In lieu of an abstract, here is a brief excerpt of the content:The Neo-Idealist Reception of Kant in the Moscow Psychological SocietyRandall A. Poole*The Moscow Psychological Society, founded in 1885 at Moscow University, was the philosophical center of the revolt against positivism in the Russian Silver Age. By the end of its activity in 1922 it had played the major role in the growth of professional philosophy in Russia. 1 The Society owes its name to its founder, M. M. Troitsky (...) (1835–99), an empiricist psychologist. Although it sponsored significant psychological research, its greater importance in the history of Russian philosophy began to emerge already in 1888, when Nikolai Ia. Grot (1852–99) took over as director. Grot’s principal colleagues in the affairs of the Society included the major Russian idealist philosophers Vladimir S. Solov’ev (1853–1900), Sergei N. Trubetskoi (1862–1905), and Lev M. Lopatin (1855–1920). In 1889 the Psychological Society began publication of Russia’s first regular, specialized journal in philosophy, Questions of Philosophy and Psychology (Voprosy Filosofii i Psikhologii). Grot characterized the journal’s prevailing direction as idealist or, “in respect to method, metaphysical.” 2While the cultural revival of the Silver Age mounted a broad-based revolt against positivism, neo-idealist philosophy in the Psychological Society was distinctive in the theoretical depth of its critique. Positivism was remarkably pervasive [End Page 319] in Russia from the middle of the nineteenth century. The main characteristics of this positivist Weltanschauung were reductionism, which dismissed as a meaningless proposition (neither analytic nor empirical) the possibility of being beyond the positively-given data of sense experience, i.e., phenomena in space and time; scientism, the claim, consistent with the positivist reduction of being to natural phenomena, that the methodology of the natural sciences covered eve-rything; and utopianism, the hope that the application of natural scientific methods to man and society would make human existence as regular and well-ordered as nature. 3 The defining trait was reductionism or, in other words, naturalism or atheism: the reduction of being to nature. In ethics, epistemology, ontology, and social philosophy neo-idealism emerged as a response to these characteristics. Its development by philosophers in the Psychological Society, apart from comprising a basic chapter in the history of Russian thought, informs the European-wide revolt against positivism characteristic of fin-de-siècle culture.According to scientistic positivism, philosophy had no distinctive methodology and thus no legitimate right to exist as its own type of scientific (nauchnyi or wissenschaftlich) discipline. Empirical sciences were the only sciences; philosophy could at best serve as a field that systematized empirical research. Against these claims Russian neo-idealists sought to advance the autonomy of philosophy by showing that the positivist measure of reality was far from exhaustive and that what it did not exhaust comprised the domain of philosophy. This domain was human consciousness itself, to the extent it could be shown to be irreducible to empirical experience (the positivist sphere). Neo-idealism thus took shape as a type of philosophy of consciousness. In the inaugural issue of Questions of Philosophy and Psychology S. N. Trubetskoi published the first installment of a large essay bearing the title, “On the Nature of Human Consciousness.” “The question of the nature of consciousness is the principal question of philosophy, not only of psychology,” Trubetskoi wrote, “for in consciousness we know everything that we know.” 4 Trubetskoi and his colleagues in the Psychological Society were convinced that philosophy had to develop through specification of its own internal standards and through autonomization from the spurious criteria positivism applied externally to it. Their goal was to match, in theoretical rigor, the professionalism associated with the natural sciences by making philosophy “scientific,” but on idealist, not empirical grounds. [End Page 320]The Kantian Critique of PositivismIn their defense of the self against positivist reductionism and naturalism, neo-idealists of the Psychological Society were deeply indebted to Kant, in both epistemology and moral philosophy. This claim revises the traditional view that Russian philosophy developed without significant assistance from Kant. 5In two ways Kant’s Critique of Pure Reason defends the minimal idealist claim that not everything intellectual can be reduced to the natural (sensible or psychological), that consciousness cannot...

Long-term ecological research (LTER), addressing problems that encompass decadal or longer time frames, began as a formal term and program in the United States in 1980. While long-term ecological studies and observation began as early as the 1400s and 1800s in Asia and Europe, respectively, the long-term approach was not formalized until the establishment of the U.S. long-term ecological research programs. These programs permitted ecosystem-level experiments and cross-site comparisons that led to insights into the biosphere’s structure and function. The holistic (...) ecosystem approach of this initiative also allowed the incorporation of the human-dimension of ecology and recently has given rise to a new concept of long-term socio-ecological research (LTSER). Today, long-term ecological research programs exist in at least thirty-two countries (i.e., members of the International Long-Term Ecological Research Network, ILTER). However, consolidation of the international network within the long-term socio-ecological research paradigm still requires: (1) inclusion of certain remote regions of the world, such as southwestern South America, that are still poorly represented; (2) modifications of the type of research conducted, such as integrating social and natural sciences with the humanities and ethics; and (3) the incorporation of findings and results into broader social and political processes. In this context, a nascent long-term socio-ecological research network in Chile, which extends over the longest latitudinal range of temperate forest in the Southern Hemisphere, adds a new remote region to international long-term ecological research previously overlooked. In addition, collaboration with the University of North Texas and other international partners helps to further develop an interdisciplinary approach for the integration of the ecological sciences and environmental philosophy together with traditional ecological knowledge, informal and formal education, policy, the humanities, socio-political processes, and biocultural conservation.

