A number of scholars have recently defended the claim that there is a close connection between the evolutionary biological notion of fitness and the economic notion of utility: both are said to refer to an organism’s success in dealing with its environment, and both are said to play the same theoretical roles in their respective sciences. However, an analysis of two seemingly disparate but in fact structurally related phenomena—‘niche construction’ (the case where organisms change their environment to make it (...) fit to their needs) and ‘adaptive preferences’ (the case where agents change their wants to make them fit to what the world has given them)—shows that one needs to be very careful about the postulation of this sort of fitness–utility connection. Specifically, I here use the analysis of these two phenomena to establish when connecting fitness and utility is and is not possible. (shrink)

This paper presents two cognitive models that simulate the production of referring expressions in the iMAP task—a task-oriented dialog. One general model is based on Dale and Reiter’s (1995)incremental algorithm, and the other is a simple template model that has a higher correlation with the data but is specifically geared toward the properties of the iMAP task. The property of the iMAP task environment that is modeled here is that the color feature is unreliable for identifying referents while other features (...) are reliable. The low computational cost of the incremental algorithm for generating referring expressions makes it an interesting starting point for a cognitive model. However, its explanatory power is limited, because it generates uniquely distinguishing referring expressions and because it considers features for inclusion in the referring expression in a fixed order. The first model extends the original incremental algorithm by an ability to adapt to feedback of whether a referring expression was used successfully, but it seems to overpredict the frequency with which distinguishing expressions are made and underpredict the frequency of overspecified referring expressions. The second model produces features for referring expressions purely based on its current estimate of a feature’s utility. Both models predict the observed human behavior of decreasing use of color terms and increasing use of useful feature terms. (shrink)

People who have not experienced diseases and health conditions tend to judge them to be worse than they are reported to be by people who have experienced them. This phenomenon, known as the disability paradox, presents a challenge for health policy, and in particular, healthcare resource distribution. This divergence between patient and public preferences is most plausibly explained as a result of hedonic adaptation, a widespread phenomenon in which people tend to adapt fairly quickly to the state they are in, (...) good or bad, and adjust their baseline utility accordingly.If patient utilities can be shown to be inappropriate for use in public policy decision making, the disability paradox fades away. This paper offers a critique of one such attempt: the idea that adaptation leads to adaptive preferences. I argue that none of the main accounts of adaptive preferences in fact characterise adapted patient preferences as irrational. Adapted preferences should not, therefore, be treated as synonymous with adaptive preferences. I suggest that much patient adaptation should be understood as a form of the ubiquitous human ability to respond to environmental change. Consequently, we ought not to discount patient preferences.

Climate stresses and monetary resources seem to lead to different collective adaptations. However, the reference to adaptation and to ambiguous collective dimensions appears premature; populations may entertain nothing more than shared adaptiveness. At this point, the intricacy of the underlying evolutionary processes (cultural selection, fitness-utility decoupling) very much obscures any diagnosis based on correlations.

Aspiring Minds Computer Adaptive Test (AMCAT) is a computer adaptive test used widely in India to assess the employability skill level of engineering students. Prefinal and final year students belonging to different streams take up this online test. The present study investigates the perception of students regarding the conduct of AMCAT. Furthermore, the study explores the benefits that they obtain through the test. The comparison is made among the students belonging to the two different streams, engineering and computer (...) science. The conclusion drawn facilitates the readers to understand the utility of AMCAT. (shrink)

This paper axiomatizes a recursive utility model that captures both intertemporal utility smoothing defined across time and ambiguity aversion defined over states. The resulting representation adapts Wakai model of intertemporal utility smoothing as an aggregator function, where the utility of the certainty equivalent of future uncertainty is computed by Gilboa and Schmeidler multiple-priors utility. The model also permits the separation of intertemporal utility smoothing from ambiguity aversion.

Public health ethics is a subfield of bioethics that focuses on population health. This study aims to conform the principles of biomedical ethics to Islamic values in the context of public health. It culturally helps to optimize health care delivery. The approach is based on the method of immanent critique. The principle of the common good in Islam has a rational justification to draw public interests and ward off harms. The rule of “no harm”, with an emphasis on the preferability (...) of preventing harm to increase benefits, is consistent with the principle of utility, intending to produce a maximum balance of benefit over harm in the context of public health. Thus, on the one hand, the government is obliged to prevent harm and improve public benefits and, on the other hand, as a steward of health and with reference to the article “limitation of the ownership dominance”, it has the right to protect public health with the least justifiable harm. Islam attention to human dignity, individual justice and good will in the rule of goodness implies that Islam, beyond distributive justice, knows that human flourishing and the cultivation of moral virtues are a requisite for the realization of social justice. The present study discusses about the adjustment of the principles of PHE to the principles of the Islamic jurisprudence and, at the same time, it explains why the optimal PH in Muslim societies requires research in order to define accurate indicators of benefit and harm based on the teachings of revelation and reason.

