We prove that the problem of determining the minimum propositional proof length is NP- hard to approximate within a factor of 2 log 1 - o(1) n . These results are very robust in that they hold for almost all natural proof systems, including: Frege systems, extended Frege systems, resolution, Horn resolution, the polynomial calculus, the sequent calculus, the cut-free sequent calculus, as well as the polynomial calculus. Our hardness of approximation results usually apply to proof length measured either (...) by number of symbols or by number of inferences, for tree-like or dag-like proofs. We introduce the Monotone Minimum (Circuit) Satisfying Assignment problem and reduce it to the problems of approximation of the length of proofs. (shrink)

Our ability to select relevant information from the environment is limited by the resolution of attention – i.e., the minimum size of the region that can be selected. Neural mechanisms that underlie this limit and its development are not yet understood. Functional MRI was performed during an object tracking task in 7- and 11-year-old children, and in young adults. Object tracking activated canonical fronto-parietal attention systems and motion-sensitive area MT in children as young as 7 years. Object tracking performance (...) improved with age, together with stronger recruitment of parietal attention areas and a shift from low-level to higher-level visual areas. Increasing the required resolution of spatial attention – which was implemented by varying the distance between target and distractors in the object tracking task – led to activation increases in fronto-insular cortex, medial frontal cortex including anterior cingulate cortex (ACC) and supplementary motor area, superior colliculi, and thalamus. This core circuitry for attentional precision was recruited by all age groups, but ACC showed an age-related activation reduction. Our results suggest that age-related improvements in selective visual attention and in the resolution of attention are characterized by an increased use of more functionally specialized brain regions during the course of development.

Claims of progress in our ethical or moral beliefs and practices—as well as claims to ethical or moral regression—are commonplace in American social and political conversation. Often, such commentary involves a lamenting of the decline of “traditional” values in contemporary society or alternatively a rejoicing in the ways that we appear to have overcome prior prejudicial values. In this dissertation, I am concerned with the notions of progress and improvement that underlie such commonsense judgments. At a minimum, ethical progress (...) requires the idea that some values or practices are better than others and hence that replacing some beliefs or practices with others can be a genuine improvement. Taking inspiration from the ethical works of John Dewey, I sketch an account of evaluative progress that conceives of this sort of improvement in ethical beliefs or practices in terms of problem-resolving. On my view, resolving a problem involves both offering an adequate conception of the problem and finding a problem-solution which lives up to the world and to the values we reflectively endorse. On my account, resolving problems is not simply a matter of finding the best means to a fixed end; rather, I conceive of problem-resolving as a dynamic process in which ends themselves are typically in flux. The sort of “dynamic deliberation” I have in mind, then, goes beyond mere instrumental reasoning, by not only allowing us to recognize conflicts between ends or means to ends, but in also providing a way to rationally revise or reject ends. Finally, in order for this sort of problem-resolving to make good on the idea of genuine improvement or progress, the process of solving problems must involve some sense of objectivity. I offer a procedural account of objectivity that emphasizes the role of the world in constraining our inquiry, involves a naturalization of ethical epistemology, and allows for objective inquiry to be undertaken by an individual or a community.

It is widely held that Bayesian decision theory is the final word on how a rational person should make decisions. However, Leonard Savage--the inventor of Bayesian decision theory--argued that it would be ridiculous to use his theory outside the kind of small world in which it is always possible to "look before you leap." If taken seriously, this view makes Bayesian decision theory inappropriate for the large worlds of scientific discovery and macroeconomic enterprise. When is it correct to use Bayesian (...) decision theory--and when does it need to be modified? Using a minimum of mathematics, Rational Decisions clearly explains the foundations of Bayesian decision theory and shows why Savage restricted the theory's application to small worlds. The book is a wide-ranging exploration of standard theories of choice and belief under risk and uncertainty. Ken Binmore discusses the various philosophical attitudes related to the nature of probability and offers resolutions to paradoxes believed to hinder further progress. In arguing that the Bayesian approach to knowledge is inadequate in a large world, Binmore proposes an extension to Bayesian decision theory--allowing the idea of a mixed strategy in game theory to be expanded to a larger set of what Binmore refers to as "muddled" strategies. Written by one of the world's leading game theorists, Rational Decisions is the touchstone for anyone needing a concise, accessible, and expert view on Bayesian decision making. (shrink)

