Not all of the studies cited in the target article as evidence that fluctuating asymmetry (FA) predicts male mating success demonstrate that the observed asymmetry is, in fact, FA. FA is a population-level pattern of differences between sides. Unless the population-level distributional criteria of bilateral traits are reported, the meaning of asymmetry in individuals is unknown.

ABSTRACT:Utilitarianism is commonly defined in very different ways, sometimes in a single text. There is wide agreement that it mandates maximizing some kind of good, but many formulations also require a pattern of distribution. The most common of these take utilitarianism to characterize right acts as those that achieve “the greatest good for the greatest number.” This paper shows important ambiguities in this formulation and contrasts it (on any plausible interpretation of it) with the kinds of utilitarian views actually defended (...) by major proponents of utilitarianism. The aim is not to defend any of these views but to formulate them in a way that facilitates using them—or, more likely, some revised version suggested by the paper—in guiding decisions in business. The analysis provided here should also facilitate appraisal of utilitarianism, contribute to clarity in discussions of business ethics, and suggest a range of ethical standards that merit consideration for certain kinds of decision. If the results of the analysis are correct, a distributive reading of utilitarianism is at best misleading as a representation of its central thrust; it should not be described as the view that ethics calls for achieving “the greatest good for the greatest number”; and, understood as its major proponents take it, utilitarianism differs more from Kantian ethics than distributive readings imply and is more difficult to defend than it appears to be when viewed as intrinsically distributive.

In this paper I proceed on the assumption that moral philosophers can and should contribute to the resolution of perplexing moral problems. The ones considered here relate to decisions concerning the distribution of scarce medical resources as between those in need of treatment. I draw on considerations of egalitarianism and concern for the maximization of the use of scarce resources in the task of satisfying basic human needs (such as for good health). I propose certain principles and offer some supporting (...) suggestions as guidelines or rules for medical decisions with a view to providing a helpful decision procedure for the various persons (doctors, community panels and so on) whose task it is to make the life-or-death decisions involved in allocating certain scarce medical resources. -/- .

Recent disputes over whether older people should pay more for health insurance, or receive lower priority for transplantable organs, highlight broader disagreements regarding the legality of using age-based criteria in health care. These debates will likely intensify given the changing age structure of the American population and the turmoil surrounding the financing of American health care. This Article provides a comprehensive examination of the legality and normative desirability of age-based criteria. I defend a distributive justice approach to (...) age-based criteria and contrast it with two prevailing theoretical approaches to age-based criteria, nondiscrimination and discretion. I propose a detailed normative framework for the use of age-based criteria in health care, the lifetime justice approach, that considers the future life patients can gain from treatment and the past years of life they already have experienced. -/- This paper is available by open access from the Boston College Law School Digital Commons.

Due to constraints on institutional capacity and financial resources, the road to universal health coverage (UHC) involves difficult policy choices. To assist with these choices, scholars and policy makers have done extensive work on criteria to assess the substantive fairness of health financing policies: their impact on the distribution of rights, duties, benefits and burdens on the path towards UHC. However, less attention has been paid to the procedural fairness of health financing decisions. The Accountability for Reasonableness Framework (A4R), (...) which is widely applied to assess procedural fairness, has primarily been used in priority-setting for purchasing decisions, with revenue mobilization and pooling receiving limited attention. Furthermore, the sufficiency of the A4R framework’s four criteria (publicity, relevance, revisions and appeals, and enforcement) has been questioned. Moreover, research in political theory and public administration (including deliberative democracy), public finance, environmental management, psychology, and health financing has examined the key features of procedural fairness, but these insights have not been synthesized into a comprehensive set of criteria for fair decision-making processes in health financing. A systematic study of how these criteria have been applied in decision-making situations related to health financing and in other areas is also lacking. This paper addresses these gaps through a scoping review. It argues that the literature across many disciplines can be synthesized into 10 core criteria with common philosophical foundations. These go beyond A4R and encompass equality, impartiality, consistency over time, reason-giving, transparency, accuracy of information, participation, inclusiveness, revisability and enforcement. These criteria can be used to evaluate and guide decision-making processes for financing UHC across different country income levels and health financing arrangements. The review also presents examples of how these criteria have been applied to decisions in health financing and other sectors. (shrink)

Conceptual spaces are a frequently applied framework for representing concepts. One of its central aims is to find criteria for what makes a concept natural. A prominent demand is that natural concepts cover convex regions in conceptual spaces. The first aim of this paper is to analyse the convexity thesis and the arguments that have been advanced in its favour or against it. Based on this, I argue that most supporting arguments focus on single-domain concepts (e.g., colours, smells, shapes). (...) Unfortunately, these concepts are not the primary examples of natural concepts. Building on this observation, the second aim of the paper is to develop criteria for natural multi-domain concepts. The representation of such concepts has two main aspects: features that are associated with the concept and the probabilistic correlation pattern which the concept captures. Conceptual spaces, together with probabilistic considerations, provide a helpful framework to approach these aspects. With respect to feature representation, the existence of characteristic features (i.e., that apples have a specific taste) is essential. Moreover, natural concepts capture peaks of a probabilistic distribution over complex spaces. They carve up nature at its joints, that is, at areas with no or low probabilistic density. This last aspect is shown to be closely related to the convexity demand. (shrink)

