This dissertation examines how we should respond to situations in which a person acts profoundly imprudently. We can, e.g., imagine the motorcyclist who prefers to drive without insurance and without a helmet. How should we, or the policy-makers, counter such imprudent activities performed by others? One option is that we do nothing, meaning that we do not interfere with other people’s imprudent behaviour, at the same time refraining from providing assistance in cases where the risk of the activities materialises. A (...) second option is to provide unconditional assistance to the person in need by taxing everyone. A third option is that we regulate the risky activity prior to the accident (e.g. by forcing the person to take out insurance, imposing security measures, or perhaps banning the activity in question). No matter what we choose, our choice seems to compromise at least one of the following moral considerations: i) satisfying sufficiency, ii) avoiding paternalism, or iii) internalising the costs associated with the risky activities (so that the persons performing the activities carry the relevant costs). For the same reason, it has been pointed out that together the three considerations constitute a trilemma, the so-called ‘imprudence trilemma.’ The dissertation argues that we should accept paternalism when people act so imprudently that they risk suffering serious, absolute deprivation as a result (i.e. in cases of relevance to the trilemma). That is not to say that we should always interfere when a person acts profoundly imprudently. The paternalistic view defended is that it is a good and relevant (but not necessarily decisive) reason in favour of interfering with a person’s voluntary choices that such interference will promote the person’s interests or well-being. Pace the anti-paternalistic view, I argue that such reasons should be included in the assessment of policies and actions that interfere with people’ liberty or autonomy. (shrink)

In the WebSurf task, humans forage for videos paying costs in terms of wait times on a time-limited task. A variant of the task in which demands during the wait time were manipulated revealed the role of attention in susceptibility to sunk costs. Consistent with parallel tasks in rodents, previous studies have found that humans preferred shorter delays, but waited longer for more preferred videos, suggesting that they were treating the delays economically. In an Amazon Mechanical Turk sample, we replicated (...) these predicted economic behaviors for a majority of participants. In the lab, participants showed susceptibility to sunk costs in this task, basing their decisions in part on time they have already waited, which we also observed in the subset of the mTurk sample that behaved economically. In another version of the task, we added an attention check to the wait phase of the delay. While that attention check further increased the proportion of subjects with predicted economic behaviors, it also removed the susceptibility to sunk costs. These findings have important implications for understanding how cognitive processes, such as the deployment of attention, are key to driving re-evaluation and susceptibility to sunk costs. (shrink)

Modal knowledge accounts that are based on standards possible-worlds semantics face well-known problems when it comes to knowledge of necessities. Beliefs in necessities are trivially sensitive and safe and, therefore, trivially constitute knowledge according to these accounts. In this paper, I will first argue that existing solutions to this necessity problem, which accept standard possible-worlds semantics, are unsatisfactory. In order to solve the necessity problem, I will utilize an unorthodox account of counterfactuals, as proposed by Nolan, on which we also (...) consider impossible worlds. Nolan’s account for counterpossibles delivers the intuitively correct result for sensitivity i.e. S’s belief is sensitive in intuitive cases of knowledge of necessities and insensitive in intuitive cases of knowledge failure. However, we acquire the same plausible result for safety only if we reject his strangeness of impossibility condition and accept the modal closeness of impossible worlds. In this case, the necessity problem can be analogously solved for sensitivity and safety. For some, such non-moderate accounts might come at too high a cost. In this respect, sensitivity is better off than safety when it comes to knowing necessities. (shrink)

It is proposed here that there is a sensitive period in the first two to three years of life during which humans acquire a basic knowledge of what foods are safe to eat. In support of this, it is shown that willingness to eat a wide variety of foods is greatest between the ages of one and two years, and then declines to low levels by age four. These data also show that children who are introduced to solids unusually late (...) have a narrower diet breadth throughout childhood, perhaps because the duration of the sensitive period has been shortened. By reducing the costs associated with learning, a sensitive period for food learning should be adaptive for any omnivore (including early humans) that remains in the same environment throughout its life.

The main goal of the article is a further development of the usage of income and comparable approaches to company valuation aimed at defining market capitalization sensitivity to value changing in the conditions of dynamization of internal and external business parameters. The relevance of the researched topic is determined by the importance of establishing the factors influencing the change in company market capitalization based on the synthesis of approaches to company valuation. To obtain the results of the study, the (...) following methods were used: structural and logical analysis – to improve the process approach to company valuation in the context of determining the impact of its change on market capitalization; discounted cash flow method (DCF-model) – to determine the value of the enterprise based on the income approach; comparable companies method – to determine the value of the company on the basis of a market approach; factor analysis method – to assess the impact of changes in value on company market capitalization; generalization and logical analysis – in conclusions building. The results of critical analysis of publications of domestic and foreign scientists on the application of company valuation methods identified the need of improvement the process approach to company valuation in the context of determining the impact of its change on the company market capitalization. To adequately assess company value, the use of a synthesis of income and market approaches is proposed. The implementation of the DCF-model and comparable companies valuation method while valuation of Private Joint-Stock Company “SKF Ukraine” allowed to establish that the greatest impact on the target metric (company market capitalization) has an average industry multiplier EV/EBITDA, terminal growth rate and weighted average cost of capital – 5.9 %, 3.2% and 2.7% respectively. The practical value of the results of the study is determined by the importance of forming a full analytical basis for establishing the attractiveness of the performance of joint-stock companies in the market and consolidating management decisionsin order to increase market capitalization.

