Information changes as it is passed from person to person, with this process of cultural transmission allowing the minds of individuals to shape the information that they transmit. We present mathematical models of cultural transmission which predict that the amount of information passed from person to person should affect the rate at which that information changes. We tested this prediction using a function-learning task, in which people learn a functional relationship between two variables by observing (...) the values of those variables. We varied the total number of observations and the number of those observations that take unique values. We found an effect of the number of observations, with functions transmitted using fewer observations changing form more quickly. We did not find an effect of the number of unique observations, suggesting that noise in perception or memory may have affected learning. (shrink)

Information is a sequence of signals arranged in accordance with a certain method. In the practice of social language communication, this sequence of signals should also have meaning.

The relevance of smart speakers is steadily increasing, allowing users perform several daily tasks. From a commercial perspective, smart speakers also provide recommendations of products and services that may influence the consumer decision-making process. However, previous studies have mainly focused on the adoption of smart speakers, but there is a lack of proper guidelines that help design the way these devices should offer their consumption recommendations. Based on a stimulus-organism-response approach, we analyze how two features of smart speakers' recommendations influence (...) on the effectiveness of such recommendations through its impact on user engagement and attitude. Data was collected from a sample of undergrad students in Spain using an experiment design that focused on a restaurant recommendation, and analyzed using partial least squares. On the one hand, our results suggests that gender congruence generates user engagement with the smart speaker. On the other hand, message length is positively related to attitudes towards the restaurant, at a declining rate. In addition, while better attitudes lead to higher visiting intentions, the influence of engagement on visiting intentions is partially mediated via attitudes. Thus, our findings contribute to understand the antecedents of users' engagement with smart speakers, as well as its impact on the customers' willingness to follow smart speakers' recommendations, constituting a base to analyze the impact of artificial intelligence solutions aimed to smooth the transitions of a customer through the stages of purchase process.

The notion of the value of information is discussed. The value one attributes to information is determined by the result of its reception by an open nonequilibrium system. Qualitative reasoning shows that the concept of value of information makes sense only in nonequilibrium situations, and is directly connected with the nonredundancy of information. In biology it is the value and not the amount of information that is important. The value of information is especially (...) high if there are instabilities in the system; these are connected with the notions of purpose and of freedom of will. The notion of selective value, introduced by Eigen in the theory of the prebiological evolution of macromolecules, is discussed. The amount of information in various codons is calculated and the conventional definition of its value is given based on the determination of the danger of the replacement of one amino acid by another with a different value of hydrophobicity. It is shown that the relative probability of transversion is considerably lower than that of transition. As most nonsense mutations are transversions, the genetic code provides decreased probability for the most dangerous mutations. It is shown that the information of the codonUGG(Trp) is highest in both amount and value. (shrink)

Sleep strengthens memories by repeatedly reactivating associated neuron ensembles. Our studies show that although long-term memory for a medium number of word-pairs benefits from sleep, a large number does not. This suggests an upper limit to the amount of information that has access to sleep-dependent declarative memory consolidation, which is possibly linked to the availability of reactivation opportunities. Due to competing processes of global forgetting that are active during sleep, we hypothesized that even larger amounts of information (...) would enhance the proportion of information that is actively forgotten during sleep. In the present study, we aimed to induce such forgetting by challenging the sleeping brain with vast amounts of to be remembered information. For this, 78 participants learned a very large number of 640 word-pairs interspersed with periods of quiet awake rest over the course of an entire day and then either slept or stayed awake during the night. Recall was tested after another night of regular sleep. Results revealed comparable retention rates between the sleep and wake groups. Although this null-effect can be reconciled with the concept of limited capacities available for sleep-dependent consolidation, it contradicts our hypothesis that sleep would increase forgetting compared to the wake group. Additional exploratory analyses relying on equivalence testing and Bayesian statistics reveal that there is evidence against sleep having a detrimental effect on the retention of declarative memory at high information loads. We argue that forgetting occurs in both wake and sleep states through different mechanisms, i.e., through increased interference and through global synaptic downscaling, respectively. Both of these processes might scale similarly with information load. (shrink)

There has been extensive discussion in research ethics literature surrounding the appropriate form of informed consent for biobanking, whether with adapted content, or adapted forms such as broad or tiered consent. These discussions presuppose that it is possible to disclose adequate information at the outset to facilitate an informed choice to donate to a biobank. I will argue that informed consent cannot be achieved because in the biobanking context, we are either consenting to an enterprise that is not research (...) or to future research. Nor is the solution to abandon the idea that informed consent ethically requires the disclosure of a certain minimal amount of information to make an informed choice by misleadingly identifying broad, blanket or even tiered consent as forms of ‘informed’ consent. Rather, we should abandon the idea that informed consent for research can be adapted to the type of endeavor that biobanking is, and understand the goal as to develop alternatives not as alternative forms of informed consent, but rather alternatives to informed consent.