This paper proposes a novel adaptive fuzzy super-twisting sliding mode control scheme for microgyroscopes with unknown model uncertainties and external disturbances. Firstly, an adaptive algorithm is used to estimate the unknown parameters and angular velocity of microgyroscopes. Secondly, in order to improve the performance of the system and the superiority of the super-twisting algorithm, this paper utilizes the universal approximation characteristic of the fuzzy system to approach the gain of the super-twisting sliding mode controller and identify the gain (...) of the controller online, realizing the adaptive adjustment of the controller parameters. Simulation results verify the superiority and the effectiveness of the proposed approach, compared with adaptive super-twisting sliding mode control without fuzzy approximation; the proposed method is more effective.

In this article, I firstly discuss why a prioritarian clause can rescue the utilitarian doctrine from the risk of exacerbating inequality in the distribution of resources in those cases in which utility of income does not decline at the margin. Nonetheless, when in the presence of adaptive preferences, classic prioritarianism is more likely than utilitarianism to increase the inequality of resources under all circumstances, independently of the diminishing trend of utility. Hence, I propose to shift the informational (...) focus of prioritarianism from welfare to either social income or capabilities in order to safeguard those who are worse off. Following this, I argue that we may have reasons to limit the aggregative logic of priority-amended utilitarianism through one or more sufficiency thresholds, and that we can partially defuse the negative-thesis objection that is usually levelled against sufficientarianism, provided we interpret the threshold(s) as valid only as long as everyone is led above it.

In lieu of an abstract, here is a brief excerpt of the content:Utility and Morality: Adam Smith's Critique of Hume Marie A. Martin Reading Smith's Theory ofMoral Sentiments one cannot help but note that, in spite ofthe obvious similarities between Smith and Hume and the equally obvious borrowings and adaptions Smith makesofportions of Hume's theory, the two differ substantially on the role of utility in morality. The difference is, in fact, practically diametrical opposition. Hume believed that utility (...) was the "foundation of the chief part of morals." Smith, on the other hand, believed that, while utility may contribute an additional beauty to virtue, it is never the source oftheir virtue and rarely the source of moral approbation. Given their agreement in so many other respects, why the difference regarding utility? To answer this question I shall examine both Smith's specific criticisms ofHume regarding the role ofutility in morals and his more general objections to any theory that makes an appeal to utility a foundation ofmoral approval. I shall show that, while Smith does raise anumber ofgenuine difficulties for Hume's theory, he does not succeed in his most serious criticism, that is, that Hume's theory does not adequately capture the essentially social nature ofmorality. Hume's View ofthe Role ofUtility AccordingtoHume, the sentimentofmoral approbation arisesfrom the perception ofqualities ofcharacter or mind which are either useful or agreeable to ourselves or others. Examples of qualities agreeable to ourselves include cheerfulness, confidence, self-respect, and taste. Examples of qualities agreeable to others include manners, wit, eloquence, andmodesty. But themajorityofourmoral sentiments arise from the perception of the usefulness of qualities, that is, "from reflexions on their tendency to the happiness of mankind, and of particularpersons."2 Utility or usefulness is nothing but a tendency to a certain end. But, Hume claims, "itis acontradictioninterms, thatany thingpleases as means to an end, where the end itself no wise affects us" (E 219). Thus, ifwe approve ofthose qualities thathave a tendency to promote the happiness or well-being of either the possessor or others, it must be eitherbecause we value theirhappinessin itselforbecause we value it as a means to our own interests. Volume XVI Number 2 107 MARIE A. MARTIN Hume rejects the second alternative as contrary to experienced fact. The "selfish systems" which attempt to reduce all moral approbation to self-interest cannot account for our praise and admiration ofthe courage and fortitude ofour enemies even when their consequences thwart our own interests. Neither can such systems account for the fact that "[w]e frequently bestow praise on virtuous actions, performed in very distant ages and remote countries; where the utmost subtilty ofimagination would not discover any appearance ofself-interest" (E 215-16). If it is not self-interest that leads us to approve useful qualities, thenitis clear that"[w]e must adopt amore public affection, and allow, that the interests ofsocietyare not, even on their own account, entirely indifferent to us" (E 219). We approve of qualities that promote the well-being of others because we have a natural concern for their welfare. In general, it is certain, that, wherever we go, whatever we reflect on or converse about, every thing still presents us with the view of human happiness or misery, and excites in our breast a sympathetic movement of pleasure or uneasiness. (E 221) Thus, our approval of useful qualities rests on their tendency to promote the happiness of those who possess or are affected by them, and this, in turn, rests on sympathy, the communication of passions, whereby we "feel" for others—happiness for theirjoys, sorrow for their miseries. So, althoughtheutilityofqualitiesofcharacteris notthe solecause ofour approbation, it is the most extensive and important one. It appears tobe matter offact, that the circumstance oíutility, in all subjects, is a source ofpraise and approbation: That it is constantly appealed to in all moral decisions concerning the merit and demerit ofactions: That it is the sole source ofthat high regard paid to justice, fidelity, honour, allegiance, and chastity: That it is inseparable from all the other social virtues, humanity, generosity, charity, affability, lenity, mercy, and moderation: And, in a word, that it is the foundation ofthe chief part of morals, which has a reference to mankind and our fellow-creatures.