Artificial agents have become increasingly prevalent in human social life. In light of the diversity of new human–machine interactions, we face renewed questions about the distribution of moral responsibility. Besides positions denying the mere possibility of attributing moral responsibility to artificial systems, recent approaches discuss the circumstances under which artificial agents may qualify as moral agents. This paper revisits the discussion of how responsibility might be distributed between artificial agents and human interaction partners (including producers of artificial agents) and raises (...) the question of whether attributions of responsibility should remain entirely on the human side. While acknowledging a crucial difference between living human beings and artificial systems culminating in an asymmetric feature of human–machine interactions, this paper investigates the extent to which artificial agents may reasonably be attributed a share of moral responsibility. To elaborate on criteria that can justify a distribution of responsibility in certain human–machine interactions, the role of types of criteria (interaction-related criteria and criteria that can be deferred from socially constructed responsibility relationships) is examined. Thereby, the focus will lay on the evaluation of potential criteria referring to the fact that artificial agents surpass in some aspects the capacities of humans. This is contrasted with socially constructed responsibility relationships that do not take these criteria into account. In summary, situations are examined in which it seems plausible that moral responsibility can be distributed between artificial and human agents. (shrink)

This paper stems from the current global worsening of the scarcity of resources for healthcare, which will deepen even more in future public emergencies. This justifies strengthening the reflection on the allocation of resources which, in addition to considering technical issues, should also involve ethical concerns. The two plans in which the allocation of resources develops—macro and micro—are then systematized, both requiring the identification of ethical criteria for the respective complex decision-making. Then, we describe how the complexity at the (...) macro level focuses on the joint consideration of the rectitude of the principles, the goodness of the ends, and the integrity—respectively the deontological, teleological, and procedural perspectives; and at the micro level, it focuses in prioritizing people, which can result in the exclusion of some, as happened with the elderly during peaks of COVID-19. The main objective of this article is to show that, in public health emergency situations, in which the daily criteria for prioritizing access to health care are not efficient, it is possible not only to ration the available means but also to rationalize them. We argue that rationing and rationalization are different concepts, entail different consequences, have different ethical foundations, and draw different guidelines for patient care. We apply them to the distribution of intensive care and vaccines to the elderly thus demonstrating the ethically legitimate domain of implementation of each of these two prioritization criteria. We conclude that rationalization respects more strictly the core ethical principles of our common morality. (shrink)

Two criteria, one for distributive and one for commutative justice are formulated, the latter applying to cases of free cooperation. Both criteria follow Aristotle's idea of proportional equality which in the first case is equality in the fulfillment of legitimate claims, in the second case equality of the gains derived from cooperation. The theory of social welfare functions is employed in the definition of the two criteria, but such functions are applied only to morally or legally (...) justified interests. A theory of justice only has to say how to satisfy conflicting legitimate claims, it is argued, but not what interests are justified in some given context. (shrink)

This study addresses the problem of output quasisynchronization for coupled complex-valued memristive reaction-diffusion complex networks via the distributed event-triggered control scheme. First, by using the separate method, set value mapping, and intermediate value theorem, the complex-valued memristive reaction-diffusion complex networks can be transferred into two semi-uncertain real-valued reaction-diffusion complex networks. Second, a distributed output piecewise event-triggered control scheme with spatial sampled-data is first proposed including a spatial sampling event-triggered generator and spatiotemporal sampling state feedback controller. Furthermore, this scheme can effectively (...) save the measurement resources and lower the update rate of controllers in spatial and time domain. Third, the synchronization analysis is considered by utilizing an appropriate Lyapunov function, the Halanay inequality, and the improved Wirtinger inequality. Subsequently, several output event-triggered quasisynchronization criteria are derived. The relations among event trigger conditions, spatial sampling interval, convergence rate, and control gain are given by rigorous mathematical derivation. Finally, multiple simulations are compared to substantiate the validation of the OPETC scheme. (shrink)

How should states and international organizations allocate global health resources? This paper examines proposals for distributing these resources in the literature. First, we look at the literature on the metrics for measuring what matters and consider how they might be modified to avoid some common objections—e.g., that these measures discriminate against the disabled or fail to give due weight to helping the young (or old) or those in present (or future) generations. Second, we canvas existing approaches to evaluating allocations of (...) health‐related resources utilizing such measures and advance a new way of doing so. We suggest that it is important to provide substantive arguments for directly evaluating alternative allocations, but there is also room for deliberation about fair procedures for selecting allocation criteria and securing just outcomes.

