Semantic networks were developed in cognitive science and artificial intelligence studies as graphical knowledge representation and inference tools emulating human thought processes. Formal analysis of the representation and inference capabilities of the networks modeled them as subsets of standard first-order logic (FOL), restricted in the operations allowed in order to ensure the tractability that seemed to characterize human reasoning capabilities. The graphical network representations were modeled as providing a visual language for the logic. Sub-sets of FOL targeted on knowledge representation (...) came to be called description logics, and research on these logics has focused on issues of tractability of subsets with differing representation capabilities, and on the implementation of practical inference systems achieving the best possible performance. Semantic network research has kept pace with these developments, providing visual languages for knowledge entry, editing, and presenting the results of inference, that translate unambiguously to the underlying description logics. This paper discusses the design issues for such semantic network formalisms, and illustrates them through detailed examples of significant generic knowledge structures analyzed in the literature, including determinables, contrast sets, genus/differentiae, taxonomies, faceted taxonomies, cluster concepts, family resemblances, graded concepts, frames, definitions, rules, rules with exceptions, essence and state assertions, opposites and contraries, relevance, and so on. Such examples provide important test material for any visual language formalism for logic. (shrink)

Recent years have seen a renewed interest in the philosophical study of information. In this paper a two-part analysis of information gain—objective and subjective—in the context of doxastic change is presented and discussed. Objective information gain is analyzed in terms of doxastic movement towards true belief, while subjective information gain is analyzed as an agent’s expectation value of her objective information gain for a given doxastic change. The resulting expression for subjective (...) information gain turns out to be a familiar one with well-known formal properties: the Kullback–Leibler divergence. The two notions of information are discussed and the suggested measure of subjective information gain is then compared with the widely held view that information gain equals uncertainty reduction.

Current theories propose that our sense of curiosity is determined by the learning progress or information gain that our cognitive system expects to make. However, few studies have explicitly tried to quantify subjective information gain and link it to measures of curiosity. Here, we asked people to report their curiosity about the intrinsically engaging perceptual ‘puzzles’ known as Mooney images, and to report on the strength of their aha experience upon revealing the solution image (curiosity relief). (...) We also asked our participants (279) to make a guess concerning the solution of the image, and used the distribution of these guesses to compute the crowdsourced semantic entropy (or ambiguity) of the images, as a measure of the potential for information gain. Our results confirm that curiosity and, even more so, aha experience is substantially associated with this semantic information gain measure. These findings support the expected information gain theory of curiosity and suggest that the aha experience or intrinsic reward is driven by the actual information gain. In an unannounced memory part, we also established that the often reported influence of curiosity on memory is fully mediated by the aha experience or curiosity relief. We discuss the implications of our results for the burgeoning fields of curiosity and psychoaesthetics. (shrink)

Information about the environment is captured in human biological systems on a variety of interacting levels – in distributions of genes, linguistic particulars, concepts, methods, theories, preferences, and overt behaviors. I investigate some of the basic principles which govern such a hierarchy by constructing a comparatively simple three-level selection model of bee foraging preferences and behaviors. The information-theoretic notion of ''''mutual information'''' is employed as a measure of efficiency in tracking a changing environment, and its appropriateness in (...) epistemological applications is discussed at some length. In particular, information accumulated in mid-level preference distributions exhibits suggestive properties for the purposes of naturalistic epistemology. It also appears that the novelty of scientific objects and representations and the rapidity of scientific change relative to genetic change need present no obstacle to the use of such models in explanations of scientific progress and the reliability of scientific judgement.

This article considers an asymmetric contest with incomplete information. There are two types of players: informed and uninformed. Each player has a different ability to translate effort into performance in terms of the contest success function. While one player’s type is known to both players, the other is private information and known only to the player himself. We compare the Bayesian Nash equilibrium outcome of a one-sided private information contest to the Nash equilibrium with no private (...) class='Hi'>information, in which both players know the type of the other player. We show conditions under which uncertainty increases the investment of the uninformed player and the rent dissipation of the contest, while decreasing the expected net payoff of the informed player. In addition, we consider conditions under which the informed player—before knowing his own type—prefers that the uninformed player knows his type. Moreover, we show conditions for the existence/non-existence of equilibrium in a two-stage contest in which the informed player declares his type (or does not declare) in the first stage and in the second stage the two players play according to the information available to them.