"This book focuses on a vibrant central current within the history of Russian legal thought: how Christianity, and theistic belief generally, has inspired the aspiration to the rule of law in Russia, informed Russian philosophies of law, and shaped legal practices. In this volume, a team of Western and Russian scholars presents fourteen concise, non-technical portraits of modern Russian jurists and philosophers of law whose thought was shaped significantly by Orthodox Christian faith or theistic belief. Each portrait provides essential biographical (...) information, a description of the jurist's religious views, and a substantive account of the subject's jurisprudential ideas. Each chapter ends with a word about the jurist's legacy in Russia today. The collection embraces the most creative period of Russian legal thought, the century and a half from the later Enlightenment to the Russian emigration following the Bolshevik Revolution and Civil War of 1917-1921. While many of the figures represented in this gallery were liberals, in various sense of the term, the volume reaches across the ideological spectrum. Contributors to the volume include respected senior authorities together with younger scholars of exceptional promise. This book will merit the attention of anyone interested in exploring the connections between law and religion in modern times"--. (shrink)

Background HIV prevention trials conducted among disadvantaged vulnerable at-risk populations in developing countries present unique ethical dilemmas. A key concern in bioethics is the validity of informed consent for trial participation obtained from research subjects in such settings. The purpose of this study was to investigate the effectiveness of a continuous informed consent process adopted during the MDP301 phase III vaginal microbicide trial in Mwanza, Tanzania. Methods A total of 1146 women at increased risk of HIV acquisition working as alcohol (...) and food vendors or in bars, restaurants, hotels and guesthouses have been recruited into the MDP301 phase III efficacy and safety trial in Mwanza. During preparations for the trial, participatory community research methods were used to develop a locally-appropriate pictorial flipchart in order to convey key messages about the trial to potential participants. Pre-recorded audio tapes were also developed to facilitate understanding and compliance with gel-use instructions. A comprehension checklist is administered by clinical staff to all participants at screening, enrolment, 12, 24, 40 and 50 week follow-up visits during the trial. To investigate women's perceptions and experiences of the trial, including how well participants internalize and retain key messages provided through a continuous informed consent process, a random sub-sample of 102 women were invited to participate in in-depth interviews conducted immediately after their 4, 24 and 52 week follow-up visits. Results 99 women completed interviews at 4-weeks, 83 at 24-weeks, and 74 at 52 weeks. In all interviews there was evidence of good comprehension and retention of key trial messages including that the gel is not currently know to be effective against HIV; that this is the key reason for conducting the trial; and that women should stop using gel in the event of pregnancy. Conclusions Providing information to trial participants in a focussed, locally-appropriate manner, using methods developed in consultation with the community, and within a continuous informed-consent framework resulted in high levels of comprehension and message retention in this setting. This approach may represent a model for researchers conducting HIV prevention trials among other vulnerable populations in resource-poor settings.

La investigación ecológica a largo plazo (Long Term Ecological Research, LTER) maneja problemas que abarcan décadas o plazos más largos. El programa y su nombre formal comenzaron en Estados Unidos en 1980. Si bien los estudios y observaciones a largo plazo comenzaron tempranamente en 1400 y 1800 en Asia y Europa, respectivamente, el enfoque a largo plazo no se formalizó sino hasta el establecimiento de los programas de investigación ecológica de largo plazo en Estados Unidos. Estos programas han permitido experimentos (...) a nivel de ecosistemas y comparaciones entre sitios que condujeron a una mejor comprensión de la estructura y funcionamiento de la biosfera. El enfoque ecosistémico holístico de esta iniciativa permite también la incorporación de la dimensión humana en la ecología, y recientemente ha dado lugar al nuevo concepto de investigación socio-ecológica de largo plazo (LTSER). Hoy los programas de investigación socio-ecológica a largo plazo existen en por lo menos 32 países (esto es, los miembros de la Red Internacional de Investigación Ecológica a Largo Plazo o ILTER (International Long Term Ecological Research). Sin embargo, la consolidación de la red internacional dentro del paradigma de investigación socio-ecológica a largo plazo todavía requiere: (1) inclusión de algunas regiones remotas del mundo que aún están poco representadas, como el suroeste de América del Sur; (2) modificaciones en el tipo de investigación realizado, tales como la integración de las ciencias sociales y naturales con las humanidades y la ética, y (3) la incorporación de las conclusiones y resultados dentro de los procesos sociales y políticos. En este contexto, la naciente red de investigación socio-ecológica a largo plazo en Chile, que se extiende en el rango latitudinal más largo de bosque templado en el Hemisferio Sur, agrega una nueva región remota a las investigaciones ecológicas de largo plazo que había sido pasada por alto anteriormente. Además, la colaboración con la Universidad de North Texas y otros asociados internacionales ayuda a desarrollar un enfoque interdisciplinario para integrar las ciencias ecológicas y la filosofía ambiental, junto con los conocimientos ecológicos tradicionales, la educación informal y formal, la política, las humanidades, los procesos socio-políticos y la conservación biocultural.

