Modal accounts of normality in non-monotonic reasoning traditionally have an underlying semantics based on a notion of preference amongst worlds. In this paper, we motivate and investigate an alternative semantics, based on ordered accessibility relations in Kripke frames. The underlying intuition is that some world tuples may be seen as more normal, while others may be seen as more exceptional. We show that this delivers an elegant and intuitive semantic construction, which gives a new perspective on defeasible necessity. Technically, the (...) revisited logic does not change the expressive power of our previously defined preferential modalities. This conclusion follows from an analysis of both semantic constructions via a generalisation of bisimulations to the preferential case. Reasoners based on the previous semantics therefore also suffice for reasoning over the new semantics. We complete the picture by investigating different notions of defeasible conditionals in modal logic that can also be captured within our framework. (shrink)

Medical tourism is the practice of traveling across international borders with the intention of accessing medical care, paid for out-of-pocket. This practice has implications for preferential access to medical care for Canadians both through inbound and outbound medical tourism. In this paper, we identify four patterns of medical tourism with implications for preferential access to care by Canadians: Inbound medical tourism to Canada’s public hospitals; Inbound medical tourism to a First Nations reserve; Canadian patients opting to (...) go abroad for medical tourism; and Canadian patients traveling abroad with a Canadian surgeon. These patterns of medical tourism affect preferential access to health care by Canadians by circumventing domestic regulation of care, creating jurisdictional tensions over the provision of health care, and undermining solidarity with the Canadian health system.

The present study provides evidence that the activation strength produced by emotional stimuli must pass a threshold level in order to be consciously perceived, contrary to the assumption of continuous quality of representation. An analysis of receiver operating characteristics for attentional blink performance was used to distinguish between two models of emotion perception by inspecting two different ROC’s shapes. Across all conditions, the results showed that performance in the attentional blink task was better described by the two-limbs ROC predicted by (...) the Krantz threshold model than by the curvilinear ROC implied by the signal-detection theory.

Systems of universal health coverage may aspire to provide care based on need and not ability to pay; the complexities of this aspiration call for normative analysis. This special issue arises in the wake of a judicial inquiry into preferential access in the Canadian province of Alberta, the Vertes Commission. I describe this inquiry and set out a taxonomy of forms of differential and preferential access. Papers in this special issue focus on the conceptual specification of (...) health system boundaries and on the normative questions raised by complex models of funding and delivery of care, where patients, providers, and services cross system boundaries.

The debate concerning whether to legalize and regulate the global market in human organs is hindered by a lack of adequate bioethical language. The author argues that the preferential option for the poor, a theological category, can provide the grounding for an inductive moral epistemology adequate for reforming the use of culturally Western bioethical language. He proposes that the traditional, Western concept of bioethical coercion ought to be modified and expanded because the conditions of the market system, as viewed (...) from the perspective of organ vendors systemically deprived of access to sufficient resources, are sufficiently exploitative as to diminish the possibility of these vendors giving informed consent. Moreover, empirical studies conducted by professionals in medicine, sociology, psychiatry, economics, and medical anthropology continue to contribute support to the growing interdisciplinary consensus that functionally coercive structural factors exert the most significant influence upon a vendor's decision to sell an organ within any market, regardless of legality or degree of regulation. Therefore any proposal to legalize and regulate the organ market remains patently unethical because doing so would likely function to constrain further the agency of poor potential vendors. (shrink)

We introduce and explore the notion of duality for entailment relations induced by preference orderings on states. We discuss the relationship between these preferential entailment relations from the perspectives of Boolean algebra, inference rules, and modal axiomatisation. Interpreting the preference relations as accessibility relations establishes modular Gödel-Löb logic as a suitable modal framework for rational preferential reasoning.

In June 2020, Gilead agreed to provide the USA with 500 000 doses of remdesivir—an antiviral drug which at that time was percieved to show promise in reducing the recovery time for patients with COVID-19. This quantity represented Gilead’s then full production capacity for July and 90% of its capacity for August and September. Similar deals are evident around access to proposed vaccines for COVID-19, and such deals are only likely to increase. These attempts to secure preferential (...) class='Hi'>access to medicines and vaccines, so-called vaccine/treatment nationalism, jeopardise supplies of life-saving treatments and vaccines available elsewhere, and jeopardise global equitable distribution of such vaccines/treatments more generally. Much of the focus to date has been on States’ role in negotiating such deals. However, such developments also demonstrate the power patent holders have in controlling access to life-saving healthcare, determining who obtains access first and at what price. This article argues that the extent of control currently given to patent holders for COVID-19 must be questioned. This article demonstrates that patents have significant implications for healthcare acting as private governance tools over patented inventions. It is only by greater probing of patent holders’ role in delivering access to medicines, diagnostics and vaccines for COVID-19 that equitable global equitable access can be achieved. (shrink)

The aim of this article is to consider whether, when, and why it is morally right to treat members of socially disadvantaged racial or ethnic groups favorably when allocating scarce medical resources. Since the COVID 2019 pandemic has had different impacts on racial and ethnic groups, some U.S. states have given racial and ethnic minorities preferential access to COVID-19 vaccines, leading to controversy over the moral and legal permissibility of doing so. I examine three arguments for affirmative action—the (...) compensation, equality-of-opportunity, and antidiscrimination arguments—and argue that both the equality-of-opportunity and antidiscrimination arguments have the potential to provide well-founded justification for race-based affirmative action for the allocation of scarce medical resources. I also consider further moral requirements that instances of affirmative action based on both or either of the two arguments should comply with for them to be justified. (shrink)

Background In the UK, the solidaristic character of the NHS makes it one of the most trusted public institutions. In recent years, the introduction of data-driven technologies in healthcare has opened up the space for collaborations with private digital companies seeking access to patient data. However, these collaborations appear to challenge the public’s trust in the. Main text In this paper we explore how the opening of the healthcare sector to private digital companies challenges the existing social contract and (...) the NHS’s solidaristic character, and impacts on public trust. We start by critically discussing different examples of partnerships between the NHS and private companies that collect and use data. We then analyse the relationship between trust and solidarity, and investigate how this relationship changes in the context of digital companies entering the healthcare system. Finally, we show ways for the NHS to maintain public trust by putting in place a solidarity grounded partnership model with companies seeking to access patient data. Such a model would need to serve collective interests through, for example, securing preferential access to goods and services, providing health benefits, and monitoring data access. Conclusion A solidarity grounded partnership model will help establish a social contract or licence that responds to the public’s expectations and to principles of a solidaristic healthcare system.

