Since sending explicit messages can be costly, people often utilize “what is not said,” i.e., informative silence, to economize communication. This paper studies the efficient communication rule, which is fully informative while minimizing the use of explicit messages, in cooperative environments. It is shown that when the notion of context is defined as the finest mutually self-evident event that contains the current state, the efficient use of informative silence exhibits the defining property of indexicals in natural languages. While the efficient (...) use of silence could be complex, it is also found that the efficient use of silence can be as “simple” as the use of indexicals in natural languages if and only if the information structure satisfies some centrality and dominance properties.

We have been left with a big challenge, to articulate consciousness and also to prove it in an artificial agent against a biological standard. After introducing Boltuc’s h-consciousness in the last paper, we briefly reviewed some salient neurology in order to sketch less of a standard than a series of targets for artificial consciousness, “most-consciousness” and “myth-consciousness.” With these targets on the horizon, we began reviewing the research program pursued by Jun Tani and colleagues in the isolation of the (...) formal dynamics essential to either. In this paper, we describe in detail Tani’s research program, in order to make the clearest case for artificial consciousness in these systems. In the next paper, the third in the series, we will return to Boltuc’s naturalistic non-reductionism in light of the neurorobotics models introduced (alongside some others), and evaluate them more completely.

When an agent’s motivation is sensitive to how his supervisor thinks about the agent’s competence, the supervisor has to take into account both informational and expressive contents of her message to the agent. This paper shows that the supervisor can credibly express her trust in the agent’s ability only by being un- clear about what to do. Suggesting what to do, i.e., “directives,” could reveal the supervisor’s “distrust” and reduce the agent’s equilibrium effort level even though it provides useful information (...) about the decision environment. There is also an equilibrium in which directives are neutral in expressive content. However, it is shown that neologism proofness favors equilibria in which directives are double- edged swords.

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)

This third paper locates the synthetic neurorobotics research reviewed in the second paper in terms of themes introduced in the first paper. It begins with biological non-reductionism as understood by Searle. It emphasizes the role of synthetic neurorobotics studies in accessing the dynamic structure essential to consciousness with a focus on system criticality and self, develops a distinction between simulated and formal consciousness based on this emphasis, reviews Tani and colleagues' work in light of this distinction, and ends by (...) forecasting the increasing importance of synthetic neurorobotics studies for cognitive science and philosophy of mind going forward, finally in regards to most- and myth-consciousness.

A decision maker (DM) selects a project from a set of alternatives with uncertain productivity. After the choice, she observes a signal about productivity and decides how much effort to put in. This paper analyzes the optimal decision problem of the DM who rationally filters information to deal with her post-decision cognitive dissonance. It is shown that the optimal effort level for a project can be affected by unchosen projects in her choice set, and the nature of the choice set-dependence (...) is determined by the signal structure. Some comparative statics of choice set-dependence is also provided. Finally, based on the results, the optimal choice set design is also explored. This paper offers a simple framework to explain the experimental finding in psychology that people’s effort level for a project can be enhanced when the project is chosen by themselves rather than by others.

Direct neurological and especially imaging-driven investigations into the structures essential to naturally occurring cognitive systems in their development and operation have motivated broadening interest in the potential for artificial consciousness modeled on these systems. This first paper in a series of three begins with a brief review of Boltuc’s (2009) “brain-based” thesis on the prospect of artificial consciousness, focusing on his formulation of h-consciousness. We then explore some of the implications of brain research on the structure of consciousness, finding limitations (...) in biological approaches to the study of consciousness. Looking past these limitations, we introduce research in artificial consciousness designed to test for the emergence of consciousness, a phenomenon beyond the purview of the study of existing biological systems.

Zájem současné sociologie a dalších společenských věd o výzkumy spokojenosti a štěstí zatemňuje skutečnost, že původně právě sociologie chtěla „štěstí" poskytovat a nahrazovat tak náboženské přístupy ke světu. Tento implicitně nábo- ženský charakter je patrný i v rané české sociologii v dílech prvních propagátorů sociologie, jako byl především Emanuel Makovička, a později u některých následovníků a epigonů T. G. Masaryka, v meziválečném období zejména u Ladislava Kunteho, R. I. Malého, Alexandra Sommera-Batěka, Jindřicha Fleischnera a Jana Duška. Z hlediska vývoje české (...) sociologie šlo o zcela okrajové postavy, ačkoli mnohé z nich vynikly v jiných oblastech, jako celek jsou nicméně vyjádřením jednoho z aspektů dobových teoretických úvah o společnosti, jejím uspořádání a vývoji, na který by nemělo být zapomínáno. Zatímco T. G. Masaryka a pozdější akademické sociology „omezoval" vědecký charakter jejich práce, a i pokud směřovali k sociálnímu reformismu, oddělovali jej od teoretické sociologie, „sociologie vedoucí ke štěstí" nalezla plné uplatnění ve vizích a ambiciózních projek- tech těchto amatérských takésociologů - třebaže skončily faktickými nezdary nebo ani nedošly praktického naplnění, ostatně stejně jako v případě jejich pravzoru, Comtova pozitivistického apoštolátu.

Florentin Smarandache është një nga shkrimtarët më të talentuar në letërsinë rumune të diasporës. Dashuria e saj për librin ripërtërihet gjithmonë, duke arrdhur tani para lexuesve tanë me një libër të ri të ilustruar dhe të destinuar për lexuesit më të vegjël. Kjo është një befasi e re me disa tregime të bukura për shijen e fëmijëve të ditëve tona. Florentin Smarandache është një adhurues i leximit, një krijesë frymëzimesh të zjarrta për të cilin leximi është bërë një mënyrë (...) e vërtetë jetese, një lloj zgjatje e qenies së tij. Nuk e dimë saktësisht se kur i imagjinonte krijimet e para, por e dimë se ai mësoi të lexonte e të shkruante, me hirin hyjnor, përpara se të hynte në shkollë. Ai ka qenë I magjepsur që atëherë nga fuqia e fjalës, nga mënyra se si u bashkuan për të formuar fjalë dhe nga kuptimet dhe fuqia që mund të sillnin. Pastaj e di se ai mezi priste të huazonte libra nga biblioteka e shkollës dhe se hyri në atë dhomë që dukej e madhe me shumë emocion. Florentini lexonte libër pas libri, duke dashur gjithmonë më shumë, duke pasur parasysh se nuk kalonte mjaftueshëm kohë në shoqërinë e miqve më të mirë që kishte pasur ndonjëherë. Në momentin që hap një libër të ilustruar për fëmijë, hyn në një botë tjetër, ndryshe nga ajo e të rriturve. Jeni të zhytur nga bukuria e botëve të pikturuara me ngjyra nga krijues dhe ilustrues të talentuar, pastaj takoni heronj fantastikë me të cilët gjithçka është e mundur. Autori gjithmonë i ka dashur fëmijët, poezitë dhe tregimet për të vegjlit, sepse librat për fëmijë e kanë magjepsur. Nëse e pyesni veten se si ka nisur të shkruajë, për krimtarin Florentin Smarandache, historia është shumë e bukur. Kur fëmijët filluan të shkonin në shkollë, kishin nevojë për përralla dhe poezi për raste të ndryshme, për vjeshtë, për Vitin e Ri, për dimër, për pranverë, dhe kështu ai filloi të shkruante poezi në letër, ku fëmijët ishin lexuesit dhe kritikët e saj të parë letrarë.