What does it mean for an agent faced with choice under uncertainty to “know” something? While a variety of mathematical methods are available to construct formal models to answer this question, the combination of different approaches may lead to unsettling paradoxes. I propose a unified theory that eliminates such inconsistencies by relying on a sharp conceptual distinction between information the decision-maker observes and how much of that information she can cognitively process. The resulting model allows for natural decision-theoretic (...) characterizations of comparing different amounts of information. (shrink)

This experiment investigated the use of positive and negative hypothesis and target tests by groups in an adaptation of the 2-4-6 Wason task. The experimental variables were range of rule (small vs large), amount of evidence (low vs high), and trial block (1 vs 2). The results were in accordance with Klayman and Ha's (1987) analysis of base rate probabilities of falsification and with additional theoretical considerations. Base rate probabilities were more descriptive of participants' behaviour in target than in (...) hypothesis tests, under low than under high amount of evidence, and at the beginning of the process than at its end. The percentage of positive tests was higher under small than large range of rule. More falsifications than verifications resulted from hypothesis tests than would be expected by a random process. When evidence is richly available, the relative importance of falsification seems to decrease. An analysis of the group compositions before and after group discussion by the PCD model (Crott, Werner, & Hoffmann, 1996) revealed that the normative weight was approximately twice as large as the informational. Groups produced fewer false answers than their members individually. (shrink)

In this paper, I discuss how information theory has been used in the study of animal communication, as well as how these uses are justified. Biologists justify their use of Shannon’s information measures by the work they do in allowing for comparisons between different organisms and because they measure a quantity that is purported to be important for natural selection. I argue that there are problems with both sorts of justification. To make these difficulties clear, I focus on (...) the use of Shannon’s information measures to quantify the amount of information transmitted by the fire ant’s odor trail and the honeybee’s waggle dance. Both of these systems are relatively simple and well understood, and the application of Shannon’s information measure to these systems initially seemed very promising and relatively straightforward. They are therefore particularly suitable for revealing the benefits and difficulties of applying Shannon’s information measures to biological systems in general, and animal communication systems in particular.

Proposal Information: In this paper it is argued that although Spinoza, unlike other great philosophers of the Enlightenment era, never actually wrote a philosophy of education as such, he did – in his Ethics – write a philosophy of self-improvement that is deeply educational at heart. When looked at against the background of his overall metaphysical system, the educational account that emerges is one that is highly curious and may even, to some extent at least, come across as counter-intuitive (...) in a contemporary setting. This is so because it grounds the greater social and political endeavors of humanity in the individual’s striving for an ever-increasing power of acting. Hence, education, for Spinoza, is a decidedly individualistic affair, but then again, so is the making of society. Since, for Spinoza, every instance of knowledge bears the unique mark of the individual body that expresses it, one might conclude that at the foundation of every social structure is an encounter between concrete bodies; each expressing a particular perspective from where to grasp the world. I would argue, based on this, that one of Spinoza’s main contributions to educational theory is his grounding of larger social endeavors in the striving of the individual. Hinged on the striving to be more rational, as dictated by the doctrine of the conatus, education appears to offer a way of grounding the structure of the human social world in the same principles as those guiding the individual. Spinoza’s doctrine of the imitation of affects thereby offers a way of linking the egoistic striving for power on behalf of the individual with the educational goal of building a sustainable society. It does so as it conditions self-improvement by the human characteristic to imitate what others desire. By being surrounded with people who desire to be more rational, one can utilize this desire for the good and become strengthened in one’s own striving for increasing one’s degree of existence. Consequently, the teaching situation is geared for guiding students towards a more rational life, at the same time as it is geared for the self-improvement of the teacher. This aspect of self-improvement is, ultimately, what will motivate the teacher in striving to enhance the lives of his or her students in the first place. Being unable to self-improve in isolation, the doctrine of the imitation of affects dictates that the rational person will be moved toward a life of generosity, not primarily for altruistic reasons, but out of a desire to become more rational and thus to gain in his or her own power of acting. The question that follows from this, of course, is how does one go about when inculcating a desire to be more rational in one’s students?Education, from a Spinozistic point of view, is ultimately about the cultivation of the potential that lies dormant in each individual, so that a person may live a happier life as a result of understanding, more adequately, their place in the natural world. The challenge, then, becomes one of overcoming the many obstacles that prevent a person from developing their potential. Pedagogy, from this point of view, may be understood in terms of the art of offering the right amount of resistance. This notion is based on the assumption that if a student encounters no resistance – or too much resistance – his or her potential remains just that – a potential. In order to develop this potential the student needs to overcome certain barriers. With regards to this, the role of the teacher may be conceived in terms of the one balancing the amount of resistance so that the student is properly challenged but at the same time not overwhelmed. Methodology or Methods/ Research Instruments or Sources Used: The paper makes for an attempt to outline a Spinozistic philosophy of education based on readings of Spinoza’s texts – primarily the Ethics – and some of the relevant secondary literature such as Della Rocca’s influential reading of Spinoza. As such it is a philosophical inquiry seeking to interconnect some key aspects of Spinoza’s philosophy with some of the major issues of education. Methodologically, this paper argues, in line with Melamed, that rather than turning to the history of philosophy in order to identify ‘precursors to [our] own views’, so as to validate what we already believe we know, it is more fruitful to turn to past philosophers in order to ‘challenge our most basic beliefs and intuitions by studying texts that are both well-argued and strongly opposed to our commonsense’. Accordingly, turning to Spinoza marks an attempt to revisit and reconceptualize some key aspects of educational thought. Conclusions, Expected Outcomes or Findings: A conclusion of this paper is that a Spinozistic philosophy of education would need to focus on resolving the tension between Spinoza’s egoism and education as a social project. To this end it identifies Spinoza’s doctrine of the imitation of affects as a possible link between the individual’s striving for power and the collective agenda of improving human well-being at large. It is also suggested that, in aspiring to inculcate a desire to be more rational in his or her students, the challenge for the Spinozistic teacher is to prompt the students to aspire to reach beyond the temporary satisfactions of the passions so as to acquire a more enduring sense of satisfaction and so that their well-being is more fully under their own command rather than under the command of various external influences. This, in turn, is connected with the notion of resistance in the sense that in experiencing the volatility of fortune – and thereby understanding the instability of relying on one’s passions – a person would appear to be more inclined to strive for a more enduring sense of happiness, even if this would mean giving up on some of the temporary pleasures that one has grown accustomed to. The resistance, then, may be conceived in terms of the overcoming of temporary pleasures that stand in the way of the developing of one’s potential. In this scenario the role of the teacher may be understood in terms of someone offering a well-balanced amount of resistance. This means that to accommodate one’s students – in the sense that one approaches them in terms of prospective customers, aspiring to satisfy their demands – is inimical to education insofar as the wants and desires of students are, generally speaking, caused by passive affects rather than their rational wills.