According to evidentialist views, credence in a proposition p should be proportional to the degree of evidential support that one has in favor of p. However, empirical evidence suggests that our credences are systematically sensitive to practical factors. In this article, I provide a cost–benefit analysis of credences' practical sensitivity. The upshot of this analysis is that credences sensitive to practical factors fare better than practically insensitive ones along several dimensions. All things considered, our credences should be sensitive (...) to practical factors. (shrink)

This chapter teases out the implications of the hypothesis that assertion’s epistemic norm is set in a context-sensitive fashion, by appeal to what is mutually believed in context. In particular, it is argued that while these implications are substantial, they can be made to square with the main contention in the first eight chapters of the book. That is, they cohere with the norm-based account offered for what is called assertion’s philosophical significance. The process of bringing this out incorporates a (...) response to various objections to the context-sensitivity of the standard of assertion’s norm. One key implication is that standard accounts of sincerity in assertion, as requiring belief in what was asserted, are false. (shrink)

It is generally accepted that morally justified healthcare rationing must be non-discriminatory and cost-effective. However, given conventional concepts of cost-effectiveness, resources spent on disabled people are spent less cost-effectively, ceteris paribus, than resources spent on non-disabled people. Thus, it is reasonable to assume that standard cost-effectiveness discriminates against the disabled. Call this thedisability discrimination problem.Part of the disability discrimination involved in cost-effectiveness stems from the way in which health-related quality of life is accounted for and (...) measured. This paper offers and defends a patient-sensitive account of health-related quality of life, which can effectively make cost-effectiveness less discriminatory against the disabled and thus more morally justified.

The prevalence of non-communicable diseases, the related increased medical costs, and the recent public health emergency bring out more forcefully pre-existing dilemmas of distributive justice in the healthcare context. Under this reality, would it be justified to hold people responsible for their taken lifestyle decisions, or would it constitute an instance of unjustified disrespectful treatment? From a respect-based standpoint, one could argue that a responsibility-sensitive healthcare system morally disrespects the imprudent ones engaging in disadvantageous differential treatment to their detriment. In (...) contrast, however, we might also have luck egalitarian reasons that explain why this differential treatment is not unjust. Luck egalitarianism is a responsibility-sensitive theory of distributive justice, which argues that it is bad if some people are worse off than others through no voluntary fault of their own. In this paper, I clarify the concerns about disrespect raised against the luck egalitarian viewpoint and offer possible respect-based reasons for why this might not be the case grounded in deontological concepts. First, I employ a revised Double-effect case to support responsibility-sensitive rationing. In the last part of the paper, these are further supported through the Kantian Formula of Humanity supplemented by the concept of duties. (shrink)

This paper engages with the problem of toxic speech online and suggests remedies inspired by the value-sensitive design literature (VSD), suggesting that the designers of online platforms should explore methods of adding friction to online conversations. Second, this paper examines a historical case of designing a communications platform to offer methods to users to inculcate norms of acceptable behavior by introducing friction into synchronous conversations. This is the case of America Online (AOL) Instant Messenger, also known as AIM, which included (...) a feature whereby users could “warn” other users, attaching a cost to, and thus disincentivizing, certain kinds of speech. The nuances of the design of this feature make it especially well-suited as a subject of study in value-sensitive design as it seems to be the product of significant reflection and foresight by its designers. In the course of examining this case, this paper proposes two novel and generalizable processes of integrating values into the design of technology, inspired by the approach of value-sensitive design: a “method of decomposition,” reconstructing a user journey in order to identify possible moments of intervention; and an iterative “Innovation–Abuse–Innovation” branching diagram, which systematizes the process of anticipating abuse cases and designing responses to them. These methods build upon recent work in the literature on operationalizing ethical values in the design process. I close by illustrating the flexibility and generalizability of these methods and speculating on how they might be applied to contemporary platforms. (shrink)

The UK government has put lateral flow antigen tests (LFATs) at the forefront of its strategy to scale-up testing in the coronavirus pandemic. However, evidence from a pilot trial using an LFAT to identify asymptomatic infections in the community suggested that the test missed over half of the positive cases in the tested population. This raises the question of whether it can be ethical to use an inaccurate test to guide public health measures. We begin by explicating different dimensions of (...) test accuracy (sensitivity, specificity and predictive value), and why they matter morally, before highlighting key data from the Liverpool pilot. We argue that the poor sensitivity of the LFAT in this pilot trial suggests that there are important limitations to what we can expect these tests to achieve. A test with low sensitivity will provide false-negative results, and in doing so generate the risk of false assurance and its attendant moral costs. However, we also suggest that the deployment of an insensitive but specific test could identify many asymptomatic carriers of the virus who are currently being missed under existing arrangements. Having outlined ways in which the costs of false reassurance could potentially be mitigated, we conclude that the use of an insensitive LFAT in mass testing may be ethical if (1) it is used predominantly to identify positive cases, (2) it is a cost-effective method of achieving that goal and (3) if other public health tools can effectively prevent widespread false reassurance.

This study provides novel evidence of the impact of corporate social responsibility (CSR) on investment sensitivity to cash flows. We posit that CSR affects investment–cash flow sensitivity (ICFS) through information asymmetry and agency costs, commonly viewed as the two channels through which investment responds to the availability of internal cash flows. We find that CSR performance leads to a decrease in ICFS. We further find that ICFS decreases (increases) when CSR strengths (concerns) increase. Finally, we find that the (...) effect of CSR on ICFS is driven by the areas Community, Diversity, and Human Rights. In sum, the findings of this study stress the relevance of CSR—in particular, of CSR activities that extend beyond compliance behavior and reflect what is desired by society—in reducing market frictions and improving firms’ access to financial capital.

