I study a market model in which profit-maximizing firms compete in multidimensional pricing strategies over a consumer, who is limited in his ability to grasp such complicated objects and therefore uses a sampling procedure to evaluate them. Firms respond to increased competition with an increased effort to obfuscate, rather than with more competitive pricing. As a result, consumer welfare is not enhanced and may even deteriorate. Specifically, when firms control both the price and the quality of each dimension, and there (...) are diminishing returns to quality, increased competition implies an efficiency loss which is entirely borne by consumers. KEYWORDS. Bounded rationality, industrial organization, multi-dimensional pricing, law of small numbers, market exploitation, obfuscation. (shrink)

In this short note I speculate about the various ways in which the study of neurological aspects of decision making could be fruitful for economic modelling.

An observer attempts to infer the unobserved ranking of two ideal objects, A and B, from observed rankings in which these objects are `accompanied' by `noise' components, C and D. In the first ranking, A is accompanied by C and B is accompanied by D, while in the second ranking, A is accompanied by D and B is accompanied by C. In both rankings, noisy-A is ranked above noisy-B. The observer infers that ideal-A is ranked above ideal-B. This commonly used (...) inference rule is formalized for the case in which A,B,C,D are sets. Let X be a finite set and let be a linear ordering on 2X. The following condition is imposed on . For every quadruple (A,B,C,D)∈Y, where Y is some domain in (2X)4, if and , then . The implications and interpretation of this condition for various domains Y are discussed. (shrink)

In this short article I proudly present ARSECOG: The Ariel Rubinstein Seminar Comment Generator. This is an AI program in the style of ELIZA. However, instead of simulating a psychotherapist, it simulates the eminent economist Ariel Rubinstein. Prof. Rubinstein is renowned for his insightful and penetrating comments during research seminars. I am sure many of us, who envy his capabilities in this department, would find a program such as ARSECOG quite useful.

With a few yet increasing number of exceptions, the cognitive sciences enthusiastically endorsed the idea that there are basic facial expressions of emotions that are created by specific configurations of facial muscles. We review evidence that suggests an inherent role for context in emotion perception. Context does not merely change emotion perception at the edges; it leads to radical categorical changes. The reviewed findings suggest that configurations of facial muscles are inherently ambiguous, and they call for a different approach towards (...) the understanding of facial expressions of emotions. Prices of sticking with the modal view, and advantages of an expanded view, are succinctly reviewed. (shrink)

An amplitude controllable hyperjerk system is constructed for chaos producing by introducing a nonlinear factor of memristor. In this case, the amplitude control is realized from a single coefficient in the memristor. The hyperjerk system has a line of equilibria and also shows extreme multistability indicated by the initial value-associated bifurcation diagram. FPGA-based circuit realization is also given for physical verification. Finally, the proposed memristive hyperjerk system is successfully predicted with artificial neural networks for AI based engineering applications.

I argue that, contrary to some critics, the notion of conscious experience is a good candidate for denoting a distinct and scientifically interesting phenomenon in the brain. I base this claim mainly on an analysis of neuropsychological data concerning deficits resulting from various types of brain damage as well as some additional supporting empirical evidence. These data strongly point to the hypothesis that conscious experience expresses information that is available for global, integrated, and flexible behavior.

This ambitious book looks 'behind the model' to reveal how economists use formal models to generate insights into the economy. Drawing on recent work in the philosophy of science and economic methodology, the book presents a novel framework for understanding the logic of economic modeling. It also reveals the ways in which economic models can mislead rather than illuminate. Importantly, the book goes beyond purely negative critique, proposing a concrete program of methodological reform to better equip economists to detect potential (...) mismatches between their models and the targets of their inquiry. Ranging across economics, philosophy, and social science methods, and drawing on a variety of examples, including the recent financial crisis, Behind the Model will be of interest to anyone who has wondered how economics works - and why it sometimes fails so spectacularly.