"Procedural Justice" offers a theory of procedural fairness for civil dispute resolution. The core idea behind the theory is the procedural legitimacy thesis: participation rights are essential for the legitimacy of adjudicatory procedures. The theory yields two principles of procedural justice: the accuracy principle and the participation principle. The two principles require a system of procedure to aim at accuracy and to afford reasonable rights of participation qualified by a practicability constraint. The Article begins in Part I, Introduction, with two (...) observations. First, the function of procedure is to particularize general substantive norms so that they can guide action. Second, the hard problem of procedural justice corresponds to the following question: How can we regard ourselves as obligated by legitimate authority to comply with a judgment that we believe (or even know) to be in error with respect to the substantive merits? The theory of procedural justice is developed in several stages, beginning with some preliminary questions and problems. The first question - what is procedure? - is the most difficult and requires an extensive answer: Part II, Substance and Procedure, defines the subject of the inquiry by offering a new theory of the distinction between substance and procedure that acknowledges the entanglement of the action-guiding roles of substantive and procedural rules while preserving the distinction between two ideal types of rules. The key to the development of this account of the nature of procedure is a thought experiment, in which we imagine a world with the maximum possible acoustic separation between substance and procedure. Part III, The Foundations of Procedural Justice, lays out the premises of general jurisprudence that ground the theory and answers a series of objections to the notion that the search for a theory of procedural justice is a worthwhile enterprise. Sections II and III set the stage for the more difficult work of constructing a theory of procedural legitimacy. Part IV, Views of Procedural Justice, investigates the theories of procedural fairness found explicitly or implicitly in case law and commentary. After a preliminary inquiry that distinguishes procedural justice from other forms of justice, Part IV focuses on three models or theories. The first, the accuracy model, assumes that the aim of civil dispute resolution is correct application of the law to the facts. The second, the balancing model, assumes that the aim of civil procedure is to strike a fair balance between the costs and benefits of adjudication. The third, the participation model, assumes that the very idea of a correct outcome must be understood as a function of process that guarantees fair and equal participation. Part IV demonstrates that none of these models provides the basis for a fully adequate theory of procedural justice. In Part V, The Value of Participation, the lessons learned from analysis and critique of the three models are then applied to the question whether a right of participation can be justified for reasons that are not reducible to either its effect on the accuracy or its effect on the cost of adjudication. The most important result of Part V is the Participatory Legitimacy Thesis: it is (usually) a condition for the fairness of a procedure that those who are to be finally bound shall have a reasonable opportunity to participate in the proceedings. The central normative thrust of Procedural Justice is developed in Part VI, Principles of Procedural Justice. The first principle, the Participation Principle, stipulates a minimum (and minimal) right of participation, in the form of notice and an opportunity to be heard, that must be satisfied (if feasible) in order for a procedure to be considered fair. The second principle, the Accuracy Principle, specifies the achievement of legally correct outcomes as the criterion for measuring procedural fairness, subject to four provisos, each of which sets out circumstances under which a departure from the goal of accuracy is justified by procedural fairness itself. In Part VII, The Problem of Aggregation, the Participation Principle and the Accuracy Principle are applied to the central problem of contemporary civil procedure - the aggregation of claims in mass litigation. Part VIII offers some concluding observations about the point and significance of Procedural Justice. (shrink)

The emergence of so-called ‘gig work’, particularly that sold through digital platforms accessed through smartphone apps, has led to disputes about the proper classification of workers: Should platform workers be classified as independent contractors (as platforms typically insist), or as employees of the platforms through which they sell labor (as workers often claim)? Such disputes have urgency due to the way in which employee status is necessary to access certain benefits such as a minimum wage, sick pay, and so (...) on. In addition, classification disputes have philosophical significance because their resolution requires some foundational account of why the law should make a distinction between employed and freelance workers in the first place. This paper aims to fill this foundational gap. Central to it is the idea that employment involves a worker ceding certain freedoms in return for a degree of security, at least with respect to income. Insofar as the misclassification objection has force against digital platforms, it is when a platform is attempting to have it both ways: Workers are giving up freedom but not being granted a proportionate increase in security. As I shall explain, this approach offers some flexibility as to how actual disputes might be resolved – justice may be indifferent between whether platforms offer greater security or permit workers greater freedom, provided they do at least one of these things.