OBJECTIVES: To study and report the attitudes and practices of physicians in a former Soviet republic regarding issues pertaining to patients' rights, physician negligence and the acceptance of gratuities from patients. DESIGN: Survey questionnaire administered to physicians in 1991 at the time of the Soviet breakup. SETTING: Estonia, formerly a Soviet republic, now an independent state. SURVEY SAMPLE: A stratified, random sample of 1,000 physicians, representing approximately 20 per cent of practicing physicians under the age of 65. RESULTS: Most physicians (...) shared information with patients about treatment risks and alternatives, with the exception of cancer patients: only a third of physicians tell the patient when cancer is suspected. Current practice at the time of the survey left patients few options when physician negligence occurred; most physicians feel that under a reformed system physician negligence should be handled within the local facility rather than by the government. It was common practice for physicians to receive gifts, tips, or preferential access to scarce consumer goods from their patients. Responses varied somewhat by facility and physician nationality. CONCLUSION: The ethics of Soviet medical practice were different in a number of ways from generally accepted norms in Western countries. Physicians' attitudes about the need for ethical reform suggest that there will be movement in Estonia towards a system of medical ethics that more closely approximates those in the West. (shrink)

In this commentary on an article by Jennifer Blumenthal-Barby (AJOB 16:5-15, 2016), we discuss how external influences on decisions affect personal autonomy. Specifically, we introduce the idea of “pre-authorization” as an evaluative stance by which an individual gives a certain agent preferential access to influencing her decision-making processes. Influences arising from pre-authorized agents may then be seen as promoting, rather than infringing upon, autonomy. While the idea that an external influence can be autonomy-promoting may be inconsistent with individualistic (...) conceptions of autonomy, it aligns well with more relational conceptions that recognize the social milieu in which decisions are made. We suggest that pre-authorization provides a framework for thinking about how relational accounts of autonomy might work mechanistically. (shrink)

We examine whether the behavior of institutional investors representatives on boards leads to observable differences in corporate finance. We find that directors representing pressure-sensitive investors prefer lower financial leverage whereas pressure-resistant directors show no particular preference. When analyzed separately, directors appointed by banks and insurance firms have different attitudes. Bank representatives on boards increase both the financial leverage and the banking debt. This result suggests that some types of institutional directors provide financial resources to the firms on whose board they (...) sit, supporting the view that boards manage the uncertainty associated with strategic decision making and provide firms with preferential access to resources and financial expertise. This research has interesting academic and policy implications for the debate over the proper degree of institutional involvement in corporate governance. Different institutional investors have different agendas and incentives for corporate governance, and, therefore, both researchers and policy makers should no longer consider institutional investors as a whole. In addition, our paper calls for new research on the causes and implications of institutional investor involvement in the corporate governance of nonfinancial firms. This new research could require new insights on the dynamics within the boards and on the interplay among the knowledge, incentives and attitudes of quite different directors. (shrink)

We introduce -ranked preferential structures and combine them with an accessibility relation. -ranked preferential structures are intermediate between simple preferential structures and ranked structures. The additional accessibility relation allows us to consider only parts of the overall -ranked structure. This framework allows us to formalize contrary to duty obligations, and other pictures where we have a hierarchy of situations, and maybe not all are accessible to all possible worlds. Representation results are proved.

The specific issue addressed in this paper is urban encroachment on agricultural lands, and the problems it poses for both analysis and the conservation of the land resource. The purpose of our discussion is two-fold: (1) to identify where and why traditional analytical and regulatory approaches fail to resolve land use conflicts, and (2) to explore ways and means of resolving some of the dilemmas which society faces in making land use decisions. This paper's contribution is in the spirit of (...) Getting Incentives Right for the inter-temporal transfer of wealth, as represented in trade-offs between environmental and resource endowments and human and physical capital. Efforts are placed on identifying what the appropriate price, levy, taxes, and grant ratios ought to be in order to encourage individuals in the marketplace to act in society's interest. We have also explored ways of efficiently transmitting those incentives through the market mechanism, without unduly relying on bureaucratic methods or suasion. Emphasis is placed on mechanisms that have little scope for preferential access and are subject to public scrutiny; emphasis on such self-disciplining approaches should result in less effort expended on (unproductive) lobbying activities and bureaucratic administration.

Fair trade banana farming in the Windward Islands of the Caribbean has emerged since the late 1990s in response to a crisis. Rulings by the World Trade Organization ended a longstanding trade dispute between the US and the EU by eliminating a system of preferential access of Windward Island bananas to the UK market. What followed was a period of rapid decline in banana exports from these small islands and a widespread abandonment of banana cultivation. Those banana farmers (...) who remain are now primarily fair trade producers. Fair trade banana production in the Windward Islands can thus be conceived as a survival strategy that farmers have developed in response to a particular instance of neoliberal globalization. The paper considers this response especially in the context of recent fieldwork on the island of St. Vincent. In light of contributions by several scholars who have drawn upon the work of Polanyi to understand both fair trade and resistance to neoliberalism, fair trade banana production in the Windward Islands appears significant not only as a local survival strategy, but also as part of a larger countermovement that resists neoliberal globalization.

Logics are like shadows on a wall; to understand why they dance as they do, and how they can be made to move differently, one needs to look at the mathematical structures from which they can be projected. That is a methodology that has long proven its value for classical and other forms of deductive inference; this book manifests its pertinence to logics of uncertain qualitative reasoning. It draws together and refines work from the literature on preferential and other (...) quite different semantics for such reasoning and then, in its central chapter, integrates the leading ideas from them into a single multi-dimensional semantics. It enters new territory with investigations of interpolation and qualitative independence in non-monotonic contexts as well as connections between non-monotonic logic and neuroscience, specifically with Edelman's theory of organization of the brain. Finally, it proposes novel applications such as equational modellings for contrary-to-duty normative reasoning and mathematical analyses of some kinds of casuistic reasoning in the Talmudic tradition.