Can firms overcome credit constraints with a corporate culture of high integrity? We empirically address this question by studying their investment–cash flow sensitivities. We identify firms with a culture of integrity through textual analysis of public documents in a sample of Chinese listed firms and also through corporate culture statements. Our results show that firms with an integrity-focused culture have lower investment–cash flow sensitivity, even after we address endogeneity concerns. However, we also find that for the culture to reduce (...) the investment–cash flow sensitivity, external stakeholders must be able to verify this culture through a low information asymmetry environment. Overall, our findings show that a corporate culture of high integrity can mitigate a firm’s external transaction costs. (shrink)

To evaluate the performance of rural land circulation mode through the analytic network hierarchy process, based on the results of the performance evaluation with analytic network process, we implemented efficiency analysis on five types of rural land circulation mode by two improved efficiency analytic procedures. Finally, we implemented sensitivity analysis for each criterion layer of the evaluation index system with the performance evaluation data, interpreted five types of rural land circulation mode from three perspectives including benefits, costs, and risks (...) with sensitivity analysis results, and drew related conclusions including higher revenue which will lead to smaller difficulty of the rural land circulation. Cost variables were negative variables of the selected rural land circulation mode, and higher risk would lead to the greater difficulty of rural land circulation and related conclusions. (shrink)

We formulate and analyze the dynamics of an influenza pandemic model with vaccination and treatment using two preventive scenarios: increase and decrease in vaccine uptake. Due to the seasonality of the influenza pandemic, the dynamics is studied in a finite time interval. We focus primarily on controlling the disease with a possible minimal cost and side effects using control theory which is therefore applied via the Pontryagin’s maximum principle, and it is observed that full treatment effort should be given (...) while increasing vaccination at the onset of the outbreak. Next, sensitivity analysis and simulations (using the fourth order Runge-Kutta scheme) are carried out in order to determine the relative importance of different factors responsible for disease transmission and prevalence. The most sensitive parameter of the various reproductive numbers apart from the death rate is the inflow rate, while the proportion of new recruits and the vaccine efficacy are the most sensitive parameters for the endemic equilibrium point.

This article critically examines the proposal that the word "racism" should be restricted to the most egregious of racial ills. It argues that the costs of restricting the scope of the term in this way are too great and that the proposal gives too much weight to white sensitivities.

Previous work on individual differences has revealed limitations in the ability of existing measures (e.g., working memory) to predict language processing. Recent evidence suggests that an individual's sensitivity to detect the statistical regularities present in language (i.e., “chunk sensitivity”) may significantly modulate online sentence processing. We investigated whether individual chunk sensitivity predicted the online processing of gender cues, a core linguistic feature of Spanish. In a self‐paced reading task, we examined native speakers’ processing of relative clauses in (...) which gender cues were variably exploited to induce processing costs. Even after considering the effect of working memory and cognitive control, the results revealed a significant effect of chunking ability in modulating online sentence processing. Critically, higher‐chunking ability speakers’ reading times showed online sensitivity to core linguistic cues online; while low‐chunking ability readers showed no sensitivity to manipulations, indicating shallow real‐time processing of their native language.

Freedom of information laws promote transparency by permitting individuals and organizations to obtain government documents. However, exemptions from disclosure are necessary to protect privacy and to permit government officials to deliberate freely. Deliberative language is often the most challenging and burdensome exemption to detect, leading to high processing costs and delays in responding to open-records requests. This paper describes a novel deliberative-language detection model trained on a new annotated training set. The deliberative-language detection model is a component of a decision-support (...) system for open-records requests under the US Freedom of Information Act, the FOIA Assistant, that ingests documents responsive to an open-records requests, suggests passages likely to be subject to deliberative language, privacy, or other exemptions, and assists analysts in rapidly redacting suggested passages. The tool’s interface is based on extensive human-factors and usability studies with analysts and is currently in operational testing by multiple US federal agencies. (shrink)

The plant efficiency of a nuclear fusion power plant is considered. During nominal operation, the plant efficiency is determined by the thermodynamic efficiency and the recirculated power fraction. However, on average the reactor operates below the nominal power, even when the long shutdown periods for large maintenance are left outside the averaging. Hence, next to the recirculated power fraction the capacity factor must be factored in. An expression for the plant efficiency which incorporates both factors is given. It is shown (...) that the combination of high recirculated power fraction and a low capacity factor, results in poor plant efficiency. This is due to the fact that in a fusion reactor the recirculated power remains high if it runs at reduced output power. It is argued that, at least for a first generation of power plants, this combination is likely to occur. Worked out example calculations are given for the models of the power plant conceptual study. Finally, the impact on the competitiveness of fusion on the energy market is discussed. This analysis stresses the importance of the development of plant designs with low recirculated power fraction.

Introduction Families of patients with dementia may need support in difficult end-of-life decision making. Such guidance may be culturally sensitive. Methods To support families in Canada, a booklet was developed to aid decision making on palliative care issues. For reasons of cost effectiveness and promising effects, we prepared for its implementation in Italy, the Netherlands and Japan. Local teams translated and adapted the booklet to local ethical, legal and medical standards where needed, retaining guidance on palliative care. Using qualitative (...) content analyses, we grouped and compared adaptations to understand culturally sensitive aspects. Results Three themes emerged: (1) relationships among patient, physician and other professionals—the authority of the physician was more explicit in adapted versions; (2) patient rights and family position—adding detail about local regulations; and (3) typology of treatments and decisions. Considerations underlying palliative care decisions were detailed (Dutch and Italian versions), and the Japanese version frequently referred to professional and legal standards, and life-prolongation was a competing goal. Text on artificial feeding or fluids and euthanasia was revised extensively. Conclusions Providing artificial feeding and fluids and discussing euthanasia may be particularly sensitive topics, and guidance on these subjects needs careful consideration of ethical aspects and possible adaptations to local standards and practice. The findings may promote cross-national debate on sensitive, core issues regarding end-of-life care in dementia. (shrink)