Background Obtaining informed consent in the clinical setting is an important yet challenging aspect of providing safe and collaborative care to patients. While the medical profession has defined best practices for obtaining informed consent, it is unclear whether these standards meet the expressed needs of patients, their families as well as healthcare providers. The authors sought to address this gap by comparing the responses of these three groups with a standardised informed consent paradigm. Methods Piloting a web-based ‘reverse’ simulation paradigm, (...) participants viewed a video showing a standardised doctor engaging in an informed consent discussion. The scenario depicted a simulated patient with psychotic symptoms who is prescribed an atypical antipsychotic medication. 107 participants accessed the simulation online and completed a web-based debriefing survey. Results Survey responses from patients, family members and healthcare providers indicated disparities in information retention, perception of the doctor's performance and priorities for required elements of the consent process. Conclusions To enhance existing informed consent best practices, steps should be taken to improve patient retention of critical information. Adverse events should be described in the short-term and long-term along with preventative measures, and alternative psychosocial and pharmacological treatment options should be reviewed. Information about treatment should include when the medication takes therapeutic effect and how to safely maintain the treatment. The reverse simulation design is a model that can discern gaps in clinical practice, which can be used to improve patient care. (shrink)

Gaining information can be modelled as a narrowing of epistemic space . Intuitively, becoming informed that such-and-such is the case rules out certain scenarios or would-be possibilities. Chalmers’s account of epistemic space treats it as a space of a priori possibility and so has trouble in dealing with the information which we intuitively feel can be gained from logical inference. I propose a more inclusive notion of epistemic space, based on Priest’s notion of open worlds yet which contains (...) only those epistemic scenarios which are not obviously impossible. Whether something is obvious is not always a determinate matter and so the resulting picture is of an epistemic space with fuzzy boundaries. (shrink)

This paper conducts an evaluative study on the rehabilitation of limb motor function by using a microsensor information flow gain algorithm and investigates the surface electromyography signals of the upper limb during rehabilitation training. The surface EMG signals contain a large amount of limb movement information. By analysing and processing the surface EMG signals, we can grasp the human muscle movement state and identify the human upper limb movement intention. The EMG signals were processed by the trap (...) and filter combination denoising method and wavelet denoising method, respectively, the signal-to-noise ratio was used to evaluate the noise reduction effect, and finally, the wavelet denoising method with a better noise reduction effect was selected to process all the EMG signals. After the noise is removed, the signal is extracted in the time domain and frequency domain, and the root mean square, absolute mean, median frequency in the time domain, and average power frequency in the frequency domain are selected and input to the classifier for pattern recognition. The support vector machine is used to classify the myoelectric signals and optimize the parameters in the support vector machine using the grid search method and particle swarm optimization algorithm and classify the test samples using the trained support vector machine. Compared with the classification results of the grid search optimized support vector machine, the optimized vector machine has a 7% higher recognition rate, reaching 85%. The action recognition classification method of myoelectric signals is combined with an upper limb rehabilitation training platform to verify the feasibility of using myoelectric signals for rehabilitation training. After the classifier recognizes the upper limb movements, the upper computer sends movement commands to the controller to make the rehabilitation platform move according to the recognition results, and finally, the movement execution accuracy of the rehabilitation platform reaches 80% on average.