Many accounts of informed consent in medical ethics claim that it is valuable because it supports individual autonomy. Unfortunately there are many distinct conceptions of individual autonomy, and their ethical importance varies. A better reason for taking informed consent seriously is that it provides assurance that patients and others are neither deceived nor coerced. Present debates about the relative importance of generic and specific consent do not address this issue squarely. Consent is a propositional attitude, so intransitive: complete, wholly specific (...) consent is an illusion. Since the point of consent procedures is to limit deception and coercion, they should be designed to give patients and others control over the amount of information they receive and opportunity to rescind consent already given.

In a sample of 615 Belgians a model for fair trade buying behaviour was developed. The impact of fair trade knowledge, general attitudes towards fair trade, attitudes towards fair trade products, and the perception of the quality and quantity of fair trade information on the reported amount of money spent on fair trade products were assessed. Fair trade knowledge, overall concern and scepticism towards fair trade, and the perception of the perceived quantity and quality of fair trade (...) class='Hi'>information, influence buying behaviour directly and indirectly through product attitudes. Interest in fair trade products, price acceptability and product liking have a significant impact on fair trade buying behaviour. Product interest is the most important variable influencing buying behaviour. Implications for the campaigns of governments and for the marketing strategy of fair trade organisations are offered.

In recent years, scholars have attempted to understand the role of information in policymaking by developing several models of information utilization and have tested them empirically, at both national and state levels. This paper has called into question past studies as they relate to describing and explaining use of information. This paper tests an integrated model of information utilization that contains four sets of primary variables: decision makers’ environments (i.e., nature of policy issues), organization, individual characteristics, (...) and characteristics of information. Based on the conceptual framework, a path model is built and tested against data about knowledge utilization and policy change in two areas of mental health policy (i.e., service and financing). The findings of the study have demonstrated that decision makers’ behavior does not conform to the assumptions put forward by either the organizational interest (e.g., information source or content of information) or the communications perspective (e.g., decision makers’ attitudes toward social science research). Instead, we have shown that information utilization is affected directly and indirectly by a variety of factors and their linkage, and not dominated by one set of factors that is defined by a singe perspective. The most important paths in the model are those between factors associated with information (e.g., the amount of information received or information source) and the use of information. Interestingly, these factors also play the role of major intervening mechanisms for linking other factors to decision makers’ use of information. More importantly, the general pattern of the findings indicates that policy areas make a difference in the process of information utilization. (shrink)

We are reviewing and summarizing evidence for the processes of acquisition of information outside of conscious awareness (processing information about covariations, nonconscious indirect and interactive inferences, self-perpetuation of procedural knowledge). A considerable amount of data indicates that as compared to consciously controlled cognition, the nonconscious information-acquisition processes are not only much faster but also structurally more sophisticated in the sense that they are capable of efficient processing of multidimensional and interactive relations between variables. Those mechanisms of (...) nonconscious acquisition of information provide a major channel for the development of procedural knowledge which is indispensable for such important aspects of cognitive functioning as encoding and interpretation of stimuli and the triggering emotional reactions.

