We review recent anticipatory looking and violation-of-expectancy studies suggesting that infants and young preschoolers have spontaneous (implicit) understanding of mind despite their known problems until later in life on elicited (explicit) tests of false-belief reasoning. Straightforwardly differentiating spontaneous and elicited expressions of complex mental state understanding in relation to an implicit-explicit knowledge framework may be challenging; early action predictions may be based on behavior rules that are complementary to the mentalistic attributions under consideration. We discuss that the way forward for (...) diagnosing early mentalism is to analyze whether young candidate mind-readers’ visual orienting cohere across different belief-formation by belief-use combinations. Adopting this formal cognitive analysis, we conclude that whilst some studies come tantalizingly close to sign-posting mentalism in infants and young children’s spontaneous responses, the bulk of evidence for early mentalism grades into behaviorism.

The UK Government is presently conducting a consultation process focused on the introduction of a new legal form of company, that of the Community Interest Company (CIC). Organisations choosing this form of incorporation would be subject to a legal requirement to involve their stakeholders in the governance of the company. This development is just the latest example of an increased interest generally in making companies more responsive to their stakeholders. The statutory duty placed on companies taking the CIC form raises (...) the possibility of further legislation being introduced to compel all companies to involve their stakeholders more formally in their governance. This paper examines the participation model of stakeholder involvement proposed in the CIC legislation. This model is already widely employed in the not-for-profit company sector. A comparison is made with the engagement model of stakeholder management which is the most popular form found within the corporate sector. Conclusions are subsequently drawn about the appropriateness of a participation model for corporations in the for-profit sector by examining the challenges that emerge from giving stakeholders such a prominent role in the strategic management of the organisation.

Research into consciousness has now become respectable, and much has been written about it. Is consciousness the exclusive property of human beings, or can it be found also in animals? Can machines become conscious? Is consciousness an illusion, and are all mental states ultimately reducible to the movement of molecules? If consciousness is other than matter, what connection does it have with matter? These and others like them are now serious scientific questions in the West. This article discusses consciousness within (...) the frame of the following assertions: Consciousness has evolved from earlier states of awareness to be found in lower forms of life. The current scientific method is too restrictive for the study of conscience and its evolution. In particular classical logic leads scientists to ignore or reject consciousness as a legitimate field of study. Mind and matter, generalized as knowing and being, have equal status. (shrink)
Life, and therefore evolution, is a creative process; creativity is not an attribute of a few gifted people. The way we think obscures this truth. Three ways of dealing with a problem are creativity, calculation, and choice. Creativity can occur when a single idea is held in two contradictory frames of reference. Thus to be creative we have to put aside our usual ways of thinking, which are based on either/or. When we put aside this way of thinking we will (...) see that things do not change: they are change.

Let T be a one-based theory. We define a notion of width, in the case of T having the finiteness property, for the lattice of finitely generated algebraically closed sets and prove Theorem. Let T be one-based with the finiteness property. If T is of bounded width, then every type in T is nonorthogonal to a weight one type. If T is countable, the converse is true.
This article critically evaluates current developments in marketing fair trade labelled products and "no sweat" manufactured goods, and argues that both the fair trade and ethical trade movements increasingly rely on strategies for bottom-up change, converting consumers "one cup at a time". This individualistic approach, which we call "shopping for a better world", must, we argue, be augmented by more collectivist approaches to affect transformative change. Specifically, we look at the concept of mission-driven organizations pursuing leadership roles in developing affinity (...) relationships to promote fair and ethical trade and developing ethical spaces. Increasingly, a range of organizations are restructuring their operations, so that their mission is reflected in ethical practices throughout their operations, including product sourcing and product sales. First, ethical purchasing policies operated by non-profits and public agencies represent markets through which fair/ethical products reach end consumers. The efforts discussed to create ethical spaces through direct democracy and electoral mandate build on a broad-based affinity with the principles of fair and ethical trade. Second, we explore the potential for "mission-driven" non-profit organiza- tions, such as zoos and aquaria for merging their mission of conservation education with their marketing activities through the operation of their shops and cafes. Interesting initiatives to link the conservation message to food choices is being undertaken by a number of zoos and aquaria, while there is scope for increased linkages in the giftware sold in their shops.

