Abstract:

In this paper, I introduce the emerging theory of judgment aggregation as a framework for studying institutional design in social epistemology. When a group or collective organization is given an epistemic task, its performance may depend on its ‘aggregation procedure’, i.e. its mechanism for aggregating the group members' individual beliefs or judgments into corresponding collective beliefs or judgments endorsed by the group as a whole. I argue that a group's aggregation procedure plays an important role in determining whether the group can meet two challenges: the ‘rationality challenge’ and the ‘knowledge challenge’. The rationality challenge arises when a group is required to endorse consistent beliefs or judgments; the knowledge challenge arises when the group's beliefs or judgments are required to track certain truths. My discussion seeks to identify those properties of an aggregation procedure that affect a group's success at meeting each of the two challenges.

Abstract:

AbstractThese brief remarks highlight three aspects of Christian List and Philip Pettit's Group Agency: The Possibility, Design, and Status of Corporate Agents that illustrate its constructivist nature: (i) its stress on the discursive dilemma as a primary challenge to group rationality and reasoning; (ii) its general though qualified support for premise-based decision-making as the preferred way to cope with the problems of judgment aggregation; and (iii) its account of rational agency and moral responsibility. The essay contrasts List and Pettit's constructivist analysis of group rationality with an ecological approach, inspired by social theorists such as F A. Hayek, Vernon L. Smith and Gerd Gigerenzer.

Abstract:

Social epistemology is a many-splendored subject. Different theorists adopt different approaches and the options are quite diverse, often orthogonal to one another. The approach I favor is to examine social practices in terms of their impact on knowledge acquisition (Goldman 1999). This has at least two virtues: it displays continuity with traditional epistemology, which historically focuses on knowledge, and it intersects with the concerns of practical life, which are pervasively affected by what people know or don't know. In making this choice, I am not blind to the allure of alternative approaches. In this paper I explain and motivate the knowledge-centered approach by contrasting it with a newly emerging alternative that has a definite appeal of its own. According to this alternative, the chief dimension of social epistemological interest would be rationality rather than knowledge.

Abstract:

BackgroundEmpirical studies of rationality (syllogisms) in patients with schizophrenia have obtained different results. One study found that patients reason more logically if the syllogism is presented through an unusual content.AimsTo explore syllogism-based rationality in schizophrenia.MethodThirty-eight first-admitted patients with schizophrenia and 38 healthy controls solved 29 syllogisms that varied in presentation content (ordinary v. unusual) and validity (valid v. invalid). Statistical tests were made of unadjusted and adjusted group differences in models adjusting for intelligence and neuropsychological test performance.ResultsControls outperformed patients on all syllogism types, but the difference between the two groups was only significant for valid syllogisms presented with unusual content. However, when adjusting for intelligence and neuropsychological test performance, all group differences became non-significant.ConclusionsWhen taking intelligence and neuropsychological performance into account, patients with schizophrenia and controls perform similarly on syllogism tests of rationality.

Abstract:

Intergroup conflicts generally involve conflicts of interests within the competing groups as well. This article outlines a taxonomy of games, called team games, which incorporates the intragroup and intergroup levels of conflict. Its aims are to provide a coherent framework for analyzing the prototypical problems of cooperation and competition that arise within and between groups, and to review an extensive research program that has used this framework to study individual and group behavior in the laboratory. Depending on the game's payoff structure, contradictions or conflicts are created among the rational choices at the individual, group, and collective levels—a generalization of the contradiction between individual and collective rationality occurring in the traditional mixed-motive games. These contradictions are studied so as to identify the theoretical and behavioral conditions that determine which level of rationality prevails.

Abstract:

Abstract Rationality is a fundamental pillar of Economics. It is however unclear if this assumption holds when decisions are made under stress. To answer this question, we design two laboratory experiments where we exogenously induce physiological stress in participants and test the consistency of their choices with economic rationality. In both experiments we induce stress with the Cold Pressor test and measure economic rationality by the consistency of participants’ choices with the Generalized Axiom of Revealed Preference (GARP). In the first experiment, participants delay the decision-making task for 20 min until the cortisol level peaks. We find significant differences in cortisol levels between the stressed group and the placebo group which, however, do not affect the consistency of choices with GARP. In a second experiment, we study the immediate effect of the stressor on rationality. Overall, results from the second experiment confirm that rationality is not impaired by the stressor. If anything, we observe that compared to the placebo group, participants are more consistent with rationality immediately after the stressor. Our findings provide strong empirical support for the robustness of the economic rationality assumption under physiological stress.