Obtaining a sufficient amount of measurable and reliable results of student surveys has always posed a challenge for university teams tasked with the provision of the quality of education. This is especially visible at faculties where education is based on the classic classroom-based model, which then transfers to clinical units, hospital wards, and specialist laboratories. The highly unpredictable pandemic situation caused by the SARS-CoV-2 virus raises the bar for the evaluation of didactics. Fortunately, the continuous technological progress in the (...) area of Artificial Intelligence makes it possible to design the implementation of tools that would improve the position of systems for the management of courses of studies. The evaluation survey for didactic classes, as one of the last output data obtained during the process, may finally become a fully recognized source of information about the conducted classes and the teachers themselves. On the other hand, it may become a tool for those surveyed to influence the quality of classes, express their opinion, present suggestions and propositions generally pertaining to changes in the process of education. New information technologies not only make it possible to improve the effectiveness of reaching the recipients, but also provide completely new, very reliable methods of acquisition of credible behaviour, used as integration data in solutions based on machine communication. Using Artificial Intelligence coupled with data may make it possible to use intelligent communication for effective management of the process of surveying – a solution that has so far been used in business, in the form of the so-called bots. As a result, this would lead to an ongoing, fully quantitative and qualitative, assessment of classes. (shrink)

As policy makers place great hope in health information technology as a means to lower costs and achieve improvements in health care quality, safety, and efficiency, organizations at the forefront of building health information exchange networks attempt to weave the concept and function of informed consent into an evolving information-driven health care system. The vast amount of information that will become available to both health professionals and patients in the new HIT-driven environment can reasonably be (...) expected to affect the relationship between them in many ways, particularly in the area of informed consent. During this early stage of HIT adoption, it is critical that we engage in discussions regarding informed consent’s proper role in a heretofore unknown health care environment — one in which electronic information sharing holds primary importance. The central and largely unexamined question of whether and how the legal and ethical underpinnings of informed consent will fit into the context of HITenabled treatment is critical to both public policy and clinical practice.

This study empirically examines the association between certain director characteristics and the extent of voluntary audit committee disclosure in annual reports. Results suggest that Singapore's publicly traded firms are more likely to voluntarily disclose audit committee related information as: the number of board members increases; different individuals occupy the roles of CEO and board chairperson; and the proportion of independent directors serving on the board increases. Findings, however, fail to show any association between the amount of voluntary audit (...) committee disclosure and the percentage of executive directors' ownership. Documented findings are of interest and benefit to various parties including regulators, corporate governance reformists, and corporate management. For instance, findings imply that a positive by-product of implementing major corporate governance reforms currently championed by corporate governance reformists will be an increase in audit committee disclosures. As a result, there will be less pressure on regulators to develop, introduce, and enforce mandatory audit committee disclosures that may be potentially intrusive to a firm's management. (shrink)

Background: According to the Declaration of Helsinki, patients who take part in a clinical trial must be adequately informed about the trial's aims, methods, expected benefits, and potential risks. The declaration does not, however, elaborate on what “adequately informed” might amount to, in practice. Medical researchers and Local Research Ethics Committees attempt to ensure that the information which potential participants are given is pitched at an appropriate level, but few studies have considered whether the patients who take part (...) in such trials feel they have been given adequate information, or whether they feel able to understand that information.Objectives: To explore trial participants' views on the amount of information provided, and of their own understanding of that information.Design: Structured interviews of patients participating in clinical trials for the treatment of chronic medical condition.Findings: Patients generally felt they were given an appropriate amount of information, and that they were able to understand all or most of it. They felt they were given adequate time to ask questions before agreeing to take part. In comparison with treatment given outwith the research setting, patients generally felt they received more information when participating in a clinical trial.Conclusions: Researchers sometimes complain that patients are given too much information during clinical trials, and have limited understanding of that information. The present study shows that this perception is not necessarily shared by patients. More research is needed in this area, particularly to gauge whether patient understanding is indeed accurate.

