Evolutionary transitions in individuality (ETIs) involve the formation of Darwinian collectives from Darwinian particles. The transition from cells to multicellular life is a prime example. During an ETI, collectives become units of selection in their own right. However, the underlying processes are poorly understood. One observation used to identify the completion of an ETI is an increase in collective-level performance accompanied by a decrease in particle-level performance, for example measured by growth rate. This seemingly counterintuitive dynamic has been (...) referred to as fitness decoupling and has been used to interpret both models and experimental data. Extending and unifying results from the literature, we show that fitness of particles and collectives can never decouple because calculations of fitness performed over appropriate and equivalent time intervals are necessarily the same provided the population reaches a stable collective size distribution. By way of solution, we draw attention to the value of mechanistic approaches that emphasise traits, and tradeoffs among traits, as opposed to fitness. This trait-based approach is sufficient to capture dynamics that underpin evolutionary transitions. In addition, drawing upon both experimental and theoretical studies, we show that while early stages of transitions might often involve tradeoffs among particle traits, later—and critical—stages are likely to involve the rupture of such tradeoffs. Thus, when observed in the context of ETIs, tradeoff-breaking events stand as a useful marker of these transitions. (shrink)

The rapid diffusion of artificial intelligence (AI) technologies in the defence domain raises challenges for the ethical governance of these systems. A recent shift from the what to the how of AI ethics sees a nascent body of literature published by defence organisations focussed on guidance to implement AI ethics principles. These efforts have neglected a crucial intermediate step between principles and guidance concerning the elicitation of ethical requirements for specifying the guidance. In this article, we outline the key normative (...) choices and corresponding tradeoffs that are involved in specifying guidance for the implementation of AI ethics principles in the defence domain. These correspond to: the AI lifecycle model used; the scope of stakeholder involvement; the accountability goals chosen; the choice of auditing requirements; and the choice of mechanisms for transparency and traceability. We provide initial recommendations for navigating these tradeoffs and highlight the importance of a pro-ethical institutional culture. (shrink)

How do people interleave attention when multitasking? One dominant account is that the completion of a subtask serves as a cue to switch tasks. But what happens if switching solely at subtask boundaries led to poor performance? We report a study in which participants manually dialed a UK-style telephone number while driving a simulated vehicle. If the driver were to exclusively return his or her attention to driving after completing a subtask (i.e., using the single break in the xxxxx-xxxxxx (...) representational structure of the number), then we would expect to see a relatively poor driving performance. In contrast, our results show that drivers choose to return attention to steering control before the natural subtask boundary. A computational modeling analysis shows that drivers had to adopt this strategy to meet the required performance objective of maintaining an acceptable lateral position in the road while dialing. Taken together these results support the idea that people can strategically control the allocation of attention in multitask settings to meet specific performance criteria. (shrink)

ABSTRACT Setting specific, challenging goals motivates employees to exert greater effort in their jobs. However, goal-setting may have unintended consequences of also motivating unethical behavior. The present study explores these consequences in the context of other features of goal-setting in organizations, how goals are framed and rewarded, to determine the tradeoff between performance and ethical behavior. Undergraduate students were incentivized to complete math problems using different outcome frames and incentive structures and were also provided an opportunity to cheat. Findings (...) demonstrate that when goals rewarded with piece-rate incentives are framed as a loss, performance increased, though cheating behavior increased as well. (shrink)

Our analysis of recent survey data of US small- and medium-sized enterprises explores the question of how these entrepreneurial ventures can do well by doing good—i.e., how they can build a competitive advantage with their social and environmental practices. We focus on several firm characteristics and choices involving motivations and capabilities. We use hierarchical OLS to analyze the survey data to find that an orientation to, commitments to, and dynamic flexibility in, the firm’s CSR and green policies are significant factors (...) in a firm’s CSR- and green-based competitive advantages. So, while some tradeoffs are likely between activities aimed at financial performance and those also aimed at improving social/environmental performance, opportunities do exist for small- and medium-sized enterprises to do both well and good. We consider several implications for theory and practice that continue in this instrumentalist perspective. (shrink)