Jim Joyce has presented an argument for Probabilism based on considerations of epistemic utility [Joyce, 1998]. In a recent paper, I adapted this argument to give an argument for Probablism and the Principal Principle based on similar considerations [Pettigrew, 2012]. Joyce’s argument assumes that a credence in a true proposition is better the closer it is to maximal credence, whilst a credence in a false proposition is better the closer it is to minimal credence. By contrast, my argument in (...) that paper assumed (roughly) that a credence in a proposition is better the closer it is to the objective chance of that proposition. In this paper, I present an epistemic utility argument for Probabilism and the Principal Principle that retains Joyce’s assumption rather than the alternative I endorsed in the earlier paper. I argue that this results in a superior argument for these norms. (shrink)

A utility-based approach to the understanding of vague predicates (VPs) is proposed. It is argued that assignment of truth values to propositions containing VPs entails unjustifiable assumptions of consensus; two models of VP semantics are criticized on this basis: (1) the super-truth theory of Kit Fine (1975), which requires an unlikely consensus on base points; (2) the fuzzy logic of Lotfi Zadeh (1975), on fuzzy truth values of sentences. Pragmatism is held to provide a key: successful behavior justifies a (...) person's knowledge of the content of a VP. Instead of attempting to determine a consensus underlying successful communication, the utility of individual communications is held to rest on sufficient approximation of meanings between people. 3 Figures, 17 References.

Specifying exact selection pressures for identifying adaptations is unnecessary. Novel behaviors are not spandrels since they can only develop because of prior functions. An adaptationist approach has a high prior probability, whereas spandrel hypotheses attempt to prove a negative. The concept of maladaptive spandrel is criticized. The utility of dysfunctional states for identification of adaptations gone wrong is emphasized.

As schizotypal personality disorder increasingly prevails in the general population, a rapid and comprehensive measurement instrument is imperative to screen individuals at risk for SPD. To address this issue, we aimed to develop a computerized adaptive testing for SPD using a non-clinical Chinese sample, consisting of a calibration sample and a validation sample. The item pool of SPD was constructed from several widely used SPD scales and statistical analyses based on the item response theory via a calibration sample using (...) a graded response model. Finally, 90 items, which measured at least one symptom of diagnostic criteria of SPD in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders and had local independence, good item fit, high slope, and no differential item functioning, composed the final item pool for the CAT-SPD. In addition, a simulated CAT was conducted in an independent validation sample to assess the performance of the CAT-SPD. Results showed that the CAT-SPD not only had acceptable reliability, validity, and predictive utility but also had shorter but efficient assessment of SPD which can save significant time and reduce the test burden of individuals with less information loss.

This article extends the Humean example of evolutionary stakeholder theory introduced in Kline and McDermott (2019). In that article, it was established that the Cost of Service Regulation (COSR) rules created by regulatory commissions, courts, and legislation was an example of evolutionary stakeholder theory. Ultimately, the Supreme Court decision in the Hope Natural Gas case established that it was not the method, but the result reach that was important. If the result reach balanced the interests of stakeholders then the outcome (...) was just and reasonable. Kline and McDermott (2019) also established that the COSR process was rather robust in terms of stakeholder participation. The purpose of this article is to extend the analysis to examine one of the most turbulent periods in COSR's history: the Post‐OPEC oil crisis of the 1970s–1980s. The effects of this period called into question the efficacy of the COSR process and led, as evolutionary stakeholder theory predicts, to a series of engagements by stakeholders to modify the rules of the process to achieve a better balance in the publics' interest. While adjudicatory in nature, the COSR process enabled cooperative solutions to redress the imbalances created by the OPEC oil shocks, improvements in information gathering, processing and decision‐making were all products of the evolutionary stakeholder process that regulators engaged in with stakeholders.