This multiplex semantics incorporates multiple relations of deontic accessibility or multiple preference rankings on alternative worlds to represent distinct normative standards. This provides a convenient framework for deontic logic that allows conflicts of obligation, due either to conflicts between normative standards or to incoherence within a single standard. With the multiplex structures, two general senses of "ought" may be distinguished, an indefinite sense under which something is obligatory when it is enjoined by some normative standard and a core sense for (...) when something is enjoined by all normative standards. Multiple normative standards may themselves be given a preferential order; this leads to a concept of ranked obligation. This paper presents the foundations of this multiplex semantics and the propositional deontic logics they define. (shrink)

This is a groundbreaking application of contemporary philosophy to human rights law that proposes significant innovations for the progressive development of human rights. Drawing on the works of prominent 'philosophers of the Other' including Emmanuel Levinas, Gayatri Chakravorti Spivak, Judith Butler and, most centrally, the Argentine philosopher of liberation Enrique Dussel, this book develops an ethics based on concrete face-to-face relationships with the Marginalized Other. It proposes that this should inspire a human rights law that is grounded in transcendental justice (...) and framed from the perspective of marginalized groups. This would continuously deconstruct the original violence found in all human rights treaties and tribunals and promote preferential treatment for the marginalized. It would be especially attentive to such issues as access to justice, voice, representation, agency and responsibility. This differs markedly from more conventional theories that prioritize the autonomy of the ego, state sovereignty, democracy and/or equality. (shrink)

In response to commentators, we argue that whether waiving patent rights will meaningfully improve access to COVID-19 vaccines for low income and middle-income countries (LMICs), particularly in the short term, is an empirical matter. We also reject preferentially allocating vaccines to countries that hosted trials because doing so unethically favours those with research infrastructure, rather than those facing the worst burdens from COVID-19.

The interactions between genetic and environmental risk factors contribute to the aetiology of complex human diseases. Genome‐wide association studies (GWAS) have revealed that most of the genetic variants associated with complex diseases are located in the non‐coding part of the genome, preferentially within enhancers. Enhancers are distal cis‐regulatory elements composed of clusters of transcription factors binding sites that positively regulate the expression of their target genes. The generation of genome‐wide maps for histone marks (e.g., H3K27ac), chromatin accessibility and transcription factor (...) and coactivator (e.g., p300) binding profiles have enabled the identification of enhancers across many human cell types and tissues. Nonetheless, the functional and pathological consequences of the majority of disease‐associated genetic variants located within enhancers seem to be rather minor under normal conditions, thus questioning their medical relevance. Here we propose that, due to the prevalence of enhancer redundancy, the pathological effects of many disease‐associated non‐coding genetic variants might be preferentially (or even only) manifested under environmental stress.

In lieu of an abstract, here is a brief excerpt of the content:Christian-Buddhist Dialogue on Loving the EnemyWioleta PolinskaWe are taught to think that we need a foreign enemy. Governments work hard to get us to be afraid and to hate so we will rally behind them. If we do not have an enemy, they will invent one in order to mobilize us. Yet they are also victims.1—Thich Nhat HanhWe are called to speak for the weak, for the voiceless, for (...) the victims of our nation, and for those it calls enemy, for no document from human hands can make these humans any less our brothers.2—Martin Luther King Jr.Literally speaking, Ahimsa means "non-killing."... To one who follows this doctrine there is no room for an enemy.3—M. K. GandhiIn his autobiography, Martin Luther King Jr. comments that he initially considered Jesus's commands such as "turn the other cheek" or "love your enemies" as limited to individual relationships. Only after reading Gandhi in the late 1940s did he conclude that the love ethic had a much broader scope. Love became to him an effective principle applied to racial groups and nations in conflict and was "a potent instrument for social and collective transformation."4 Some years later, King was influenced by another Asian religious thinker, the Vietnamese Zen Buddhist monk Thich Nhat Hanh. Under Nhat Hanh's influence, King repudiated the war in Vietnam by addressing the similarity between the Vietnamese Buddhist peace movement and the American civil rights movement.5Nhat Hanh and King were both inspired by Gandhi's peaceful approach to social conflicts. All three are exemplary models of love and nonviolence in their respective Buddhist, Christian, and Hindu traditions. Whether ahimsa (or harmlessness) in Hinduism, compassion for all beings in Buddhism, or "love of enemy" [End Page 89] in Christianity, unconditional love signifies the principal concern of these spiritual thinkers. All three men display an uncompromising commitment to the cause of the oppressed and downtrodden, but, at the same time, they refuse to vilify the opponents. In fact, all three speak of the "love of enemy" as the only sure way to ensure peaceful solution to any social crisis. Recent military conflicts prompted by the tragedy of September 11 offer a challenge for rethinking the most effective ways of dealing with international terrorism and other forms of social struggles. In what follows, I will suggest that, like Martin Luther King Jr., Christians can benefit from engaging in a dialogue with Eastern thought. Specifically, by focusing on the writings of Thich Nhat Hanh, I will engage Christian liberation theologies to offer a possible corrective to a theological reflection on social conflict. In conversation with sociological reflection on war, political theorists, and artists, this article will present a fresh reexamination of a nondualistic, nonviolent approach to military and social conflicts.Social exploitation, injustice, and oppression are focal points of many contemporary Christian theologies that are indebted to Latin American liberation theology. Recognizing the suffering of the poor and the failure of the historical Christian church to address the systemic injustice against them, liberation theologians affirm solidarity with the poor. Because of oppression and poverty, the poor have privileged access to the meaning of the Gospel (hermeneutic privilege) and the church needs to commit to a "preferential option for the poor." That is, those "who are privileged must identify with the poor and the oppressed not only because they need us but also because, from their experience of poverty and oppression, they are in a better position to understand the Gospel."6 Learning from the poor implies interpreting Christian faith out of the suffering of the poor; it implies seeing God as the God of the poor and the oppressed. The poor are seen as "the favorites of God"7 because they receive continuous divine attention to their struggle. The liberation of the Israelites from Egypt, Jesus's solidarity with the poor by becoming one of them, as well as his preaching the good news to them, are all examples of God's love for the poor. God's solidarity with the victims of social oppression reaches its zenith in the resurrection of Jesus when God is "doing Justice... (shrink)