This paper brings the intellectual tools of cognitive science to bear on resolving the “paradox of the active user” [Interfacing Thought: Cognitive Aspects of Human–Computer Interaction, Cambridge, MIT Press, MA, USA]—the persistent use of inefficient procedures in interactive tasks by experienced or even expert users when demonstrably more efficient procedures exist. The goal of this paper is to understand the roots of this paradox by finding regularities in these inefficient procedures. We examine three very different data sets. For each data (...) set, we first satisfy ourselves that the preferred procedures used by some subjects are indeed less efficient than the recommended procedures. We then amass evidence, for each set, and conclude that when a preferred procedure is used instead of a more efficient, recommended procedure, the preferred procedure tends to have two major characteristics: (1) the preferred procedure is a well‐practiced, generic procedure that is applicable either within the same task environment in different contexts or across different task environments, and (2) the preferred procedure is composed of interactive components that bring fast, incremental feedback on the external problem states. The support amassed for these characteristics leads to a new understanding of the paradox. In interactive tasks, people are biased towards the use of general procedures that start with interactive actions. These actions require much less cognitive effort as each action results in an immediate change to the external display that, in turn, cues the next action. Unfortunately for the users, the bias to use interactive unit tasks leads to a path that requires more effort in the long run. Our data suggest that interactive behavior is composed of a series of distributed choices; that is, people seldom make a once‐and‐for‐all decision on procedures. This series of biased selection of interactive unit tasks often leads to a stable suboptimal level of performance. (shrink)

Errors and their consequences are typically studied by investigating changes in decision speed and accuracy in trials that follow an error, commonly referred to as “post-error adjustments”. Many studies have reported that subjects slow down following an error, a phenomenon called “post-error slowing” (PES). However, the functional significance of PES is still a matter of debate as it is not always adaptive. That is, it is not always associated with a gain in performance and can even occur with a (...) decline in accuracy. Here, we hypothesized that the nature of PES is influenced by one’s speed-accuracy tradeoff policy, which determines the overall level of choice accuracy in the task at hand. To test this hypothesis, we had subjects performing a task in two distinct contexts (separate days), which either promoted speed (hasty context) or cautiousness (cautious context), allowing us to consider post-error adjustments according to whether subjects performed choices with a low or high accuracy level, respectively. Accordingly, our data indicate that post-error adjustments varied according to the context in which subjects performed the task, with PES being solely significant in the hasty context (low accuracy). In addition, we only observed a gain in performance after errors in a specific trial type, suggesting that post-error adjustments depend on a complex combination of processes that affect the speed of ensuing actions as well as the degree to which such PES comes with a gain in performance.

This paper examines flexibility in ad hoc networks and suggests that, even with cross-layer design as a mechanism to improve adaptation, a fundamental limitation exists in the ability of a single optimization function, defined a priori, to adapt the network to meet all quality-of-service requirements. Thus, code implementing multiple algorithms will have to be positioned within the network. Active networking and programmable networking enable unprecedented autonomy and flexibility for ad hoc communication networks. However, in order to best leverage the results (...) of active and programmable networking, metrics that indicate the nature and location of required flexibility need to be developed. The primary contribution of this paper is to propose a metric that couples network topological rate of change with the ability of a generic service to move itself to an optimal location in concert with the changing network. This metric points to a fundamental tradeoff among adaptation (changing service location), performance (sophistication or estimated minimum code size of the service), and the network’s ability to tune itself to a changing ad hoc network topology.

Abstract: In this article, I offer a proposal to clarify what I believe is the proper relation between value maximization and stakeholder theory, which I call enlightened value maximization. Enlightened value maximization utilizes much of the structure of stakeholder theory but accepts maximization of the long-run value of the firm as the criterion for making the requisite tradeoffs among its stakeholders, and specifies long-term value maximization or value seeking as the firm’s objective. This proposal therefore solves the problems that (...) arise from the multiple objectives that accompany traditional stakeholder theory. I also discuss the Balanced Scorecard, which is the managerial equivalent of stakeholder theory, explaining how this theory is flawed because it presents managers with a scorecard that gives no score—that is, no single-valued measure of how they have performed. Thus managers evaluated with such a system (which can easily have two dozen measures and provides no information on the tradeoffs between them) have no way to make principled or purposeful decisions. The solution is to define a true (single dimensional) score for measuring performance for the organization or division (and it must be consistent with the organization’s strategy), and as long as their score is defined properly, (and for lower levels in the organization it will generally not be value) this will enhance their contribution to the firm.