Background To determine whether fetal care paediatric and maternal–fetal medicine specialists harbour differing attitudes about pregnancy termination for congenital fetal conditions, their perceived responsibilities to pregnant women and fetuses, and the fetus as a patient and whether self-perceived primary responsibilities to fetuses and women and views about the fetus as a patient are associated with attitudes about clinical care.Methods Mail survey of 434 MFM and FCP specialists.Results MFMs were more likely than FCPs to disagree with these statements : ‘the presence (...) of a fetal abnormality is not an appropriate reason for a couple to consider pregnancy termination’ ; ‘the effects that a child born with disabilities might have on marital and family relationships is not an appropriate reason for a couple to consider pregnancy termination’ ; and ‘the cost of healthcare for the future child is not an appropriate reason for a couple to consider pregnancy termination’. 65% MFMs versus 47% FCPs disagreed that their professional responsibility is to focus primarily on fetal well-being. Specialists did not differ regarding the fetus as a separate patient. Responses about self-perceived responsibility to focus on fetal well-being were associated with clinical practice attitudes.Conclusions Independent of demographic and sociopolitical characteristics, FCPs and MFMs possess divergent ethical sensitivities regarding pregnancy termination, pregnant women and fetuses, which may influence clinical care.

I defend the thesis that friendship can constitutively require epistemic irrationality against a recent, forceful challenge, raised by proponents of moral and pragmatic encroachment. Defenders of the “encroachment strategy” argue that exemplary friends who are especially slow to believe that their friends have acted wrongly are simply sensitive to the high prudential or moral costs of falsely believing in their friends’ guilt. Drawing on psychological work on epistemic motivation (and in particular on the notion of “need for closure”), I propose (...) a different picture of what friendship requires in the doxastic realm. I argue that contrary to what the encroachment strategy suggests, exemplary friends’ belief formation ought not be guided by a concern with accuracy or error avoidance, but instead by a need to avoid a “specific closure” – namely, a need to avoid concluding in their friends’ guilt. I propose that exemplary friendship often generates a defeasible, doxastic obligation to exemplify such a need, despite its inherent corrupting effects on exemplary friends’ epistemic faculties.

Background: Omalizumab, an anti-immunoglobulin E antibody, reduces exacerbations and symptoms in uncontrolled allergic asthma. The study objective was to estimate the costs and consequences of omalizumab compared to usual care from a US payer perspective. Methods: We estimated payer costs, quality-adjusted survival (QALYs), and the incremental cost-effectiveness ratio (ICER) of omalizumab compared to usual care using a state-transition simulation model that included sensitivity analyses. Every 2 weeks, patients could transition between chronic asthma and exacerbation health states. The best (...) available evidence informed the clinical and cost input estimates. Five years of omalizumab treatment followed by usual care was assumed to estimate a lifetime horizon. Omalizumab responders (60.5% of treated) were modeled as a separate scenario where nonresponders reverted back to usual care after 16 weeks of active treatment. Results: The mean lifetime discounted costs and QALYs were $83 400 and 13.87 for usual care and $174 500 and 14.19 for omalizumab plus usual care resulting in $287 200/QALY (95% interval: $219 300, $557 900). The ICER was $172 300/QALY when comparing omalizumab to usual care in the responder scenario. One-way sensitivity analyses indicated that the results were sensitive to the difference in treatment-specific utilities for the chronic state, exacerbation-associated mortality, omalizumab price, exacerbation rates, and response definition. Conclusions: The results suggest that adding omalizumab to usual care improves QALYs at an increase in direct medical costs. The cost-effectiveness of omalizumab is similar to other chronic disease biologics. The value increases when omalizumab response is used to guide long-term treatment. (shrink)

When assessing the cost effectiveness of health care programmes, health economists typically presume that distant events should be given less weight than present events. This article examines the moral reasonableness of arguments advanced for positive discounting in cost-effectiveness analysis both from an intergenerational and an intrapersonal perspective and assesses if arguments are equally applicable to health and monetary outcomes. The article concludes that behavioral effects related to time preferences give little or no reason for why society at large (...) should favour the present over the future when making intergenerational choices regarding health. The strongest argument for discounting stems from the combined argument of diminishing marginal utility in the presence of growth. However, this hinges on the assumption of actual growth in the relevant good. Moreover, current modern democracy may be insufficiently sensitive to the concerns of future generations. The second part of the article categorises preference failures (which justify paternalistic responses) into two distinct groups, myopic and acratic. The existence of these types of preference failures makes elicited time preferences of little normative relevance when making decisions regarding the social discount rate, even in an intrapersonal context. As with intergenerational discounting, the combined arguments of growth and diminishing marginal utility offer the strongest arguments for discounting in the intrapersonal context. However, there is no prima facie reason to assume that this argument should apply equally to health and monetary values. To be sure, selecting an approach towards discounting health is a complex matter. However, the life-or-death implications of any approach require that the discussion not be downplayed to merely a technical matter for economists to settle. (shrink)

Since commencing its illegal invasion in 2022, the Russian military and authorities have committed numerous war crimes against the people of Ukraine. These include the mutilation and execution of combatants; the torture, kidnapping, forced expulsion, rape, and massacre of civilians; and indiscriminate attacks on densely populated areas. In this essay, I evaluate the strategic implications of this misconduct, focusing exclusively on Western responses. I argue that war crimes can and often do negatively impact the strategic goals of the perpetrator, but (...) whether and how this occurs is rarely governed exclusively by the offending action. Western perceptions of battlefield atrocity, shaped as they are by identity, race, and politics, may radically shift from one context to another. In the case of the Russia-Ukraine war, the status of both the participants and the conflict itself has helped inculcate a particular sensitivity among Western actors to the battlefield criminality of Russia. Drawing on evidence from the 2022 Bucha massacre and the ongoing bombing of Ukrainian civilians, I argue that Russian misconduct has consolidated Western support for the Ukrainian military effort, politically, diplomatically, and materially.