Photo by Jonathan Ford on Unsplash ABSTRACT Since 2008, an average of twenty million people per year have been displaced by weather events. Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. This paper analyzes the idea of expanding a duty to rescue to climate migration. We address who should have (...) the duty and to whom the duty should extend. The paper discusses ways to define and apply the duty to rescue as well as its limitations, arguing that it may take the form of an ethical duty to prepare. INTRODUCTION Climate migration creates a special setting for a duty to rescue. A duty to rescue is a moral rather than legal duty and imposes on a bystander to take an active role in preventing serious harm to someone else. Examples of circumstances range from person-to-person intimate rescue to saving those in poverty, even in distant parts of the world.[1] Since 2008, an average of twenty million people per year have been displaced by weather events.[2] Circumstances like being thrust from homes under the threat of fire, mudslide, and flooding vary greatly from long-term changes like land becoming too arid for crops or temperatures increasing annually gradually pushing up the number of heat-related deaths, with the area slowly becoming uninhabitable. Imminence in fleeing affects resettling and need for rescue with important implications for how the duty to rescue might apply. This paper reevaluates the ethical framing of the duty to rescue and, while it is arguably a stretch, applies it to climate migration. Climate migration has become common and is expected to increase due to rises in sea level, increases in weather events that make areas uninhabitable, and changes to land that preclude farming or other necessary land uses. We argue that a duty to rescue may help highlight who has moral obligations to whom. Because the problem is so large in scope, we suggest a change in the ethical limits to humans' duty to rescue other humans who are in distress. We imagine an expansion or extension of the duty to rescue to meet some of the basic needs created by climate migration. Yet how it should expand, and how much depend on ethical framing and practical limitations. l. Expanding the Geographical Boundaries Two commonly recognized emergencies, Hurricane Katrina in the case of weather events and the current COVID-19 pandemic, provide a historical and current backdrop to evaluate ethical obligations as more disasters displace people. A significant reassessment of the ethical scope of an obligation to rescue in the case of weather events will be limited by the ability to render aid to those in distress in the case of a planet-wide weather catastrophe. The problems may overwhelm the ability to rescue or the reasonableness of attempting rescue. The extent of the moral obligation borne by humans to other humans in the case of a weather event has been largely defined by its locality and limited geographic influence. Whether we are imagining the scope of ethical obligation in the case of hurricane, flood, tornado, drought, or wildfire events, the perceived ethical obligation is significantly defined by the limited impact of these weather events on people outside the zone of the weather event's direct impact, yet close to that zone. A hurricane affecting New Orleans will not have immediate impact on the residents of California or even those on the northeast coast of the United States until a later time. Wildfires in the Pacific Northwest do not impair the ability of those in the rest of the country to come forward with assistance. But as climate migration crosses international borders, and climate events occur simultaneously in many regions, a more expansive duty to rescue may provide the ethical impulse to help those who live afar or migrate long distances. In this respect, the need for help in the event of widespread climate migration due to global warming is more like a pandemic than a weather event. Its broad impact area diminishes the capability of nearly the entire balance of the human population to help due to those populations' awareness that they will, in short order, have the same need for the same resources, from the same cause. Those living near current flood zones may find their historically safe havens are also a flood zone. Those previously best positioned to rescue may find themselves also needing to relocate. Thus, we may observe the need for new rescuers. ll. The Rule of Rescue The Rule of Rescue as defined by Al Jonsen describes the moral impetus or knee jerk reaction to save identifiable people facing death.[3] A duty to rescue has since been expanded beyond imminent death and beyond the near and identifiable. But there are limitations. For example, by most accounts, the ethical duty tends not to require extreme bodily risk or financial depletion. In comparing Good Samaritans to humanitarians, Scott M. James argues the duty to rescue arises from unique dependence, but the ethical obligation to help strangers through humanitarian aid is of a different nature.[4] The wrongness of failing to help is arguably more egregious when one is in a unique position to help. Like in the tragedy of the commons, where there is no unique positioning, when the global community is called upon to help, each individual in it may feel less obliged to do so. Climate migration falls in between—it requires helping strangers, yet it may move forward without anyone seeing themselves as uniquely positioned to help until those strangers become part of communities, at which time, there may be more moral justification to help a community member in need. Generally, arguments about Good Samaritans hinge on extraordinary acts, praiseworthy because they are acts of compassion, not obligation. Now all US states have Good Samaritan laws[5] which protect helpers from liability for help gone wrong or for a failure to succeed once engaged in an act of rescue. Extraordinary help as a moral good is thus somewhat encouraged through legal protection, but not imposed. Conversely, jobs like firefighting, search and rescue, and emergency medical care tend to oblige employees to take on risks that would be extraordinary if undertaken by the average bystander, yet they are rendered ordinary rescue as part of the job. Three states, Minnesota, Rhode Island, and Vermont have a broad duty to rescue, adding legal considerations to an otherwise moral conundrum. The laws do not require bystanders to take on risk for the sake of rescuing strangers.[6] The moral duty will require looking beyond law, but it is unclear how the moral duty to rescue should be distributed in the case of climate migration. A bare minimum would prevent taking advantage of newcomers, paying sub-minimum wage, and discriminating against them. Yet such a minimum is hardly rescue. lll. An Ethical Rather than Legal Duty The difficulty in defining the duty to rescue as a legal obligation is that it is difficult to determine the extent of risk a rescuer ought to be required to take. The nature of this ethical duty is also arguably tied to the experiences of both the rescuer and the rescued. There are subjective aspects like what someone perceives as a danger that make it difficult to write enforceable laws requiring rescue. It is one thing to expect a rescuer to step into several inches of relatively warm water to lift a person lying face down in a pond and enable them to breathe. It is something altogether different to expect that rescuer to dive into frigid water and attempt to extricate someone trapped in a submerged automobile. As the legal philosopher H.L.A. Hart observed, it is always easier to define application of the core intention of any rule, whether law or ethical norm. It is more difficult to create legal certainty about how the law applies to what he described as “penumbra circumstances”. In the case of a hurricane, it is easier to define what surplus resources are available in areas geographically remote from the impact of the storm and demand, as a moral obligation, that those nearby but outside the area provide assistance. It is more difficult to obligate people, organizations, or governments to supply a quantity of medication or some number of ventilators to an adjacent community when they expect to imminently need them for their own community. In the early stages of climate migration, the ethics of extreme weather event assistance, a common application of the duty to rescue, will be useful and appropriate. The rising sea levels first experienced by island nations in the South Pacific[7] will not render those living in other coastal communities, those with greater available “high ground”, unable to supply resources to those in need. But when sea level rise and climate change affect more communities simultaneously, albeit in varying degree, the task of defining what response is ethically obligatory becomes increasingly complicated. Pinpointing the obligations of those communities which are resource rich to those communities which are resource deprived, and of those partly affected to those more severely affected may become necessary. The limitations of the traditional duty to rescue could expand to meet the needs. lV. Contribution to the Problem Many argue that the duty to rescue may depend on any appropriate claim of those needing rescue. One issue is whether preferential claims among those who can identify the source of the harm should call for a greater duty or whether everyone in need should be approached as like candidates for rescue, shaping the duty as equal across those on the receiving end. As climate change does have human-made causes, there are strong arguments to impose a greater ethical duty on any entity that caused the climate-related problems leading to the mass exodus. While the global north is often implicated in pollution that causes migration, industries like energy, transportation, and agriculture are tied to climate change and associated with significant greenhouse gas emissions.[8] Practices like directing agriculture to less sustainable single crop growth generally made land less farmable. Yet it is difficult to place blame and identify specific causal relationships as most migration is due to many factors. A movement toward greater accountability can be reframed as a greater duty to rescue, a duty to engage in the extraordinary. The fossil fuel industry, for example, should have a larger obligation than the average person. Similarly, some may argue anyone unjustly enriching themselves while contributing to climate change or people who over-consume have an elevated duty to rescue.[9] Climate change lawsuits demonstrate an eagerness to hold governments and corporations accountable, despite difficulty proving causation. V. The Most Vulnerable One ethical dimension of climate migration that remains unexplored is how a duty to rescue applies to vulnerable populations who stand to be left behind or unable to migrate without assistance. Researchers from the Global North working across the Global South are increasingly observing the phenomenon of ethics dumping, where the research ethics of some countries are imposed on research subjects in other countries.