Bilattices, introduced by Ginsberg as a uniform framework for inference in artificial intelligence, are algebraic structures that proved useful in many fields. In recent years, Arieli and Avron developed a logical system based on a class of bilattice-based matrices, called logical bilattices, and provided a Gentzen-style calculus for it. This logic is essentially an expansion of the well-known Belnap–Dunn four-valued logic to the standard language of bilattices. Our aim is to study Arieli and Avron’s logic from the perspective of abstract (...) algebraic logic . We introduce a Hilbert-style axiomatization in order to investigate the properties of the algebraic models of this logic, proving that every formula can be reduced to an equivalent normal form and that our axiomatization is complete w.r.t. Arieli and Avron’s semantics. In this way, we are able to classify this logic according to the criteria of AAL. We show, for instance, that it is non-protoalgebraic and non-self-extensional. We also characterize its Tarski congruence and the class of algebraic reducts of its reduced generalized models, which in the general theory of AAL is usually taken to be the algebraic counterpart of a sentential logic. This class turns out to be the variety generated by the smallest non-trivial bilattice, which is strictly contained in the class of algebraic reducts of logical bilattices. On the other hand, we prove that the class of algebraic reducts of reduced models of our logic is strictly included in the class of algebraic reducts of its reduced generalized models. Another interesting result obtained is that, as happens with some implicationless fragments of well-known logics, we can associate with our logic a Gentzen calculus which is algebraizable in the sense of Rebagliato and Verdú . We also prove some purely algebraic results concerning bilattices, for instance that the variety of distributive bilattices is generated by the smallest non-trivial bilattice. This result is based on an improvement of a theorem by Avron stating that every bounded interlaced bilattice is isomorphic to a certain product of two bounded lattices. We generalize it to the case of unbounded interlaced bilattices. (shrink)

During the first wave of the COVID-19 pandemic in Italy, practitioners had to make tragic decisions regarding the allocation of scarce resources in the ICU. The Italian debate has paid a lot of attention to identifying the specific regulatory criteria for the allocation of resources in the ICU; in this paper, however, we argue that deciding such criteria is not enough for the implementation of fair and transparent allocative decisions. In this respect, we discuss three ethical issues: (a) (...) in the Italian context, the treating physician, rather than a separate committee, was generally the one responsible for the allocation decision; (b) although many allocative guidelines have supported moral equivalence between withholding and withdrawing treatments, some health professionals have continued to consider it a morally problematic aspect; and (c) the health workers who have had to make the aforementioned decisions or even only worked in ICU during the pandemic often experienced moral distress. We conclude by arguing that, even if these problems are not directly related to the above-mentioned issues of distributive justice, they can nevertheless directly affect the quality and ethics of the implementation of allocative criteria, regardless of those chosen.

Until recently, few people would have doubted that the idea of distributive justice is old, indeed ancient. Several authors have now challenged this assumption. Most prominently, Samuel Fleischacker argued that distributive justice originates in the eighteenth century. If accurate, this would upset much of what we have taken for granted about an important part of the history of Western political thought. However, the thesis is manifestly flawed; and since it has already proven influential, it is important to set (...) the record straight. We will focus on the principle of extreme necessity, developed in twelfth- and thirteenth-century canon law, and subsequently adopted in civil law. Despite its immense importance for the history of political thought, the principle is barely known, and much less discussed. We briefly characterize the main tenets of the principle and show that it meets all the criteria to count as a principle of distributive justice. (shrink)

This self-contained one page paper produces one valid two-premise premise-conclusion argument that is a counterexample to the entire three traditional rules of distribution. These three rules were previously thought to be generally applicable criteria for invalidity of premise-conclusion arguments. No longer can a three-term argument be dismissed as invalid simply on the ground that its middle is undistributed, for example. The following question seems never to have been raised: how does having an undistributed middle show that an argument's conclusion (...) does not follow from its premises? This result does nothing to vitiate the theories of distribution developed over the period beginning in medieval times. What it does vitiate is many if not all attempts to use distribution in tests of invalidity outside of the standard two-premise categorical arguments—where they were verified on a case-by-case basis without further theoretical grounding. In addition it shows that there was no theoretical basis for many if not all claims of fundamental status of rules of distribution. These results are further support for approaching historical texts using mathematical archeology. (shrink)

We report the results of a questionnaire study on the fair distribution of indivisible goods. We collected data from three different subject pools, first- and second- year students majoring in economics, law students, and advanced economics students with some background knowledge of fairness theories. The purpose of this study is to assess the empirical relevance of various fairness criteria such as inequality aversion, the utilitarian principle of maximizing the sum of individual payoffs, the Rawlsian “maximin” principle of maximizing the (...) payoff of the worst-off individual, and the criterion of envy-freeness (in the sense of Foley 1967).