Managers have a unique fiduciary responsibility to shareholders of a firm that implies a set of ethical obligations. At a minimum, managers are required to protect shareholder’s interests when other stakeholders are unaffected by their decision. This ethical imperative has been established in the literature. In cases of conflicts of interest between managers and shareholders, the board of directors of the firm has an ethical obligation to shareholders. The structure of the board can affect its ability to fulfill this (...) obligation. Two specific cases where managerial actions have been argued to be unethical are the adoption of classified boards and poison pills. In this study, we empirically analyze the role of board structure in protecting shareholder rights in the specific case of antitakeover provisions. We test this question on a sample of firms whose shareholders have voted to remove antitakeover provisions and find that independent, focused boards are more likely to accede to shareholder resolutions than are less independent boards. Board size is also important and related to other board structures. We draw implications of this finding for future research on the ethics of board governance.What’s really needed is a change in mindset—one that fosters not only a culture of compliance but also a company-wide environment that fosters ethical behavior and decision-making.—William H. Donaldson, SEC Chairman (2004). (shrink)

It is argued that physics must eventually expand to accommodate mind and consciousness but that this will require a new paradigm. The paradigm required will impinge on two problems on the borders of physics and philosophy: the relationship between physical space and perceptual space and the nature of the passage of time. It is argued that the resolution of both these problems may involve a 5-dimensional model, with the 5th dimension being associated with mental time, and this proposal may relate (...) to recent developments in brane cosmology. A description of consciousness must also entail a proper understanding of the specious present, the minimum timescale of conscious experience, this possibly being associated with a compactified extra dimension. There could even be a hierarchy of levels of consciousness, associated with a hierarchy of extra dimensions. (shrink)

In a supply chain system, the prices with which the suppliers supply its local commodity to the retailers should satisfy the requirements of the retailers and the consumers. The supply and demand scheme satisfying these requirements is reduced into fuzzy relation inequalities with min-product composition. Due to the difference between the min-product composition and the classical max-t-norm one, we first study the resolution of such min-product FRI system. For optimization management in the supply chain system, we further investigate a maximin (...) programming problem subject to the min-product FRIs. An algorithm is proposed to obtain the optimal solution based on the quasi-maximal matrix and corresponding index set. To illustrate the efficiency of our proposed algorithm, we provide a simple numerical example. The obtained optimal solution reflects an optimal pricing scheme, which maximizes the minimum prices of the commodity from the suppliers. (shrink)

Within modern liberal political philosophy, discussions on justice have been centered upon an individualism-based distributive justice and the ‘fair share’ due to each person. According to the liberal theory of justice, the individual is an entity of rational reason and moral autonomy and considers the interests of others and of the community from a viewpoint that is focused on one’s own interests. As practical principles of justice, the principle of desert has attempted to separate the individual’s natural and inherent abilities (...) (merit) from the individual’s intentional efforts (desert); while the principle of needs has transmuted into a set of minimum exclusivity rights to protect the individual’s autonomy from serious harm and injury. Procedural justice theorists such as Rawls have attempted to invalidate the merit of the individual in an attempt to establish the identity of individuals whom are independent of the community, in the effort to promote their ideas on how to mitigate the social inequality that results from natural arbitrariness. The requirement to finalize this logical process is astrong moral reason equipped individual with the capacity of rational action. However, paradoxically, the logic of excessive reason has created an individual who isexclusive-rights-empowered but becomes ‘isolated and selfish’. The issues resulting from this situation are, first, the rational individual who is equipped with moral autonomynow becomes hidden behind a system-guaranteed set of exclusive rights; and second, the individual who should have been a rational actor and actively participating in cooperation and reciprocal relationships, does not find it easy to overcome the temptations of becoming a strategically located but passive and selfish actor within the mass market order. The result is that individuals easily relinquish their moral autonomy and exhibit a tendency to focus on personal gain. This has resulted in an increase in the polarization of society, and an increase of conflict between classes; and has engendered a crisis in the common good of the family and the political community. The true ‘good life’ and the ‘well-ordered community’ cannot be obtained by individuals who are only interested in their ‘share’, but requires ‘good citizens’ who are concerned about the happiness of others and of the society. When we are able to understand that the rational and selfish individual is necessarily non-self-sufficient; and acknowledge that there is a need for mutual philia with others, we will then be able to overcome rational reason and embrace civic friendship. The good citizen of a healthy community that is based on civic friendship, is an individual who has assimilated the virtue of justice, and will be able to aid inovercoming the limitations of modern liberalism, assist in the resolution of the pressing societal and individualistic crises and contribute to theestablishment of a ‘well-ordered community’.