In this study, we used a word search puzzle paradigm to investigate age differences in the rate of information gain and the cues used to make patch-departure decisions in information foraging. The likelihood of patch departure increased as the profitability of the patch decreased generally. Both younger and older adults persisted past the point of optimality as defined by the marginal value theorem, which assumes perfect knowledge of the foraging ecology. Nevertheless, there was evidence that adults were (...) rational in terms of being sensitive to the change in RG for making the patch-departure decisions. However, given the limitations in cognitive resources and knowledge about the ecology, the estimation of RG may not be accurate. Younger adults were more likely to leave the puzzle as the long-term RG incrementally decreased, whereas older adults were more likely to leave the puzzle as the local RG decreased. However, older adults with better executive control were more likely to adjust their likelihood of patch-departure decisions to the long-term change in RG. Thus, age-dependent reliance on the long-term or local change in RG to make patch-departure decisions might be due to individual differences in executive control. (shrink)

The process of obtaining informed consent in a teaching hospital in a developing country (e.g. Nigeria) is shaped by factors which, to the Western world, may be seen to be anti-autonomomous: autonomy being one of the pillars of an ideal informed consent. However, the mix of cultural bioethics and local moral obligation in the face of communal tradition ensures a mutually acceptable informed consent process. Paternalism is indeed encouraged by the patients who prefer to see the doctor as all-powerful and (...) all-knowing, and this is buttressed by the cultural practice of customary obedience to those ‘above you’: either in age or social rank. The local moral obligation reassures the patients that those in authority will always look after others placed in their care without recourse to lengthy discussions or signed documentation, while the communal traditions ensure that the designated head of a family unit has the honor and sole responsibility of assenting and consenting to an operation to be carried out on a younger, or female, member of the family. Indeed it is to only a few educated patients that the informed consent process is deemed a shield against litigation by the doctors. This paper later addresses the need for physicians to update their knowledge on the process of informed consent through the attendance of biomedical ethics courses, which should highlight socio-cultural practices that may make this process different from the Western concept, but perfectly acceptable in this setting.

Gain-of-function research involves experimentation that aims or is expected to increase the transmissibility and/or virulence of pathogens. Such research, when conducted by responsible scientists, usually aims to improve understanding of disease causing agents, their interaction with human hosts, and/or their potential to cause pandemics. The ultimate objective of such research is to better inform public health and preparedness efforts and/or development of medical countermeasures. Despite these important potential benefits, GOF research can pose risks regarding biosecurity and biosafety. In 2014 (...) the administration of US President Barack Obama called for a “pause” on funding of GOF experiments involving influenza, SARS, and MERS viruses in particular. With announcement of this pause, the US Government launched a “deliberative process” regarding risks and benefits of GOFR to inform future funding decisions—and the US National Science Advisory Board for Biosecurity was tasked with making recommendations to the US Government on this matter. As part of this deliberative process the National Institutes of Health commissioned this Ethical Analysis White Paper, requesting that it provide review and summary of ethical literature on GOFR, identification and analysis of existing ethical and decision-making frameworks relevant to the evaluation of risks and benefits of GOFR, decision-making about the conduct of GOF studies, and the development of US policy regarding GOFR, and development of an ethical and decision-making framework that may be considered by NSABB when analyzing information provided by GOFR risk-benefit assessment, and when crafting its final recommendations. The ethical and decision-making framework ultimately developed is based on the idea that there are numerous ethically relevant dimensions upon which any given case of GOFR can fare better or worse : research imperative, proportionality, minimization of risks, manageability of risks, justice, good governance, evidence, and international outlook and engagement. Rather than drawing a sharp bright line between GOFR studies that are ethically acceptable and those that are ethically unacceptable, this framework is designed to indicate where any given study would fall on an ethical spectrum—where imaginable cases of GOFR might range from those that are most ethically acceptable, at one end of the spectrum, to those that are most ethically problematic or unacceptable, at the other. The aim should be that any GOFR pursued should be as far as possible towards the former end of the spectrum. (shrink)

The process of seeking the consent of a patient to a medical procedure is, arguably, one of the most important skills a doctor, or indeed any clinician, should learn. In fact, the very idea that doctors may institute diagnostic or treatment processes of any sort without a patient's consent is utterly counter-intuitive to the modern practice of medicine. It was not always thus, and even now it can be reliably assumed that consent is still not sought and gained appropriately in (...) every clinical encounter. To say that it should be sought and gained in this manner elevates the value of consent to a high level. It can be instructive to ask oneself why such a value might be held to be the case. The answer to this question lies in the philosophical underpinning of clinical consent, which sits within a notion of personal autonomy, and respect for autonomous decision making. (shrink)