Social media platforms offer convenient, instantaneous social sharing on a mass scale with tremendous impact on public perceptions, opinions, and behavior. There is a need to understand why information spreads including the human motivations, cognitive processes, and neural dynamics of large-scale sharing. This study introduces a novel approach for investigating the effect social media messaging and in-person discussion has on the inter-brain dynamics within small groups of participants. The psychophysiological impact of information campaigns and narrative messaging within a (...) closed social media environment was assessed using 24-channel wireless EEG. Data were acquired from three- or four-person groups while subjects debated contemporary social issues framed by four scenarios of varying controversy: investing in ethical vs. unethical corporations, selecting travel destination based on social awareness, determining verdict in a murder trial and the punishment of life in prison or death penalty, and decision to vaccinate. Pre-/post-scenario questionnaires assess the effects of the social media information. Inter-brain coherence between subject pairs on each social issue discussed by subjects was analyzed by concordance, agreement vs. disagreement, and by group unanimity, unanimous vs. not unanimous. Subject pairs that agreed on the social issues raised in the scenarios had significantly greater inter-brain coherence in gamma frequency range than disagreeing pairs over cortical regions known to be involved in social interactions. These effects were magnified when comparing groups where subject pairs were unanimous in their stance on the social issues for some but not all scenarios. While there was considerable overlap between scenarios in what EEG channels were significant, there was enough variability to indicate the possibility of scenario-specific effects on inter-brain coherence.

In one-shot public goods dilemmas, defection is the strictly dominant strategy. However, agents with cooperative strategies can do well if (1) agents are `translucent' (that is, if agents can fallibly recognize the strategy other agents play ex ante ) and (2) an institutional structure allows `assortation' such that cooperative agents can increase the likelihood of playing with their own kind. The model developed in this article shows that even weak levels of translucency suffice if cooperators are able to pool their (...) information to exclude defectors. Computer simulations confirm this claim. The results imply that conditional cooperation can be a successful strategy given translucency and `assortation', even if the game has a one-shot character. The article discusses implications for moral theory against the backdrop of `virtual self-regard' and the concept of moral integrity. Key Words: public good • game theory • prisoner's dilemma • translucency • assortation • group formation • group identity • integrity • altruism. (shrink)

Models of collective deliberation often assume that the chief aim of a deliberative exchange is the sharing of information. In this paper, we argue that an equally important role of deliberation is to draw participants’ attention to pertinent questions, which can aid the assembly and processing of distributed information by drawing deliberators’ attention to new issues. The assumption of logical omniscience renders classical models of agents’ informational states unsuitable for modelling this role of deliberation. Building on recent insights (...) from psychology, linguistics and philosophy about the role of questions in speech and thought, we propose a different model in which beliefs are treated as answers directed at specific questions. Here, questions are formally represented as partitions of the space of possibilities and individuals’ information states as sets of questions and corresponding partial answers to them. The state of conversation is then characterised by individuals’ information together with the questions under discussion, which can be steered by various deliberative inputs. Using this model, deliberation is then shown to shape collective decisions in ways that classical models cannot capture, allowing for novel explanations of how group consensus is achieved. (shrink)

In their article, McKelvey and Page note that In previous experimental work, ... [researchers] investigated how individuals use public information to augment their original private information, and whether in doing so, a rational expectations equilibrium is attained. ... [But either] the inference processes are complicated because of the enormous number of potential interactions among the individuals, and the optimal inference processes are not analyzed. ... [or] the inference process is analyzed but the working assumption is not altogether satisfactory.

If a group as a whole is modelled as a single Bayesian agent, what should its beliefs be? I propose an axiomatic model that connects group beliefs to beliefs of group members, who are themselves modelled as Bayesian agents, possibly with di¤erent priors and di¤erent information. Group beliefs are shown to take a simple multiplicative form if people’s information is independent, and a more complex form if information can overlap arbitrarily. This shows that group beliefs can incorporate (...) all information spread over the individuals without the individuals having to communicate their (possibly complex and hard-to-describe) private information; communicating prior and posterior beliefs su¢ ces.

