La plupart des projets d’architectures cognitives dans les sciences cognitives et des explications des processus cérébraux dans les neurosciences interprètent l’esprit/cerveau comme réactif : le processus est déclenché par un stimulus et se termine par une réponse.

This paper studies a sender-receiver game in which both players want the receiver to choose the state-optimal action. Before observing the state, the sender observes a “contextual signal,” a payoff-irrelevant signal that correlates with states and is imperfectly shared with the receiver. Once the sender observes the state, the sender sends a message to the receiver, incurring a small messaging cost. It is shown that there is no miscommunication in any efficient equilibrium if the messaging cost is uniform or contextual (...) information is poorly shared between players. However, if the messaging costs are different between some messages, and contextual information can affect the probability ranking of states and is shared reasonably well, any efficient equilibrium that favors the sender exhibits miscommunication. Furthermore, the messages that cause miscommunication can be coarse or ambiguous, depending on how well players share contextual information. (shrink)

We expose some representations and practices related to the natural environment among Nahua peasants in a village located at the western boundary of Puebla and Guerrero states, in Mexico. Information was obtained by individual interviews and focal groups' work, following an open guide with ecological items considered as rooted in Mesoamerican cultures. The use of some local, vegetal resources, and the local perception of changes, mainly in the water availability, is documented. Survival strategies involve ancestral representations and material products, (...) and entail a high grade of pragmatism. “Natural environment” is framed in a local culture that involves relational and sacred dimensions, usually omitted in other approaches. Hence, for the Temalac peasants, there is no dissection, at an operative level, between “natural facts” and personal or social ones, being these often considered as determinant for the quality and accessibility of resources and weather conditions. We discuss the challenge for these elements posed by a growing migration rate and an increasing external influence. (shrink)

The claims that “The brain processes information” or “Cognition is information processing” are accepted as truisms in cognitive science. However, it is unclear how to evaluate such claims absent a specification of “information” as it is used by neurocognitive theories. The aim of this article is, thus, to identify the key features of information that information-based neurocognitive theories posit. A systematic identification of these features can reveal the explanatory role that information plays in specific (...) neurocognitive theories, and can, therefore, be both theoretically and practically important. These features can be used, in turn, as desiderata against which candidate theories of information may be evaluated. After discussing some characteristics of explanation in cognitive science and their implications for “information”, three notions are briefly introduced: natural, sensory, and endogenous information. Subsequently, six desiderata are identified and defended based on cognitive scientific practices. The global workspace theory of consciousness is then used as a specific case study that arguably posits either five or six corresponding features of information. (shrink)

Through a series of examples, we illustrate some important drawbacks that the action model logic framework suffers from in its ability to represent the dynamics of information updates. We argue that these problems stem from the fact that the action model, a central construct designed to encode agents’ uncertainty about actions, is itself effectively common knowledge amongst the agents. In response to these difficulties, we motivate and propose an alternative semantics that avoids them by endogenizing the action model. We (...) discuss the relationship between this new framework and action model logic, and provide a sound and complete axiomatization of several new logics that naturally arise. (shrink)

Can we build endogenous expectations about the locus of occurrence of a target without being able to describe them? Participants performed cue–target detection tasks with different proportions of valid and invalid trials, without being informed of these proportions, and demonstrated typical endogenous effects. About half were subsequently able to correctly describe the cue–target relationships . However, even non-verbalizer participants showed endogenous orienting with peripheral cues , not depending solely on practice . Explicit instructions did not bring about (...) dramatic advantages in performance .With central symbolic cues, only verbalizers showed reliable endogenous effects . We concluded that endogenous orienting with peripheral cues can occur independently of participants developing explicit hypotheses about the cue–target relationships. (shrink)

Contemporary globalization is largely shaped by the predominant position and strength of the United States, and the concept of globalization is cast upon the polity and social aspects of P.R. China after Reform and Opening. Globalization, though substantially varied in a modern scene, is not without historical and cultural roots. The future holds anew, whereas newly arisen pieces of knowledge and information shed new light on the past, the blood and violence of the political progress on the Chinese soil. (...) This paper digs into the interactive aspect of the Chinese civilization with Western Civilization, and an empirical understanding on the evolvement of the country / nation to the recent shaping, with implication of which might change the dynamic of the Asian area after the global power politics whereof after World War II.