Definition of the problem: Even after the new German legislation about organ donors and transplantation (“information solution”), the question of criteria for distributing the organs is still not solved. The various alternatives to solve this problem face different social acceptance and economic efficiency.Arguments: Medical criteria (e.g. HLA compatibility) and non-medical criteria (e.g. willingness to pay of the patients) are valued on the basis of generally accepted objectives (e.g. equal access to health services or low costs). As an (...) innovative form of organ distribution systems the club solution is introduced. It allows the donor to realise preferences regarding use of the organs.Conclusion: Scoring systems may help to increase the transparency of organ allocation. From an economic point of view medical criteria have to be weighted more than non-medical criteria. (shrink)

Proceeding on a limited number of general, widely accepted equity criteria, we develop a proposal for distributing common resources. In particular, the proposed fair division mechanism is individually rational, envy-free, Pareto-efficient and satisfies the stand alone test, which follows as a minimum requirement from the resource and population monotonicity criteria. Applied to international climate policy, the thrust of this proposal is that the South should initially be fully compensated for the greenhouse gas abatement measures it is to undertake (...) as a result of efficiency considerations.

: If we were asked to draw a graph to represent the distribution of consciousness in the world around us based on objective criteria, we would definitely be in trouble. The two objective parameters that have been traditionally considered as a guide – the complexity of behavior and brain size – lead to paradoxical conclusions and turn out to be unsatisfactory, to say the least. We need to find novel, reliable metrics. However, these can be identified, validated and calibrated (...) only if we first tackle seriously the problem of recognizing consciousness in our fellow humans, a task which is far from being obvious. Keywords: Consciousness; Animal; Brain; Behaviour; Coma La distribuzione della coscienza: un difficile diagramma cartesiano Riassunto: Se ci chiedessero di tracciare un grafico per rappresentare la distribuzione della coscienza nel mondo che ci circonda su una base oggettiva, ci troveremmo sicuramente in difficoltà.

È necessario individuare altre misure.

Advances in psychopharmacology raise the prospects of enhancing neurocognitive functions of humans by improving attention, memory, or mood. While general ethical reflections on psychopharmacological enhancement have been increasingly published in the last years, ethical criteria characterizing physicians’ role in neurocognitive enhancement and guiding their decision-making still remain highly unclear. Here it will be argued that also in the medical domain the use of cognition-enhancing drugs is not intrinsically unethical and that, in fact, physicians should assume an important role in (...) gating their usage. For finding normative orientation, concepts of disease, normality or medicine will not be helpful since—due to their cryptonormative nature—they rather hamper than allow targeted discussion and decision-making. As an alternative, the common and widely accepted bioethical criteria of beneficence, non-maleficence, autonomy and distributive justice allow a clinically applicable, highly differentiated context- and case-sensitive approach. By embedding decision-making in a participative physician–patient relationship extrinsic objections against neurocognitive enhancement (e.g. invalid perceptions about efficacy, benefit or risk; questionable voluntariness; restrained decision-making capacity) can be curtailed.

A manifestly covariant relativistic statistical mechanics of a system of N indistinguishable events with motion in space-time parametrized by an invariant “historical time” τ is considered. The relativistic mass distribution for such a system is obtained from the equilibrium solution of the generalized relativistic Boltzmann equation by integration over angular and hyperangular variables. All the characteristic averages are calculated. Expressions for the pressure and the energy density are found, and the relativistic equation of state is obtained. Validity criteria are (...) defined. The Galilean limit is considered; the theory is shown to pass over to the usual nonrelativistic statistical mechanics of indistinguishable particles. Anti-events are introduced; for an event-anti-event system the equation of state p, ρ ∝ T 6 is found, which gives the value of the sound velocity c 2 = 0.20, in agreement with the “realistic” equation of state suggested by Shuryak for hot hadronic matter.

It is evident that the problem of global climate change is closely bound up with questions of distributional justice, both intra- and intergenerational. Questions of justice are raised by two kinds of burdens: reductions in the emission of greenhouse gases, and the financial and knowledge transfers necessary to enable the poorest countries to compensate the harms suffered by the ongoing process. Both burdens involve considerable costs and opportunity costs. On the backdrop of a prioritarian version of utilitarianism, it is argued (...) that the answer should be a split strategy. While reduction of emissions should be based on the polluter-pays principle, obligations of compensation should be based on the criteria of overall economic strength. (shrink)

This study focuses on a third-party perspective of idiosyncratic deals. More specifically, we look into the differential judgments co-workers make about i-deals in their work environment, as well as their reactions. Based on equity theory, we examine to what extent the content of the i-deal and the work context explain co-worker judgments regarding i-deal fairness in addition to subsequent voice behavior. A vignette study with 1988 respondents shows that when i-deals are considered distributively unfair, co-workers try to restore equity through (...) voice behavior, thereby making the i-deal less effective. Furthermore, i-deals spark more distributive injustice perceptions and voice behavior in a highly interdependent work context. Finally, on average, financial bonuses were considered most distributively unfair and, thus, trigger more voice behavior. These results have important implications for i-deal literature as they uncover the criteria that co-workers use to judge i-deals and shape their reactions. (shrink)

Many have argued that individuals should receive income in proportion to their contribution to society. Others have believed that it would be fairer if people received income in proportion to the effort they expend in so contributing, since people have much greater control over their level of effort than their productivity. I argue that those who believe this are normally also committed, despite appearances, to increasing the social product — which undermines any sharp distinction between effort- and productivity-based distributive (...) proposals. However, effort-based proposals do emphasise more the importance of people having control over factors affecting their income. The second set of problems I consider is how to implement policies which hold true to this emphasis. I show that there are major problems with the accuracy of using any objective criteria to measure the level of effort a person is expending. Moreover, once any such criteria are employed the problem of ‘moral hazard’arises because people modify their behaviour in such a way as to maximise their income while minimising their effort. This violates the original motivation for using effort. Because of this and other empirical considerations, I argue that productivity may well be a better criterion on which to distribute income even if one is motivated by the same concerns which have prompted effort-based proposals.