In the last few years, biologists and computer scientists have claimed that the introduction of data science techniques in molecular biology has changed the characteristics and the aims of typical outputs (i.e. models) of such a discipline. In this paper we will critically examine this claim. First, we identify the received view on models and their aims in molecular biology. Models in molecular biology are mechanistic and explanatory. Next, we identify the scope and aims of data science (machine learning in (...) particular). These lie mainly in the creation of predictive models which performances increase as data set increases. Next, we will identify a tradeoff between predictive and explanatory performances by comparing the features of mechanistic and predictive models. Finally, we show how this a priori analysis of machine learning and mechanistic research applies to actual biological practice. This will be done by analyzing the publications of a consortium—The Cancer Genome Atlas—which stands at the forefront in integrating data science and molecular biology. The result will be that biologists have to deal with the tradeoff between explaining and predicting that we have identified, and hence the explanatory force of the ‘new’ biology is substantially diminished if compared to the ‘old’ biology. However, this aspect also emphasizes the existence of other research goals which make predictive force independent from explanation. (shrink)

ABSTRACT In the context of the COVID-19 pandemic, leaders are facing an ethical dilemma and a tense tradeoff between employees’ health and economic performance. From the perspective of employees’ perceptions of the work situation, this study examines the way ethical leadership enhances employee creativity during the COVID-19 pandemic by using leader-member exchange and organizational ethical climate as mediators. The sample included 308 supervisor-employee pairs from 20 high-tech companies in eight provincial regions of China. Structural equation modeling was used to (...) test the proposed hypotheses. Results indicate that ethical leadership can significantly enhance employee creativity through the fully mediating roles of employees’ perceptions of leader-member exchange and organizational ethical climate. Moreover, leader-member exchange affects employee creativity directly as well as indirectly through the mediating role of organizational ethical climate. This study offers insights into the process linking ethical leadership to employee creativity and provides practical suggestions on ways of enhancing employee creativity in situations like the COVID-19 pandemic crisis.

We present a game mechanic called pseudo-visibility for games inhabited by non-player characters (NPCs) driven by reinforcement learning (RL). NPCs are incentivized to pretend they cannot see pseudo-visible players: the training environment simulates an NPC to determine how the NPC would act if the pseudo-visible player were invisible, and penalizes the NPC for acting differently. NPCs are thereby trained to selectively ignore pseudo-visible players, except when they judge that the reaction penalty is an acceptable tradeoff (e.g., a guard might accept (...) the penalty in order to protect a treasure because losing the treasure would hurt even more). We describe an RL agent transformation which allows RL agents that would not otherwise do so to perform some limited self-reflection to learn the training environments in question. (shrink)

We investigated the properties of the sustained attention to response task . In the SART, participants respond to frequent neutral signals and are required to withhold response to rare critical signals. We examined whether SART performance shows characteristics of speed–accuracy tradeoffs and in addition, we examined whether SART performance is influenced by prior exposure to emotional picture stimuli. Thirty-six participants in this study performed SARTs after being exposed to neutral and negative picture stimuli. Performance in the (...) SART changed rapidly over time and there was a high correlation between participants errors of commission rate and their reaction time to the neutral targets . Regardless of exposure self-reported thoughts significantly correlated with both errors of commission and reaction times. Overall, the results support the view that the SART is a better measure of impulsive responding than sustained attention. (shrink)