[10] In that vein, rescuers should be careful not to impose unwelcome cultural standards or exploit people who are in the process of migrating. There is a gap in discussions reflecting voices that have been left out. The duty to rescue is incomplete without an attempt to understand the ethical experiences of those being rescued. The actual people affected by climate migration who are the least likely to have the means to migrate, or to do so without extreme hardship, should have a voice informing the global community including those in a position to carry out rescue. People who have the means and are young and healthy may easily make decisions to avoid the catastrophic consequences that climate migration brings. However, what about those who are left behind? For example, especially recognizing cultural differences, the homeless community, disabled community, refugees, the elderly community, and women[11] and children may suffer differently and call for more attention. In some parts of the world, human rights are severely constrained. An ethical duty to rescue, with many considerations and variables, may be more justified in the case of those most in need. As climate migration continues and increases significantly, it may be reasonable to ask the local and global community to focus on those least well positioned to migrate successfully. In this context, the use of phenomenology to understand the lived experiences of those migrating, sometimes termed “ethical experiences”, may help flesh out how a duty to rescue takes shape. The discussion of duty and obligation requires an articulation of the ethical experiences (how the local community in need of rescue views the proposed rescue). Then, the obligation to interpret the duty as ‘one shall not’ or ‘one must’ can be focused on the migrants’ needs rather than the rescuers’ feelings of obligation.[12] A revised theory of the duty to rescue taking into account the asymmetrical experiences of communities involved could ensure that the needs of people whose living situations, gender, ethnicity, age, or race impact their ability to even begin the migration process are considered. In this discussion, the rescuing is directed toward communities /collectives of persons migrating, whether at once or across a period of time. Often, the climate migrant may not be in a state to articulate the nature of this event when it happens, given its subjective proximity. Yet, when communities are given the space and opportunity to articulate their shared values, the ethical action of rescue derives its meaningfulness from the community rather than the rescuers. In other words, allowing climate migrants to explain their feelings can add complexity to what some see as a binary receiver-giver (of rescue) dynamic. This is necessary because the concept of vulnerable populations is fraught with problematic assumptions. There have been various definitions and criteria to determine what would constitute vulnerable populations.[13] For example, the United Nations Framework Convention on Climate Change[14] identifies and assesses vulnerable populations. These criteria may be helpful. However, they do not provide the full picture. Rather than identifying categorical criteria of vulnerable populations, engaging with people who are experiencing climate migration and listening to their current experiences and concerns helps determine need. Knowing what people need may prevent the kneejerk reaction to label people who are quite resilient yet have appropriate needs “vulnerable”. Proceeding with caution is important because the duty to rescue has hierarchical underpinnings of "us" and "them." Often when people swoop in to save, there are good and bad consequences of the intervention. We should proceed with caution because often the helper misses the actual needs of those in need. The only way to combat this would be to make sure that people are empowered to inform those agencies that are able to help. In addition to more practical approaches, large scale oral histories could allow those who have migrated already to share their experiences. It would be important to capture the lived experiences of people who are already experiencing the consequences of climate migration or of other migration like that due to political or economic extreme events. These experiences could shape our analysis of whether people in fact wish for rescue. If so, further conversations can determine best actions as well as give important insight into what resources might be necessary to empower people now and in the future. Vl. A Duty to Rescue as a Duty to Prepare If we view Good Samaritans as going above and beyond, then a duty to rescue, something ethically compelled, must bring rescue out of the framework of charity and place it in the context of humanity and obligations. Such a view would also support expanding the geographical reach of the otherwise more proximate duty. The duty may be stronger and take shape in a more workable way if it applies to preparing places expecting to see an influx of people due to climate migration and to helping those most in need. The duty may arise out of expectations of what type of community the place welcoming those migrating due to climate should be—does it want to offer good housing, schooling, and medical care as well as economic opportunity to new people? And if so, at what cost, or with which risks? If the newcomers are viewed as community members rather than strangers, a model of acceptance may lead to better preparation. Some considerations like whether the actions will reasonably help the persons in need of rescue[15] will shape the application of a duty to rescue in the context of climate migration. Similarly, ensuring that people have the chance to articulate their values may help communities support the newcomers. New relationships should not be defined as migrant and rescuer. Voluntariness in participation and not forcing any action deemed rescue would help ensure the human rights of those migrating. In the United States, President Biden issued an executive order addressing impending climate migration steeped in a duty to prepare by making plans for resettlement and to address the impact of climate migration.[16] Vll. At What Risk? As we investigate the ethical obligations to meet even basic needs, we must also ask what level of risk is ethically compelled. There is an extraordinary need to integrate newcomers successfully, but it is difficult to stretch an ethical duty to rescue to require all the prerequisites for successful climate migration. Even defining success would create deep ethical arguments. As observed in almost all migrations, extraordinary charitable acts may be the key to success, while an ethical duty to rescue must try to require the important government and community-based basics and ensuring respect for human rights. That is, the migrating people should be rescued from circumstances that contradict basic human rights. Rather than comparing communities to bystanders, mere places where people will arrive and need to hash out how to find housing, jobs, education, and opportunity, a duty of preparation may be the key to rescue those disenfranchised by migration. There are cultural, personal, physical, psycho-social, and geopolitical issues surrounding how to best help those needing to permanently relocate. Ethics arguments will certainly range from “do nothing”, which may fail people, to “do everything”, which could waste taxpayer money in futile over-preparation while failing to actually help. Communities must avoid planning exclusively for one scenario only to have it not take place. Striking the balance, a duty to rescue as it could apply to climate migration should set goals of societal integration, and providing the basics like education, housing, food, health care, and job opportunity, the precursors to flourishing. Recommending the extraordinary, morally preferred but perhaps not compulsory, when charitable actors are participating, or when wrongdoers are compensating, may be more workable than seeing the duty to rescue as compelling people or local governments to take on significant financial and personal risk for newcomers. While humanitarian ethics supports helping everyone, it is likely that people who resettle in advance of a need to flee will find themselves with more choices and opportunities. Help is warranted for those with more dire needs. Preparing for them may do just that. Vlll. Rescue Prior to Migration and Rescue in the Process of Resettlement The duty to enable the migration in the first-place hints to the inadequacy of a duty to prepare. The traditional duty to rescue perhaps steps in if rescue looks like those geographically just out of harm's way rescuing those in danger. That resembles the traditional moral requirement, or duty to rescue according to the Rule of Rescue. Humanitarian aid typically provided by many institutions makes sense and is in place, although financial support for additional humanitarian aid is always needed. Despite having moved to purportedly more capable communities, migrant communities may be able to develop more egalitarian orders of living. Rather than continually being identified as having been rescued, it is important to make sure people keep or make social ties during and after migration. Immigrants often face social isolation.[17] Small shifts in gestural language also have the potential to welcome people and show they are valued. For instance, some migrants may not like questions like “Where are you from?” and “What brings you here?” as they emphasize differences over fitting in. CONCLUSION The ethical duty to rescue should be expanded to better match those in need of relocation with a welcome environment and the resources needed to achieve success and fully integrate socially and culturally. Expanding a dialogue that includes the voices of people who have recently migrated whether due to violence, poverty, or climate, could properly frame the extent of the duty. If we are to apply the duty of rescue to climate migration, rescuers should avoid labeling people vulnerable, dependent, or needy, although there is reason to focus on those whose needs are the most dire. A soft duty to rescue people during the course of climate migration can come in the form of preparation. People will need help finding housing, education, access to food, and employment. Ultimately, to help them help themselves may be the best goal. While the obligations should be borne differently by people, whether due to a special responsibility, or a special relationship that creates a clearer duty, the global community must prepare for its role in rescuing those displaced by climate events. By helping those displaced at the start of the climate migration process according to a more commonly held notion of the duty to rescue, and by preparing to incorporate newcomers successfully according to an expanded duty to rescue, effectively a duty to prepare, countries that take on climate refugees may find themselves rewarded by the cultural diversity and workplace talents that people bring. A duty to those at a distance is a reasonable expansion of the duty to rescue. But what one ought to do in the global community varies somewhat from the traditional Rule of Rescue. - [1] Singer, P.