Normative-based distributional comparisons across countries and over time build upon the assumption that individuals are selfish. However, there is a consolidated evidence that individuals also care about what others have. In this paper, we propose a framework for comparing and ranking distributions that includes non-individualistic possibilities. Specifically, we consider ranking criteria that account, in one case, for the feeling of compassion and, in the other case, for the feeling of envy. These feelings are generated respectively by those having lower (...) resources and those having higher resources. We illustrate our framework using CNEF data for Australia, Korea, Germany, Switzerland, and the US and show that accounting for the presence of compassion and envy might lead to different welfare rankings.

Next SectionBackground International and national agencies play a major role in setting HIV care-and-treatment priorities in low-income-countries. Little is known about priority setting at lower health-system levels. The objective of this article is to explore experiences of HIV priority decisions, at what levels these decisions are made and how they might influence the distribution of health benefits in a high-endemic region in Tanzania. Methods This is a qualitative study using observations, key documents and semistructured focus-group and individual interviews (43) with (...) health workers, patients and administrators at one regional and one district hospital. The analysis was based on an editing analysis style. Results Health workers did not perceive themselves as bedside rationing agents and they reported following national recommendations and felt they have little impact on important priority decisions. Health benefit distributions were largely determined by priority decisions made at a national level. External factors, such as eligibility criteria, inadequate funding and barriers to access seemed to play a major role in the actual distribution of health services and benefits in the region. Patient groups who were actually given high priority were the sickest patients, those living near a facility and those who could afford long journeys and frequent visits. Low-priority groups were those experiencing other co-morbidities or treatment failure, children, asymptomatic patients and the poorest. Conclusions/significance The interaction of priority setting across health-system levels and their impact on distribution of health outcomes in the population has been underestimated. The distributional pattern of health outcomes calls for further normative assessment. (shrink)

The skewness of a distribution, a poorly-defined term, is conventionally deemed to be invariant under linear transformations. A comparison is made of three criteria of it: the sign of odd central moments; the several relationships of the mean, the median and the mode; and asymmetry proper which is the set of ratios of the probability densities of all pairs of points equidistant above and below some arbitrary point, usually the principal mode. Some useful general relationships are discussed. The skeness (...) of convolutions is briefly discussed. A class of distributions is identified for which the skewness of the minimum ofk competing processes is independent ofk. It has importance in the parametric study of survivorship. (shrink)

With the rapid growth of informatics systems’ technology in this modern age, the Internet of Things (IoT) has become more valuable and vital to everyday life in many ways. IoT applications are now more popular than they used to be due to the availability of many gadgets that work as IoT enablers, including smartwatches, smartphones, security cameras, and smart sensors. However, the insecure nature of IoT devices has led to several difficulties, one of which is distributed denial-of-service (DDoS) attacks. IoT (...) systems have several security limitations due to their disreputability characteristics, like dynamic communication between IoT devices. The dynamic communications resulted from the limited resources of these devices, such as their data storage and processing units. Recently, many attempts have been made to develop intelligent models to protect IoT networks against DDoS attacks. The main ongoing research issue is developing a model capable of protecting the network from DDoS attacks that is sensitive to various classes of DDoS and can recognize legitimate traffic to avoid false alarms. Subsequently, this study proposes combining three deep learning algorithms, namely recurrent neural network (RNN), long short-term memory (LSTM)-RNN, and convolutional neural network (CNN), to build a bidirectional CNN-BiLSTM DDoS detection model. The RNN, CNN, LSTM, and CNN-BiLSTM are implemented and tested to determine the most effective model against DDoS attacks that can accurately detect and distinguish DDoS from legitimate traffic. The intrusion detection evaluation dataset (CICIDS2017) is used to provide more realistic detection. The CICIDS2017 dataset includes benign and up-to-date examples of typical attacks, closely matching real-world data of Packet Capture. The four models are tested and assessed using Confusion Metrix against four commonly used criteria: accuracy, precision, recall, and F-measure. The performance of the models is quite effective as they obtain an accuracy rate of around 99.00%, except for the CNN model, which achieves an accuracy of 98.82%. The CNN-BiLSTM achieves the best accuracy of 99.76% and precision of 98.90%. (shrink)

The COVID-19 pandemic has been overwhelming public health-care systems around the world. With demand exceeding the availability of medical resources in several regions, hospitals have been forced to invoke triage. To ensure that this difficult task proceeds in a fair and organised manner, governments scrambled experts to draft triage guidelines under enormous time pressure. Although there are similarities between the documents, they vary considerably in how much weight their respective authors place on the different criteria that they propose. Since (...) most of the recommendations do not come with ethical justifications, analysing them requires that one traces back these criteria to their underlying theories of distributive justice. In the literature, COVID-19 triage has been portrayed as a value conflict solely between utilitarian and egalitarian elements. While these two accounts are indeed the main antipodes, I shall show that in fact all four classic theories of distributive justice are involved: utilitarianism, egalitarianism, libertarianism, and communitarianism. Detecting these in the documents and classifying the suggested criteria accordingly enables one to understand the balancing between the different approaches to distributive justice—which is crucial for both managing the current pandemic and in preparation for the next global health crisis.