Citizen-gathered evidence (CGE) gathered by individuals organized in collectives have the potential to demonstrate environmental and social wrongdoings in court. We identify (collective) agency and resistance in how individuals and communities that have been exposed to socio-environmental stressors turn to gather CGE. We explore the modes through which people gather scientific data, produce CGE, alert authorities to environmental harm, and the methods by which data can be shared with communities, beginning with the case studies of civic environmental monitoring addressing coal (...) ash pollution in North Carolina. We analyze the case studies through a theoretical lens built on (1) the theory of civic monitoring “as resistance;” (2) the argument that CGE can embody “collective intelligence;” and (3) the concept of “crowd science” through a decentralized yet coordinated network. In the first part of the article, we introduce the case studies. Then, we illustrate our theoretical frame as applied to the analysis of the cases. We discuss the cases and in particular the CGE at issue through the prism of the frame. We demonstrate how CGE can be valuable not only for civil society and civic organizations, but also for competent authorities. In our conclusion, we identify critical junctures of our case studies, such as that of “knowledge crowdsourcing” to demand justice that triggers the government to take action and the existence of a “coordinated” yet decentralized crowd to capture the full extension of the problem. Lastly, we outline the limitations of our study, a future research agenda, and still open questions. (shrink)

Informational theories of semantic content have been recently gaining prominence in the debate on the notion of mental representation. In this paper we examine new-wave informational theories which have a special focus on cognitive science. In particular, we argue that these theories face four important difficulties: they do not fully solve the problem of error, fall prey to the wrong distality attribution problem, have serious difficulties accounting for ambiguous and redundant representations and fail to deliver a metasemantic theory of representation. (...) Furthermore, we argue that these difficulties derive from their exclusive reliance on the notion of information, so we suggest that pure informational accounts should be complemented with functional approaches.

In this piece I discuss when care providers should not contact suicidal patients’ families to get collateral information from them or hospitalize patients over their objections. I suggest that when these patients are chronically suicidal, overriding these wants may be best in the short run but increase their net risk in the longer run. I also discuss in this regard how contacted families may become overprotective and how hospitalization can be traumatic. I present an alternative approach that can increase (...) these patients’ safety over the longer run and relate three practical approaches care providers may find useful: explaining their decisions to patients, monitoring their own fear, and instilling hope.

Evidence accumulation has been the core component in recent development of perceptual and value-based decision-making theories. Most studies have focused on the evaluation of evidence between alternative options. What remains largely unknown is the process that prepares evidence: how may the decision-maker sample different sources of information sequentially, if they can only sample one source at a time? Here we propose a normative framework in prescribing how different sources of information should be sampled proactively to facilitate the decision (...) process: beliefs for different noisy sources are updated in a Bayesian manner and participants can proactively allocate resource for sampling (i.e. saccades) among different sources to maximize the information gain in such process. We show that our framework can account for human participants’ actual choice and saccade behaviors in a two-alternative value-based decision-making task. Moreover, our framework makes novel predictions about the empirical eye movement patterns. (shrink)

Many scientists regard mass and energy as the primary currency of nature. In recent years, however, the concept of information has gained importance. In this book, eminent scientists, philosophers, and theologians chart various aspects of information, from quantum information to biological and digital information, in order to understand how nature works. Beginning with a historical treatment of the topic, the book also examines physical and biological approaches to information, and the philosophical, theological, and ethical implications.