Background: Biomedical research nowadays is increasingly carried out in multinational and multicenter settings. Due to disparate national regulations on various ethical aspects, such as informed consent, there is the risk of ethical compromises when involving human subjects in research. Although the Declaration of Helsinki is the point of reference for ethical conduct of research on humans, national normative requirements may diverge from its provisions. The aim of this research is to examine requirements on informed consent in biomedical research in Germany, (...) Poland, and Russia to determine how each national regulatory framework relates to the provisions of the Declaration of Helsinki. Methods: For this analysis, we conducted a search of the legal databases “Gesetze im Internet” for Germany, “Internetowy System Aktow Prawnych” for Poland, and “ГAPAHT – Garant” for Russia. The search was complemented by a review of secondary literature contained in the databases Google Scholar, PubMed, Polish National Library, and eLibrary ru. We have identified 21 normative regulations containing provisions on informed consent in clinical research in all three countries. The content of these documents was systematically categorized and analyzed. Results: The normative framework in all three countries shows a strong commitment towards the core ethical principles of research envisaged in the Declaration of Helsinki. Nevertheless, provisions on informed consent vary between these three countries. The differences range from the method and language in which information should be provided, through the amount of information required to be disclosed, to the form of documenting consent or withdrawal. In the case of research on vulnerable groups, these differences are particularly visible. Conclusions: The identified differences can negatively impact the ethical conduct of international clinical studies. Attention needs to be paid that flexibilities within national regulations are not misused to undermine the protection of research subjects. Achieving global or regional legislative harmonization might prove impossible. Such lack of legal consensus reinforces the significance of the international ethical agreements. (shrink)

This paper seeks to determine the intuitive meaning of the concept of information by indicating its essential (definitional) features and relations with other concepts, such as that of knowledge. The term “information” – as with many other concepts, such as “process”, “force”, “energy” and “matter” – has a certain established meaning in natural languages, which allows it to be used, in science as well as in everyday life, without our possessing any somewhat stricter definition of it. The basic (...) aim here is thus to explicate what it amounts to in the context of its intuitive meaning as encountered in natural languages, what the subject of cognition implicitly presumes when using the term, and to which ontological situations it can be applied. I demonstrate that the essential features of the notion of information include the presence of a material medium, its transformation, the recording and reading of information encoded in the medium, and the grasp of what is recorded, coded and transmitted as an intentional object, where the latter is construed in terms broadly in line with the ontologies of Husserl and Ingarden. Along the way, a number of issues relating to the notion of information are also pointed out: the problem of informational identity, of the existence of virtual objects, and of the choice of an adequate information carrier, as well as formal-ontological problems, including those which concern relations between information carriers and intentional objects.

Online technologies enable vast amounts of data to outlive their producers online, thereby giving rise to a new, digital form of afterlife presence. Although researchers have begun investigating the nature of such presence, academic literature has until now failed to acknowledge the role of commercial interests in shaping it. The goal of this paper is to analyse what those interests are and what ethical consequences they may have. This goal is pursued in three steps. First, we introduce the concept of (...) the Digital Afterlife Industry, and define it as an object of study. Second, we identify the politico-economic interests of the DAI. For this purpose, we develop an analytical approach based on an informational interpretation of Marxian economics. Third, we explain the practical manifestations of the interests using four real life cases. The findings expose the incentives of the DAI to alter what is referred to as the “informational bodies” of the dead, which in turn is to be seen as a violation of the principle of human dignity. To prevent such consequences, we argue that the ethical conventions that guide trade with remains of organic bodies may serve as a good model for future regulation of DAI. (shrink)

Information is usually supposed to be a prerequisite for people making decisions on whether or not to participate in a clinical trial. Previously conducted studies and research ethics scandals indicate that participants have sometimes lacked important pieces of information. Over the past few decades the quantity of information believed to be adequate has increased significantly, and in some instances a new maxim seems to be in place: the more information, the better the ethics in terms of (...) respecting a participant’s autonomy. The authors hypothesise that the dose-response curve from pharmacology or toxicology serves as a model to illustrate that a large amount of written information does not equal optimality. Using the curve as a pedagogical analogy when teaching ethics to students in clinical sciences, and also in engaging in dialogue with research institutions, may promote reflection on how to adjust information in relation to the preferences of individual participants, thereby transgressing the maxim that more information means better ethics.