Developing countries are endeavoring to advance into the 21st century information age. Their progress, however, is hamstrung by the dire lack of trained, skilled and knowledgeable IS workers who are able to interact with online and off‐line information sources. These countries can tap from the rich intellectual capital lying dormant within the ranks of disabled people to boost the pool of IS workers in their societies. However, before developing countries can draw on the information systems capabilities of (...) disabled workers, these workers themselves must be able to function at par with their able‐bodied counterparts as information workers. This presupposes the availability of special‐purpose information systems devices and approaches developed for disabled users. In this paper, therefore, we examine several issues that are pertinent to IS and disabled people in developing countries, and propose an integrated infrastructure to enhance the interaction of disabled people with on‐line information sources. The study includes issues related to the suitability of different interaction methodologies and technologies for people with disabilities. Additionally, we propose the design of customized interfaces that can be used by disabled people to develop Web‐based database applications and to access and query on‐line databases. (shrink)

Much of our information comes to us indirectly, in the form of conclusions others have drawn from evidence they gathered. When we hear these conclusions, how can we modify our own opinions so as to gain the benefit of their evidence? In this paper we study the method known as geometric pooling. We consider two arguments in its favour, raising several objections to one, and proposing an amendment to the other.

Summary This paper reports on the perspectives of elite athletes on anti-doping work in general and on the whereabouts system in particular, and uses a figurational perspective to explore the unintended consequences of the planned introduction of the whereabouts system. A cross-sectional survey of all the athletes in the Norwegian registered testing pool was carried out in 2006, using a structured questionnaire. Overall, 70.6% of the athletes agreed that doping was a problem in elite sport in general, but paradoxically only (...) 17.5% agreed that doping was a problem in their own sport. However, more than four in ten of the athletes agreed that the whereabouts information system made a contribution to a “cleaner” sport. Some athletes thought the system was unfair. The whereabouts information system had, despite all good intentions, outcomes other than those planned and intended by the WADA. Thus, athletes’ views might fruitfully be integrated with other perspectives when anti-doping work is developed further. (shrink)

The use of algorithmic prediction in insurance is regarded as the beginning of a new era, because it promises to personalise insurance policies and premiums on the basis of individual behaviour and level of risk. The core idea is that the price of the policy would no longer refer to the calculated uncertainty of a pool of policyholders, with the consequence that everyone would have to pay only for her real exposure to risk. For insurance, however, uncertainty is not only (...) a problem – shared uncertainty is a resource. The availability of individual risk information could undermine the principle of risk-pooling and risk-spreading on which insurance is based. The article examines this disruptive change first by exploring the possible consequences of the use of predictive algorithms to set insurance premiums. Will it endanger the principle of mutualisation of risks, producing new forms of discrimination and exclusion from coverage? In a second step, we analyse how the relationship between the insurer and the policyholder changes when the customer knows that the company has voluminous, and continuously updated, data about her real behaviour.

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of (...) each class of pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

We establish completeness and the finite model property for logics featuring the pooling modalities that were introduced in Van De Putte and Klein. The definition of our canonical models combines standard techniques with a so-called “puzzle piece construction”, which we first illustrate informally. After that, we apply it to the weakest classical logics with pooling modalities and investigate the technique’s potential for the axiomatization of stronger logics, obtained by imposing well-known frame conditions on the models.

Purpose This paper aims to look at shifts in internet-related content and services economies, from audience labour economies to Web 2.0 user-generated content, and the emerging model of user computing power utilisation, powered by blockchain technologies. The authors look at and test three models of user computing power utilisation based on distributed computing two of which use cryptocurrency mining through distributed pool mining techniques, while the third is based on distributed computing of calculations for scientific research. The three models promise (...) benefits to their users, which the authors discuss throughout the paper, studying how they interplay with the three levels of the digital divide. Design/methodology/approach The goal of this article is twofold as follows: first to discuss how using the mining hype may reduce digital inequalities, and secondly to demonstrate how these services offer a new business model based on value rewarding in exchange for computational power, which would allow more online opportunities for people, and thus reduce digital inequalities. Finally, this contribution discusses and proposes a method for a fair revenue model for content and online service providers that uses user device computing resources or computational power, rather than their data and attention. The method is represented by a model that allows for consensual use of user computing resources in exchange for accessing content and using software tools and services, acting essentially as an alternative online business model. Findings Allowing users to convert their devices’ computational power into value, whether through access to services or content or receiving cryptocurrency and payments in return for providing services or content or direct computational powers, contributes to bridging digital divides, even at fairly small levels. Secondly, the advent of blockchain technologies is shifting power relations between end-users and content developers and service providers and is a necessity for the decentralisation of internet and internet services. Originality/value The article studies the effect of services that rely on distributed computing and mining on digital inequalities, by looking at three different case studies – Coinhive, Gridcoin and Cryptotab – that promise to provide value in return for using computing resources. The article discusses how these services may reduce digital inequalities by affecting the three levels of the digital divide, namely, access to information and communication technologies, skills and motivations in using ICTs and capacities in using ICTs to get concrete benefits.