Abstract:

AbstractSuppose we are given a finite-dimensional vector space V equipped with an F-rational action of a linearly algebraic group G, with F a characteristic zero field. We conjecture the following: to each vector v ∈ V(F) there corresponds a canonical G(F)-orbit of semisimple vectors of V. In the case of the adjoint action, this orbit is the G(F)-orbit of the semisimple part of v, so this conjecture can be considered a generalization of the Jordan decomposition. We prove some cases of the conjecture.

Abstract:

The article discusses the compatibility of particular rational actions at the individual level with the rationality as such at the collective one. The issue arises in decision-making collisions by several individuals, when the results of a possible rational choice of an individual are restricted by interactions with other actors. Such cases of interaction are found in the economic theory, political science, sociology, management and other areas of science related to a person and a group of people. The article examines the social dilemmas that are obvious when all individuals in a social group behave as «rational maximizers of utility» what makes it difficult to come to mutual agreement and coordinate their actions. In respect to the «tragedy of the common» dilemma, the author discusses ways of overcoming the incompatibility for individual and collective rationality within the framework of a new institutional policy, as a new direction of science in the public resources management.

Abstract:

To overcome the shortcomings in traditional approaches such as bad satisfaction, bad effectiveness and so on, three key bounded rationality assumptions are proposed firstly, i.e., risky preference is invariable, decision cost is existing, and group cognitive ability is only unbounded rational. After that, an efficient prospect deriving model is presented by data envelopment analysis with assurance region to derive efficient alternatives from inadequate decision information. The presented model is able to reflect the subjective risky preferences of group members and derive efficient alternatives under the premise of existing acquisition costs, and thus it can make the satisfactory and effective decision.

Abstract:

Abstract This article provides a selective overview of the economic study of terrorism. After defining key terms - terrorists’ rationality, domestic and transnational terrorism, and counterterrorism measures, we present two models of terrorists’ behavior. The first model depicts a choice-theoretic model of how terrorist groups allocate their resources among attack modes or target types. The second model is a strategic analysis involving the terrorist group and a targeted government. Extensions to these base models are then discussed. The latter part of the article investigates the dilemma that terrorism poses to liberal democracies. We conclude by examining myriad externalities associated with counterterrorism measures.

Abstract:

AbstractInKnowledge in a Social World, Alvin Goldman presents a framework to quantify the epistemic effects that various policies, procedures, and behaviors can have on a group of agents. In this essay, I show that the framework requires some modifications when applied to agents with credences. The required modifications carry with them an interesting consequence, namely, that any group whose members disagree can become more accurate by forming a consensus through averaging their credences. I sketch a way that this result can be used to show that individual norms of rationality and group norms of rationality can dictate conflicting behaviors for the members of some groups. I conclude by discussing how some of the assumptions used to generate the consensus result might be loosened.

Abstract:

Self-medication is simply a person's attempt to treat symptoms of illness or disease without consulting a doctor first. Self-medication also means treating all complaints about oneself with medicines purchased directly at pharmacies or drug stores on their initiative without a doctor's prescription. OTC (Over The Counter) drugs are medicines that can be purchased without a prescription, namely over-the-counter and limited over-the-counter drugs, including fever-reducing drugs, pain relievers and inflammation relievers, cough medicines, cold medicines, ulcer medicines, diarrhea medicines, and skin medicines. The use of drugs in self-medication is carried out correctly to ensure the accuracy, rationality, and safety of drug use in self-medication. This study aimed to determine the demographic data characteristics of self-medication patients, the rationality of self-medication, and the influence of patient demographic data characteristics on rationality in OTC (Over Counter) drug self-medication patients. This study used a cross-sectional method. As many as 100 respondents aged 18-60 who self-medicated OTC (Over Counter) drugs at the West Pasaman District Pharmacy were involved in this study. Data collection was carried out using a questionnaire. Data were analyzed using Statistical Product And Servicer Solution (SPSS) 23. The results of this study showed that the majority of respondents who self-medicated OTC (Over Counter) drugs were 58% women, 63% of the age group 18-60 years, the last education group was low ( SD, SMP, SMA) by 77% and the non-PNS/non-private employee group is 82%. Respondents who used self-medication rationally were quite large, namely 86%. The factor that influences self-medication is age. While gender, education, and occupation do not affect self-medication

We show that a $k$-torus is retract rational if and only if it is $p$-retract rational for every prime $p$, and that the Noether problem for retract rationality for a group of multiplicative type $G$ has an affirmative answer for $G$ if and only if the Noether problem for $p$-retract rationality for $G$ has a positive answer for all $p$. For every finite set of primes $S$ we give examples of tori that are $p$-retract rational if and only if $p\notin S$.