Functional information means an encoded network of functions in living organisms from molecular signaling pathways to an organism’s behavior. It is represented by two components: code and an interpretation system, which together form a self-sustaining semantic closure. Semantic closure allows some freedom between components because small variations of the code are still interpretable. The interpretation system consists of inference rules that control the correspondence between the code and the function (phenotype) and determines the shape of the fitness landscape. The (...) class='Hi'>utility factor operates at multiple time scales: short-term selection drives evolution towards higher survival and reproduction rate within a given fitness landscape, and long-term selection favors those fitness landscapes that support adaptability and lead to evolutionary expansion of certain lineages. Inference rules make short-term selection possible by shaping the fitness landscape and defining possible directions of evolution, but they are under control of the long-term selection of lineages. Communication normally occurs within a set of agents with compatible interpretation systems, which I call communication system. Functional information cannot be directly transferred between communication systems with incompatible inference rules. Each biological species is a genetic communication system that carries unique functional information together with inference rules that determine evolutionary directions and constraints. This view of the relation between utility and inference can resolve the conflict between realism/positivism and pragmatism. Realism overemphasizes the role of inference in evolution of human knowledge because it assumes that logic is embedded in reality. Pragmatism substitutes usefulness for truth and therefore ignores the advantage of inference. The proposed concept of evolutionary pragmatism rejects the idea that logic is embedded in reality; instead, inference rules are constructed within each communication system to represent reality, and they evolve towards higher adaptability on a long time scale.

We propose a framework for including information‐processing bounds in rational analyses. It is an application of bounded optimality (Russell & Subramanian, 1995) to the challenges of developing theories of mechanism and behavior. The framework is based on the idea that behaviors are generated by cognitive mechanisms that are adapted to the structure of not only the environment but also the mind and brain itself. We call the framework computational rationality to emphasize the incorporation of computational mechanism into the definition of (...) rational action. Theories are specified as optimal program problems, defined by an adaptation environment, a bounded machine, and a utility function. Such theories yield different classes of explanation, depending on the extent to which they emphasize adaptation to bounds, and adaptation to some ecology that differs from the immediate local environment. We illustrate this variation with examples from three domains: visual attention in a linguistic task, manual response ordering, and reasoning. We explore the relation of this framework to existing “levels” approaches to explanation, and to other optimality‐based modeling approaches. (shrink)

This paper investigates how environmental structure, given the innate properties of a population, affects the degree to which this population can adapt to the environment. The model we explore involves simple agents in a 2-d world which can sense a local food distribution and, as specified by their genomes, move to a new location and ingest the food there. Adaptation in this model consists of improving the genomic sensorimotor mapping so as to maximally exploit the environmental resources. We vary environmental (...) structure to see its specific effect on adaptive success. In our investigation, two properties of environmental structure, conditioned by the sensorimotor capacities of the agents, have emerged as significant factors in determining adaptive success: (1) the information content of the environment which quantifies the diversity of conditions sensed, and (2) the expected utility for optimal action. These correspond to the syntactic and pragmatic aspects of environmental information, respectively. We find that the ratio of expected utility to information content predicts adaptive success measured by population gain and information content alone predicts the fraction of ideal utility achieved. These quantitative methods and specific conclusions should aid in understanding the effects of environmental structure on evolutionary adaptation in a wide range of evolving systems, both artificial and natural.

Reverse engineering is a matter of inferring adaptive function from structure. The utility of reverse engineering for evolutionary biology has been a matter of controversy. I offer a simple taxonomy of the uses of engineering design in assessing adaptation, with a variety of illustrations. The plausibility of applications of engineering design reflects the specific way the models are elaborated and derived.

Mechanisms for QoS provisioning in communication networks range from flow-based resource reservation schemes, providing QoS guarantees, through QoS differentiation based on reservation aggregation techniques to adaptation of applications, compensating for incomplete reservations. Scalable, aggregation-based reservations can also be combined with adaptations for a more flexible and robust overall QoS provisioning. Adaptation is particularly important in wireless networks, where reservations schemes are more difficult to realize. It is widely accepted that usability of Cellular or Mobile IP can be largely improved if (...) adaptation is incorporated. Adaptation, in turn, depends on coding techniques involved and on user requirements. Those impose certain preferences and ordering relations on QoS hierarchies or degradation paths to be followed along when adaptation is performed. With the advent of MPEG4 coding techniques, more sophisticated adaptation schemes are more likely to be supported in the future. (shrink)

“Trait” is a ubiquitous term in biology, but its precise meaning and theoretical foundations remain opaque. After distinguishing between “trait” and “character,” I argue for the value of adopting Theodosius Dobzhansky’s 1956 definition and framework for understanding “trait,” which holds that traits are just “semantic devices” that artificially impose order on continuous biological phenomena. I elaborate on this definition to distinguish between trait validity (compliance with Dobzhansky’s trait definition) and trait utility (usefulness of a trait). As a consequence of (...) this elaboration of the meaning of “trait,” it becomes clear that considerations of adaptation, function, homogeneity and natural kinds have clouded discussions of the meaning of “trait” per se. Combining this account with work by David Hull and examples from contemporary biology, I demonstrate that even broad or heterogeneous traits (including multiple sub-traits) can qualify as valid and useful. As a test case for this understanding of trait, I show how it can help resolve critiques of schizophrenia’s status as a single trait, highlighting the recent advances made within schizophrenia research.