Velmans (1991a; 1991b) proposed that consciousness plays a minor explanatory role in the information processing approach and that unconscious mechanisms process stimuli and responses and intervene between them. In contrast, the present commentary describes a thought experiment suggesting that, although input information is initially processed unconsciously, subsequent processing involves consciousness, and consciousness plays an important role in the explanation of behavior.

In this paper, I propose and defend a distinct and novel approach to compensation for risk impositions. I call it the Risk-Pooling System of compensation. This system suggests that when X performs an action that imposes a risk of harm to Y, then X is liable to Y, and is therefore obliged to make an ex ante compensation that is roughly equivalent to the expected cost of potential harm to a social- risk pool. If and when Y suffers harm (...) as a result of the risk imposed by X, they then receive an ex post compensation roughly equivalent to the cost of actual harm suffered. This system of compensation creates a social buffer between the risk imposer – the one who has the duty to pay compensation into the pool – and the victim – the one who has the right to receive compensation from the social pool. I contend that the Risk-Pooling System is an improvement over its alternatives due to its capacity to produce the best social utilities, particularly, in terms of reducing information costs, obtaining optimal deterrence in the society and creating incentives for people to be engaged in social activities.

We show how Poole-systems, a simple approach to nonmonotonic reasoning, can be extended to take meta-information into account adequately. The meta-information is used to guide the choice of formulas accepted by the reasoner as premises. Existence of a consistent set of conclusions is guaranteed by a least fixpoint construction. The proposed formalism has useful applications in defeasible reasoning, knowledge base fusion and belief revision.

We consider the problems arising from using sequences of experiments to discover the causal structure among a set of variables, none of whom are known ahead of time to be an “outcome”. In particular, we present various approaches to resolve conflicts in the experimental results arising from sampling variability in the experiments. We provide a sufficient condition that allows for pooling of data from experiments with different joint distributions over the variables. Satisfaction of the condition allows for an independence (...) test with greater sample size that may resolve some of the conflicts in the experimental results. The pooling condition has its own problems, but should—due to its generality—be informative to techniques for meta-analysis. (shrink)

Information is a peculiar quantity. Unlike matter and energy, which are conserved by the laws of physics, the aggregation of knowledge from many sources can in fact produce more information (synergy) or less (redundancy) than the sum of its parts. This feature can endow groups with problem‐solving strategies that are superior to those possible among noninteracting individuals and, in turn, may provide a selection drive toward collective cooperation and coordination. Here we explore the formal properties of information (...) aggregation as a general principle for explaining features of social organization. We quantify information in terms of the general formalism of information theory, which also prescribes the rules of how different pieces of evidence inform the solution of a given problem. We then show how several canonical examples of collective cognition and coordination can be understood through principles of minimization of uncertainty (maximization of predictability) under information pooling over many individuals. We discuss in some detail how collective coordination in swarms, markets, natural language processing, and collaborative filtering may be guided by the optimal aggregation of information in social collectives. We also identify circumstances when these processes fail, leading, for example, to inefficient markets. The contrast to approaches to understand coordination and collaboration via decision and game theory is also briefly discussed. (shrink)

I introduce an extension of the Lewis-Skyrms signaling game, analysed from a dynamical perspective via simple reinforcement learning. In Lewis’ (Convention, Blackwell, Oxford, 1969) conception of a signaling game, salience is offered as an explanation for how individuals may come to agree upon a linguistic convention. Skyrms (Signals: evolution, learning & information, Oxford University Press, Oxford, 2010a) offers a dynamic explanation of how signaling conventions might arise presupposing no salience whatsoever. The extension of the atomic signaling game examined here—which (...) I will refer to as a salience game—introduces a variable parameter into the atomic signaling game which allows for degrees of salience, thus filling in the continuum between Skyrms’ and Lewis’ models. The model does not presuppose any salience at the outset, but illustrates a process by which accidentally evolved salience is amplified, to the benefit of the players. It is shown that increasing degrees of salience allow populations to avoid sub-optimal pooling equilibria and to coordinate upon conventions more quickly. (shrink)

Fundamental problems of environmental sustainability, including climate change and fisheries management, require collective action on a scale that transcends the political and cultural boundaries of the nation-state. Rational, self-interested neoclassical economic theories of human behavior predict tragedy in the absence of third party enforcement of agreements and practical difficulties that prevent privatization. Evolutionary biology offers a theory of cooperation, but more often than not in a context of discrimination against other groups. That is, in-group boundaries are necessarily defined by those (...) excluded as members of out-groups. However, in some settings human’s exhibit behavior that is inconsistent with both rational economic and group driven cooperation of evolutionary biological theory. This paper reports the results of a non-cooperative game-theoretic exercise that models a tragedy of the commons problem in which groups of players may advance their own positions only at the expense of other groups. Students enrolled from multiple universities and assigned to different multi-university identity groups participated in experiments that repeatedly resulted in cooperative outcomes despite intergroup conflicts and expressions of group identity. We offer three possible explanations: students were cooperative because they were in an academic setting; students may have viewed their instructors as the out-group; or the emergence of a small number of influential, ethical leaders is sufficient to ensure cooperation amongst the larger groups. From our data and analysis, we draw out lessons that may help to inform approaches for institutional design and policy negotiations, particularly in climate change management. (shrink)

Transfer of information between senders and receivers, of one kind or another, is essential to all life. David Lewis introduced a game theoretic model of the simplest case, where one sender and one receiver have pure common interest. How hard or easy is it for evolution to achieve information transfer in Lewis signaling?. The answers involve surprising subtleties. We discuss some if these in terms of evolutionary dynamics in both finite and infinite populations, with and without mutation.