Critical care nursing is central to intensive care delivery, yet its costs and burdens remain largely invisible in low‐ and lower‐middle‐income countries. As critical care services expand in response to epidemiological transitions and global health emergencies, economic evaluations increasingly guide policy and resource allocation. However, prevailing health economic frameworks privilege infrastructure, technology, and physician‐led interventions while treating nursing labor as a fixed or residual input. Using a feminist political economy and social reproduction lens, this discursive paper argues that the key (...) research gap lies not only in limited data but also in systematic undervaluation of critical care nursing as gendered, socially necessary labor. Drawing on feminist economics, labor theory, and health workforce research, this paper examines how dominant costing and cost‐effectiveness approaches obscure the variable and value‐generating nature of nursing work. Nursing labor misclassification can distort incremental cost‐effectiveness ratios, creating a false appearance of efficiency by excluding key labor inputs. These omissions shift costs onto nurses through work intensification, burnout, moral distress, migration, and onto households through unpaid caregiving and out‐of‐pocket spending. The paper proposes a feminist health economics research agenda prioritizing labor‐sensitive costing, workforce well‐being, gender‐responsive analysis, household cost accounting, and nurse‐led research supporting equitable and sustainable critical care systems.

What is the proper role of cost-benefit analysis in understanding the tort concept of negligence or reasonable care? A straightforward question, you might think. But it is a question that manages to elicit groans of exasperation from those on both sides of the controversy. For most utilitarians and adherents to law and economics, the answer is obvious: to say that people should not be negligent is to say that they should minimize the sum of the costs of accidents and (...) the costs of preventing accidents. Under the economic formulation of the famous Learned Hand test, they should take a precaution if but only if the marginal costs (or burden, B) of that precaution are less than its marginal benefits (in the form of reduced risks of injury, measured by multiplying the probability (P) of the injury times the magnitude (L) of the injury if it occurs). If B>PxL, it would be absurd to require the greater expenditure, B. For many advocates of a fairness, corrective justice, rights-based, or contractualist perspective, the opposite answer is equally obvious. Permitting a person to impose risks of harm on others merely because he would thereby obtain a benefit (or would otherwise incur a burden) greater than the discounted value of the harm he might inflict, amounts to authorizing him to dump the costs of his risky activities on innocent victims. To permit this type of sacrifice of individuals on the altar of aggregate social welfare is morally abhorrent. Both sets of criticism have important elements of truth. Neither an unqualified cost-benefit analysis nor an unqualified rights-based rejection of tradeoffs is defensible - either as a description of tort doctrine and practice or as a normative prescription. However, a qualified (sensitive) consequentialist approach can accommodate legitimate criticisms of cost-benefit analysis: the consequentialist can launder preferences, and can consider the distribution of risk both in the social welfare calculus and in determining whether to compensate. At the same time, a qualified (tough-minded) deontological approach can accommodate the legitimate need to recognize tradeoffs: the deontologist can permit intrapersonal but not interpersonal aggregation of risks and benefits, can apply the concept of threshold deontology to risky activity, and can consider individual rather than population risk. I conclude that the formulation of the Learned Hand test found in the Restatement Third of Torts is broad enough to encompass each of these qualified approaches. (shrink)

The ArgumentIn this we explore some of the ways in which a state scientific laboratory (Daresbury SERC) reacted to the rtetoric and forces of the marketpace in the 1980s. We describe laboratory attempts to create what we call “good customers” while converting itself into a “good seller” by developing a particulat set of costing practicting that were closely related to the implementation of a management accounting system. Finally, we consider how Daresbury response to “market forces” influenced scintific and organzational practice, (...) and arsponse that the social technologies of governmentality performed by accountancy — but also by scientific and bureaucratic practice are complex, discursively heterogeneou, and used in context-sensitive ways.

This study investigates how consumer online complaints, an influential form of negative electronic word-of-mouth (eWOM), affect corporate labor cost stickiness. Using a large dataset of complaints against Chinese listed companies, we find that a higher complaint volume significantly increases labor cost stickiness. This effect is driven by two sequential mechanisms: reputation governance, through which firms are compelled to maintain workforce stability under reputational threat, and strategic rigidity, through which path-dependent investment in complaint-handling resources gradually generates structural rigidity. This (...) relationship remains robust after a series of sensitivity tests, including alternative variable specifications, a quasi-natural experiment based on the difference-in-differences method, and the instrumental variable (IV) approach. Furthermore, the effect is more pronounced in firms with higher reputation risks and greater internal adjustment costs. Notably, although complaint-driven labor cost stickiness initially appears as a passive defensive response, it generates positive long-term performance consequences. By linking digital marketing phenomena to internal cost structures, this study reveals the substantial financial consequences of online consumer complaints and bridges marketing and management accounting research. More broadly, this study highlights the responsibility dilemma faced by firms in the digital age: under consumer complaint pressure, firms passively bear higher labor costs and lose short-term operating flexibility. Yet this response may generate positive long-term performance consequences. (shrink)

The distinction between access consciousness and phenomenal consciousness is a subject of intensive debate. According to one view, visual experience overflows the capacity of the attentional and working memory system: We see more than we can report. According to the opposed view, this perceived richness is an illusion—we are aware only of information that we can subsequently report. This debate remains unresolved because of the inevitable reliance on report, which is limited in capacity. To bypass this limitation, this study utilized (...) color diversity—a unique summary statistic—which is sensitive to detailed visual information. Participants were shown a Sperling-like array of colored letters, one row of which was precued. After reporting a letter from the cued row, participants estimated the color diversity of the noncued rows. Results showed that people could estimate the color diversity of the noncued array without a cost to letter report, which suggests that color diversity is registered automatically, outside focal attention, and without consuming additional working memory resources.