The work on prototypes in ontologies pioneered by Rosch [10] and elaborated by Lakoff [8] and Freund [3] is related to vagueness in the sense that the more remote an instance is from a prototype the fewer people agree that it is an example of that prototype. An intuitive example is the prototypical “mother”, and it is observed that more specific instances like ”single mother”, “adoptive mother”, “surrogate mother”, etc., are less and less likely to be classified as “mothers” by (...) experimental subjects. From a different direction Gärdenfors [4] provided a persuasive account of natural predicates to resolve paradoxes of induction like Goodman’s “Grue” predicate [5]. Gärdenfors proposed that “quality dimensions” arising from human cognition and perception impose topologies on concepts such that the ones that appear “natural” to us are convex in these topologies. We show that these two cognitive principles — prototypes and predicate convexity — are equivalent to unimodal (convex) fuzzy characteristic functions for sets. Then we examine the case when the fuzzy set characteristic function is not convex, in particular when it is multi-modal. We argue that this is an indication that the fuzzy concept should really be regarded as a super concept in which the decomposed components are subconcepts in an ontological taxonomy. (shrink)
WHO II low grade glioma evolves inevitably to anaplastic transformation. Magnetic resonance imaging is a good non-invasive way to watch it, by hemodynamic and metabolic modifications, thanks to multinuclear spectroscopy 1 H/ 31 P. In this work we study a multi-scale minimal model of hemodynamics and metabolism applied to the study of gliomas. This mathematical analysis leads us to a fast-slow system. The control of the position of the stationary point brings to the concept of domain of viability. Starting from (...) this system, the equations bring to light the parameters that push glioma cells out of their domain of viability. Four fundamental factors are highlighted. The first two are cerebral blood flow and the rate of lactate transport through monocarboxylate transporters, which must be reduced in order to push glioma out of its domain of viability. Another factor is the intra arterial lactate, which must be increased. The last factor is pH, indeed a decrease of intra cellular pH could interfere with glioma growth. These reflections suggest that these four parameters could lead to new therapeutic strategies for the management of low grade gliomas. (shrink)
The CQUniversity Australia Human Research Ethics Committee (HREC) is a human ethics research committee registered under the auspices of the National Health and Medical Research Council. In 2009 an external review of CQUniversity Australia’s HREC policies and procedures recommended that a low risk research process be available to the institution’s researchers. Subsequently, in 2010 the Human Research Ethics Committee Low Risk Application Procedure came into operation. This paper examines the applications made under the Human Research Ethics Committee Low Risk Application (...) Procedure during the course of 2010 and 2011. The paper contributes to the literature analyzing the decision-making processes of research review committees through an analysis of the quantitative data relating to the low risk research applications made and through discourse analysis of the qualitative data represented by the assessment comments of the members of the Committee.