Prominent philosophers have argued that contradictions contain either too much or too little information to be useful. We dispute this with what we call the “Paradox of the Two Firefighters.” Suppose you are awakened in your hotel room by a fire alarm. You open the door. You see three possible ways out: left, right, straight ahead. You see two firefighters. One says there is exactly one safe route and it is to your left. The other says there is exactly (...) one safe route and it is to your right. While the two firemen are giving you contradictory information, they are also both giving you the perhaps useful information that there is a safe way out and it is not straight ahead. We give two analyses. The first uses the “Opinion Tetrahedron,” introduced by Dunn as a generalization of Audun Jøsang’s “Opinion Triangle.” The Opinion Tetrahedron in effect embeds the values of the “Belnap-Dunn 4-valued Logic” into a context of subjective probability generalized to allow for degrees of belief, disbelief, and two kinds of uncertainty—that in which the reasoner has too little information and that in which the reasoner has too much information. Jøsang had only a single value for uncertainty. We also present an alternative solution, again based on subjective probability but of a more standard type. This solution builds upon “linear opinion pooling.” Kiefer had already developed apparatus for assessing risk using expert opinion, and this influences the second solution. Finally, we discuss how these solutions might apply to “Big Data” and the World Wide Web. (shrink)

Metacognition, the ability to monitor and evaluate our own cognitive processes, confers advantages to individuals and their own judgment. A more recent hypothesis, however, states that explicit metacognition may also enhance the collective judgment of groups, and may enhance human collaboration and coordination. Here, we investigate this social function hypothesis of metacognition with arguably one of the oldest collaboration problems humans face, common-pool resource use. Using an agent-based model that simulates repeated group interactions and the forming of collective judgments about (...) resource extraction, we show that (1) in “kind” environments (where confidence and judgment accuracy correlate positively), explicit metacognition may allow groups to reach more accurate judgments compared to groups exchanging object-level information only; while (2) in “wicked” environments (where confidence and judgment accuracy correlate negatively), explicit metacognition may protect groups from the large judgment errors yielded by groups using metacognitive information for individual-level learning only (implicit metacognition). With explicit metacognition, this research highlights a novel mechanism which, among others, provides a testable explanation of the often-observed finding that groups all over the world communicate to enhance common property use.

The existing research aims to seek the herding effects on stock returns at the industry level in Pakistan Stock Exchange. Moreover, the relationship between stock returns and herding has been studied by taking some macroeconomic and fundamental control variables. Herding is actually imitating other’s behaviour. This phenomenon indicates a situation where the investors follow the crowed and ignores their personal information, despite knowing the correctness of their information. Herd behaviour may drive from fundamental factors leading to efficient markets. (...) However, it may not be associated with fundamental information causing unstable prices. The stock price data of PSX listed companies from 1999 to 2017 have been the point of focus. The underlying herding measure was the cross-sectional absolute deviation, proposed by Chang et al.. The significant analysis technique facilitating the current research is pooled mean group /panel autoregressive distributed lag approach. Findings revealed that some sectors are evident for positive effect of herding on stock returns, whereas some others are witnessed for its negative effects on stock returns, in both long run and short run. As far as the control variables are concerned, they demonstrated both significant and insignificant effects on stock returns in different sectors of PSX. The study has important implications for policymakers. (shrink)

In the half-century history of clinical practice of diagnosing brain death, informed consent has seldom been considered until very recently. Like many other medical diagnoses and ordinary death pronouncements, it has been taken for granted for decades that brain death is diagnosed and death is declared without consideration of the patient’s advance directives or family’s wishes. This essay examines the pros and cons of using informed consent before the diagnosis of brain death from an ethical point of view. As shared (...) decision-making in clinical practice became increasingly indispensable, respect for the patients’ autonomous wishes regarding how to end their lives has a significant role in deciding how death is diagnosed. Brain death, as a fully technologically controlled death, may require a different ethical framework from the old one for traditional cardiac death. With emerging and proliferating options in end-of-life care for those who suffer from catastrophic brain injury, the traditional reasoning that ‘death gives no choice, hence no consent’ requires another examination. Patients facing imminent brain death now have options other than undergoing the diagnostic workup for brain death, such as donation after circulatory death and withdrawal of life-sustaining treatment with maximum comfort measures for death with dignity. Nevertheless, just as in the debate over opt-in versus opt-out organ donation policies, informed consent before the diagnosis of brain death faces fierce opposition from consequentialists urging the expansion of the donor pool. This essay examines these objections and provides constructive replies along with a proposal to accommodate this morally required consent. (shrink)