When healthcare resources are scarce, they ought to be distributed fairly across society. For some theories of distribution, an assessment of individual health risk is required for a fair distribution of both healthcare resources and burdens. Despite this requirement, prevailing theories underappreciate the cost of information on health risk. Information relevant to health risk will be ignored when these costs are too high, leading to a form of discrimination that I term “information discrimination”. This leads to a potential source (...) of unfairness for any health system that aims to distribute the burdens of healthcare across individuals according to their expected health states. Individuals whose risks are cheap to identify will have their risks personalized whereas individuals whose risks are expensive to identify will have their risks spread across society or the collective. This paper discusses the implications of this unfairness on two types of distributive theories in healthcare: responsibility‐sensitive and responsibility‐insensitive. (shrink)

Introduction Social anxiety disorder (SAD) symptoms are maintained by cognitive biases, which are overestimations of the severity and likelihood of negative social events (cost/probability biases), and by sensitivity to rewards and punishments that are determined according to behavioral inhibition/behavioral activation systems (BIS/BAS). Cost/probability biases might activate the behavioral immune system and exacerbate the avoidance of social events. Earlier studies have proposed that low BIS or high BAS decrease SAD symptoms; BIS/BAS may even change the effects of cognitive (...) biases on SAD symptoms. Hence, the current study investigates the interaction effects of BIS/BAS and cost/probability biases on SAD symptoms. Method Seventy-six Japanese undergraduate students completed the Japanese version of the Liebowitz Social Anxiety Scale (LSAS), which comprises Fear and Avoidance subscales, the BIS/BAS Scale, and the Social Cost Probability Scale. Results A multiple regression analysis was performed to examine whether cost/probability biases, BIS/BAS, and their interactions affected SAD symptoms; following this, the main effects of cost bias and BIS were determined for LSAS-Fear (β =.64, p <.001; β =.33, p <.01) and LSAS-Avoidance (β =.49, p <.001; β =.35, p <.01). The interaction effect between cost bias and BAS was significant for LSAS-Avoidance (β = −.32, p <.05). Simple slope analysis showed that the slope of cost bias was significant for low-BAS individuals (β =.77, p <.001) but not for high-BAS individuals (β = −.21, n.s.). The interaction effect between probability bias and BAS was significant for LSAS-Avoidance (β =.40, p <.01) as well. Further, simple slope analysis revealed that the slope of probability bias was significant for low-BAS individuals (β = −.53, p <.05) but not for high-BAS individuals (β =.17, n.s.). Discussion The study found interesting results with respect to the avoidance of social events. Low-BAS individuals with high cost or low probability biases regarding social events may have a tendency to avoid social events. In contrast, if high-BAS individuals overestimate the cost of social events or underestimate the probability of social events, their anticipation of rewards might prevent them from avoiding social events.

Due to the intense selection pressure against inbreeding, humans are expected to possess psychological adaptations that regulate mate choice and avoid inbreeding. From a gene’s-eye perspective, there is little difference in the evolutionary costs between situations where an individual him/herself is participating in inbreeding and inbreeding among other close relatives. The difference is merely quantitative, as fitness can be compromised via both routes. The question is whether humans are sensitive to the direct as well as indirect costs of inbreeding. Using (...) responses from a large population-based sample (27,364 responses from 2,353 participants), we found that human motivations to avoid inbreeding closely track the theoretical costs of inbreeding as predicted by inclusive-fitness theory. Participants were asked to select in a forced choice paradigm, which of two acts of inbreeding with actual family members they would want to avoid most. We found that the estimated fitness costs explained 83.6% of participant choices. Importantly, fitness costs explained choices also when the self was not involved. We conclude that humans intuit the indirect fitness costs of mating decisions made by close family members and that psychological inbreeding avoidance mechanisms extend beyond self-regulation.

From building a new piece of furniture to replacing a lightbulb, people must often figure out how to assemble an object from its parts. Although these physical assembly problems take on many different forms, they also pose common challenges. Chief among these is the question of how to break a complex problem down into subproblems that are easier to solve. What principles determine why some strategies for decomposing a problem are favored over others? Here, we investigate the decisions that people (...) make when considering different visual subgoals in the context of attempting to build a series of virtual block towers. We hypothesized that people favor subgoals achieving a balance between how much progress the subgoals would help achieve toward the final goal and how effortful they would be to solve. We tested this hypothesis by defining several computational models of planning and subgoal selection, then evaluating how well these models predicted human planning and subgoal selection behavior on the same problems. Our results suggest that participants rapidly differentiated the computational costs of otherwise similarly ambitious subgoals, and used these judgments to drive subgoal selection. Moreover, our findings are consistent with the possibility that participants were not only sensitive to the immediate computational costs associated with solving the very next subgoal, but also future costs that might be incurred when attempting the rest of the problem. Taken together, these results contribute to our understanding of how humans make efficient use of cognitive resources to solve complex, grounded planning problems. (shrink)