To carry out an ethnographic study on the work process in the sterilization unit of a hospital in Catalonia, we found the socially distributed cognition approaches of Hutchins and Kirsh useful. However, these approaches lack sufficient explanation on three important issues: the pragmatic criteria for identifying and delimiting a relevant unit of analysis and therefore the setting and contexts of the work process; the mechanisms and results of reciprocal influences between these levels of analysis; and the relation between these (...) levels. Therefore, we added several new elements to these approaches, in addition to Layder's model of contexts with some important modifications, with the aim of offering an interactive, cognitive and social proposal of analysis that clarifies these three issues, allowing a more exhaustive and broader empirical analysis that captures better the ‘social’ dimension embedded in the work processes.

The conception of social justice as equality is defended in this paper by examining what may appear to be two inegalitarian conceptions of justice, as distribution according to desert and as distribution according to need. It is argued that claims of just entitlement arise within a context of reciprocal co-operation for mutual benefit. Within such a context there are special cases where it can be said that those who contribute more deserve more, and that those who need more should get (...) more, but those claims themselves presuppose a norm of equal contribution and equal benefit.

There is an underappreciated disconnect between the ultimate values that lie at the heart of contemporary theories of distributive justice, and the practice of state institutions. State institutions deliver “intermediate goods” – goods such as health-care, education, housing, transportation, and the like – that are instrumental to a society being distributively just, but that do not in an of themselves constitute criteria of justice. Researchers who have emphasized the “social determinants of health” provide an insight that, when generalized, (...) point us in a direction that theorists of distributive justice should follow, that of attending not just to the instrinsic value of intermediate goods, but also to their causal contributions to realizing the values that theories of distributive justice make central. “Platforms”, which represent principle-driven attempts at designing compossible policies that attend both to the causal and to the intrinsic value of intermediate goods, should be given more importance within theories of distributive justice if such theories are to be policy-relevant, for they connect the ultimate values of these theories to the practices of state institutions.

The European Commission’s distribution key for refugees across the EU is wanting in many respects. Two LSE researchers defend an alternative key based on pragmatic and realistic criteria. The outcome is sometimes surprising.

We give a decision procedure for the ∀∃-theory of the weak truth-table (wtt) degrees of the recursively enumerable sets. The key to this decision procedure is a characterization of the finite lattices which can be embedded into the r.e. wtt-degrees by a map which preserves the least and greatest elements: a finite lattice has such an embedding if and only if it is distributive and the ideal generated by its cappable elements and the filter generated by its cuppable elements (...) are disjoint. We formulate general criteria that allow one to conclude that a distributive upper semi-lattice has a decidable two-quantifier theory. These criteria are applied not only to the weak truth-table degrees of the recursively enumerable sets but also to various substructures of the polynomial many-one (pm) degrees of the recursive sets. These applications to the pm degrees require no new complexity-theoretic results. The fact that the pm-degrees of the recursive sets have a decidable two-quantifier theory answers a question raised by Shore and Slaman in [21]. (shrink)

Recent advances in machine learning methods have created opportunities to eliminate unfairness from algorithmic decision making. Multiple computational techniques (i.e., algorithmic fairness criteria) have arisen out of this work. Yet, urgent questions remain about the perceived fairness of these criteria and in which situations organizations should use them. In this paper, we seek to gain insight into these questions by exploring fairness perceptions of five algorithmic criteria. We focus on two key dimensions of fairness evaluations: distributive (...) fairness and procedural fairness. We shed light on variation in the potential for different algorithmic criteria to facilitate distributive fairness. Subsequently, we discuss procedural fairness and provide a framework for understanding how algorithmic criteria relate to essential aspects of this construct, which helps to identify when a specific criterion is suitable. From a practical standpoint, we encourage organizations to recognize that managing fairness in machine learning systems is complex, and that adopting a blind or one-size-fits-all mentality toward algorithmic criteria will surely damage people’s attitudes and trust in automated technology. Instead, firms should carefully consider the subtle yet significant differences between these technical solutions. (shrink)

This paper examines the concepts of desert and luck, familiar in political theory but neglected by sociologists. I argue that the idea of desert is composed of both personal performance and the degree of responsibility a person has over that performance. Distribution ought to be in accordance with the indebtedness created by the person's performance. This can be compromised by luck; that is, personal desert is undermined where lack of performance scuttles the applicability of the contributory model. This paper examines (...) recent work, focusing on establishing desert criteria for each person's ends and life‐plans, and a formula for distribution according to personal welfare. (shrink)