Abstract:

The paper is devoted to the economic analysis of rationality in the tradition of Harvey Leibenstein: the authors perceive rationality as “calculatedness” when making decisions, while the degree of this “calculatedness” is interpreted as a variable. Thus, this approach does not correspond to the generally accepted neoclassical interpretation of rationality, according to which rationality is both full and constant. The authors believe that such a neoclassical approach makes too stringent requirements for the abilities of people. In real life, people do not behave like calculating machines. The paper discusses various factors limiting the degree of rationality of individuals. One group of factors is associated with external information constraints such as the complexity and extensiveness of information, as well as the uncertainty of the future. Another group of factors is related to informal institutions. In particular, the paper states that the system of planned socialism contributes to less rationality than the system of market capitalism. Thus, in the post-socialist countries, including contemporary Russia, one should not expect a high degree of rationality of the behavior of economic entities. The paper mentions, in particular, the factors of rationality caused by informal institutions, such as the propensity to calculate, the propensity to be independent when making decisions and the propensity to set goals. The authors also believe that people who live on their own are usually more rational than people who share a common household with someone else. This assumption is verified econometrically based on data on young urban residents collected by the authors. It turned out that the behavior of people included in this database, in general, corresponds to what the authors believed.

Abstract:

Assume that K is a field, containing the full group of 4th roots of unity μ4, and char K ≠2, 3. Let G be a finite non-abelian subgroup of GL n(K) for n = 3 or n = 4. The group G induces an action on K(x1,…,xn), the rational function field of n variables over K. Consider groups represented by matrices such that in each row and column there is exactly one element from μ4 and all other elements are 0. With the aid of GAP [3] we find that there are precisely 230 such non-abelian groups in SL 4(K) and 33 in GL 3(K), up to conjugacy. We show that the fixed subfield K(x1,…,xn)G is rational (i.e. purely transcendental) over K for every such group G. We also give a positive answer to the Noether's problem for several families of groups of order m = 2a ⋅ 3b, where a ≥ 2 and b = 0, 1.

Abstract:

Backgrounds. It is very important to evaluate and assess the rationality of the use of antidiabetic drugs, especially the biguanide (metformin) group to maintain the quality and quality of diabetes mellitus drug administration so that the target of diabetes mellitus control can be optimized. This study aims to evaluate the rationality of prescribing metformin oral antidiabetic at Dr. Mohammad Hoesin General Hospital Palembang. Methods. The research design is a descriptive study using secondary data from medical records in the medical records section of Dr. Moh Hoesin Hospital Palembang. The object of research is all medical records of patients with type 2 diabetes mellitus who used metformin at RSMH Palembang in the period July 1st, 2019-July 31st, 2020, with complete medical record data and without serious comorbidities. The rationality for using metformin that was assessed in this study was the frequency of use, drug dose, route of administration, duration of administration, and drug interactions. The frequency of drug use is assessed by how many times the drug is taken in one day. Results. The most age group of patients who received a prescription for metformin were 51-60 years old and 61-70 years old with a total of 17 patients (35.4%). The majority of patients were female as much as 60.4%. Drug interactions with metformin are still quite common, although the majority are synergistic and potentiating interactions. There are still 2 cases or 4.2 percent who experience antagonistic interactions. Conclusion. The rationality for using metformin in patients with type 2 diabetes mellitus is based on the criteria for the right dose (100%), the right frequency of drug administration (100%), the right time for giving the drug (100%), the right way of giving the drug (100%), and the right drug interaction. (95.8%).

Abstract:

Screening patients or heathcare workers for Human Immunodeficiency Virus is unlikely to be cost-effective if the benefit is seen only as the prevention of infection of one group by the other within the healthcare institution. Overwhelmingly, the benefit of screening comes from interrupting the chains of infection within the ongoing epidemic in the population at large.

AbstractWe consider the problem of whether the norm one torus defined by a finite separable field extensionK/kis stably (or retract) rational overk. This has already been solved for the case whereK/kis a Galois extension. In this paper, we solve the problem for the case whereK/kis a non-Galois extension such that the Galois group of the Galois closure ofK/kis nilpotent or metacyclic.