Explainable Artificial Intelligence (XAI) is increasingly championed for its potential to enhance transparency and accountability in clinical decision support. However, emerging evidence reveals a critical trade-off: these benefits may not come without significant costs. While deep neural networks achieve remarkable accuracy in tasks like diabetic retinopathy diagnosis (AUROCs near 0.91) (Aziz et al. in medRxiv https://doi.org/10.1101/2024.08.10.24311735, 2024), the pursuit of interpretability often necessitates simpler models, leading to a notable performance drop (AUROCs of 0.78–0.82), potentially compromising patient outcomes. Furthermore, post-hoc explanation (...) techniques like SHAP (Lundberg in A unified approach to interpreting model predictions. arXiv:1705.07874, 2017) and LIME (Ribeiro et al. in “Why should I trust you?” Explaining the predictions of any classifier. In Proceedings of the 22nd ACM SIGKDD International Conference on knowledge discovery and data mining, pp 1135–1144, 2016), while offering insights into complex models, can more than double inference times (Abgrall et al. in Crit Care 28:301, 2024), significantly impeding workflow efficiency, particularly in time-sensitive clinical environments. Adding to these concerns, the integration of XAI can elevate operational costs by 10-15%, potentially contributing to clinician burnout and hindering widespread adoption (Dhiman et al. in Information 14:541, 2023; Hulsen in AI 4:652–666, 2023). While these challenges are significant, they must be weighed against potential long-term benefits in diagnostic accuracy, workflow efficiency, and regulatory compliance, as documented in recent implementation studies (Davenport and Kalakota in Future Healthc J 6:94–98, 2019; Sayres et al. in Ophthalmology 126:552–564, 2019). The multifaceted challenges highlight the inherent tension between transparency, performance, and cost-effectiveness in the application of AI within healthcare. This review synthesizes the evidence for these trade-offs, drawing upon technical findings on performance degradation, clinical data illustrating workflow disruptions, and economic analyses quantifying the financial burdens associated with XAI. We demonstrate that relying solely on post-hoc explanation methods can undermine the predictive power of high-performing models by approximately 3.8% (Amann et al. in BMC Med Inform Decis Mak 20:310, 2020) and add 30–40 s to each patient case. By examining promising emerging solutions, including hybrid models that integrate interpretable components directly into their architectures (Koh et al. in Concept bottleneck models. In: Proceedings of the International Conference on machine learning, PMLR, pp. 5338–5348. https://proceedings.mlr.press/v119/koh20a.html, 2020), and by advocating for clinician-centered evaluation frameworks, we aim to identify viable pathways to maintain diagnostic accuracy without incurring prohibitive costs or unacceptable latency. Ultimately, we argue that aligning AI design with the practical demands of clinical workflows, establishing standardized metrics for interpretability, and embedding transparency directly within model architectures are crucial steps towards realizing trustworthy and cost-efficient decision support. Through this pragmatic lens, balancing inherent interpretability with computational efficiency, and considering both immediate costs and long-term benefits, XAI can transition from a theoretical ideal to a sustainable and truly transformative asset for patient care.

Since the last generation medical ethics has seen a remarkable shift from benign medical paternalism to patient rights and autonomy. Whereas once it might have been acceptable for doctors to decide, largely on their own, what was in the best interests of their patients, today senior health professionals are expected to make decisions jointly both with patients or their carers and with other health professionals. Patient autonomy and justice, and not simply beneficence, are usually thought to be crucial to medical (...) ethics today.Although I strongly support this shift in medical ethics, I believe it is important to recognise that it has some cost to medical professionals, to patients and even at times to the National Health Service . Medical paternalism, when it was genuinely benign, did have some benefits both for doctors and for their patients. Yet precisely because most of us are no longer prepared to be at the receiving end of such paternalism, these particular benefits are now largely lost to us.The new joint statement, Decisions Relating to Cardiopulmonary Resuscitation,1 illustrates this point well. At the outset it admits that “health professionals are aware that decisions about attempting resuscitation raise very sensitive and potentially distressing issues for the patient and people emotionally close to the patient”. It was because of these sensitive and potentially distressing issues that it was once thought acceptable to make do not attempt resuscitation orders without consulting either patients or their families and with the knowledge that the latter would probably never discover that such orders had ever been made. Now, however, health workers are warned frankly that they “should remember …. (shrink)

Making proper decisions in today’s complex world is a challenging task for decision makers. A promising approach that can support decision makers to have a better understanding of complex systems is agent-based modeling. ABM has been developing during the last few decades as a methodology with many different applications and has enabled a better description of the dynamics of complex systems. However, the prescriptive facet of these applications is rarely portrayed. Adding a prescriptive decision-making aspect to ABM can support the (...) decision makers in making better or, in some cases, optimized decisions for the complex problems as well as explaining the investigated phenomena. In this paper, first, the literature of DM with ABM is inquired and classified based on the methods of integration. Performing a scientometric analysis on the relevant literature lets us conclude that the number of publications attempting to integrate DM and ABM has not grown during the last two decades, while analysis of the current methodologies for integrating DM and ABM indicates that they have serious drawbacks. In this regard, a novel nature-inspired model articulation called optimal agent framework has been proposed to ameliorate the disadvantages and enhance the realization of proper decisions in ABM at a relatively low computational cost. The framework is examined with the Bass diffusion model. The results of the simulation for the customized model developed by OAF have verified the feasibility of the framework. Moreover, sensitivity analyses on different agent populations, network structures, and marketing strategies have depicted the great potential of OAF to find the optimal strategies in various stochastic and unconventional conditions which have not been addressed prior to the implementation of the framework.