Applied a theory of information integration to decision making with probabilistic events. 10 undergraduates judged the subjective worth of duplex bets that included independent gain and lose components. The worth of each component was assumed to be the product of a subjective weight that reflected the probability of winning or losing, and the subjective worth of the money to be won or lost. The total worth of the bet was the sum of the worths of the 2 components. (...) Thus, each judgment required multiplying and adding operations. The multiplying model worked quite well in 4 experimental conditions. The adding model showed more serious discrepancies, though these were small in magnitude. The theory of functional measurement was applied to scale the subjective values of the probability and money stimuli. Subjective and objective values were nonlinearly related both for probability and for money. (shrink)

Integrated Information Theory (IIT) stands out as one of the most promising approaches to scientifically understand the emergence of consciousness. Even if it borrows from the phenomenology of consciousness to derive its axiomatic formulation, IIT does not initially adhere to any particular ontological position. However, its founder leans towards Panpsychism. More recently, Owen has studied the pros and cons of different ontologies as a metaphysical basis for IIT, defending a hylomorphic stance where en-grounding, en-forming relations gain the upper (...) hand in the causal narrative. This paper aims at (1) complementing Owen’s work by invoking additional arguments against physicalist IIT, both reductive and non-reductive; and (2) improving Owen’s characterization of non-physicalist causality through a “nested” version of hylomorphism that avoids the combination problem of Panpsychism.

Mauricio Suárez and Agnes Bolinska apply the tools of communication theory to scientific modeling in order to characterize the informational content of a scientific model. They argue that when represented as a communication channel, a model source conveys information about its target, and that such representations are therefore appropriate whenever modeling is employed for informational gain. They then extract two consequences. First, the introduction of idealizations is akin in informational terms to the introduction of noise in a signal; (...) for in an idealization we introduce ‘extraneous’ elements into the model that have no correlate in the target. Second, abstraction in a model is informationally equivalent to equivocation in the signal; for in an abstraction we “neglect” in the model certain features that obtain in the target. They conclude that it becomes possible in principle to quantify idealization and abstraction in informative models, although precise absolute quantification will be difficult to achieve in practice.

The practice of obtaining informed consent has its history in, and gains its meaning from, medicine and biomedical research. Discussions of disclosure and justified nondisclosure have played a significant role throughout the history of medical ethics, but the term “informed consent” emerged only in the 1950s. Serious discussion of the meaning and ethics of informed consent began in medicine, research, law, and philosophy only around 1972.

In lieu of an abstract, here is a brief excerpt of the content:Gaining a Heart But Missing MyselfLeilani R. GrahamI gathered it in my hands as it fell from my hair-brush, too saturated to hold anymore. It felt as if I were inside a movie and waiting for someone to yell “Cut!” but no call came. It continued to fall, feather-like onto the ground, individual strands glinting in the light of the bathroom window. My hair, nearly all of it, was (...) gone.Between the time of my heart transplant and the moment my hair began to fall out, I arguably had suffered enough. Transplant brought four open-heart surgeries, ten days on ECMO, an intra-aortic balloon pump, delirium, necrotizing pneumonia, and so much muscular atrophy that I had to re-learn how to walk. CPR, broken ribs, and the scar of a tricuspid clip from a botched biopsy: it was not the miracle I was hoping for.The internal trauma had certainly taken its toll. I no longer knew how I really felt, thanks to copious pain meds that altered my mind and body. Each limb was foreign as I re-acclimated to how one grabs hold of a cup, signs their name, touches their legs. Externally, I was a mess: covered in deep purple bruises across my torso from the diabetes treatments, dead skin pooling in unwashed pores, my ankles swollen and indiscernible from my legs. But lacking a good mirror (or the desire to find one), I still felt like “myself” during my forty-five day hospital stay. I could feel my cheekbones protruding from thinning skin, saw through unfocused eyes from the tempestuous blood sugars, and my hair sat in a rat’s nest atop my head; but I was still me.Arriving home, I felt like a newborn being brought into the real world for the first time. I needed help with everything—showers, sitting up, putting on shoes, even going to the bathroom. At age twenty-four, I felt I had regressed to the point of no return as I relied on others to do the simplest tasks. In addition, I was quarantined inside for three months, due to the risk of obtaining a fungal infection from the outside. Caged, and alone in my body, I a trapped and wounded tiger: angry, hurting, and scared. [End Page 109]When I had been prepared for transplant—and I use “prepared” loosely because the information packet I was handed was insulting at best—I knew to expect the scars. I had no issue with that, having been cut open at my throat and chest for previous surgeries. I knew to expect a 12-inch line from neck to navel: the most evident sign I would now carry that I was disabled.What I did not expect were the bullet holes— the sealed entrances of thick chest tubes that now dotted my lower torso. I did not anticipate the bruises on my arms and groin from arterial pokes. I felt violated as if I had walked into some kind of abduction and was rolled out, beaten, bruised, and, worst, touched.But it wasn’t the physical trauma that hurt the most. It was that no one seemed surprised.Immediately after transplant, the team’s focus is purely on survival. Survive the 30 days post-surgery. Survive the year. Metrics, uncomfortably tied to transplant center success statistics, funding, and clout have little to do with the patients themselves. What did I care to only survive a year? I wanted years. I wanted decades. It felt I wanted more than anyone was willing to pay attention to.The conversation was narrowed to high-risk issues: infection, rejection, or other life-threatening conditions. While this makes sense on a clinical level, what constitutes a major event for a clinician may not be of the same emotional value to the patient. In my case, I was less occupied by how the steroids were working and more obsessed with their side effects, such as how much weight I was rapidly gaining. I walked into the clinic one day with the beginnings of stretch marks and a week later had claw-like ripples down my sides. My mood swings were explosive... (shrink)