Spoken word recognition involves a perceptual tradeoff between the reliance on the incoming acoustic signal and knowledge about likely sound categories and their co-occurrences as words. This study examined how adult second language (L2) learners navigate between acoustic-based and knowledge-based spoken word recognition when listening to highly variable, multi-talker truncated speech, and whether this perceptual tradeoff changes as L2 listeners gradually become more proficient in their L2 after multiple months of structured classroom learning. First language (L1) Mandarin Chinese listeners and (...) L1 English-L2 Mandarin adult listeners took part in a gating experiment. The L2 listeners were tested twice—once at the start of their intermediate/advanced L2 language class and again two months later. L1 listeners were only tested once. Participants were asked to identify syllable-tone words that varied in syllable token frequency (high/low according to a spoken word corpus) and syllable-conditioned tonal probability (most probable/least probable in speech given the syllable). The stimuli were recorded by 16 different talkers and presented at eight gates ranging from onset-only (gate 1) through onset+40 ms increments (gates 2 through 7) to the full word (gate 8). Mixed-effects regression modeling was used to compare performance to our previous study which used single-talker stimuli (Wiener, Lee, & Tao, 2019). The results indicated that multi-talker speech caused both L1 and L2 listeners to rely greater on knowledge-based processing of tone. L1 listeners were able to draw on distributional knowledge of syllable-tone probabilities in early gates and switch to predominantly acoustic-based processing when more of the signal was available. In contrast, L2 listeners, with their limited experience with talker range normalization, were less able to effectively transition from probability-based to acoustic-based processing. Moreover, for the L2 listeners, the reliance on such distributional information for spoken word recognition appeared to be conditioned by the nature of the acoustic signal. Single-talker speech did not result in the same pattern of probability-based tone processing, suggesting that knowledge-based processing of L2 speech may only occur under certain acoustic conditions, such as multi-talker speech.

The success of particle detection in high energy physics colliders critically depends on the criteria for selecting a small number of interactions from an overwhelming number that occur in the detector. It also depends on the selection of the exact data to be analyzed and the techniques of analysis. The introduction of automation into the detection process has traded the direct involvement of the physicist at each stage of selection and analysis for the efficient handling of vast amounts of data. (...) This tradeoff, in combination with the organizational changes in laboratories of increasing size and complexity, has resulted in automated and semi-automated systems of detection. Various aspects of the semi-automated regime were greatly diminished in more generic automated systems, but turned out to be essential to a number of surprising discoveries of anomalous processes that led to theoretical breakthroughs, notably the establishment of the Standard Model of particle physics. The automated systems are much more efficient in confirming specific hypothesis in narrow energy domains than in performing broad exploratory searches. Thus, in the main, detection processes relying excessively on automation are more likely to miss potential anomalies and impede potential theoretical advances. I suggest that putting substantially more effort into the study of electron–positron colliders and increasing its funding could minimize the likelihood of missing potential anomalies, because detection in such an environment can be handled by the semi-automated regime—unlike detection in hadron colliders. Despite virtually unavoidable excessive reliance on automated detection in hadron colliders, their development has been deemed a priority because they can operate at currently highest energy levels. I suggest, however, that a focus on collisions at the highest achievable energy levels diverts funds from searches for potential anomalies overlooked due to tradeoffs at the previous energy thresholds. I also note that even in the same collision environment, different research strategies will opt for different tradeoffs and thus achieve different experimental outcomes. Finally, I briefly discuss current searches for anomalous process in the context of the previous analysis. (shrink)

Drawing on broad definitions of technology and engineering as well as precedents in the philosophical literature, this paper makes the novel argument that the purposeful design of one’s unique good life using existing philosophical concepts is an engineering activity. Whether as a metaphor or as an engineering activity in its own right, a sampling of important benefits and perspectives provided for well-being by the presented “life engineering” framework are highlighted. A key strength of the framework is the conceptual simplicity, with (...) minimal sacrifices in completeness or consistency. This necessitates a tradeoff of limited precision for any one practical implementation. Consistent conceptual definitions for wisdom, virtue and the good life are presented within an informative ethics. Only a descriptive evaluation to aid in conceptual understanding is discussed, no prescriptive normative evaluations are made. The good life is defined to be one in which the minimum requirements are met and then performance is good, but no attempt is made to define what is good. A fundamental limitation of the framework stems from the inherent focus of technology on human utility. Although no novel fundamental conclusions are drawn in this paper, the presented framework is demonstrated to correspond with numerous ethical precepts of many existing philosophical traditions.