Jason Brennan argues that people are morally obligated not to vote badly, where voting badly is voting “without sufficient reason” for harmful or unjust policies or candidates. His argument is: (1) One has an obligation not to engage in collectively harmful activities when refraining from such activities does not impose significant personal costs. (2) Voting badly is to engage in a collectively harmful activity, while abstaining imposes low personal costs. (3) Therefore, one should not vote badly. This paper shows (...) that Brennan never adequately clarifies (1) and that, on every plausible clarification, (2) is false. (shrink)
The philosophical world is indebted to Alvin Goldman for a number of reasons, and among them, his defense of the relevance of cognitive science for philosophy of mind. In Simulating minds , Goldman discusses with great care and subtlety a wide variety of experimental results related to mindreading from cognitive neuroscience, cognitive psychology, social psychology and developmental psychology. No philosopher has done more to display the resourcefulness of mental simulation. I am sympathetic with much of the general direction of Goldman’s (...) theory. I agree with him that mindreading is not a single system based on a single mechanism. And I admire his attempt to bring together the cognitive neuroscientific discovery of mirror system phenomena and the philosophical account of pretense within a unique theoretical framework of mental simulation. To do so, Goldman distinguishes two types of mindreading, respectively, based on low-level and high-level simulation. Yet, I wonder in what sense they are really two distinct processes. Here, I will confine myself largely to spelling out a series of points that take issue with the distinction between low-level and high-level mindreading. (shrink)
This monograph provides a new account of justified inference as a cognitive process. In contrast to the prevailing tradition in epistemology, the focus is on low-level inferences, i.e., those inferences that we are usually not consciously aware of and that we share with the cat nearby which infers that the bird which she sees picking grains from the dirt, is able to fly. Presumably, such inferences are not generated by explicit logical reasoning, but logical methods can be used to describe (...) and analyze such inferences. Part 1 gives a purely system-theoretic explication of belief and inference. Part 2 adds a reliabilist theory of justification for inference, with a qualitative notion of reliability being employed. Part 3 recalls and extends various systems of deductive and nonmonotonic logic and thereby explains the semantics of absolute and high reliability. In Part 4 it is proven that qualitative neural networks are able to draw justified deductive and nonmonotonic inferences on the basis of distributed representations. This is derived from a soundness/completeness theorem with regard to cognitive semantics of nonmonotonic reasoning. The appendix extends the theory both logically and ontologically, and relates it to A. Goldman's reliability account of justified belief. This text will be of interest to epistemologists and logicians, to all computer scientists who work on nonmonotonic reasoning and neural networks, and to cognitive scientists. (shrink)
Ethical research with children requires a special concern for their well-being as individuals. Researchers are therefore expected to report problems children experience and to refer children for assistance. This article addresses difficulties that can arise as researchers attempt to meet this obligation in research with low-income ethnic minority children. Potential difficulties include both failure to report and overreporting suspected problems. The role of institutional review boards in researchers' reporting and referring behavior is also discussed.
Some risks have extremely high stakes. For example, a worldwide pandemic or asteroid impact could potentially kill more than a billion people. Comfortingly, scientific calculations often put very low probabilities on the occurrence of such catastrophes. In this paper, we argue that there are important new methodological problems which arise when assessing global catastrophic risks and we focus on a problem regarding probability estimation. When an expert provides a calculation of the probability of an outcome, they are really providing the (...) probability of the outcome occurring, given that their argument is watertight. However, their argument may fail for a number of reasons such as a flaw in the underlying theory, a flaw in the modeling of the problem, or a mistake in the calculations. If the probability estimate given by an argument is dwarfed by the chance that the argument itself is flawed, then the estimate is suspect. We develop this idea formally, explaining how it differs from the related distinctions of model and parameter uncertainty. Using the risk estimates from the Large Hadron Collider as a test case, we show how serious the problem can be when it comes to catastrophic risks and how best to address it. (shrink)
David Albert (2000) and Barry Loewer (2007) have argued that the temporal asymmetry of our concept of causal influence or control is grounded in the statistical mechanical assumption of a low-entropy past. In this paper I critically examine Albert's and Loewer's accounts.
This paper develops a formal framework to model a process in which the formation of individual opinions is embedded in a deliberative exchange with others. The paper opts for a low-resolution modeling approach and abstracts away from most of the details of the social-epistemic process. Taking a bird's eye view allows us to analyze the chances for the truth to be found and broadly accepted under conditions of cognitive division of labour combined with a social exchange process. Cognitive division of (...) labour means that only some individuals are active truth seekers, possibly with different capacities. Both mathematical tools and computer simulations are used to investigate the model. As an analytical result, the Funnel Theorem states that under rather weak conditions on the social process, a consensus on the truth will be reached if all individuals possess an arbitrarily small capacity to go for the truth. The Leading the pack Theorem states that under certain conditions even a single truth seeker may lead all individuals to the truth. Systematic simulations analyze how close agents can get to the truth depending upon the frequency of truth seekers, their capacities as truth seekers, the position of the truth (more to the extreme or more in the centre of an opinion space), and the willingness to take into account the opinions of others when exchanging and updating opinions.

The central question underlying this study was whether metacognition training could enhance the two metacognition components—knowledge and skills—and the mathematical problem-solving capacities of normal children in grade 3. We also investigated whether metacognitive training had a differential effect according to the children's mathematics level. A total of 48 participants took part in this study, divided into an experimental and a control group, each subdivided into a lower and a normal achievers group. The training programme took an interactive approach in accordance (...) with Schraw's (1998) recommendation and was carried out over five training sessions. Results indicated that children in the training group had significantly higher post-test metacognitive knowledge, metacognitive skills, and mathematical problem-solving scores. In addition, metacognitive training was particularly beneficial to the low achievers. Thus metacognitive training enabled the low achievers to make progress and solve the same number of problems on the post-test as the normal achievers solved on the pre-test. (shrink)
If scientists rely on assumptions rather than logic, empirical confirmation, and falsification, they are no longer doing science but ideology – which is, by definition, unethical. As a recent US National Academy of Sciences report put it, “bad science is always unethical.”1 This article discusses several ways in which toxicologists can fall into ideology – bad, therefore unethical, science. In part because of the increasing expense of pollution control, some toxicologists have been reexamining pollution dose-response curves that are non-monotonic, that (...) is, curves in which the direction of some response changes with increasing or decreasing dose.2 Ethanol is a classic example of a non-monotonic dose-response curve because moderate drinking is associated with lower risks of heart disease, whereas heavy drinking is associated with higher risks.3,4 If some low-dose pollutants exhibit adaptive or “beneficial effects,”5 this might suggest re-thinking pollution regulations which presuppose linear no-threshold (LNT) dose-response curves.