Objectives: To investigate the quality of consent gained for the use in research of tissue that is surplus after surgery. To compare the use of two consent forms: a simple locally introduced form and a more complex centrally instigated form. To discuss the attitudes of patients towards the use of their surplus tissue in research.Design: Data were collected through interviews and analysed with a combination of quantitative and qualitative analytical techniques.Participants and setting: Patients of the breast care unit at a (...) teaching hospital were interviewed at home or in a quiet room at the hospital.Results: 57 people were interviewed out of 81 approached, between October 2003 and March 2004. Most participants had a poor level of knowledge about the consent they had given, but reported being happy about having given it. The patients who had signed the locally introduced form had considerably more knowledge than those who had signed the centrally instigated form . Participants considered being well informed to be less important than believing that their opinions were valued and respected.Conclusions: The findings suggest that traditional models of informed consent are not universally applicable and, in this case, seem to overstate what people wish to know. The simple consent form achieved a better quality of informed consent and provided a better model of practice than the complex form, and it seemed that a focused approach to consent seeking is more effective and acceptable than more complex approaches.

In Campbell v MGN Ltd [2004] UKHL 22, [2004] 2 AC 457 the House of Lords approved of protecting privacy interests through incrementally developing the existing action for breach of confidence. Lord Hoffmann suggested that this modified cause of action, instead of being based upon the duty of good faith, focuses upon the protection of human autonomy and dignity. This article explores how this change in underlying values affects the availability of gain-based remedies, where breach of confidence is relied (...) upon against the wrongful publication of private information. An account of profits is generally available where a defendant profited from disclosing confidential information in breach of a pre-existing relationship of confidence. It can also be awarded for certain breaches of contractual non-disclosure agreements and to protect proprietary interests. This article argues that these existing rationales for an account of profits can, where they apply in a particular case, also support gain-based relief in a privacy context. The article then considers that the particular nature and vulnerability of privacy make it necessary to allow gain-based relief in circumstances beyond these established categories. In order to provide effective deterrence and protection against commercially motivated infringements, in particular by the media, gain-based remedies should also be available where the privacy invasion is deliberate and a particularly outrageous infringement of the claimant's rights.

Luciano Floridi presents a book that will set the agenda for the philosophy of information. PI is the philosophical field concerned with the critical investigation of the conceptual nature and basic principles of information, including its dynamics, utilisation, and sciences, and the elaboration and application of information-theoretic and computational methodologies to philosophical problems. This book lays down, for the first time, the conceptual foundations for this new area of research. It does so systematically, by pursuing three goals. (...) Its metatheoretical goal is to describe what the philosophy of information is, its problems, approaches, and methods. Its introductory goal is to help the reader to gain a better grasp of the complex and multifarious nature of the various concepts and phenomena related to information. Its analytic goal is to answer several key theoretical questions of great philosophical interest, arising from the investigation of semantic information. (shrink)

ABSTRACT:This article outlines the policy context for teachers’ learning and continuing professional development in Scotland and considers this in relation to the perspectives of key informants gained through interview.