Cognitive control refers to the regulation of mental activity to support flexible cognition across different domains. Cragg and Nation (2010) propose that the development of cognitive control in children parallels the development of language abilities, particularly inner speech. We suggest that children’s late development of cognitive control also mirrors their limited ability to revise misinterpretations of sentence meaning. Moreover, we argue that for certain tasks, a tradeoff between bottom-up (data-driven) and top-down (rule-based) thinking may actually benefit performance in both (...) children and adults. Specifically, we propose that a lack of cognitive control may promote important aspects of cognitive development, like language acquisition and creativity. (shrink)

The need to better balance the promotion of scientific and technological innovation with risk management for consumer protection has inspired several recent reforms attempting to make regulations more flexible and adaptive. The pharmaceutical sector has a long, established regulatory tradition, as well as a long history of controversies around how to balance incentives for needed therapeutic innovations and protecting patient safety. The emergence of disruptive biotechnologies has provided the occasion for regulatory innovation in this sector. This article investigates the regulation (...) of advanced biotherapeutics in the European Union and shows that it presents several defining features of an adaptive regulation regime, notably institutionalized processes of planned adaptation that allow regulators to gather, generate, and mobilize new scientific and risk evidence about innovative products. However, our in-depth case analysis highlights that more attention needs to be paid to the consequences of the introduction of adaptive regulations, especially for critical stakeholders involved in this new regulatory ecosystem, the capacity and resource requirements placed on them to adapt, and the new tradeoffs they face. In addition, our analysis highlights a deficit in how we currently evaluate the performance and public value proposition of adaptive regulations vis-à-vis their stated goals and objectives. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Analogy of Grace: Karl Barth’s Moral Theology by Gerald McKenny, and: Christian Ethics as Witness: Barth’s Ethics for a World at Risk by David HaddorffVictor ThasiahThe Analogy of Grace: Karl Barth’s Moral Theology Gerald McKenny New York: Oxford University Press, 2010. 310 pp. $120.00Christian Ethics as Witness: Barth’s Ethics for a World at Risk David Haddorff Eugene, OR: Cascade Books, 2010. 482 pp. $54.00Karl Barth’s theology remains (...) a resource for Christian ethics. Let me suggest why. Instead of marginalizing or bracketing out consideration of divine agency, Barth presupposes God’s past, present, and future action; God’s inalienable subjectivity and indissoluble over-againstness in relationship (irreducible, for example, to ecclesial action); and God’s ongoing judgment of good and evil, and thus of moral thought and practice. These presuppositions determine the method, structure, content, and purpose of his theology and ethics. His concept of grace consists of God accomplishing the good in our place and on our behalf, a perspective more substantive than supplementary in nature. Finally, his eschatological view of human freedom involves resistance and responsibility—the freedom to resist evil (having been delivered from the determination of evil by grace) and the freedom to witness to God’s action in faith, love, and hope in the world. Barth’s work serves the field of Christian ethics well, burdened as we are by unprecedented global awareness with its challenges and uncertainties.Two new books on Barth’s theology and ethics seek to increase our understanding of his work and engage contemporary Christian moral thought and practice. Gerald McKenny’s The Analogy of Grace is now the indispensable guide to Barth’s ethics. His exposition is comprehensive, critical, and contextual as it relates Barth’s dogmatics to current academic work in Christian ethics and moral philosophy. The tradeoff, however, is that it pays insufficient attention to the ecclesial, cultural, and political contexts for embodying Barth’s ethics. McKenny makes an important contribution to our understanding of Barth’s work. By closely reading primary texts and secondary literature, McKenny shows that many of Barth’s critics and friends continue to misunderstand [End Page 192] him by resolving the unresolvable, airbrushing ambiguities and thus converting Barth’s “strange” ethics into a more conventional moral theory. McKenny argues that it is precisely the strangeness of Barth’s theology—with all its implications—that continues to challenge and contribute constructively to contemporary Christian ethics.What is so strange and significant about Barth’s work? For McKenny, it is Barth’s claim that “God resolves on the good from eternity in the determination of humanity in Jesus Christ to commission and service as active witnesses of God’s glory; fulfills it in time in the incarnation, life, death, resurrection, and ascension of Jesus Christ, who performs this commission and service in place of all of humanity; and summons, empowers, and directs human beings in every time to correspond to this fulfillment in their conduct” (288). Thus, our action should be modeled on God’s action; it should be an analogy of grace. “The telos of God’s grace is realized,” McKenny concludes, “when human beings in their action become the image of God” (208). The Analogy of Grace traces the way Barth develops this ontological and analogical vision as McKenny differentiates Barth’s work from modern theories that presuppose that people are relatively capable of knowing and doing the good.McKenny suggests that there is a possible deficiency in the way Barth’s account of divine agency determines the form and content of his theology and ethics. Barth’s consistent opposition to moral theories that emphasize observable signs of moral progress in either self or society results in the “liability” of the “extraordinarily qualified affirmation he gives to visible human goodness” (223). McKenny asks if Barth “does justice to the work of the Holy Spirit in our lives” and “can make sense of the participation of our action in God’s action or of the way in which the Holy Spirit accomplishes this participation” (223). In other words, Barth’s “extraordinarily qualified affirmation” might neglect the work of the Spirit in... (shrink)