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

Background 300 million operations and procedures are performed annually across the world, all of which require a patient’s informed consent. No standardised measure of the consent process exists in current clinical practice. We aimed to define a core outcome set for informed consent for therapy. Methods The core outcome set was developed in accordance with a predefined research protocol and the Core OutcoMes in Effectiveness Trials methodology comprising systematic review, qualitative semi structured interviews, a modified Delphi process and consensus webinars (...) to ratify outcomes for inclusion in the final core outcome set.. Participants from all key stakeholder groups took part in the process, including patients and the public, healthcare practitioners and consent researchers. Results 36 outcome domains were synthesised through systematic review and organised into a consent taxonomy. 41 semi-structured interviews were performed with all consent stakeholders groups. 164 participants from all stakeholder groups across 8 countries completed Delphi Round 1 and 125 completed Round 2. 11 outcomes met the ‘consensus in’ criteria. 6 met ‘consensus in’ all stakeholder groups and were included directly in the final core outcome set. 5 remaining outcomes meeting ‘consensus in’ were ratified over two consensus webinars. 9 core outcomes were included in the final core outcome set: Satisfaction with the quality and amount of information, Patient feeling that there was a choice, Patient feeling that the decision to consent was their own, Confidence in the decision made, Satisfaction with communication, Trust in the clinician, Patient satisfaction with the consent process, Patient rated adequacy of time and opportunity to ask questions. Conclusion This international mixed-methods qualitative study is the first of its kind to define a core outcome set for informed consent for intervention. It defines what outcomes are of importance to key stakeholders in the consent process and is a forward step towards standardising future consent research. (shrink)

An analysis of biological selection aimed at deriving a mechanism-independent definition removes Hull et al.'s obligatory requirement for replication of the carriers of information, under conditions, such as those obtaining in the nervous system, where the information content of a carrier can be modified without duplication by an amount controlled by the outcome of interactions with the environment.

The principle of 'information causality' can be used to derive an upper bound---known as the 'Tsirelson bound'---on the strength of quantum mechanical correlations, and has been conjectured to be a foundational principle of nature. In this paper, however, I argue that the principle has not to date been sufficiently motivated to play this role; the motivations that have so far been given are either unsatisfactorily vague or else amount to little more than an appeal to intuition. I then (...) consider how one might begin to successfully motivate the principle. I argue that a compelling way of so doing is to understand it as a generalisation of Einstein's principle of the mutually independent existence---the 'being-thus'---of spatially distant things, interpreted as a special methodological principle. More specifically: I describe an argument, due to Demopoulos, to the effect that the quantum-mechanical no-signalling condition can be viewed as a generalisation, appropriate to an irreducibly statistical theory such as quantum mechanics, of the Einsteinian principle. And I then argue that a compelling way to motivate information causality is to in turn consider it as a further generalisation of the Einsteinian principle that is appropriate to a theory of communication. I nevertheless describe important obstacles that must yet be overcome if the project of establishing information causality as a foundational principle of nature is to succeed. (shrink)

The amount of content, both on and offline, to which people in reasonably affluent nations have access has increased to the point that it has raised concerns that we are now suffering from a harmful condition of ‹information overload.’ Although the phrase is being used more frequently, the concept is not yet well understood – beyond expressing the rather basic idea of having access to more information than is good for us. This essay attempts to provide a (...) philosophical explication of the concept of information overload and is therefore what philosophers call ‹conceptual analysis’ – a task that, along with normative ethical analysis, is distinctive to Anglo-American style analytic philosophy. I will begin with an analysis of the atomic concepts expressed by the terms ‹information’ and ‹overload’ and then attempt to give a philosophical explanation of the concept of information overload that more precisely identifies exactly what the condition amounts to.

Most models of risky decision making assume that all relevant information is taken into account (e.g., Kahneman & Tversky, 1979; von Neumann & Morgenstern, 1944). However, there are also some models supposing that only part of the information is considered (e.g., Brandstätter, Gigerenzer, & Hertwig, 2006; Gigerenzer & Gaissmaier, 2011). To further investigate the amount of information that is usually used for decision making, and how the use depends on feedback, we conducted a series of three (...) experiments in which participants choose between two lotteries and where no feedback, outcome feedback, and error feedback was provided, respectively. The result show that without feedback participants mostly chose the lottery with the higher winning probability, and largely ignored the potential gains. The same result occurred when the outcome of each decision was fed back. Only after presenting error feedback (i.e., signaling whether a choice was optimal or not), participants considered probabilities as well as gains, resulting in more optimal choices. We propose that outcome feedback was ineffective, because of its probabilistic and ambiguous nature. Participants improve information integration only if provided with a consistent and deterministic signal such as error feedback. (shrink)

Assim, baseando-nos emum método qualitativo, apoiado na visão de Silverman (2000), concluímos que a rede de integração conceptual funciona de forma semelhante a uma máquina térmica de Carnot, na qual elementos são processados de forma a garantir a máxima eficiência.Palavras-chave: Integração conceptual.