The biological effects of low doses of toxic and carcinogenic chemicals are currently a matter of significant scientific controversy. This paper argues that philosophers of science can contribute to alleviating this controversy by examining it with the aid of a novel account of scientific anomaly. Specifically, analysis of contemporary research on chemical hormesis (i.e., alleged beneficial biological effects produced by low doses of substances that are harmful at higher doses) suggests that scientists may initially describe anomalous phenomena in terms of (...) multiple distinct "characterizations," each of which is compatible with current empirical evidence. By focusing attention on this feature of scientific anomalies, philosophers of science can alleviate the controversy over low-dose chemical effects in at least two ways: (1) they can pinpoint the significant ways in which particular characterizations frame the controversy, and (2) they can identify the methodological value judgments at stake in researchers' choice of characterizations.

We investigate a phenomenon which we have experienced as common when dealing with an assortment of Italian public and private institutions: people promise to exchange high-quality goods and services, but then something goes wrong and the quality delivered is lower than had been promised. While this is perceived as ‘cheating’ by outsiders, insiders seem not only to adapt to, but to rely on this outcome. They do not resent low-quality exchanges; in fact, they seem to resent high-quality ones, and are (...) inclined to put pressure on or avoid dealing with agents who deliver high quality. The equilibrium among low-quality producers relies on an unusual preference ranking which differs from that associated with the Prisoners’ Dilemma and similar games, whereby self-interested rational agents prefer to dish out low quality in exchange for high quality. While equally ‘lazy’, agents in our low-quality worlds are oddly ‘pro-social’: for the advantage of maximizing their raw self-interest, they prefer to receive low-quality goods and services, provided that they too can in exchange deliver low quality without embarrassment. They develop a set of oblique social norms to sustain their preferred equilibrium when threatened by the intrusion of high quality. We argue that high-quality collective outcomes are endangered not only by self-interested individual defectors, but by ‘cartels’ of mutually satisfied mediocrities. (shrink)
Predictions about the health risks of low level radiation combine two sorts of measures. One estimates the amount and kinds of radiation released into the environment, and the other estimates the adverse health effects. A new field called health physics integrates and applies nuclear physics to cytology to supply both these estimates. It does so by first determining the kinds of effects different types of radiation produce in biological organisms, and second, by monitoring the extent of these effects produced by (...) given levels of exposure. This essay examines the interplay between evidential constraints and external, contextual interests and values in studying the biological hazards of radiation. By analyzing the debate over linear vs. quadratic dose response models, the essay focuses on problems of developing quantitative, rather than qualitative, estimates of the risks of increased cancer incidence in an exposed population.

: In 1998, 39 pharmaceutical manufacturers sued the government of South Africa to prevent the implementation of a law designed to facilitate access to AIDS drugs at low cost.

Product quality is defined as suitability to a general purpose.

Finally, a low-quality product should be designed afresh, not by altering an existing high-quality product. (shrink)

GY, an extensively studied human hemianope, is aware of salient visual events in his cortically blind field but does not call this ''vision.'' To learn whether he has low-level conscious visual sensations or whether instead he has gained conscious knowledge about, or access to, visual information that does not produce a conscious phenomenal sensation, we attempted to image process a stimulus s presented to the impaired field so that when the transformed stimulus T(s) was presented to the normal hemifield it (...) would cause a sensation similar to that caused by s in the impaired field. While degradation of contrast, spatio-temporal filtering, contrast reversal, and addition of smear and random blobs all failed to match the response to a flashed bar sf, moving textures of low contrast were accepted to match the response to a moving contrast-defined bar, sm. Orientation and motion direction discrimination of the perceptually matched stimuli [sm and T(sm)] was closely similar. We suggest that the existence of a satisfactory match indicates that GY has phenomenal vision. (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.
Priority setting presents one of the biggest challenges policy makers in low-income countries have to deal with on a daily basis. Extreme lack of resources in these contexts introduces non-state stakeholders whose priorities may not necessarily reflect the national priorities. This raises concerns about the legitimacy of the non-state stakeholders' involvement in priority setting. To date, the meagre literature on priority setting in low-income countries has not focused on the question of the legitimacy of the non-state stakeholders, specifically, the development (...) partners. This article fills this gap in the literature. We provide an overview of some of the health sector priority setting approaches, of relevance to low-income countries, including the processes, the stakeholders and their roles, and the priority setting challenges. These factors are explored, in-depth, using the case of Uganda. The sources of legitimacy of development assistance partners' involvement in priority setting is assessed based on current literature on sources of legitimacy and legitimacy in priority setting. The article concludes that both the government and development assistance partners need to work together to foster and maintain their legitimacy through; having fair priority setting processes with wide representation of all relevant stakeholders, explicit priority setting processes and a balance of decision making powers with commitment to accountability and transparency.