The modern ethical framework demands informed consent for research participation that includes disclosure of material information, as well as alternatives. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic (COVID-19) results in illness that often involves rapid deterioration. Despite the urgent need to find therapy, obtaining informed consent for COVID-19 research is needed. The current pandemic presents three types of challenges for investigators faced with obtaining informed consent for research participation: (1) uncertainty over key information to informed consent, (2) time (...) and pressure constraints, and (3) obligations regarding disclosure of new alternative therapies and re-consent. To mitigate consenting challenges, primary investigators need to work together to jointly promote urgent care and research into COVID-19. Actions they can take include (1) prior plan addressing ways to incorporate clinical research into clinical practice in emergency, (2) consider patients vulnerable with early deliberation on the consent process, (3) seek Legally Authorized Representatives (LARs), (4) create a collaborative research teams, (5) aim to consent once, despite evolving information during the pandemic, and (6) aim to match patients to a trial that will most benefit them. The COVID-19 pandemic both exacerbates existing challenges and raises unique obstacles for consent that require forethought and mindfulness to overcome. While research teams and clinician-investigators will need to be sensitive to their own contexts and adapt solutions accordingly, they can meet the challenge of obtaining genuinely informed consent during the current pandemic.

Remote state preparation is generation of a desired state by a remote observer. In spite of causality, it is well known, according to the Reeh–Schlieder theorem, that it is possible for relativistic quantum field theories, and a “physical” process achieving this task, involving superoscillatory functions, has recently been introduced. In this work we deal with non-relativistic fields, and show that remote state preparation is also possible for them, hence obtaining a Reeh–Schlieder-like result for general fields. Interestingly, in the nonrelativistic case, (...) the process may rely on completely different resources than the ones used in the relativistic case. (shrink)

This paper presents an extended version of the Quantified Argument Calculus (Quarc). Quarc is a logic comparable to the first-order predicate calculus. It employs several nonstandard syntactic and semantic devices, which bring it closer to natural language in several respects. Most notably, quantifiers in this logic are attached to one-place predicates; the resulting quantified constructions are then allowed to occupy the argument places of predicates. The version presented here is capable of straightforwardly translating natural-language sentences involving defining clauses. A three-valued, (...) model-theoretic semantics for Quarc is presented. Interpretations in this semantics are not equipped with domains of quantification: they are just interpretation functions. This reflects the analysis of natural-language quantification on which Quarc is based. A proof system is presented, and a completeness result is obtained. The logic presented here is capable of straightforward translation of the classical first-order predicate calculus, the translation preserving truth values as well as entailment. The first-order predicate calculus and its devices of quantification can be seen as resulting from Quarc on certain semantic and syntactic restrictions, akin to simplifying assumptions. An analogous, straightforward translation of Quarc into the first-order predicate calculus is impossible. (shrink)

. In his writings, Francis Bacon emphasized the interrelatedness between the migration of people and knowledge, arguing that Europeans of his time had surpassed the greatest civilizations because of their ability to traverse the world freely. Concentrating on Spanish observers who investigated New Spain’s flora, this article bridges theory and practice by examining the Iberian roots of Bacon’s views. The article examines scientific approaches for acquiring bioknowledge by Iberians who specialized in European medicine, including Francisco Hernández, Juan de Cárdenas and (...) Francisco Ximénez. While the article recognizes the contribution of travellers and expatriates to Spain’s bioprospecting project, it also points to the ways in which the limitations of the transfer of botanical information was acknowledged and discusses its meaning. By presenting the complexities in the communication of knowledge, I argue, naturalists in the colonies could highlight their unique vantage point in relation to “armchair” specialists in the metropole.

Much has been written about the global convergence on constitutional supremacy. Yet, a closer look suggests that while constitutional convergence trends are undoubtedly extensive and readily visible, expressions of constitutional resistance or defiance may in fact be regaining ground worldwide. This may point to a paradox embedded in global constitutionalism: the more expansive constitutional convergence trends are, the greater the likelihood of dissent and resistance are. In this article, I chart the contours of three aversive responses to constitutional convergence: neo-secessionism, (...) nullification, and deference to local authority, and draw on an array of comparative examples to illustrate the distinct logic and characteristics of each of these responses. Taken together, these increasingly common expressions of defiance provide ample evidence that global constitutionalism is not the only game in town. Neo-secessionism, nullification, and other forms of constitutional dissent and “opting out” may thus be viewed as a reaction against the centralization of authority and the decline of the local in an increasingly—constitutionally and otherwise—universalized reality.