AbstractIn this article, we aim at an epistemological parallelism between the conceptual blending (FAUCONNIER; TURNER, 2002) and the efficiency of a thermodynamic machine (CARNOT, 1824). Our hypothesis is that linguistic behavior amounts to a complex adaptive system (DUQUE, 2016) with maximum efficiency in its communicative processes in the same way as a thermodynamic machine. Supported by our object, namely the conceptual integration networks (SILVA, 2019), we perceive that the human being mixes concepts from many information fronts (frames) and composes a new conceptual structure, resulting from the amalgamation of information from these frames. Thus, based on the qualitative method supported by Silverman's (2000) vision, we conclude that the conceptual integration network works similarly to a Carnot thermal machine, in which elements are processed in order to ensure maximum efficiency.Keywords: Conceptual blending.

Treatment pressures are communicative strategies that mental health professionals use to influence the decision-making of mental health service users and improve their adherence to recommended treatment. Szmukler and Appelbaum describe a spectrum of treatment pressures, which encompasses persuasion, interpersonal leverage, offers and threats, arguing that only a particular type of threat amounts to informal coercion. We contend that this account of informal coercion is insufficiently sensitive to context and fails to recognize the fundamental power imbalance in mental healthcare. Based on (...) a set of counterexamples, we argue that what makes a proposal coercive is not whether service users will actually be made worse off if they reject the proposal, but rather whether they have the justified belief that this is the case. Whether this belief is justified depends on the presence of certain contextual factors, such as strong dependency on professionals and the salient possibility of formal coercion. (shrink)

It is both an ethical and a legal requirement that patients who participate in clinical trials must generally give their consent. As part of this process, patients must be provided with adequate information to enable them to decide whether or not to take part. In the UK, the pharmaceutical companies that sponsor such research, as well as Local Research Ethics Committees, specify in detail the information that must be given to trial participants. The researchers who conduct clinical trials (...) inevitably form views on the amount of information they are required to provide, and about patients’ comprehension of that information. The literature in this area suggests that some medical researchers may be unhappy with the amount of information that they must give patient participants. There have been, however, few systematic attempts to determine their views. This paper reports a study that explored researchers’ views as to (i) the amount of information provided to trial participants, and (ii) participants’ understanding of that information. Researchers generally felt that they were required to give trial participants an appropriate amount of information, and that most patients had at least a reasonable understanding of key aspects of the clinical trials’ process. However, there were differing views as to the level of information that they felt patients themselves wanted. The researchers did not generally feel that the patients’ inability to comprehend information rendered the process of obtaining ‘informed consent’ a waste of time. However, some did believe that they were required to burden patients with excessive information. (shrink)

Following the recent practice turn in privacy research, informational privacy is increasingly analyzed with regard to the “appropriate flow of information” within a given practice, which preserves the “contextual integrity” of that practice (Nissenbaum, 2010, p. 149; 2015). Such a practice-theoretical take on privacy emphasizes the normative structure of practices as well as its structural injustices and power asymmetries, rather than focusing on the intentions and moral considerations of individual or institutional actors. Since privacy norms are seen to be (...) institutionalized via the role obligations of the practice's participants, this approach can analyze structural and systematic privacy infringements in terms of “defective role performances and defective social relations” (Roessler & Mokrosinska, 2013, p. 780). -/- Unfortunately, it is still often somewhat unclear what this exactly means within the context of informational privacy, why these performances and relations are defective and for whom. This raises the common objection of a so-called “practice positivism” (Applbaum, 1999, p. 51), that is, the difficulty of practice–theoretical accounts to take a practice-independent standpoint, from which to normatively evaluate the existing practice norms themselves. For example, Nissenbaum herself initially argues for a “presumption in favor of the status quo” with respect to the appropriateness and flow of privacy norms within a practice (Nissenbaum, 2004, p. 127). Such a “practice conservatism” (Nissenbaum, 2010, p. 169) comes dangerously close to committing a naturalistic fallacy, if not undergirded by practice-external criteria (which is ultimately what she does). -/- Merely resorting to existing practice norms to assess what defective role performances amount to, only shifts the question from how to recognize an appropriate flow of information to the question of how to recognize those defective role performances and social relations. Against this backdrop, the central aim of this article is to shed light on this question without resorting to practice-independent first principles or far-reaching universalistic anthropological assumptions. For this, I will analyze the notion of “defective role performances and social relations” in terms of social pathologies.1 Doing so has two advantages: First of all, it can draw on already existing concepts and distinctions, which help to categorize the different levels of analysis that exist in informational privacy research and situate the notion of “defective role performances” within them (Section 1). Second, those concepts and distinctions can serve as a basis for establishing a typology of phenomena with regard to deficient practices of informational privacy (Section 4). (shrink)

