics associated with ethical communities are (...) identified and AES Corporation and Semco S/A serve as examples of corporations exhibiting the design characteristics and assumptions of ethical organizations.

This article addresses prospective and retrospective responsibility issues connected with medical robotics. It will be suggested that extant conceptual and legal frameworks are sufficient to address and properly settle most retrospective responsibility problems arising in connection with injuries caused by robot behaviours (which will be exemplified here by reference to harms occurred in surgical interventions supported by the Da Vinci robot, reported in the scientific literature and in the press). In addition, it will be pointed out that many prospective responsibility (...) issues connected with medical robotics are nothing but well-known robotics engineering problems in disguise, which are routinely addressed by roboticists as part of their research and development activities: for this reason they do not raise particularly novel ethical issues. In contrast with this, it will be pointed out that novel and challenging prospective responsibility issues may emerge in connection with harmful events caused by normal robot behaviours. This point will be illustrated here in connection with the rehabilitation robot Lokomat. (shrink)
A world product time series covering two million years is well fit by either a sum of four exponentials, or a constant elasticity of substitution (CES) combination of three exponential growth modes: “hunting,” “farming,” and “industry.” The CES parameters suggest that farming substituted for hunting, while industry complemented farming, making the industrial revolution a smoother transition. Each mode grew world product by a factor of a few hundred, and grew a hundred times faster than its predecessor. This weakly suggests that (...) within the next century a new mode might appear with a doubling time measured in days, not years. (shrink)
This paper seeks to provide a historically well-informed analysis of an important post-Newtonian area of research in experimental physics between 1798 and 1898, namely the determination of the mean density of the earth and, by the end of the nineteenth century, the gravitational constant. Traditionally, research on these matters is seen as a case of ‘puzzle solving.’ In this paper, I show that such focus does not do justice to the evidential significance of eighteenth- and nineteenth-century experimental research on the (...) mean density of the earth and the gravitational constant. As Newton’s theory of universal gravitation was mainly based on astronomical observation, it remained to be shown that Newton’s law of universal gravitation did not break down at terrestrial distances. In this context, Cavendish’ experiment and related nineteenth-century experiments played a decisive role, for they provided converging and increasingly stronger evidence for the universality of Newton’s theory of gravitation. More precisely, I shall argue that, as the accuracy and precision of the experimental apparatuses and the procedures to eliminate external disturbances involved increasingly improved, the empirical support for the universality of Newton’s theory of gravitation improved correspondingly.

Medical technologies and assistive devices such as ventilators and power wheelchairs are designed to sustain life and/or improve functionality but they can also contribute to stigmatization and social exclusion. In this paper, drawing from a study of ten men with Duchenne muscular dystrophy, we explore the complex social processes that mediate the lives of persons who are dependent on multiple medical and assistive technologies. In doing so we consider the embodied and emplaced nature of disability and (...) how life is lived through bodies coupled with technologies and experienced as 'techno-body-subjects in situ'. Normative implications for theory and research, including bioethics research, are discussed. (shrink)
Neither environmental economics nor environmental philosophy have adequately examined the moral implications of imposing environmental degradation and ecosystem instability upon our descendants. A neglected aspect of these problems is the supposed extent of the burden that the current generation is placing on future generations. The standard economic position on discounting implies an ethicaljudgment concerning future generations. If intergenerational obligations exist, then two types of intergenerational transfer must be considered: basic distributional transfers and compensatory transfers. Basic transfers have been the central (...) intergenerational concern of both environmental economics and philosophy, but compensatory transfers emphasize obligations of a kind often disregarded.

The experience of free will has causal consequences, albeit not immediate ones. Although Wegner recognizes this, his model failed to incorporate this causal link. Is this experience central to “what makes us human”? A broad acceptance of Wegner's claim that free will is illusory has significant societal and religious consequences, therefore the threshold of evidence needs to be correspondingly high.
With reference to Ruchkins et al.'s framework, this commentary briefly considers the history of working memory, and whether, heuristically, this is a useful concept. A neuropsychologically motivated critique is offered, specifically with regard to the recent trend for working-memory researchers to conceptualise this capacity more as a process than as a set of distinct task-specific stores.
In this commentary, we focus on four points. First, we discuss the assertion that the unitary model explains dissociations that implicate multiple systems. Second, the distinct nature of information utilized in immediate- and delayed-recall supports the distinct memory systems view. Third, the variable nature of capacity limits corroborates this view. Finally, we review event-related fMRI results that suggest support for multiple systems.
Population aging is affecting all regions and most countries (WHO 2006a; Weinberger 2007). From 2000 to 2050, the world population aged sixty and above will more than triple from 600 million to 2 billion, moving from 9 percent to as much as 22 percent of the world’s population. Projections further suggest that elderly populations in many developing countries are growing more rapidly than those in affluent ones. Compared to wealthier countries, low- and middle-income countries will undergo this demographic shift quite (...) quickly, even as they continue to contend with the burden of diseases like HIV/AIDS and tuberculosis, and do so with considerably less in the way of resources, including human resources (Weinberger ..

In this paper I will examine how the Mental Capacity Act 2005 regulates the assessment of decision-making capacity in England and Wales. I will argue that there are difficulties in reconciling the Act with how people make decisions in practice. I will explore how ideas from the ethics of care and from phenomenology can be used to take better account of how capacity flows from a person's relationships as well as their individual abilities. I will conclude by discussing some of (...) the ethical issues that have arisen in my assessments of decision-making capacity and how I have tried to respond. (shrink)