One of the major puzzles in evolutionary theory is how communication and information transfer are possible when the interests of those involved conflict. Perfect information transfer seems inevitable if there are physical constraints, which limit the signal repertoire of an individual, effectively making bluffing an impossibility. This, I argue, is incorrect. Unfakeable signals by no means guarantee information transfer. I demonstrate the existence of a so-called pooling equilibrium and discuss why the traditional argument for perfect (...) class='Hi'>information transfer does not hold in all cases. Additionally, I demonstrate that deception is possible at equilibrium despite the fact that signals are impossible to fake. (shrink)

BackgroundBayesian estimation with informative priors permits updating previous findings with new data, thus generating cumulative knowledge. To reduce subjectivity in the process, the present study emphasizes how to systematically weigh and specify informative priors and highlights the use of different aggregation methods using an empirical example that examined whether observed mother-adolescent positive and negative interaction behavior mediate the associations between maternal and adolescent internalizing symptoms across early to mid-adolescence in a 3-year longitudinal multi-method design.MethodsThe sample consisted of 102 mother-adolescent dyads. (...) Mothers and adolescents reported on their internalizing symptoms and their interaction behaviors were observed during a conflict task. We systematically searched for previous studies and used an expert-informed weighting system to account for their relevance. Subsequently, we aggregated the priors using three methods: linear pooling, logarithmic pooling, and fitting a normal distribution to the linear pool by means of maximum likelihood estimation. We compared the impact of the three differently specified informative priors and default priors on the prior predictive distribution, shrinkage, and the posterior estimates.ResultsThe prior predictive distributions for the three informative priors were quite similar and centered around the observed data mean. The shrinkage results showed that the logarithmic pooled priors were least affected by the data. Most posterior estimates were similar across the different priors. Some previous studies contained extremely specific information, resulting in bimodal posterior distributions for the analyses with linear pooled prior distributions. The posteriors following the fitted normal priors and default priors were very similar. Overall, we found that maternal, but not adolescent, internalizing symptoms predicted subsequent mother-adolescent interaction behavior, whereas negative interaction behavior seemed to predict subsequent internalizing symptoms. Evidence regarding mediation effects remained limited.ConclusionA systematic search for previous information and an expert-built weighting system contribute to a clear specification of power priors. How information from multiple previous studies should be included in the prior depends on theoretical considerations, and may also be affected by pragmatic considerations regarding the impact of the previous results at hand.

Alzheimer’s disease is the most common form of dementia which is estimated to impact 350,000 people over 65 years of age in Canada. The lack of effective treatment and the growing number of people who are expected to be diagnosed with Alzheimer’s disease in the near future are compelling reasons why continued research is in this area is necessary. With additional research, there needs to be greater recognition of the complexity of seeking ongoing informed consent from those with Alzheimer’s disease. (...) This complexity is because the impairment of memory and cognitive ability does not diminish in a linear manner, but rather fluctuates between periods of impairment and relatively normal cognitive lucidness. There is limited discussion in the guidelines of those progressing from early stages of Alzheimer’s disease who have intermittent cognitive function. Guidelines to research and Research Ethics Boards require further development to facilitate researcher including those with Alzheimer’s disease while protecting this growing pool of potential participants.

In order to facilitate the informed consent process, we suggest recording it. If investigators routinely recorded the consent process—including subsequent testing of participants’ comprehension and reeducation efforts—they could monitor the consent practices of their staff and determine what changes in procedure may be needed. In addition, should the adequacy of consent ever be challenged , investigators would have an easily accessible record of what had transpired. And finally, a pool of data would be created that could be accessed by researchers (...) who study informed consent issues and are interested in identifying ways of further improving the process.

Purpose Human genomic research demands very large pools of data to generate meaningful inference. Yet, the sharing of one’s genetic data for research is a voluntary act. The collection of data sufficient to fuel rapid advancement is contingent on individuals’ willingness to share. Privacy risks associated with sharing this unique and intensely personal data are significant. Genetic data are an unambiguous identifier. Public linkage of donor to their genetic data could reveal predisposition to diseases, behaviors, paternity, heredity, intelligence, etc. The (...) purpose of this paper is to understand individuals’ willingness to volunteer their private information in this high-risk/high-reward context. Design/methodology/approach The authors collect survey data from 273 respondents and use structural equation modeling techniques to analyze responses. Findings The authors find statistical support for our theorization. They find that while heightened awareness of the benefits and risks of sharing correlates with increased privacy concerns, the net impact is an increase in intention to share. Social implications The findings suggest that prescriptive awareness might be an effective tool with which policy-makers can gain the sufficient voluntary participation from individuals necessary to drive large-scale medical research. Originality/value This study contributes a theoretically and empirically informed model which demonstrates the impact of awareness and privacy concern on individuals’ willingness to share their genetic data for large-scale HGR. It helps inform a rising class of data sufficiency problems related to large-scale medical research. (shrink)