A fascinating research program in neurophysiology attempts to quantify the amount of information transmitted by single neurons. The claims that emerge from this research raise new philosophical questions about the nature of information. What kind of information is being quantified? Do the resulting quantities describe empirical magnitudes like those found elsewhere in the natural sciences? In this article, it is argued that neural information quantities have a relativisitic character that makes them distinct from the kinds (...) of information typically discussed in the philosophical literature. It is also argued that despite this relativistic character, there are cases in which neural information quantities can be viewed as robustly objective empirical properties. (shrink)

The amount of information conveyed by linguistic conventions depends on their precision, yet the codes that humans and other animals use to communicate are quite ambiguous: they may map several vague meanings to the same symbol. How does semantic precision evolve, and what are the constraints that limit it? We address this question using a multiplayer gaming app, where individuals communicate with one another in a scaled-up referential game. Here, the goal is for a sender to use black (...) and white symbols to communicate colors. We expected that the players’ mappings between symbols and colors would grow more specific over time, through a selection process whereby precise mappings are preferentially copied. We found that players become increasingly more precise in their use of symbols over the course of their interactions. This trend did not, however, result from selective copying of precise mappings. We explore the implications of this result for the study of lexical ambiguity, Zipf's Law of Meaning, and disagreements over semantic conventions. (shrink)

In addition to the standard ellipsis process known as VP-ellipsis, another ellipsis process, known as pseudo-gapping, was first brought to the fore-front in the 1970’s by Sag (1976) and N. Levin (1986). This process elides subparts of a VP, as in (1): (1) Although I don’t like steak, I do___pizza. Developing ideas of K.S. Jayaseelan (Jayaseelan (1990)), Howard Lasnik has developed an analysis in which pseudo-gapping, which, in some instances, looks as though it is simply deleting a verb, is in (...) fact deletion of a verb phrase, so that pseudo-gapping is really a probe into the structure of the verb phrase. I will examine pseudo-gapping in detail, and will show that it truly is a gold mine of insight into a number of fundamental issues in syntax. More concretely, I will demonstrate that a careful, detailed analysis of this process will bear on the derivational level at which Principle A of the binding theory applies, as well as the amount of explicit encoding within syntactic representations of informational structure, particularly focus. The paper will also re-assess Lasnik’s conclusion that pseudo-gapping provides evidence for Larson’s (1988) V-raising to a higher empty V position, a case of head movement, and will show that the movement involved is actually a case of remnant movement, or XP-movement.

BackgroundEverybody has the right to decide whether to receive specific medical treatment or not and to provide their free, prior and informed consent to do so. As dementia progresses, people with Alzheimer’s dementia (PwAD) can lose their capacity to provide informed consent to complex medical treatment. When the capacity to consent is lost, the autonomy of the affected person can only be guaranteed when an interpretable and valid advance directive exists. Advance directives are not yet common in Germany, and their (...) validity is often questionable. Once the dementia diagnosis has been made, it is assumed to be too late to write an advance directive. One approach used to support the completion of advance directives is ‘Respecting Choices’®—an internationally recognised, evidence-based model of Advance Care Planning (ACP), which, until now, has not been evaluated for the target group of PwAD. This study’s aims include (a) to investigate the proportion of valid advance directives in a memory clinic population of persons with suspected AD, (b) to determine the predictors of valid advance directives, and (c) to examine whether the offer of ACP can increase the proportion of valid advance directives in PwAD.MethodWe intend to recruit at leastN = 250 participants from two memory clinics in 50 consecutive weeks. Of these, the first 25 weeks constitute the baseline phase (no offer of ACP), the following 25 weeks constitute the intervention phase (offer of ACP). The existence and validity of an advance directive will be assessed twice (before and after the memory clinic appointment). Moreover, potential predictors of valid advance directives are assessed.DiscussionThe results of this study will enhance the development of consent procedures for advance directives of PwAD based on the ACP/Respecting Choices (R) approach. Therefore, this project contributes towards increasing the autonomy and inclusion of PwAD and the widespread acceptance of valid advance directives in PwAD.Trial RegistrationDRKS, DRKS00026691, registered 15th of October 2021,https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00026691.

Fodor has argued that observation is theory neutral, since the perceptual systems are modular, that is, they are domain‐specific, encapsulated, mandatory, fast, hard‐wired in the organism, and have a fixed neural architecture. Churchland attacks the theoretical neutrality of observation on the grounds that (a) the abundant top‐down pathways in the brain suggest the cognitive penetration of perception and (b) perceptual learning can change in the wiring of the perceptual systems. In this paper I introduce a distinction between sensation, perception, and (...) observation and I argue that although Churchland is right that observation involves top‐down processes, there is also a substantial amount of information in perception which is theory‐neutral. I argue that perceptual learning does not threaten the cognitive impenetrability of perception, and that the neuropsychological research does not provide evidence in favor of the top‐down character of perception. Finally, I discuss the possibility of an off‐line cognitive penetrability of perception. (shrink)