Catholic end-of-life ethics does not contain a principle that prohibits the excessive use of medical treatment for declining and dying patients. This article fills this lacuna by exploring and developing the principle of unreasonable means. Unreasonable means are present when the burdens to the patient and community far outpace the benefits to the patient and when the use of such means directly or indirectly limits another patient’s access to ordinary means. Unreasonable means reinforce the redistribution of limited medical resources (...) from the poor to the wealthy and from the global south to the global north. The principle of unreasonable means guides individual patients and medical proxies to preferentially opt for the morally ordinary medical needs of others before the patient’s own extraordinary medical needs. The principle underscores the need for patients and proxies to incorporate justice and the common good into end-of-life decisions. (shrink)

Cognition or higher brain activity is sometimes seen as a phenomenon greater than the sum of its parts. This viewpoint however is largely dependent on the state of the art of experimental techniques that endeavor to characterize morphology and its association to function. Retinal ganglion cells are readily accessible for this work and we discuss recent advances in computational techniques in identifying novel parameters that describe structural attributes possibly associated with specific function. These parameters are based on calculating wavelet gradients (...) from cell images followed by the extraction of meaningful measures including 2nd wavelet moment, entropy of orientation, and curvature. For the three cell types analyzed, the mean 2nd wavelet moment, which relates to the field of influence of the dendritic-tree segments was significantly different. cells had the highest mean 2nd wavelet moment, followed by the and cells (134 ± 22, 93 ± 19 and 63 ± 12, respectively). There was no significant difference between cells for entropy of orientation, indicating no class with a preferential orientation of their dendritic tree. Curvature provided similar results to the 2nd wavelet moment with cells having the highest curvature followed by and the cells (mean ± SD: 161 ± 15; 134 ± 22; 121 ± 15). Our feature space analysis also indicated a difference between these cell types. No difference was found between the and cell types and their physiological counterparts the Y and X cells based on wavelet analysis. Both the X and Y cells can be divided into two subtypes, the ON- and OFF-center cells based on the stratification level of the dendritic tree within the retina. Using 2nd wavelet moment, a difference in their morphological attributes, not reported previously, was noted for these subtypes. The 2nd wavelet moment and curvature are further discussed with respect to explaining regularity of spacing and coverage associated with retinal ganglion cell mosaics. (shrink)

The Americans With Disabilities Act (ADA) promotes social justice by protecting disabled persons from discrimination and prejudice. It seeks equality of opportunity for them and protects their well being by giving them fair access to goods, services and benefits. These rights are circumscribed in the ADA, however, by constraints of cost, efficiency, utility, and certain social mores. The ADA offers little direction about how to set priorities when these values come into conflict, or about whether equality of opportunity favors (...) equivalent or preferential treatment for disadvantaged people. Until these ambiguities and potential value conflicts are resolved, a central moral and social problem remains unresolved: How can we demonstrate commitment to the rights and welfare of those with severe disabilities while placing fair limits upon their claims? Five special concerns are discussed: (1) eligibility and the allocation of health care; (2) the meaning of ‘qualified but disabled’ in employing people with mental disabilities; (3) equal opportunity and problems of envy and malingering; (4) ADA accommodation and public protection through testing and licensure; and (5) ADA protection and problems of backlash. Rather than simply wait to see what courts and administrative agencies decide, we should evaluate the moral conflicts, articulate criteria, and help make some difficult choices on morally defensible grounds.