A desirable property of a diversity index is strict concavity. This implies that the pooled diversity of a given community sample is greater than or equal to but not less than the weighted mean of the diversity values of the constituting plots. For a strict concave diversity index, such as species richness S, Shannon''s entropy H or Simpson''s index 1-D, the pooled diversity of a given community sample can be partitioned into two non-negative, additive components: average within-plot diversity and between-plot (...) diversity. As a result, species diversity can be summarized at various scales measuring all diversity components in the same units. Conversely, violation of strict concavity would imply the non-interpretable result of a negative diversity among community plots. In this paper, I apply this additive partition model generally adopted for traditional diversity measures to Aczél and Daróczy''s generalized entropy of type . In this way, a parametric measure of -diversity is derived as the ratio between the pooled sample diversity and the average within-plot diversity that represents the parametric analogue of Whittaker''s -diversity for data on species relative abundances.

This paper examines the cosmological theories of Francis Lodwick (1619-94), the Fellow of the Royal Society, language theorist and close associate of Robert Hooke, concentrating on some unnoticed manuscripts he wrote on this issue. It is demonstrated that Lodwick's account of creation acts as a commentary on the opening chapters of Genesis, influenced in equal measures by the new corpuscular philosophy, and by the heretical, messianic ideas of the Frenchman Isaac La Peyrere, whose Prae-Adamitae (1655) so shocked European scholars. Such (...) a conclusion emphasizes that in the case of Lodwick no clear distinction between biblical criticism and natural philosophy can be maintained, and that the theological ideas he brought to his vortical model of creation were strongly heretical. Such a situation contradicts the proposition insisted upon by early apologists for the Royal Society that the institutionalizing of scientific work would promote orthodox Christianity. (shrink)

In recent years, critical scholarship has drawn attention to increasing power differentials between corporations that use data and people whose data is used. A growing number of scholars see digital data and information commons as a way to counteract this asymmetry. In this paper I raise two concerns with this argument: First, because digital data and information can be in more than one place at once, governance models for physical common-pool resources cannot be easily transposed to digital commons. (...) Second, not all data and information commons are suitable to address power differentials. In order to create digital commons that effectively address power asymmetries we must pay more systematic attention to the issue of exclusion from digital data and information commons. Why and how digital data and information commons exclude, and what the consequences of such exclusion are, decide whether commons can change power asymmetries or whether they are more likely to perpetuate them.

Many countries have imposed strict regulations on the genetic information to which insurers have access. Commentators have warned against the emerging body of legislation for different reasons. This paper demonstrates that, when confronted with the argument that genetic information should be available to insurers for health insurance underwriting purposes, one should avoid appeals to rights of genetic privacy and genetic ignorance. The principle of equality of opportunity may nevertheless warrant restrictions. A choice-based account of this principle implies that (...) it is unfair to hold people responsible for the consequences of the genetic lottery, since we have no choice in selecting our genotype or the expression of it. However appealing, this view does not take us all the way to an adequate justification of inaccessibility of genetic information. A contractarian account, suggesting that health is a condition of opportunity and that healthcare is an essential good, seems more promising. I conclude that if or when predictive medical tests (such as genetic tests) are developed with significant actuarial value, individuals have less reason to accept as fair institutions that limit access to healthcare on the grounds of risk status. Given the assumption that a division of risk pools in accordance with a rough estimate of people's level of (genetic) risk will occur, fairness and justice favour universal health insurance based on solidarity.

This paper argues that management practices are more readily portable across the sectors than has often been supposed, while indicating where particular care will be needed in translation. The paper suggests, however, that political pressure for control and an epistemological bias may prove to be management's Achilles heel. Further, it examines some dilemmas in the relationship between the manager and the managed, and queries the professions' outrage at being subject to increasingly overt management.

Merging of opinions results underwrite Bayesian rejoinders to complaints about the subjective nature of personal probability. Such results establish that sufficiently similar priors achieve consensus in the long run when fed the same increasing stream of evidence. Initial subjectivity, the line goes, is of mere transient significance, giving way to intersubjective agreement eventually. Here, we establish a merging result for sets of probability measures that are updated by Jeffrey conditioning. This generalizes a number of different merging results in the literature. (...) We also show that such sets converge to a shared, maximally informed opinion. Convergence to a maximally informed opinion is a (weak) Jeffrey conditioning analogue of Bayesian “convergence to the truth” for conditional probabilities. Finally, we demonstrate the philosophical significance of our study by detailing applications to the topics of dynamic coherence, imprecise probabilities, and probabilistic opinion pooling. (shrink)