A central strand in philosophical debate over the just distribution of resources attempts to juggle three competing imperatives: helping those who are worst off, helping those who will benefit the most, and then – beyond this – determining when to aggregate such ‘worst off’ and ‘benefit’ claims, and when instead to treat no such claim as greater than that which any individual by herself can exert. Yet as various philosophers have observed, ‘we have no satisfactory theoretical characterization’ as to how (...) to weigh each of the three imperatives against one another, we find it ‘difficult to state... precise or comprehensive conclusions’, and we do not yet have a ‘metric for integrating the three measures’. In what follows, I offer an approach to weighing the three criteria against one another that yields resolutions – in Hard Cases of the ‘saving one infant's life versus replacing ten elderly people's hips’ sort – that are cardinally definitive, intuitively satisfactory and theoretically justified.

COVID‐19 caused an imbalance between medical resources and the number of patients in Türkiye like in many countries. There was not pandemic‐triage system, and this situation led to decision making based on experience, intuition, and judgment of allocation of scarce resources. The research explains the guiding criteria that healthcare professionals used to prioritize the distribution of scarce medical resources during the COVID‐19 pandemic. The criteria preferred by 928 healthcare professionals were evaluated when preventive measures for COVID‐19 were reduced (...) and so the number of cases increased rapidly. The results indicate that Turkish healthcare professionals largely support the utilitarian approach, which focuses on medical benefit in pandemic. The main problem was that some criteria not approved in COVID‐19 triage guidelines were considered important by healthcare professionals. These criteria, which cause discrimination by preventing the provision of fair and equal medical care to patients, are a prominent issue in the study. (shrink)

A new concept of cognition also implies a novel approach to the study of metaphor. This insight is the starting point of this article presenting two innovations to comprehending and analyzing metaphor, one theoretical and one in terms of methodology. On a theoretical level we argue for a new orientation to metaphor and metaphoricity based on enactive cognition and distributed language and cognition. In recent years enactive and distributed cognition have been developing a new concept of cognition as an inter-bodily (...) and ecologically afforded achievement, and in light of this theoretical development we propose an approach to metaphor as a multi-body, multi-party, and multi-timescale phenomenon. On a methodological level we demonstrate a new way of analyzing metaphoricity in multimodal social interaction based on in-depth video analyses of two real life examples in which we introduce metaphorical identification criteria focusing on doubleness in meaning, affordances for co-action, co-ordination, and co-exper..

The aim of this study was to assess the opinions and role of intensive care unit (ICU) nurses regarding the distribution of ICU beds. We conducted this research among 30% of the attendees at two ICU congresses in Turkey. A self-administered questionnaire was used, which included 13 cases and allocation criteria. Of the total (136 nurses), 53.7% participated in admission/discharge decisions. The most important criterion was quality of life as viewed by the physician; the least important was the patient’s (...) social status. According to the findings, the nurses thought that medical benefit and avoiding discrimination were important. On the other hand their ignorance of patients’ autonomous preferences arouses suspicions about these nurses’ role in advocating for patients’ rights. For this reason, nurses’ role in allocation decisions should be clearly described and should also be the basis on which intensive care nurses’ duties in allocation decisions should be determined.

This paper deals with stochastically globally exponential stability for stochastic impulsive differential systems with discrete delays and infinite distributed delays. By using vector Lyapunov function and average dwell-time condition, we investigate the unstable impulsive dynamics and stable impulsive dynamics of the suggested system, and some novel stability criteria are obtained for SIDSs with DDs and IDDs. Moreover, our results allow the discrete delay term to be coupled with the nondelay term, and the infinite distributed delay term to be coupled (...) with the nondelay term. Finally, two examples are given to verify the effectiveness of our theories. (shrink)

This study constitutes an ethical analysis through the lens of distributive justice in the case of the Troubled Asset Relief Program (TARP), which was enacted in the midst of the Great Recession of 2007–2009. It begins by engaging with the visions of justice constructed by John Rawls and Robert Nozick, using their insights to locate the injustices of TARP according to their moral imaginations. However, this study argues that Rawls’ and Nozick’s theories of justice primarily envision the nature of (...) law as being restrictive of vice, not as instructors of virtue. Thus, it resources the legal philosophy of St. Thomas Aquinas to demonstrate how the positive pedagogy of law can enable a more just construction of economic rescue legislation, one that not only prevents future repetitions of economic vices and injustice, but is also formative for a society that prizes economic justice and virtues. In doing so, the study proposes two criteria for a more just consideration of economic rescue legislation that embraces law’s positive pedagogy. (shrink)