The substantive center of Christian ethics is Jesus’s ministry of the kingdom or reign of God, and its preferential inclusion of the poor, the outcast, and the sinner. What defines a gospel-based bioethics is a hopeful, practical commitment to improve the health of those who are most vulnerable to illness and early death because they lack basic needs. This commitment is distinctive of Christian bioethics, if not “unique” in the sense that no other bioethical approaches or traditions share it. (...) To succeed in reducing disparities in access to health care requires cooperative social action with members of multiple moral and political communities, meaning that there is no strict boundary between secular and Christian bioethics at the practical, political level, the level of applied Christian social ethics.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Renewing Moral Theology: Christian Ethics as Action, Character, and Grace by Daniel A. WestbergHoward HarrisRenewing Moral Theology: Christian Ethics as Action, Character, and Grace Daniel A. Westberg DOWNERS GROVE, IL: IVP ACADEMIC, 2015. 281 PP. $25.00Renewing Moral Theology by Daniel Westberg has two professed purposes—to be a moral theology text for seminary use and to be a book with wider public appeal. Short chapters, real-life examples, simple reading (...) lists, and unobtrusive footnotes make it accessible to that wider public. Yet the rigor and careful argument will satisfy the need in many introductory classrooms for a moral theology text that is cognizant of Aquinas, Vatican II reforms, and Anglican scholarship.Westberg sees the 1960s as a disruptive time for ethical thought in the Anglican tradition, with the "shifting and seductive winds" of situation ethics gaining sufficient sway to sweep away the prevailing systematic approach to moral theology (9). He seeks to follow an Anglican path of mutual enrichment, blending Evangelical emphases and Catholic moral philosophy. Virtue ethics, with its roots in Aristotle and Aquinas and its more recent renaissance, is at the core of the book. Part 1 deals with moral reasoning and action, while part 2 discusses the seven principal virtues: wisdom in action, justice, fortitude, self-control, faith, hope, and love.The initial focus is on practical reasoning, action, and character, acknowledging that many daily questions have a moral component yet do not require casuistry and law for resolution. Westberg puts forward a four-stage model of practical reason involving intention, deliberation, decision, and execution, sourced from Aquinas (reminiscent of James Rest's Four Component Model). The model is used to show that both intellect and will must be engaged and that the process can be iterative. The importance of the Holy Spirit in the forming of character and in the infusion of the theological virtues is made clear in Westberg's elucidation of the sequence through practical reasoning to action. Christian ethics is different, and Christians need "a new way of explaining Christian discipleship" (18).Part 2 begins with a useful introductory chapter about the development of virtues, with a focus on Christ and a caution against vagueness, against reducing morality to an undefined love that is of little relevance in either deliberation or action. In the discussion of individual virtues, Westberg brings together traditional scholarship, including Aquinas, Augustine, Aristotle, and Barth, with contemporary work from theology, philosophy, and psychology including Hauerwas, O'Donovan, and Veritatis splendor. Westberg questions the idea, grounded in Aristotle, that excellence in a virtue lies in a mean between extremes, wondering [End Page 203] aloud if Aristotle went too far in this (152). The treatment of love includes an examination of the nature of agape in which Westberg sets out to show that this Christian love ought not be seen as self-sacrificing but as mutual and nurturing. The Gospel basis is apparent here as the argument is grounded on "God is love" (1 John 4:16); on examples of Jesus showing preferential love for the disciples and Lazarus, Martha, and Mary; and on "a mutuality of love in the Godhead," before noting parallels to Aristotle's notions of friendship (238–40).Throughout the book difficult questions are not shunned, with diversion avoided by pointing to alternative sources of more detailed analysis; animal ethics, loving one's enemies, and whether non-Christians can be "good" are dealt with in this way, while the implications of biblical teaching on sin receives a longer treatment. Renewing Moral Theology puts Christ at the center of a discussion of how to live well. It is accessible to the Christian who has an interest in moral questions while being sufficiently tightly argued for the introductory classroom at which it is also aimed.Howard HarrisUniversity of South AustraliaCopyright © 2017 Society of Christian Ethics...

Histone octamers (hos) and DNA topoisomerase I contribute, along with other proteins, to the higher order structure of chromatin. Here we report on the similar topological requirements of these two protein model systems for their interaction with DNA. Both histone octamers and topoisomerase I positively and consistently respond to DNA supercoiling and curvature, and to the spatial accessibility of the preferential interaction sites. These findings (1) point to the relevance of the topology‐related DNA conformation in protein interactions and define (...) the particular role of the helically phased rotational information; and (2) help to solve the apparent paradoxical behaviour of ubiquitous and abundant proteins that interact with defined DNA sites in spite of the lack of clear sequence consensuses. Considering firstly, that the interactions with DNA of both DNA topoisomerase I and histone octamers are topology‐sensitive and that upon their interaction the DNA conformation is modified; and secondly, that similar behaviours have also been reported for DNA topoisomerase II and histone H1, a topology‐based functional correlation among all these determinants of the higher order structure of chromatin is here suggested.

The US has built the most extensive immigration detention system globally. Over the last three administrations, several organizations have noted a systemic failure in the provision of health care in detention centers, leading to the torture and death of immigrants. This essay develops the principle of the preferential option for the poor to examine the causes of deficient access to health care and solutions to overcome them. It analyzes the substandard health care in detention centers from the notion (...) of structural violence and systematizes solutions of grassroots immigrant organizations from the idea of solidarity, understood here as a form of friendship with the poor that moves toward relational justice. Its goal is to build bridges between people so that the political will is generated to create policies to improve and enforce health care standards in detention centers and address the unjust foundations of immigration detention.

The DNase I hypersensitive sites (DHSs) of chromatin constitute one of the best landmarks of eukaryotic genes that are poised and/or activated for transcription. For over 35 years, the high‐mobility group nucleosome‐binding chromosomal proteins HMGN1 and HMGN2 have been shown to play a role in the establishment of these chromatin‐accessible domains at transcriptional regulatory elements, namely promoters and enhancers. The critical presence of HMGNs at enhancers, as highlighted by a recent publication, suggests a role for them in the structural and (...) functional fine‐tuning of the DHSs in vertebrates. As we review here, while preferentially out‐competing histone H1 binding and invading neighbor nucleosomes, HMGNs may also modulate histone H3 at serine 10 (H3S10ph), which plays an important role in enhancer function and transcriptional initiation.