Critics of the organization of industrial work under capitalism have ranged from the “human relations” school to socio‐technical systems theorists and, most vociferously, to advocates of labor process theory (LPT). Their practical influence on management was small as long as production was rolling on and profits rolling in. When competition intensified, however, employers started to question old ideas and, abetted by the needs of new computerized technology, began to broaden jobs, allow workers greater discretion in their performance and involve (...) them in shop floor decision making. LPT, however, has not contributed to this evolution toward more satisfying work. This paper explains why this is so by exploring two major shortcomings of LPT. First and foremost is that LPT has ignored the efficiency of the work process, refusing to acknowledge the legitimacy of a tradeoff between work “goodness” and productivity.As a result, LPT has been unable to propose economically viable alternatives to existing job design and work organization. Second, LPT has identified management's goal in organizing work as gaining control of the process, when, in fact, it has been to make the process as economically efficient as possible. Thus, LPT could not see that, under changed circumstances, management might decentralize control toward the shop floor, if that might promote efficiency. LPT's founder, Harry Braverman, and his disciples believed that it was impossible to reform work under capitalism, but experience shows otherwise. (shrink)

Expert athletes are determined to make faster and better decisions, as revealed in several simple heuristic studies using verbal reports or micro-movement responses. However, heuristic decision-making experiments that require motor responses, also being considered as the embodied-choice experiments, are still underrepresented. Furthermore, it is less understood how decision time and confidence depend on the type of embodied choices players make. To scrutinize the decision-making processes, this study investigated the embodied choices of male athletes with different expertise in a close-to-real-life environment; (...) 22 elite, and 22 amateur team handball players performed a sport-specific embodied-choice test. Attack sequences were shown to the players, who had to choose between four provided options by giving a respective sport-specific motor response. We analyzed the frequencies of specific choices and the best choice, as well as the respective decision time and decision confidence. Elite and amateur players differed in the frequencies of specific choices, and elite players made the best choice more often. Slower decision times of elite players were revealed in specific choices and in best choices, the confidence of decisions was rated equally high by both player groups. Indications are provided that elite players make better choices rather slower, instead of faster. We suppose this is due to specific sensorimotor interactions and speed-accuracy-tradeoffs in favor of accuracy in elite players. Our findings extend expert decision-making research by using an embodied-choice paradigm, highlighting considerations of decision time and confidence in future experiments. (shrink)

The picture-word interference paradigm has been used to investigate the time course of processes involved in word retrieval, but is challenging to implement online due to dependence on measurements of vocal reaction time. We performed a series of four experiments to examine picture-word interference and facilitation effects in a form of covert picture naming, with and without gamification. A target picture was accompanied by an audio word distractor that was either unrelated, phonologically-related, associatively-related, or categorically-related to the picture. Participants were (...) instructed to judge whether the name of the target picture ended in the phoneme assigned to the block by pressing corresponding keys as quickly and accurately as possible. Experiments 1 and 2 successfully replicated categorical interference and phonological facilitation effects at different optimal stimulus-onset-asynchronies between words and pictures. Experiment 3 demonstrated that a key gamification feature motivated faster speed at the expense of accuracy in the gamified vs. experimental format of the task. Experiment 4 adopted the optimal SOAs and verified that the gamification reveals expected interference and facilitation effects despite the speed-accuracy tradeoff. These studies confirmed that categorical interference occurs earlier than phonological facilitation, while both processes are independent from articulation and inherent to word retrieval itself. The covert PWI paradigm and its gamification have methodological value for neuroimaging studies in which articulatory artifacts obscure word retrieval processes, and may be developed into potential online word-finding assessments that can reveal word retrieval difficulties with greater sensitivity.