Traditional justifications for state-to-state development assistance include charity, basic rights and self-interest. Except in unusual cases such as war-reparations agreements, development assistance has typically been justified for reasons such as the above, without reference to any history of injury that holds between the states.

Finally, to demonstrate the utility of this analysis, we offer a brief application (...) of our reasoning to the emerging conflict in the United Nations over the future post-2015 development agenda.

Nonbelievers represent an understudied population in Greece. This investigation reports on the translation, cultural adaptation, and initial validation of the Nonreligious-Nonspiritual Scale, a measure designed to assess nonbelief. Data from 1754 participants were collected to examine the psychometric properties of the Greek version of the instrument and to assess the nationwide interpretability of the measure. Factor analyses suggested that the 16-item scale retained its bifactor model. Convergent validity was supported through associations with additional measures, namely, the Meaning in Life Questionnaire (...) and the Connor–Davidson Resilience Scale, which were used as reference criteria. Potential utility of the measure and future directions for ongoing development are discussed. (shrink)

The paper presents evidence in bacteria for the utility of Godfrey-Smith’s environmental complexity thesis, using certain kinds of signal transduction systems as proxies for cognitive/behavioral complexity. Microbiologists already accept that the number of signal transduction proteins in a bacterial genome indicates the level of ecological complexity to which the organism is subject: the more signalling proteins, the greater the complexity. Sheer numbers are not always a reliable indicator of behavioral complexity, however. The paper proposes a new, ECT-based procedure for (...) identifying, from genomic sequence and signalling repertoire, novel bacterial candidates likely to exhibit behavioral complexity in response to a complex ecological niche.

This cross-sectional study investigated the efficacy of an extended theory of planned behavior in predicting academic dishonesty among students of higher education. The participants comprised 328 undergraduates drawn from Nigerian and Malaysian public universities. Existing measures were adapted and validated using Cronbach’s alpha statistics and confirmatory factor analysis approach. The fit statistics of the extended model (χ2/df = 2.08, CFI =.926, and RMSEA =.057) were adequate. Findings revealed that academic dishonesty, especially cheating, was common in the sampled population. The key (...) psychological factors contributing to this problem were positive attitude towards the conducts, lack of strict sanctions against the conducts, and a perceived self-confidence of some students to cheat successfully. Another strong factor was the belief that intellectual material is “public property.” The modified model was not gender-bias, suggesting that the underpinning factors were similar irrespective of the gender-type of the students. Hence, a unified, non-gender discriminating approach will be effective in planned actions towards reversing the trend. (shrink)

The present text signals the crisis of philosophy due to a series of factors such as: the difficulties that the philosophical discourse has in finding (...) a place in the public debate, the negative perception of philosophy in the public mentality, the stereotypes concerning philosophy that the political representatives cultivate, and the lack of a labor market that would adequately value the competences and the expertise of the graduates in Humanities.

We argue that religious ritual's ability to facilitate communication and the pervasiveness of its basic characteristics across societies, as well as its precedence in other social species, suggests that religious behavior is more than a mere by-product. Religious constructs constitute associationally conditioned mnemonics that trigger neuroendocrine responses which motivate religious behaviors. The adaptive value of these constructs resides in their utility as memorable and emotionally evocative primes.

Animals routinely adapt to changes in the environment in order to survive. Though reinforcement learning may play a role in such adaptation, it is not clear that it is the only mechanism involved, as it is not well suited to producing rapid, relatively immediate changes in strategies in response to environmental changes. This research proposes that counterfactual reasoning might be an additional mechanism that facilitates change detection. An experiment is conducted in which a task state changes over time and the (...) participants had to detect the changes in order to perform well and gain monetary rewards. A cognitive model is constructed that incorporates reinforcement learning with counterfactual reasoning to help quickly adjust the utility of task strategies in response to changes. The results show that the model can accurately explain human data and that counterfactual reasoning is key to reproducing the various effects observed in this change detection paradigm. (shrink)

Mahr & Csibra (M&C) fail to make the important distinction between why a trait originally evolved, why it was maintained over time, and what its current utility is.

This paper is about the shaping of student workload preferences by educational institution design, and how this creates distrust by staff in those preferences when staff are asked to use those preferences in re-designing the courses they teach. It is a case study of the construction of student workload preferences by the context of a particular higher education institution. In more detail: Failures to standardize the work required to receive equal credit points from different courses make credit points unfit for (...) their official purposes. Moreover, increasingly, institutions are found where students are required to take a high number of courses simultaneously. This study aimed to identify plausible hypotheses about how high course-loads and standardization failure interact by examining credit point standardization failure at an Estonian university where students are required to take twice as many courses as their peers at better performing universities. The hypotheses supported by the study are: the high course-load both made standardization failure useful to students seeking to manage the high course-load and contributed toward standardization failure because it rendered students’ assessments of workload untrustworthy to lecturers who regulate that workload. Existing advice on standardization of workloads within the European Credit Transfer and Accumulation System is criticized for its insensitivity to the constructive effects of course-load on student workload preferences.