Current policy and the associated structural arrangements are viewed as broadly positive, but interviewees express concerns that an unintended emphasis on contractual arrangements might inhibit the more (...) transformative elements of professional learning.

In the field of mathematics education, one of the main questions remaining under debate is whether students’ development of mathematical reasoning and problem-solving is aided more by solving tasks with given instructions or by solving them without instructions. It has been argued, that providing little or no instruction for a mathematical task generates a mathematical struggle, which can facilitate learning. This view in contrast, tasks in which routine procedures can be applied can lead to mechanical repetition with little or no (...) conceptual understanding. This study contrasts Creative Mathematical Reasoning (CMR), in which students must construct the mathematical method, with Algorithmic Reasoning (AR), in which predetermined methods and procedures on how to solve the task are given. Moreover, measures of fluid intelligence and working memory capacity are included in the analyses alongside the students’ math tracks. The results show that practicing with CMR tasks was superior to practicing with AR tasks in terms of students’ performance onpracticed test tasksandtransfer test tasks. Cognitive proficiency was shown to have an effect on students’ learning for both CMR and AR learning conditions. However, math tracks (advanced versus a more basic level) showed no significant effect. It is argued that going beyond step-by-step textbook solutions is essential and that students need to be presented with mathematical activities involving a struggle. In the CMR approach, students must focus on the relevant information in order to solve the task, and the characteristics of CMR tasks can guide students to the structural features that are critical for aiding comprehension.

This paper recognizes the complexity of the debate on informed consent and discusses the importance of the ongoing process of consent for people affected by Huntington's disease (HD). Although written information may not be the most appropriate form of obtaining informed consent in qualitative research, it remains an important part of the ethical approval process for health research in the UK. This paper draws on a study in which the information sheet and consent form were specifically designed to (...) help obtain consent from people who may be impaired by the cognitive and physical effects of HD. The forms were developed by drawing on expert opinion and relevant literature and fall in line with recommendations from the Mental Capacity Act 2005 to encourage people to make their own decisions. The paper describes the feasibility of a method for obtaining consent as an ongoing process with patients affected by HD using information sheets and consent forms specifically designed for people with potential cognitive and/or physical impairments. In conclusion, this paper adds a pragmatic approach to the debate on informed consent by describing the development of a written information sheet and consent form being used in a current social research study. Particular emphasis is placed on the importance of written information being adapted according to the needs of potential participants. (shrink)

"Does torture work?" is a factual rather than ethical or legal question. But legal and ethical discussions of torture should be informed by knowledge of the answer to the factual question of the reliability of torture as an interrogation technique. The question as to whether torture works should be asked before that of its legal admissibility—if it is not useful to interrogators, there is no point considering its legality in court.

Privacy concerns involving data mining are examined in terms of four questions: What exactly is data mining? How does data mining raise concerns for personal privacy? How do privacy concerns raised by data mining differ from those concerns introduced by traditional information-retrieval techniques in computer databases? How do privacy concerns raised by mining personal data from the Internet differ from those concerns introduced by mining such data from data warehouses? It is argued that the practice of using data-mining techniques, (...) whether on the Internet or in data warehouses, to gain information about persons raises privacy concerns that go beyond concerns introduced in traditional information-retrieval techniques in computer databases and are not covered by present data-protection guidelines and privacy laws.

In 1972,Ernst Ulrich and Christine von Weizs ¨acker introduced the concept of pragmatic information with three desiderata:(i) Pragmatic information should assess the impact of a message upon its receiver;(ii)Pragmatic information should vanish in the limits of complete (non-interpretable)'novelty 'and complete 'confirmation';(iii)Pragmatic information should exhibit non-classical properties since novelty and confirmation behave similarly to Fourier pairs of complementary operators in quantum mechanics. It will be shown how these three desiderata can be naturally fulfilled within the framework of (...) Gardenfors' dynamic semantics of Bayesian belief models.(i)The meaning of a message is its impact upon the epistemic states of a cognitive agent. A pragmatic information measure can then be quanti .ed by the average information gain for the transition from a prior to a posterior state.(ii)Total novelty can be represented by the identical proposition, total con- .rmation by the logical consequence of propositions. In both cases, pragmatic information vanishes.(iii)For operators that are neither idempotent nor commuting, novelty and confirmation relative to a message sequence can be defined within Gardenfors' theory of belief revisions.The proposed approach is consistent with measures of relevance derived from statistical decision theory and it contains Bar-Hillel 's and Carnap's theory of semantic information as a special case.