This paper empirically investigates the interaction between repeated transactions and endogenous contractual incompleteness. We design an indefinitely repeated games experiment between identifiable players. In this experiment, the probability of continuation and the level of shared information vary over the treatments. The level of contractual completeness is decided by participants at each period. Our results show that past interactions are a stronger determinant of the level of investment in contractual completeness than the perspective of future business.

Using PitchBook’s private equity database of 4548 PE funds from 42 countries for the 2000 to 2012 period, we find that higher reporting frequency is associated with lower information asymmetry in performance reports from general partners to limited partners. We also find that endowments are systematically associated with less reported unrealized returns as a percentage of total returns generated from GPs. Moreover, endowments receive more performance reports from their PE funds, implying more stringent governance. These findings persist after controlling (...) for various institutional and GP characteristics and are robust to several adjustments for endogeneity concerns. This study also contributes to the finance, accounting, and business ethics literature on financial reporting quality. (shrink)

A fundamental aspect of biological systems is their spatial organization. In development, regeneration and repair, directional signals are necessary for the proper placement of the components of the organism. Likewise, pathogens that invade other organisms rely on directional signals to target vulnerable areas. It is widely understood that chemical gradients are important directional signals in living systems. Less well recognized are electrical fields, which can also provide directional information. Small, steady electrical fields can directly guide cell movement and growth (...) and can generate chemical gradients of charged macromolecules against the leveling action of diffusion. At the site of a lesion in an ion‐transporting epithelium, for example, a substantial electrical field is instantly generated and may extend over many cell diameters. There are numerous other situations in which relatively long‐range electrical fields have been shown to exist naturally. Recently, there has been substantial progress in identifying specific processes that are controlled, to some extent, by these endogenous electrical fields. This review highlights these recent data and discusses possible mechanisms by which the fields might affect biological processes. BioEssays 25:759–766, 2003. © 2003 Wiley Periodicals, Inc. (shrink)

One of the most prominent social influences on human decision making is conformity, which is even more prominent when the perceptual information is ambiguous. The Bayes optimal solution to this problem entails weighting the relative reliability of cognitive information and perceptual signals in constructing the percept from self‐sourced/endogenous and social sources, respectively. The current study investigated whether humans integrate the statistics (i.e., mean and variance) of endogenous perceptual and social information in a Bayes optimal way (...) while estimating numerosities. Our results demonstrated adjustment of initial estimations toward group means only when group estimations were more reliable (or “certain”), compared to participants’ endogenous metric uncertainty. Our results support Bayes optimal social conformity while also pointing to an implicit form of metacognition. (shrink)

This paper clarifies why editors of academic journals should share with their referees the information about the number of referees they consult and the decision rule they apply. Our analysis also rationalizes the common questionable phenomenon of editors who seem to distort the yes or no recommendations of their referees. The editors request a recommendation of whether to accept or reject the paper as well as an assessment of the paper. The editors need the complete reports to make the (...) appropriate correction of the referees' final recommendations. (shrink)

The search for knowledge is a fact of any human society in the quest for development, as it is in the nature of human species to do so. This is geared towards humanisation of the society in the attainment of positive social change, which cannot be realised without adequate and informed knowledge from the culture of the people. This form of knowledge is seen from the identity of the people, focusing on the social change of their society. The creation of (...) a national consciousness is a crucial component of the society as it presupposes identity, seen as the heart of any culture that motivates the collective common goal of the people. This paper, using the analytic methodology in the philosophical discipline, therefore argues that the acceptance of cultural knowledge from the platform of its identity in the quest for development in Africa is a conditio sine qua non.

In this article, we propose that giving in cash and non-cash differ in their relation with the giving firm’s future corporate financial performance and only cash giving is associated with future CFP. Using a novel dataset from ASSET4 that differentiates corporate giving over a sample period of 2002–2012, we examine three competing hypotheses: agency cost hypothesis that cash giving reflects agency cost and destroys value for shareholders, investment hypothesis that cash giving is an investment by management that aims for better (...) future return, and information hypothesis that cash giving has informational value to shareholders as cash is a critical resource at a firm and giving is a decision by managers who are insiders. We find that indeed, only cash giving is positively associated with future CFP and firm value, measured by Fama–French five-factor abnormal risk-adjusted stock returns, future return on assets, and Tobin’s Q. In addition, we find that the positive association exists only between excess, i.e., unexpected, but not expected cash giving and future CFP. Our empirical findings support the information hypothesis, but neither the agency hypothesis nor the investment hypothesis, and are robust to a number of endogeneity tests, including orthogonalized cash giving, instrumental variable regression using geography-based instruments, and propensity score matching. Furthermore, we show that the positive association between future CFP and unexpected cash giving is only pronounced at firms with good governance and relatively higher sales growth where agency problems are less likely, and at firms with no alternative mechanisms to demonstrate the strength of cash flow. Additionally, we do not find evidence that suggests in-kind giving to possess any informational value. (shrink)