Scholars employing an evolutionary approach to the study of religion and religious beliefs search for ultimate explanations of the origin, propagation, and persistence of religious beliefs. This quest often pairs in debate two opposing perspectives: the adaptationist and “by-product” explanations of religion and religious beliefs.

Despite this pervasive negativity, it seems unwarranted to deny the great usefulness of religious beliefs—particularly concerning (...) their past utility. Instead, adaptationist explanations of religion and religious beliefs must be re-established as interesting and useful approaches to the study of religious beliefs. (shrink)

The COVID-19 outbreak has simultaneously increased the need for mental health services and decreased their availability. Brief online self-help interventions that can be completed in a single session could be especially helpful in improving access to care during the crisis. However, little is known about the uptake, acceptability, and perceived utility of these interventions outside of clinical trials in which participants are compensated. Here, we describe the development, deployment, acceptability ratings, and pre–post effects of a single-session intervention, the Common (...) Elements Toolbox, adapted for the COVID-19 crisis to support graduate and professional students. Participants, who were not compensated, were randomly assigned to two of three modules: behavioral activation, cognitive restructuring, and gratitude. Over 1 week, 263 individuals began and 189 individuals completed the intervention. Participants reported that the intervention modules were acceptable, helpful, engaging, applicable to their lives, and could help them manage COVID-related challenges. Participants reported pre- to post-program improvements in secondary control and in the perceived negative impact of the COVID-19 crisis on their quality of life. On average, differences in their perceived ability to handle lifestyle changes resulting from the pandemic were positive, but small and at the level of a non-significant trend. Our results highlight the acceptability and utility of an online intervention for supporting individuals through the COVID-19 crisis. (shrink)

Probability updating via Bayes' rule often entails extensive informational and computational requirements. In consequence, relatively few practical applications of Bayesian adaptive control techniques have been attempted. This paper discusses an alternative approach to adaptive control, Bayesian in spirit, which shifts attention from the updating of probability distributions via transitional probability assessments to the direct updating of the criterion function, itself, via transitional utility assessments. Results are illustrated in terms of an adaptive reinvestment two-armed bandit problem.

Background: The quality of medical education plays a significant role in shaping the career outcomes of international students. As they navigate the challenges of their studies and career paths in a foreign country, understanding the elements that influence their career adaptability is essential. Objective: This study aims to examine the impact of medical education quality on career adaptability among international students in China and to emphasize the mediating role of proactive career planning behavior. It also investigates challenges related to cultural (...) adjustment. Methodology: A quantitative technique is employed in a cross-sectional survey of international medical students in China. Information was collected from 575 valid responses through structured questionnaires. The research utilizes regression analysis and Structural Equation Modeling (SEM) to assess the relationships between medical education quality, career adaptability, proactive career planning behavior, and cultural adjustment challenges. Result: The evaluation revealed that medical education quality positively influences career adaptability (p < 0.001, β = 0.45). Proactive career planning behavior was found to positively influence career adaptability (p < 0.001, β = 0.38). Medical education quality positively influences proactive career planning behavior (p < 0.001, β = 0.50), and proactive career planning behavior mediated the connection between medical education quality and career adaptability (p = 0.013, β = 0.20). Cultural adjustment challenges moderated the relationship between medical education quality and career adaptability, with a significant interaction effect (p = 0.032, β = -0.15). Conclusion: The research emphasizes the significance of high-quality medical education in promoting career adaptability among international students, highlighting proactive career planning and examining cultural adjustment challenges for optimal career outcomes. These insights can inform educational practices and support services for international medical students, aiming to enhance their career readiness and adaptability in a global context. (shrink)

The Cry family of Bacillus thuringiensis insecticidal and nematicidal proteins constitutes a valuable source of environmentally benign compounds for the control of insect pests and disease agents. An understanding of Cry toxin resistance at a molecular level will be critical to the long‐term utility of this technology; it may also shed light on basic mechanisms used by other bacterial toxins that target specific organisms or cell types. Selection and cross‐resistance studies have confirmed that genetic adaptation can elicit varying patterns (...) of Cry toxin resistance, which has been associated with deficient protoxin activation by host proteases, and defective Cry toxin‐binding cell surface molecules, such as cadherins, aminopeptidases and glycolipids. Recent work also suggests Cry toxin resistance may be induced in invertebrates as an active immune response. The use of model invertebrates, such as Caenorhabditis elegans and Drosophila melanogaster, as well as advances in insect genomics, are likely to accelerate efforts to clone Cry toxin resistance genes and come to a detailed and broad understanding of Cry toxin resistance.