Recent interest in the external validity of prediction models has produced many methods for finding predictive distributions that are invariant to dataset shifts and can be used for prediction in new, unseen environments. However, these methods consider different types of shifts and have been developed under disparate frameworks, making it difficult to theoretically analyze how solutions differ with respect to stability and accuracy. Taking a causal graphical view, we use a flexible graphical representation to express various types of dataset shifts. (...) Given a known graph of the data generating process, we show that all invariant distributions correspond to a causal hierarchy of graphical operators, which disable the edges in the graph that are responsible for the shifts. The hierarchy provides a common theoretical underpinning for understanding when and how stability to shifts can be achieved, and in what ways stable distributions can differ. We use it to establish conditions for minimax optimal performance across environments, and derive new algorithms that find optimal stable distributions. By using this new perspective, we empirically demonstrate that that there is a tradeoff between minimax and average performance. (shrink)

This work examines the importance of distinguishing different levels of psychological explanation and the primacy of the computational level over implementational levels. The framework of levels allows us to recognize the role of formal theories as tools for specifying reasoning tasks at the computational level. It is shown that formal specifications of reasoning tasks allow us to analyze the complexity of the specified tasks and also serve to define reasoning competence and performance errors. Complexity analysis helps us identify tractable, (...) practically significant, subclasses of inference. The identification of these subclasses provides useful ante hoc and post hoc specifications for AI programming projects and psychological modeling. Formalization and complexity analysis also enable us to examine tradeoffs between tractability and range of applicability of implementations of a reasoning task. It is undesirable to obtain tractability at the expense of limiting the applicability of a cognitive mechanism to an unreal situation or a toy domain. It is argued that this undesirable result can be avoided if we examine the structure of the environment in which a mechanism is supposed to work and the environmental assumptions that make the computation tractable. Finally, it is demonstrated that many problems the human mind needs to solve in normal environments are indeed tractable and that the mind is equipped with adaptive mechanisms to solve them efficiently. This demonstration undermines a skeptical challenge to human rationality based on claims that many problems are intractable and that the capacity of the human mind is limited. (shrink)

This paper addresses the phenomenon of incomplete preferences in disaster risk management. If an agent finds two options to be incomparable and thus has an incomplete preference ordering, i.e., neither prefers one option over the other nor finds them equally as good, it is not possible for the agent to perform a value tradeoff, necessary for an informed decision, between these two options. In this paper we suggest a way to model incomplete preference orderings by means of probabilistic preferences, and (...) how to reveal an agent’s incomplete preference ordering within a behaviorist framework.

Corporate social responsibility remains a topic of interest for both theory and practice due to its multifaceted avenues and potential for growth. We have chosen embedded CSR and peripheral CSR measures to evaluate how these activities affect the employee turnover intentions via a mediation mechanism of organizational citizenship behavior. In doing so, this study addresses important stakeholder concerns and provides meaningful managerial contributions for the employers to encourage more employee participation toward sustainable corporate performance. This study incorporates four hypotheses (...) that are tested in a structural equation modeling framework by employing Warp-PLS software. Data were collected from 297 employees working in firms that are renowned for their CSR initiatives. We found support for our key hypotheses leading to strong theoretical contributions to the stakeholder theory. We have addressed the main issues of stakeholders’ response to the CSR tradeoffs and have tried to develop a deeper understanding of managers in initiating peripheral and embedded CSR activities for their firms.

The threshold view says that a person forms an outright belief P if and only if her credence for P reaches a certain threshold. Using computer simulations, I compare different versions of the threshold view to understand how they perform under time pressure in decision problems.

A threshold view that performs well across diverse contexts is likely to be a cognitively flexible and context-dependent fusion (...) of several of the existing theories. The results of the simulations also cast doubts on the possibility of a threshold view that is both simple enough to streamline our reasoning while also allowing us to form good action-guiding beliefs.

The Expanse does not provide an easy answer to the vexing question on making a decision when competing, but considering conflicts of values on the show can help us reason about tough choices in real life. Sometimes, scientific progress conflicts with the prudential value of self‐preservation.