Multiarm bandit problems have been used to model the selection of competing scientific theories by boundedly rational agents. In this paper, I define a variable-arm bandit problem, which allows the set of scientific theories to vary over time. I show that Roth-Erev reinforcement learning, which solves multiarm bandit problems in the limit, cannot solve this problem in a reasonable time. However, social learning via preferential attachment combined with individual reinforcement learning which discounts the past, does.

A sentence A is epistemically less entrenched in a belief state K than a sentence B if and only if a person in belief state K who is forced to give up either A or B will give up A and hold on to B. This is the fundamental idea of epistemic entrenchment as introduced by Gärdenfors (1988) and elaborated by Gärdenfors and Makinson (1988). Another distinguishing feature of relations of epistemic entrenchment is that they permit particularly simple and elegant (...) construction recipes for minimal changes of belief states. These relations, however, are required to satisfy rather demanding conditions. In the present paper we liberalize the concept of epistemic entrenchment by removing connectivity, minimality and maximality conditions. Correspondingly, we achieve a liberalization of the concept of rational belief change that does no longer presuppose the postulates of success and rational monotony. We show that the central results of Gärdenfors and Makinson are preserved in our more flexible setting. Moreover, the generalized concept of epistemic entrenchment turns out to be applicable also to relational and iterated belief changes. (shrink)

While hedonism has been subjected to much criticism over the years, it is still a widely endorsed axiological view. One objection that appears to be generally recognised as especially troublesome to hedonists is that their central claim, that final value accrues only to experiences of pleasure gives us a narrow view of value. Much more than pleasure is valuable for its own sake. A competing theory, preferentialism, is another widespread theory about value. According to one version of preferentialism, only the (...) objects of preferences carry final value, and since not all of our preferences have pleasure as their object, preferentialists accuse hedonists of overlooking a great deal that is of value. For instance, if someone has a so-called external preference to the effect that, say, the Californian redwood forests should go on existing, then the world contains more value if the forests continue to exist.1 Given this, the possible pleasure someone would experience on learning that his preference is satisfied has nothing to do with this kind of value. Preferentialists therefore conclude that the hedonist perspective is not wide enough. In this work, it is argued that hedonists are entitled to reverse the argument. Preferentialists are restrained by not being able to recognize the object of value that is cherished by hedonists. (shrink)

This paper studies the properties of eight semantic consequence relations defined from a Tarski-logic L and a preference relation ≺. They are equivalent to Shoham’s so-called preferential entailment for smooth model structures, but avoid certain problems of the latter in non-smooth configurations. Each of the logics can be characterized in terms of what we call multi-selection semantics. After discussing this type of semantics, we focus on some concrete proposals from the literature, checking a number of meta-theoretic properties and elaborating (...) on their intuitive motivation. As it turns out, many of their meta-properties only hold in case ≺ is transitive. To tackle this problem, we propose slight modifications of each of the systems, showing the resulting logics to behave better at the intuitive level and in metatheoretic terms, for arbitrary ≺.

It is widely believed that preferential hiring practices inevitably result in hiring less qualified candidates for jobs. Indeed, this follows analytically from some definitions of preferential hiring (e.g. George Sher's). This paper describes several preferential hiring strategies that do not have this consequence. Sher's definition is thus shown to be inadequate and an alternative definition is proposed.

An online game of chess against a human opponent appears to be indistinguishable from a game against a machine: both happen on the screen. Yet, people prefer to play chess against other people despite the fact that machines surpass people in skill. When the philosophers of 1970’s and 1980’s argued that computers will never surpass us in chess, perhaps their intuitions were rather saying “Computers will never be favored as opponents”? In this paper we analyse through the introduced concepts of (...) psychological affordances and psychological interplay, what are the mechanisms that make a human-human interaction more meaningful than a human-computer interaction. We claim that an HH chess game consists of two intertwined, but independent simultaneous games—only one of which is retained in the HC game. To help with the analysis we introduce the thought experiment of a Preferential Engagement Test which is inspired by, but non-equivalent to, the Standard Turing Test. We also explore how the PET can illuminate, and be illuminated by, various philosophies of mind reading: Theory Theory, Simulation Theory and Mind Minding. We propose that our analysis along with the concept of PET could illuminate in a new way the conditions and challenges a machine must face before it can replace humans in a given occupation.

We introduce Information Bearing Relation Systems (IBRS) as an abstraction of many logical systems. These are networks with arrows recursively leading to other arrows etc. We then define a general semantics for IBRS, and show that a special case of IBRS generalizes in a very natural way preferential semantics and solves open representation problems for weak logical systems. This is possible, as we can the strong coherence properties of preferential structures by higher arrows, that is, arrows, which do (...) not go to points, but to arrows themselves. (shrink)

I argue that there is an important sense in which God’s love is partial or preferential. In developing this argument, I appeal to Thomas Aquinas’s claim that God’s love for persons has the character of friendship. By its nature, friendship exhibits a considerable degree of partiality. For whether a person prefers to be united to another in friendship depends on whether the latter reciprocates the former’s affection and endorses those commitments conducive to fellowship. If God’s love is expressive of (...) friendship, then the sort of partiality some may wish to deny of his love may be one of its salient features. (shrink)

Handling exceptions in a knowledge-based system is an important issue in many application domains, such as medical domain. Recently, there is an increasing interest in nonmonotonic extension of description logics to handle exceptions in ontologies. In this paper, we propose three preferential semantics for plausible subsumption to deal with exceptions in description logic-based knowledge bases. Our preferential semantics are defined in the framework of possibility theory, which is an uncertainty theory devoted to handling incomplete information. We consider the (...) properties of these semantics and their relationships. We also discuss the relationship between two of our preferential semantics and two existing preferential semantics. We extend a description logic-based knowledge base by adding preferential subsumptions. Entailment of plausible subsumptions relative to an extended knowledge base is defined. Properties of the preferential subsumption relations relative to an extended description logic-based knowledge base are discussed. Finally, we show that our semantics for plausible subsumption can be reduced to standard semantics of an expressive description logic. Thus, the problem of plausible subsumption checking under our semantics can be reduced to the problem of subsumption checking under the classical semantics. (shrink)