The Amsterdam–ASTRON Radio Transient Facility And Analysis Centre (AARTFAAC) project aims to implement an all-sky monitor (ASM), using the low-frequency array (LOFAR) telescope. It will enable real-time, 24 × 7 monitoring for low-frequency radio transients over most of the sky locally visible to the LOFAR at time scales ranging from seconds to several days, and rapid triggering of follow-up observations with the full LOFAR on detection of potential transient candidates. These requirements pose several implementation challenges: imaging of an all-sky field (...) of view, low latencies of processing, continuous availability and autonomous operation of the ASM. The first of these has already resulted in the correlator for the ASM being the largest in the world in terms of the number of input data streams. We have carried out test observations using existing LOFAR infrastructure, in order to quantify and constrain crucial instrumental design criteria for the ASM. In this study, we present an overview of the AARTFAAC data-processing pipeline and illustrate some of the aforementioned challenges by showing all-sky images obtained from one of the test observations. These results provide quantitative estimates of the capabilities of the instrument. (shrink)
Bitton and Eyal's lengthy critique of our article on unassisted cessation was premised on several straw-man arguments. These are corrected in our reply. It also confused the key concepts of efficacy and effectiveness in assessing the impact of cessation interventions and policies in real-world settings; ignored any consideration of reach (cost, consumer acceptability and accessibility) and failed to consider that clinical cessation interventions which fail more than they succeed also may ‘harm’ smokers by reducing agency.

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)

A common view in face recognition research holds that there is a stored representation specific to each known face. It is also posited that semantic or memory-based information cannot influence low-level face processing. The two experiments reported in this article investigate the nature of this representation and the flow of face information processing. Participants had to search for a particular primed face among other faces. In Experiment 1, the search was done in a context where distractors had either a different (...) degree of fame or the same degree of fame. In Experiment 2, the target face was primed either with semantic information or without any information. Both experiments demonstrated that increasing the display set size lengthened face detection time. However, the lengthening was a function of face fame. The search context also had an effect on the slope of the famous face detection. The results are explained in terms of the idea that face representations are reconstructed and that high- and low-level information are integrated into the processing. The integration process is not a conscious one. (shrink)
Basic processes of perception should be cognitively impenetrable so that they are not prey to momentary changes of belief.

In this paper I give a Bayesian criterion for when an experiment is a test of the theory of the apparatus, rather than a test of the theory of the phenomena, and describe strategies used to ensure that tests of the theory of the phenomena are possible. I extend this framework to low dose electron microscopy which has a stochastic instrument theory and which provides an exception to a thesis by Robert Ackermann on the independence between theory and instrumentation.
The expansion of human evolutionary theory into the domain of personal and environmental determinants of mating strategies is applauded. Questions are raised about the relation between fluctuating asymmetry (FA), testosterone, and body size and their effects on male behavior and outcomes. Low FA males' short-term mating pattern is considered in the context of an evolved tendency for closer and longer human relationships.
We discuss whether low-dimensional chaos and even nonlinear processes can be traced in the electrical activity of the brain. Experimental data show that the dimensional complexity of the EEG decreases during event-related potentials associated with cognitive effort. This probably represents increased nonlinear cooperation between different neural systems during sensory information processing.
Let B be a superatomic Boolean algebra (BA). The rank of B (rk(B)), is defined to be the Cantor Bendixon rank of the Stone space of B. If a ∈ B - {0}, then the rank of a in B (rk(a)), is defined to be the rank of the Boolean algebra $B b \upharpoonright a \overset{\mathrm{def}}{=} \{b \in B: b \leq a\}$ . The rank of 0 B is defined to be -1. An element a ∈ B - {0} is (...) a generalized atom $(a \in \widehat{At}(B))$ , if the last nonzero cardinal in the cardinal sequence of B $\upharpoonright$ a is 1. Let a,b $\in\widehat{At}$ (B). We denote a ∼ b, if rk(a) = rk(b) = rk(a · b). A subset H $\subseteq \widehat{At}$ (B) is a complete set of representatives (CSR) for B, if for every a $\in \widehat{At}$ (B) there is a unique h ∈ H such that h ∼ a. Any CSR for B generates B. We say that B is canonically well-generated (CWG), if it has a CSR H such that the sublattice of B generated by H is well-founded. We say that B is well-generated, if it has a well-founded sublattice L such that L generates B. THEOREM 1. Let B be a Boolean algebra with cardinal sequence $\langle\aleph_0: i . If B is CWG, then every subalgebra of B is CWG. A superatomic Boolean algebra B is essentially low (ESL), if it has a countable ideal I such that rk(B/I) ≤ 1. Theorem 1 follows from Theorem 2.9, which is the main result of this work. For an ESL BA B we define a set F B of partial functions from a certain countably infinite set to ω (Definition 2.8). Theorem 2.9 says that if B is an ESL Boolean algebra, then the following are equivalent. (1) Every subalgebra of B is CWG; and (2) F B is bounded. THEOREM 2. If an ESL Boolean algebra is not CWG, then it has a subalgebra which is not well-generated. (shrink)
There is currently an evidentiary gap in the scholarship concerning medical tourism's impact on low- and middle-income destination countries (LMICs). This article reviews relevant evidence that exists and concludes that there are signs of correlation between medical tourism and the expansion of private, technology- intensive health care in LMICs, which has largely remained out of reach for the majority of the local patients. In light of this health care inequity between local residents and medical tourists in LMICs, we argue that (...) the presumption should not be in favor of medical tourism and that governments have a legitimate interest in seeking to regulate this industry to ensure that the net effects for their citizens is positive. Moreover, sending countries, particularly those in the developed world, have the responsibility to adopt public policies to diminish demand on the part of their citizens for medical tourism and to work with LMICs to ensure that the growth of medical tourism does not occur at the expense of the poorest of the poor.