The idea that all these different kinds of value can be traded with a common currency is tempting. But contra Keats, beauty is not truth; and it certainly is not goodness, as Tolstoy says.

These characterizations are then used to examine the relationships between parameter precision and two types of generality. We show that several of these relationships exhibit (...) class='Hi'>tradeoffs and discuss what consequences those tradeoffs have for theoretical practice. (shrink)

This paper explores the space of possibilities for public justification in morally diverse communities. Moral diversity is far more consequential than is typically appreciated, and as a result, we need to think more carefully about how our standard tools function in such environments. I argue that because of this diversity, public justification can be divorced from any claim of determinateness. Instead, we should focus our attention on procedures—in particular, what Rawls called cases of pure procedural justice. I use a modified (...) form of the procedure “I cut, you choose” to demonstrate how perspectival diversity can make what looks like a simple procedure quite complex in practice. I use this to reframe disputes between classical liberal and contemporary liberal approaches to questions of public morality, arguing that classically liberal procedures, such as a reliance on the harm principle, can generate rather illiberal-looking outcomes when used in a morally diverse community. A seemingly less-principled approach, which simply balances burdens, appears to generate outcomes that look closer to what we would expect from classical liberalism. However, since both approaches are based on pure procedures that we can justify without reference to outcomes, it remains indeterminate which we ought to choose. (shrink)

Epistemic teleology is the view that (a) some states have fundamental epistemic value, and (b) all other epistemic value and obligation are to be understood in terms of promotion of or conduciveness to such fundamentally valuable states. Veritistic reliabilism is a paradigm case: It assigns fundamental value to true belief, and it makes all other assessments of epistemic value or justification in terms of the reliable acquisition of beliefs that are true rather than false. Teleology faces potentially serious problems from (...) cases of cross-propositional tradeoffs and cases of epistemic self-promotion. Both are cases in which committing some intuitive epistemic ill (such as believing against one’s evidence) promotes the greater epistemic good. It can seem that epistemic teleologies must incorrectly endorse intuitively unjustified beliefs as justified in such cases. This paper defends epistemic teleology on two fronts. First, I argue that the problems of tradeoffs and self-promotion do not affect minimally plausible epistemic teleologies. Second, I rehearse some of what I take to be the main reasons to prefer epistemic teleology to alternative views. A theme that develops along the way is that plausible teleologies evaluate belief-forming methods by appeal to their promotion of epistemic goals, but they evaluate individual beliefs by appeal to their causal histories. That is the feature that enables them to avoid tradeoff problems, without abandoning teleology and without resorting to ad hoc epicycles. (shrink)

I argue that bounded agents face a systematic accuracy-coherence tradeoff in cognition. Agents must choose whether to structure their cognition in ways likely to promote coherence or accuracy. I illustrate the accuracy-coherence tradeoff by showing how it arises out of at least two component tradeoffs: a coherence-complexity tradeoff between coherence and cognitive complexity, and a coherence-variety tradeoff between coherence and strategic variety. These tradeoffs give rise to an accuracy-coherence tradeoff because privileging coherence over complexity or strategic variety often (...) leads to a corresponding reduction in accuracy. I conclude with a discussion of two normative consequences for the study of bounded rationality: the importance of procedural rationality and the role of coherence in theories of bounded rationality.

The standard economic and ethical case in defense of sweatshops employs the standard of the “welfare of their workers and potential workers” to argue that sweatshop regulations harm the very people they intend to help. Scholars have recently contended that once the benefits and costs are balanced, regulations do, in fact, raise worker welfare. This paper describes the short and long-run tradeoffs associated with sweatshop regulation and then examines how reasonable constructions of measures of “worker welfare” would evaluate these (...) tradeoffs finding that the standard economic and ethical case against sweatshop regulations is well supported.

[Opinion] This aims to begin deliberation about investing in negative emissions technologies (NETs) by suggesting that the investment could be responsive to two particular values: need and efficiency—and that these values point us towards taking different actions. For negative emissions technologies, I suggest, we face a Need-Efficiency Tradeoff, i.e. a “NET effect”. This tradeoff also highlights several contrasts: responding to need focuses on regional and short-term moral considerations; responding to efficiency focuses on global and long-term moral considerations.