In this study, we examine the empirical association between corporate social responsibility and information asymmetry by investigating their simultaneous and endogenous effects. Employing an extensive U.S. sample, we find an inverse association between CSR engagement and the proxies of information asymmetry after controlling for various firm characteristics. The results hold using 2SLS considering the reverse side of information asymmetry influencing CSR activities. The results also hold after mitigating endogeneity based on the dynamic panel system generalized method (...) of moment. Furthermore, the CSR–information asymmetry relation is amplified in high-risk firms due to managers’ efforts to build a good reputation. Last, we find that CSR engagement is inversely associated with reputational risk measure and lower predicted value of reputational risk is positively associated with lower information asymmetry measures. We interpret these results as supporting the stakeholder theory-based, reputation-building explanation that considers CSR engagement as a vehicle to build and maintain firm reputation thereby enhancing the information environment.

The most disturbing aspects of the growth of underground economies are the interrelated problems of unreported and unrecorded income. A large and growing underground economy can thwart fiscal efforts to establish budget balance and may significantly undermine the veracity of a nation's economic information system. The notion that economic information is itself endogenous raises the possibility that at least part of the economic malaise observed in most Western nations during the past two decades is essentially the result (...) of a statistical illusion. The essays in this 1989 volume examine the problems of defining, measuring and understanding the implications of the underground economies that have emerged in many of the world's developed nations. Empirical chapters examine the conceptual problems of how to measure a phenomenon that attempts to defy detection. Alternative measurement procedures are evaluated. Specific studies are included for the United States, the Netherlands, the United Kingdom, Germany, Sweden, Italy, Norway, Canada, France, the Soviet Union and Hungary. (shrink)

Using data from the China Family Panel Studies, this paper investigates the effects of Internet use on residents’ risk attitudes. Both Generalized Ordered Logit Model and Logit model are used to identify the effects of Internet use. The results reveal an association between Internet use and increases in both subjective and objective risk preferences that remains even after we adjust for possible endogeneity. The heterogeneity analysis also reveals that these impacts are different among groups with different reasons for Internet use (...) and different personal characteristics. Our study expands the research on the effects of Internet on people’s concepts from the micro perspective and suggests that while promoting the application of information technology we should also pay attention to the individual characteristics of residents so that we can better share the “digital dividend” brought by the popularization of information technology in the whole society.

The sex ratio at birth in China exhibits a major occurrence of “missing women” due to the high son preference in Chinese culture. Clearly, the large gender discrepancy in China can be explained not only by ethical, moral, or social fairness theories but also by the economic benefits of women's particular abilities, experiences, and talents. This article examines the influence of female chief financial officers on information disclosure violations in order to highlight women's positive contributions. Our data imply that (...) having a female CFO can dramatically lower the number of companies that fail to disclose information. The results are strong after controlling endogeneity with propensity score matching, Heckman's two-stage self-selection model, and CFO change, as well as controlling the gender of the chairman and chief executive officer, utilizing different study periods, and using exogenous shock. We further examined the moderate effects of CFO power and external monitoring, and we found that CFO power magnifies the negative effect of female CFO on violations; the more the power, the more the negative effect of female CFO on violations. We also found that when the firm has effective external monitoring, there are fewer future infractions of information disclosure. (shrink)

Alternative non‐B‐DNA conformations formed under physiological conditions by sequences called flipons include left‐handed Z‐DNA, three‐stranded triplexes, and four‐stranded i‐motifs and quadruplexes. These conformations accumulate and release energy to enable the local assembly of cellular machines in a context specific manner. In these transactions, nucleosomes store power, serving like rechargeable batteries, while flipons smooth energy flows from source to sink by acting as capacitors or resistors. Here, I review the known biological roles for flipons. I present recent and unequivocal findings showing (...) how innate immune responses are regulated by Z‐flipons that identify endogenous RNAs as self. Evidence is also presented supporting important roles for other flipon classes. In these examples, the dynamic exchange of energy between flipons and nucleosomes enables rapid switching of genetic programs without altering flipon sequence. The increased phenotypic diversity enabled by flipons drives their natural selection, with adaptations evolving faster than is possible by codon mutation alone. (shrink)