Gardenfors' dynamic semantics of Bayesian belief models.The meaning of a message is its impact upon the epistemic states of a cognitive agent. A pragmatic information measure can then be quanti .ed by the average information gain for the transition from a prior to a posterior state.Total novelty can be represented by the identical proposition, total con- .rmation by the logical consequence of propositions. In both cases, pragmatic information vanishes.For operators that are neither idempotent nor commuting, novelty and confirmation relative to a message sequence can be defined within Gardenfors' theory of belief revisions.The proposed approach is consistent with measures of relevance derived from statistical decision theory and it contains Bar-Hillel 's and Carnap's theory of semantic information as a special case.

There is a critique of capitalist market economy that consists in claiming not only that capitalist social relations are uncaring and alienating, nor only exploitative of the working class, but that the process of capitalist economy as a whole is a way of living, today globalized, that has gotten out of hand. Its essential nature is unmasked as a senseless circular movement that, besides ruthlessly exploiting natural resources, demeans human being itself and alienates it from the historical alternative of a (...) purportedly authentic mode of human being rooted in collective, solidaric subjectivity. The present article offers an alternative hermeneutic cast for understanding capitalism as the gainful game that can serve as philosophical orientation in fighting for a free and fair social interplay in which the powers and abilities of free individuals are appropriately and reciprocally estimated and esteemed. This requires, first and foremost, seeing through the fetishisms inherent in the valorization of reified value that the mature Marx identified in his critiques of political economy as the essential nature of capitalism. Such critical insight is necessary for orientation also in today’s predicament of the ever more encroaching and ensnaring cyberworld. (shrink)

The key assumption behind evolutionary epistemology is that animals are active learners or ‘knowers’. In the present study, I updated the concept of natural learning, developed by Henry Plotkin and John Odling-Smee, by expanding it from the animal-only territory to the biosphere-as-a-whole territory. In the new interpretation of natural learning the concept of biological information, guided by Peter Corning’s concept of “control information”, becomes the ‘glue’ holding the organism–environment interactions together. The control information guides biological systems, from (...) bacteria to ecosystems, in the process of natural learning executed by the universal algorithm. This algorithm, summarized by the acronym IGPT (information-gain-process-translate) incorporates natural cognitive methods including sensing/perception, memory, communication, and decision-making. Finally, the biosphere becomes the distributed network of communicative interactions between biological systems termed the interactome. The concept of interactome is based on Gregory Bateson’s natural epistemology known as the “ecology of mind”. Mimicking Bateson’s approach, the interactome may also be designated “physiology of mind”—the principle behind regulating the biosphere homeostasis. (shrink)

Ordinary common sense suggests that we have just one set of shape concepts that we apply indifferently on the bases of sight and touch. Yet we understand the shape concepts, we know what shape properties are, only because we have experience of shapes. And phenomenal experience of shape in vision and phenomenal experience of shape in touch seem to be quite different. So how can the shape concepts we grasp and use on the basis of vision be the same as (...) the shape concepts we grasp and use on the basis of touch? I think this is the intuitive puzzle that underlies the question sent by the Dublin lawyer Molyneux to John Locke. This concerns a man born blind, who learns by the use of his touch to discriminate cubes from spheres. Suppose him now to gain the use of his sight. And suppose him to be presented with a cube and a sphere, of nighly the same bigness. Quaere, will he be able to tell, by the use of his vision alone, which is the sphere, and which the cube? (Locke 1975, II/ix/8.). (shrink)