China is located in the intersection area of two seismic zones. Due to this special geographical location, earthquake disasters occur frequently in China. Earthquake emergency rescue work is one of the key construction works of disaster prevention and mitigation in China. This paper mainly studies the earthquake disaster rescue model based on the complex adaptive system theory and establishes the earthquake disaster rescue model by analyzing the complex adaptive system theory and combining the earthquake rescue process. In this (...) paper, through the task allocation mechanism task, the disaster rescue task is divided into simple task and complex task, and the executive task subject is divided into single task subject and multitask subject. On the basis of considering the shortest emergency rescue time goal and the goal of maximizing the deployment utility of rescue team, the reasonable deployment of a rescue team is realized through a complex adaptive system, that is, the deployment utility of the rescue team is maximized. In this paper, the simulation experiment and comparison of the earthquake disaster rescue model based on the complex adaptive system theory are carried out. The experimental results show that the model used in this paper is better than the other two models in terms of algorithm convergence, rescue number, and overall score; in different scenarios, the relative survival probability of the model in this paper is 58.92%, 67.85%, and 77.46%, and the proportion of the wounded rescued is 66.31%, 76.45%, and 83.06%, which were higher than those of the other two models. The earthquake disaster rescue model based on the complex adaptive system theory proposed in this paper provides an effective theoretical basis and method system for postdisaster emergency rescue decision making and enhances and improves the emergency response ability to deal with large-scale geological disaster events.

Quality-Adjusted Life Years (QALYs) and Disability-Adjusted Life Years (DALYs) are two of the most commonly used health measures to determine resource prioritization and the population burden of disease, respectively. There are different types of problems with the use of QALYs and DALYs for measuring health benefits. Some of these problems have to do with measurement, for example, the weights they ascribe to health states might fail to reflect with exact accuracy the actual well-being or health levels of individuals. But even (...) if these weights represent accurately the well-being levels of individuals, there is room for questioning whether these measures capture everything that we care about in these cases, or whether there are important issues that they leave out, including considerations of fairness or equality. In this regard, the measures have been criticized for treating the aggregation of small benefits as greater than the aggregation of fewer but bigger benefits,1for disregarding fair chances in favor of utility maximization,2and for raising problems when applied in the context of variable population size.3Perhaps one of the most pervasive ethical issues that has been associated with the use of these measures is the fact that they seem to discriminate against disabled people.4Since the measures assume that disabled people have lower well-being and a shorter life span, treating a disabled person’s medical condition contributes less to the maximization of years of life with good health than treating a non-disabled patient’s medical condition.

This paper argues that the graphic adaptation of Dennis Lehane’s Shutter Island utilizes the medium to evoke an affective participation and investment from the reader. It explores the ways the graphic novel overcomes problematic representations of mental illness in the popular film version. Drawing on graphic fiction theory, I contend that readers’ engagement in and construction of the story between panels, in the “gutters,” allows them to participate in the protagonist’s persecutory delusion. Additionally, I draw on Foucault’s conceptualizations of the (...) medical gaze and historical figurations of madness connected to water in order to demonstrate the mechanism by which the reader is placed in a dual subject position, becoming both observer and observed. In this capacity, I suggest that graphic fiction provides a unique experience to engender empathy for psychiatric illness. (shrink)

In recent years, a number of commentators have expressed dissatisfaction with Spinoza’s account of practical reason. In this paper, I defend his account against the most prominent objections, showing that the dictates of reason play an important role in guiding thought and action. However, against the standard interpretation, I propose that we view these rules not as exceptionless, instrumental prescriptions—hypothetical imperatives with necessary antecedents, as Curley memorable put it—but rather as adaptable guideposts that aid us in the complex, dynamic process (...) of acquiring a habit of virtue. The dictates of reason are best understood as defeasible policies that help to orient one in the ars vivendi. (shrink)