Effective supply chain management relies on strong cooperation between manufacturers and retailers. Both can enhance their profits by boosting market demand through offering discounts and increasing marketing expenditure. This research aims to develop inventory models considering annual demand dependent on the discount given by the manufacturer to the customer on the maximum retailer price and the advertising expenditure of the retailer. We develop inventory models in both non-cooperative and cooperative environments to optimize profits. Inventory level and discounts are considered decision (...) variables for the manufacturer, while EOQ and marketing expenditure are the decision variables for the retailer. Solution process and sensitivity analysis are performed using numerical examples. Concavity of the profit functions with respect to all the decision variables is discussed using analytical methods. Results show that annual market, EOQ, inventory level, demand, and profit increase in cooperative environments. A non-cooperative environment is favourable for the manufacturer. (shrink)

Levine et al.’s resource-rational contractualism (RRC) models moral judgment as a cost-sensitive approximation to ideal bargaining among stakeholders. We identify three strategies agents use to reduce moral costs by outsourcing or bypassing virtual bargaining: strategic delegation, diffusion of responsibility, and coalitional boundary-setting. We propose extending RRC with parameters for agency transfer, responsibility tracking, and stakeholder inclusion to better capture real-world moral decision-making.

Software defects prediction at the initial period of the software development life cycle remains a critical and important assignment. Defect prediction and correctness leads to the assurance of the quality of software systems and has remained integral to study in the previous years. The quick forecast of imperfect or defective modules in software development can serve the development squad to use the existing assets competently and effectively to provide remarkable software products in a given short timeline. Hitherto, several researchers have (...) industrialized defect prediction models by utilizing statistical and machine learning techniques that are operative and effective approaches to pinpoint the defective modules. Tree family machine learning techniques are well-thought-out to be one of the finest and ordinarily used supervised learning methods. In this study, different tree family machine learning techniques are employed for software defect prediction using ten benchmark datasets. These techniques include Credal Decision Tree, Cost-Sensitive Decision Forest, Decision Stump, Forest by Penalizing Attributes, Hoeffding Tree, Decision Tree, Logistic Model Tree, Random Forest, Random Tree, and REP-Tree. Performance of each technique is evaluated using different measures, i.e., mean absolute error, relative absolute error, root mean squared error, root relative squared error, specificity, precision, recall, F-measure, G-measure, Matthew’s correlation coefficient, and accuracy. The overall outcomes of this paper suggested RF technique by producing best results in terms of reducing error rates as well as increasing accuracy on five datasets, i.e., AR3, PC1, PC2, PC3, and PC4. The average accuracy achieved by RF is 90.2238%. The comprehensive outcomes of this study can be used as a reference point for other researchers. Any assertion concerning the enhancement in prediction through any new model, technique, or framework can be benchmarked and verified. (shrink)

Some mutual funds not only apply the usual asset management and custodial fees, but also front loads and redemption fees as a kind of ‘toll charge’ payable on entering and/or leaving the fund. The aim of this work is to examine the implications of the different loads and fees applied to mutual fund investors in the Spanish market. The results show that there is a relationship between the various charges and fees. The fact that load fund companies charge higher management (...) and custody fees proves the potential of the fund companies to impose higher fees on a segment of the clientele. The investors in load funds, which tend to be large in number of shareholders and belonging to banks and savings banks, are small investors who show a low cost sensitivity. A lower level of financial sophistication may be the reason for the apparent lower price awareness. The problem is that the investors in load funds are not financially compensated for the extra cost represented by the front‐load and redemption fees. The only beneficiary seems to be the financial institution itself. On this view, the survival of load funds seems to depend on the lack of financial sophistication of their clientele, combined with market inefficiencies. It is worth asking about the ethics of a situation of market segmentation that allows managing institutions to benefit from the segment of the least sophisticated investors. (shrink)

Professor Hall is to be congratulated on his thoughtful analysis of an issue that, as he rightly suggests, “is one of the most important issues that will confront health care tort law throughout the remainder of the century.”’ He argues that malpractice law currently can accommodate considerable latitude both for a conservative streamlining of medical practices in general and for a cost-sensitivity in individual treatment decisions. And he further argues that existing tort principles, such as the locality rule, (...) can comfortably be stretched to embrace still greater room for economics in the medical standard of care. I quite agree.Unfortunately, Hall's arguments do not go nearly far enough, for they are framed around a seriously oversimplified picture of the economic changes that are revolutionizing medicine in the United States. He envisions a fairly uniform, global set of resource constraints that generally pressure physicians to conserve on care—pressures that tort law can then encompass equally globally as it accepts more cost-efficient standards of care. However, neither the changing economics of medicine nor the resulting jurisprudential challenges are anywhere near this generalized. (shrink)

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)

Most engineers Fwork within social structures governing and governed by a set of values that primarily emphasise economic concerns. The majority of innovations derive from these loci. Given the effects of these innovations on various communities, it is imperative that the values they embody are aligned with those societies. Like other transformative technologies, artificial intelligence systems can be designed by a single organisation but be diffused globally, demonstrating impacts over time. This paper argues that in order to design for this (...) broad stakeholder group, engineers must adopt a systems thinking approach that allows them to understand the sociotechnicity of artificial intelligence systems across sociocultural domains. It claims that value sensitive design, and envisioning cards in particular, provides a solid first step towards helping designers harmonise human values, understood across spatiotemporal boundaries, with economic values, rather than the former coming at the opportunity cost of the latter.

Time theft is a costly burden on organizations. However, there is limited knowledge about why time theft occurs. To advance this line of research, this conceptual paper looks at the association between organizational injustice and time theft from identity, moral, and equity perspectives. This paper proposes that organizational injustice triggers time theft through decreased organizational identification. It also proposes that moral disengagement and equity sensitivity moderate this process such that organizational identification is less likely to mediate among employees with (...) high moral disengagement and more likely to mediate among employees who are equity sensitives and entitleds.