It is shown that there exists a low2 Harrington non-splitting base-that is, a low2 computably enumerable (c.e.) degree a such that for any c.e. degrees x, y, if $0' = x \vee y$ , then either $0' = x \vee a$ or $0' = y \vee a$ . Contrary to prior expectations, the standard Harrington non-splitting construction is incompatible with the $low_{2}-ness$ requirements to be satisfied, and the proof given involves new techniques with potentially wider application.
The purpose of this paper is to elaborate on the notion of clinical medicine as a hermeneutical enterprise and to bridge the gap between the general perspectives of hermeneutics and the particularities of medical practice. The case of a patient with low back pain is analyzed. The discussion centers around the metaphor of the patient as a text and a model of five social discourses about low back pain. The problems addressed are: (1) the nature of a moral experience, (2) (...) the variety of available texts, (3) the difference between the doctor's and patient's narratives, and (4) the patient's and doctor's responsibility regarding the existential, biographical meaning of an illness. Although many problems are left unsolved, it is argued that from a philosophical point of view the notion of medicine as a hermeneutical enterprise opens up the possibility of gaining insight in the foundations of the clinical encounter.

Learning to recognize visual objects from examples requires the ability to find meaningful patterns in spaces of very high dimensionality. We present a method for dimensionality reduction which effectively biases the learning system by combining multiple constraints via the use of class labels. The use of extensive class labels steers the resulting lowdimensional representation to become invariant to those directions of variation in the input space that are irrelevant to classification; this is done merely by making class labels independent of (...) these directions. We also show that prior knowledge of the proper dimensionality of the target representation can be imposed by training a multi-layer bottleneck network. Computational experiments involving non-trivial categorization of parameterized fractal images and of human faces indicate that the low-dimensional representation extracted by our method leads to improved generalization in the learned tasks and is likely to preserve the topology of the original space.

Keynes's theory of interest is central to his broader argument. However, short?run policy, which takes the so?called normal rate of interest as given and aims at affecting the prevailing rate, must be distinguished from long?run reform, which aims at changing the normal rate. The low demand that Keynes associated with high interest was believed to be inherent in a decentralized, consumption?oriented economy. Consequently, he advocated reform in the direction of central control. Despite his ?moral and philosophical? agreement with Hayek's Road (...) to Serfdom, Keynes differed fundamentally from Hayek in terms of their contrasting perceptions of the market's shortcomings and their judgments about the government's potential for improving the economy's performance.