Ethical issues relating to the use of the injectable contraceptive in developed and developing countries alike involve public policy decisions concerning both criteria for testing a new drug and individual choices about using a specific form of contraception approved for national distribution. Drug testing consists of an important but still evolving set of procedures. Depo-Provera is not qualitatively different from any other drug and some unpredictable risks are inevitable, even after extensive animal experiments and clinical trials. In assessing the (...) risks and benefits of Depo-Provera use, epidemiological data from large-scale human use is now beginning to become more important than data from animal experiments and clinical trials. The consumer's best interest is central to any ethically responsible system of drug distribution. Systems of informed choice are needed, even in societies where illiteracy remains common and medical services are weak. In the case of a contraceptive, the risks of non-use leading to unintended pregnancy, which can result in high mortality, are relevant as well as the side-effects of the method. An attempt, therefore, is made here to categorise those issues which are universal and those which are country-specific. (shrink)

Our aim is to draw a set of distinctions among types of goods which has significant implications for theories of distributive justice. We begin by providing a general account of two sets of properties--fungibility and nonfungibility, divisibility and indivisibility--and argue that goods can be distinguished according to these criteria. Further, we contend that these distinctions entail complications for structural principles of distributive justice (i.e., principles such as maximin that distribute payoffs to positions). As an example we consider (...) James Fishkin’s discussion of structural principles, arguing that Fishkin’s view that (i) value, structure, and assignment are independent holds only to the degree that the goods considered are fungible and divisible, (ii) structural principles face difficulties beyond those which Fishkin identifies and addresses with his principle of nontyranny, since structural principles cannot accommodate highly non¬fungible, indivisible goods, and (iii) these difficulties can be managed through the application of a value-sensitivity proviso. We then show that two important goods, medical care and advanced education, are highly nonfungible and indivisible and thus support the distinctions drawn earlier. Finally, we specify the nature of complementary contributions as well as coordination problems between structural principles and the value-sensitivity proviso in their application to distributive justice issues. -/- .

I suggest that the diagnosis that an individual self-diagnoses with can be influenced by levels of public awareness. Accurate diagnosis requires consideration of multiple diagnoses. Sometimes, different diagnoses can overlap with one another and can only be differentiated in subtle and nuanced ways, but particular diagnoses vary considerably in levels of public awareness. As such, an individual may meet the diagnostic criteria for one diagnosis but self-diagnoses with a different diagnosis because it is better known. I then outline a (...) potential negative consequence of this. Psychiatric diagnoses can grant access to what I call social resources, namely, political advocacy, campaigning for support, participating in scientific research, building diagnostic cultures, and opportunity for social interactions with people who have the same diagnosis. The strength of the social resources for a particular diagnosis can be made stronger when more people have that diagnosis. As such, inaccurate self-diagnosis can result in the social resources for one diagnosis being strengthened whilst not being strengthened in relation to another diagnosis in comparison to accurate diagnosis. This shows how inaccurate self-diagnosis can alter the distribution of social resources. We need to consider whether this is unfair to people who are diagnosed with less well-known conditions.

A new three-parameter extension of the generalized-exponential distribution, which has various hazard rates that can be increasing, decreasing, bathtub, or inverted tub, known as the Marshall-Olkin generalized-exponential distribution has been considered. So, this article addresses the problem of estimating the unknown parameters and survival characteristics of the three-parameter MOGE lifetime distribution when the sample is obtained from progressive type-II censoring via maximum likelihood and Bayesian approaches. Making use of the s-normality of classical estimators, two types of approximate confidence intervals are (...) constructed via the observed Fisher information matrix. Using gamma conjugate priors, the Bayes estimators against the squared-error and linear-exponential loss functions are derived. As expected, the Bayes estimates are not explicitly expressed, thus the Markov chain Monte Carlo techniques are implemented to approximate the Bayes point estimates and to construct the associated highest posterior density credible intervals. The performance of proposed estimators is evaluated via some numerical comparisons and some specific recommendations are also made. We further discuss the issue of determining the optimum progressive censoring plan among different competing censoring plans using three optimality criteria. Finally, two real-life datasets are analyzed to demonstrate how the proposed methods can be used in real-life scenarios. (shrink)

Little is known about how bow mechanical characteristics objectively and quantitatively influence violinists' preferences and performance. Hypothesizing that the bow shape and mass distribution modifications would alter both violinists' appreciations of a bow and objective assessments of their performance, we recruited 10 professional violinists to play their own violin using 18 versions of a single bow, modified by combining three cambers and six mass distributions, in random order. A musical phrase, composed for this study, was played legato and spiccato at (...) three octaves and two tempi. Each violinist scored all 18 bows. Then, experts assessed the recorded performances according to criteria inspired by basic musical analysis. Finally, 12 audio-descriptors were calculated on the same note from each trial, to objectivise potential acoustic differences. Statistical analysis reveals that bow camber impacted the violinists' appreciations, and that heavier bow tips gave lower scores for spiccato playing. The expert evaluations reveal that playing with a lighter bow, or with a bow whose camber's maximum curvature is close to the frog, had a positive impact on some violinists' performance. The “camber-participant” interaction had significant effects on the violinists' appreciations, on the expert's evaluation and on almost all the audio-descriptors. While trends were identified, multiple camber-participant interactions suggest that bow makers should provide a variety of cambers to satisfy different violinists. (shrink)