This article examines whether the likelihood and amount of firm charitable giving in response to catastrophic events are related to firm advertising intensity, and whether industry competition level moderates this relationship. Using data on Chinese firms’ philanthropic response to the 2008 Sichuan earthquake, we find that firm advertising intensity is positively associated with both the probability and the amount of corporate giving. The results also indicate that this positive advertising intensity-philanthropic giving relationship is stronger in competitive industries, and firms in (...) competitive industries are more likely to donate. This study thus provides evidence suggesting that even in the wake of catastrophic events, corporate philanthropic giving is strategic. (shrink)

The 19th century saw the rise of Biblical Criticism in German universities, culminating in Wellhausen s radical revision of the history of biblical times and religion. For German-Jewish intellectuals, the academic discipline promised emancipation from traditional Christian readings of Scripture but at the same time suffered from what was perceived as anti-Jewish bias, this time in scholarly robes. Reclaiming the Hebrew Bible describes the German-Jewish strategies to cope with Biblical Criticism varying from an enthusiastic welcome, through modified adoption, to resolute (...) rejection.".

Working Memory plays a crucial role in many high-level cognitive processes . The prevalent view holds that active components of WM are predominantly intentional and conscious. This conception is oftentimes expressed explicitly, but it is best reflected in the nature of major WM tasks: All of them are blatantly explicit. We developed two new WM paradigms that allow for an examination of the role of conscious awareness in WM. Results from five studies show that WM can operate unintentionally and outside (...) of conscious awareness, thus suggesting that the current view should be expanded to include implicit WM. (shrink)

This article examines whether the charitable giving amount and likelihood of firm response to catastrophic events relate to firms’ ownership type using a unique dataset of listed firms in China, where state ownership is still prevalent. Based on the data of Chinese firms’ response to the 2008 Sichuan earthquake, we find that the extent of corporate contributions for state-owned firms following this disaster is less than that for private firms. State-owned firms are also less likely to respond in␣this disaster compared (...) to private firms. The results also␣reveal that firm size, profitability, geography, cash resource available, and leverage affect firms’ philanthropic disaster response behavior in China. (shrink)

Looking at Soyoung Kim’s Exile Trilogy, three documentaries centering on ethnic Koreans in Central Asia and specifically the use of archival footages and soundtracks in Sound of Nomad, Arirang, this article considers Kim’s works an organic contribution to the image archive of/about/by the global Korean diaspora while seeking to interrogate the politics of “retro” by turning to what Catherine Russell has approached as “archiveology.” Foregrounding the representation of the transgenerational divas from the “Arirang Ensemble” of the Koryo Theater in Almaty, (...) Kazakhstan, this piece highlights how the divas’ personal stories reconstructed via images, oral accounts, sound recordings, and so forth need to be grasped as an assemblage of affective flows that has complicated the teleological narrative about the Korean diaspora and problematized the Soviet state’s ideocultural representations of the Koryo people.

This study investigated inverse preference effects in L2 structural priming of English relative clauses and their potential influences on subsequent learning of target structures. One hundred fourteen Chinese learners of English at a low-to-intermediate proficiency level participated in a structural priming experiment with a pretest-posttest design. The experimental group underwent a priming task in which they orally produced syntactic structures immediately after viewing English object or passive relative clauses as primes, whereas the control group only read sentences unrelated to English (...) relative clauses. A grammaticality judgment task and a sentence completion task were used to measure the inverse preference effect and its subsequent effects on L2 learning. The results showed the presence of structural priming and inverse preference effects in immediate production, which extended to subsequent learning of L2. In subsequent grammaticality judgments and production, L2 learners performed better with English object relative clauses than with English passive relative clauses in comparison with the pretest. The results are discussed in terms of the structural frequency in both L1 and L2 as well as the implicit learning mechanisms of structural priming. (shrink)