E-Z Reader 7 is a processing model of eye-movement control. One constraint imposed on the model is that high-level cognitive processes do not influence eye movements unless normal reading processes are disturbed. I suggest that this constraint is unnecessary, and that the model provides a sensible architecture for explaining how both low- and high-level processes influence eye movements.
In a recent article in American Scientist, a Berkeley expert quips: “Chicken Little is alive and well in America.” Never in history have health and environment-related hazards been so low, he says, while “so much effort is put into removing the last few percent of pollution or the last little bit of risk.” He thinks we have monumental battles over negligible risks, battles that are extraordinarily expensive for the industries that must pay to control pollution or to reduce risk.
Previous research has demonstrated electroencephalogram (EEG) changes in response to low-odor concentrations, resulting in near-chance detection. Such findings have been taken as evidence for olfaction without awareness. We replicated and extended previous work by examining EEG responses to water-water control, 0.0001, 0.001, 0.01, and 1 ppm isoamyl acetate (IAA) in water paired with water only. Detection was above chance (>50%) for .001 and above, and alpha decreased only to those concentrations, suggesting that EEG changes corresponded to IAA awareness. However, when (...) correct trial EEGs were compared to incorrect trial EEGs during .001 ppm, right posterior/central alpha decreased during incorrect trials and alpha decreased more globally (including frontal sites) during correct trials. These data may not reflect awareness or unawareness per se. Instead, results are discussed regarding activation of perceptual systems in the posterior region during incorrect trials and the activation of frontal action systems during a subset of correct trials.

Background The intervention reported in this paper was a follow up to an empirical study conducted in Malawi with the aim of assessing trial participants’ understanding of randomisation, double-blinding and placebo use. In the empirical study, the majority of respondents (61.1%; n= 124) obtained low scores (lower than 75%) on understanding of all three concepts under study. Based on these findings, an intervention based on a narrative which included all three concepts and their personal implications was designed. The narrative used (...) daily examples from the field of Agriculture because Malawi has an agro-based economy. Methods The intervention was tested using a sample of 36 women who had been identified as low scorers during the empirical study. The 36 low scorers were randomly assigned to control (n=18) and intervention arms ( n =18). The control arm went through a session in which they were provided with standard informed consent information for the microbicide trial. The intervention arm went through a session in which they were provided with a narrative in ChiChewa, the local language, with the assistance of a power point presentation which included pictures as well as discussions on justification and personal implications of the concepts under study. Results The findings on the efficacy of the intervention suggest that the 3 scientific concepts and their personal implications can be understood by low literacy populations using simple language and everyday local examples. The findings also suggest that the intervention positively impacted on understanding of trial procedures under study, as 13 of the 18 women in the intervention arm, obtained high scores (above 75%) during the post intervention assessment and none of the 18 in the control arm obtained a high score. Using Fischer’s exact test, it was confirmed that the effect of the intervention on understanding of the three procedures was statistically significant (p=0.0001). Conclusions Potential trial participants can be assisted to understand key clinical trial procedures, their justification and personal implications by using innovative tailored local narratives.

: This essay considers the important role attributed to education in the writings of nineteenth-century feminist Harriet Taylor Mill. Taylor Mill connected ignorance to inequality between the sexes. She called up the specter of regression into lowness and ignorance when she associated feminism with progress. As she stressed the importance of education, she constructed an 'other' to feminism, variously associated with lowness, poverty, and the primitive. She made a case for the advantages of civilization (education, enfranchisement, equality) to be opened (...) up to women. Yet Taylor Mill's position that the ignorant poor, like all humans, should be in a position of so-called "perfect equality" drifted intermittently into the view that the elevation of women to perfect equality would refine and elevate the lower classes.

Suppose that God or a demon informs you of the following future fact: despite recent cosmological evidence, the universe is indeed closed and it will have a ‘final’ instant of time; moreover, at that final moment, all 49 of the world’s Imperial Faberge eggs will be in your bedroom bureau’s sock drawer. You’re absolutely certain that this information is true. All of your other dealings with supernatural powers have demonstrated that they are a trustworthy lot.
Stanley’s insightful new book refines his earlier formulation of intellectualism. Indeed, it does a whole lot more, but leaves open some tough questions. He makes a powerful case for the view that knowing how to do something is to know, of a certain way, that one could do that thing in that way. But he says surprisingly little about what ways are, and how they might differ, depending on the kind of case. And he doesn't exclude the possibility that in (...) some cases what one knows in knowing-how is a way of doing something rather than a fact about a way of doing it. (shrink)
Jason Stanley's Know How aims to offer an attractive intellectualist analysis of knowledge how that is compositionally predicted by the best available treatments of sentences like 'Emile knows how to make his dad smile.' This paper explores one significant way in which Stanley's compositional treatment fails to generate his preferred account, and advocates a minimal solution.
As tends to be the way with philosophical positions, there are at least as many two-dimensionalisms as there are two-dimensionalists. But painting with a broad brush, there are core epistemological and metaphysical commitments which underlie the two-dimensionalist project, commitments for which I have no sympathies. A sketch of three signi?cant points of disagreement.
Jason Stanley has argued that in order to obtain the desired readings of certain sentences, such as “In most of John’s classes, he fails exactly three Frenchmen”, we must suppose that each common noun is associated with a hidden indexical that may be either bound by a higher quantifier phrase or interpreted by the context. This paper shows that the desired readings can be obtained as well by interpreting nouns as expressing relations and without supposing that nouns are associated (...) with hidden indexicals. Stanley’s theory and the present alternative are not equivalent, however. They differ over the status of sentences such as “Every student is happy and some student is not happy”. On Stanley’s theory, this sentence will be true in some contexts, while on the present alternative it will be true in no context. Considerations in favor of the present theory’s verdict on such sentences are presented. The broader question at issue is the correct way to incorporate context-relativity into formal semantics.