The low rates of regular exercise and overall physical activity (PA) in the general population represent a significant public health challenge. Previous research suggests that, for many people, exercise leads to a negative affective response and, in turn, reduced likelihood of future exercise. The purpose of this paper is to examine this exercise–affect–adherence relationship from an evolutionary perspective. Specifically, we argue that low rates of physical exercise in the general population are a function of the evolved human tendency to avoid (...) unnecessary physical exertion. This innate tendency evolved because it allowed our evolutionary ancestors to conserve energy for physical activities that had immediate adaptive utility such as pursuing prey, escaping predators, and engaging in social and reproductive behaviors. The commonly observed negative affective response to exercise is an evolved proximate psychological mechanism through which humans avoid unnecessary energy expenditure. The fact that the human tendencies toward negative affective response to and avoidance of unnecessary physical activities are innate does not mean that they are unchangeable. Indeed, it is only because of human-engineered changes in our environmental conditions (i.e., it is no longer necessary for us to work for our food) that our predisposition to avoid unnecessary physical exertion has become a liability. Thus, it is well within our capabilities to reengineer our environments to once again make PA necessary or, at least, to serve an immediate functional purpose. We propose a two-pronged approach to PA promotion based on this evolutionary functional perspective: first, to promote exercise and other physical activities that are perceived to have an immediate purpose, and second, to instill greater perceived purpose for a wider range of physical activities. We posit that these strategies are more likely to result in more positive (or less negative) affective responses to exercise, better adherence to exercise programs, and higher rates of overall PA.

The question of whether the visual world is a grand illusion is addressed and answered negatively. The question only arises because of the recent work on Inattentional Blindness , Change Blindness and the Attentional Blink which establishes that attention is necessary for perception. It is argued that IB occurs only when attention is narrowly focussed and not when attention is more broadly distributed, which is the more typical attentional state. Under conditions of distributed attention we are likely to have a (...) fuller, if less detailed, impression of the visual scene, which may be why we are so surprised by demonstrations of IB, AB and CB. It is also argued that the question about the possible illusory quality of our perceptual world cannot be avoided by denying that inattention causes blindness and asserting instead that it causes amnesia. This argument is grounded on the similarity between these phenomena and visual neglect and by evidence that priming by the unseen stimuli occurs in each case indicating that the stimuli to which we are functionally blind are processed and represented in implicit memory. The adaptive utility of this information is discussed. (shrink)

Roy Sorensen advances an evolutionary explanation of our capacity for thought experiments which doubles as a naturalized epistemological justification. I argue Sorensens explanation fails to satisfy key elements of environmental-selectionist explanations and so fails to carry epistemic force. I then argue that even if Sorensen succeeds in showing the adaptive utility of our capacity, he still fails to establish its reliability and hence epistemic utility. I conclude Sorensens account comes to little more than a just-so story.

Most economists and some philosophers distinguish individual utilities from interpersonal social values. Even if challenges to that conceptual distinction can be met, further philosophically interesting questions arise. I pursue three in this paper, using, as context for the discussion, health economics and its attempt to discern empirically a social welfare function to help guide rationing decisions. (1) To discern these utilities and values in a manner that is morally appropriate if they are to influence rationing decisions, who should be queried? (...) To discern individual health state utilities, persons in precisely those states should be asked (generically, patients), but for social values, representatives of the general public should be. (2) To discern social values, what should representatives of the public be asked? They should be asked person trade-off (PTO) questions that encompass their own self-interest, not PTO questions that focus only on others. (3) What must public representatives understand before they respond to such questions? Despite the philosophically complex problem of patient adaptation, they should understand (among other things) the health state utilities elicited from actual patients with the conditions at issue.

It is known that, on average, people adapt their choice of memory strategy to the subjective utility of interaction. What is not known is whether an individual's choices are boundedly optimal. Two experiments are reported that test the hypothesis that an individual's decisions about the distribution of remembering between internal and external resources are boundedly optimal where optimality is defined relative to experience, cognitive constraints, and reward. The theory makes predictions that are tested against data, not fitted to it. (...) The experiments use a no-choice/choice utility learning paradigm where the no-choice phase is used to elicit a profile of each participant's performance across the strategy space and the choice phase is used to test predicted choices within this space. They show that the majority of individuals select strategies that are boundedly optimal. Further, individual differences in what people choose to do are successfully predicted by the analysis. Two issues are discussed: the performance of the minority of participants who did not find boundedly optimal adaptations, and the possibility that individuals anticipate what, with practice, will become a bounded optimal strategy, rather than what is boundedly optimal during training.

The impact of incidental emotions on decision making is well established. Incidental emotions can be differentiated on several appraisal dimensions, including certainty–uncertainty. The present research investigates the effect of certainty–uncertainty of incidental emotions on hedonic forecasting. The results of four experimental studies indicate that uncertainty-associated incidental emotions, such as fear and hope, compared with certainty emotions, such as anger and happiness, amplify predicted utility. This amplification effect is confirmed for opposite utility types; uncertainty-associated emotions, when compared with their (...) certainty counterparts, lead to an overprediction of positive utilities and to an underprediction of negative utilities. This effect is mediated by the prediction task uncertainty, providing evidence for a carryover process of the incidental emotion. The effect of task uncertainty on predicted utility is, in turn, partly mediated by attention to the task, suggesting that an affective adaptation process lies behind the amplification of forecasts. Taken together, these findings extend the impact of certainty–uncertainty to the context of hedonic forecasting and further corroborate the impact of incidental emotions in judgment and decision making.