The latest newcomer on the epistemology scene is Subject-Sensitive Invariantism (SSI), which is the view that even though the semantics of the verb “know” is invariant, the answer to the question of whether someone knows something is sensitive to factors about that person. Factors about the context of the purported knower are relevant to whether he knows some proposition p or not. In this paper I present Jason Stanley's version of SSI, a theory Stanley calls Interest-Relative Invariantism (IRI). The (...) core epistemological claim of IRI is that knowledge is conceptually connected to practical interests. Stanley's defence of IRI is closely connected to practical reasoning, but unfortunately, I argue, IRI leads to bad practical reasoning. I furthermore show that Stanley's IRI cannot accommodate all of Stanley's five test cases for knowledge attribution, test cases that are supposed to (more or less) make or break theories of knowledge attribution. IRI also has some quite counterintuitive results and derives much of its appeal from one-sidedness of Stanley's examples. The net effect, I claim, is that IRI should be resisted. (shrink)
Doug Husak frames a worry that makes sense in the abstract, but in reality, there is not much to worry about. The thesis that intentions are irrelevant to permissibility (IIP) is a straw man. There are reasons to think that the moral significance of intentions is not properly registered in criminal law. But the moral basis for criticism is not nearly as extreme as the IIP, and the fixes are not that hard to make. Lastly, if they are not made, (...) some people may not get the punishments they deserve, and there will be some extra inequities in the criminal law as a result. But these inequities are not so great that change must be made now. The moral categories that are used may be too crude, but they are also familiar and easy to work with, and that counts for something. (shrink)
Depression is, according to a World Health Organization study, the world’s fourth worst health problem, measured by how many years of good health it causes to be lost. By 2020, it is likely to rank second, behind heart disease. Yet not nearly enough is being done to treat or prevent it.
At the end of the 1990s, Brazil was faced with a potentially explosive HIV/AIDS epidemic. Through an innovative and multifaceted campaign, and despite initial resistance from multinational pharmaceutical companies, the government of Brazil was able to negotiate price reductions for HIV medications and develop local production capacity, thereby averting a public health disaster. Using interview data and document analysis, the authors show that the exercise of corporate social responsibility can be viewed in practice as a dynamic negotiation and an interaction (...) between multiple actors. Action undertaken in terms of voluntary CSR alone may be insufficient. This finding highlights the importance of a strong role for national governments and international organizations to pressure companies to perform better. (shrink)
Using a sample of over 700 business people and students, this study tested the premise of promise-keeping as a core ethical value in the work place.The exercise consisted of in-basket planning for layoffs within an organization. Only one of the five employees within the group had been given an express commitment/promise of continued employment for a two year period. The layoffs were being considered six months after the two year promise had been made. All five employees were performing their jobs (...) adequately, and each had either personal or work attributes representing competing values that would have made it difficult to choose among them.

The current ethical structure for collaborative international health research stems largely from developed countries' standards of proper ethical practices. The result is that ethical committees in developing countries are required to adhere to standards that might impose practices that conflict with local culture and unintended interpretations of ethics, treatments, and research. This paper presents a case example of a joint international research project that successfully established inclusive ethical review processes as well as other groundwork and components necessary for the (...) conduct of human behavior research and research capacity building in the host country.

Australian women who are university graduates have fewer children than non-graduates. In most cases this appears to be the result of circumstantial pressures not preference. Long years of study fill the most fertile years of women students and new graduates need further time to establish their careers. The chance of medical infertility increases with age so, for some, this means that childbearing is not postponed but ruled out. Graduates who do make the transition from university to professional work find that (...) working hours are long and that professional occupations are now both highly demanding and insecure. Women who take time off to care for young children must depend on one insecure income (their partner’s) rather than two, and their return to work is uncertain. These difficulties of time, money and insecurity are compounded by problems in finding a suitable partner. They are magnified by the enduring tendency of women to marry up. Thus it can be more difficult for women graduates to find husbands than it is for women who are non-graduates. (shrink)