The authors review how attention helps track and process dynamic events, selecting and integrating information across time and space to produce a continuing identity for a moving, changing target. Rather than a fixed ‘spotlight’ that helps identify a static target, attention needs a mobile window or ‘pointer’ to track a moving target, picking up pieces of evidence along the way to determine not just what the target is, but what it is doing. Behavioural studies show that this dynamic version of (...) attention is model-based, using familiar trajectories to help identify a target and to guide encoding of continuing input from its path. Attention has very coarse temporal resolution for both static and moving targets. However, when the focus of selection is on the move, a given location on a moving target’s path can be selected for extremely brief instants, as little as 50 ms, compared to the typical ‘dwell time’ or minimum duration of attention selection at a fixed location, of 200 ms or more. To determine the path of a moving object, attention must accurately process and sort the onsets and offsets in order to match an offset to the subsequent onset. This aspect of dynamic attention has been called the ‘when’ pathway and patient studies show that it is a qualitatively different system from spatial attention, being completely based in the right parietal lobe for events in both hemifields. Finally, like the salience map of spatial attention, temporal attention may have its own map that guides allocation to upcoming, current, and recent moments to select information at the appropriate time, changing the experience of time as it does so.

As the title of the article suggests, “The Burqa Ban”: Legal Precursors for Denmark, American Experiences and Experiments, and Philosophical and Critical Examinations, the authors embark on a factually investigative as well as a reflective response. More precisely, they use The 2018 Danish “Burqa Ban”: Joining a European Trend and Sending a National Message (published as a concurrent but separate article in this issue of INTERNATIONAL STUDIES JOURNAL) as a platform for further analysis and discussion of different perspectives. These include (...) case-law at the international level while focusing attention on recent rulings and judicial reasoning by the ECtHR and the ECJ; critical thought-experiments in religion, morality, human rights, and the democratic public space; a contextualized account of burqa-wearing interventions by federal and state governments and, moreover, various courts in the United States; and philosophical commentary and, in some instances, criticism of the Danish and/or European (French, etc.) approach. The different contributions have different aims. The section on case-law at the international level reports on those central judgments that, in effect, helped to pave the path for the Kingdom of Denmark’s burqa ban. Concerning the concurring judges at the ECtHR, the opinions served to uphold a preexisting ban and to grant a wide margin of appreciation to the national authorities, thereby limiting the Court’s own review. -/- As regards to the ECJ, the legality of company rules that contain a policy of neutrality for the workplace was examined, with a similar outcome. The authors who discuss religion, morality, human rights and the democratic public space are endeavoring to, respectively, appeal to ethics as a testing stone for law and to both challenge and address several forms of “expressivist worry” in connection with face veils. In doing so, the authors ask a number of thought-provoking questions that hopefully will inspire public policymakers to careful analysis. While the section that is devoted to American perspectives highlights a comprehensive survey of political and legal responses to, in particular, full-face veils like the burqa, the relevant author also incorporates public perceptions and, in the course of examining these, draws a parallel to “the fate” of the hoodie. The constitutionality of burqa-wearing in America, so it also appears, is partially an open question, but differentiating between religious, political, or personal reasons is a de jure premise. Given that the Danish legislators who drafted law L 219 to ban burqa-wearing in public places rely on a reference to political Islam, they relegate religious and personal reasons to the private domain, thereby also adopting secularism as a premise. This is explored in the last author response of the article, more precisely, in an account of the underlying materialism that, in turn, is applied to Muslim women. If policymakers and legislators engaged in Thinking Things Through exercises, they could, as a minimum, avoid law-making strategies that are not in the spirit of the theory they themselves invoke, albeit tacitly. While the aim of, as it were, arresting culturally self-contradicting legislators is unique for the section in question, all the authors who contribute to the joint research project have one end-goal in common, namely to inform about important perspectives while at the same time opening up for parameters for (more) fruitful, constructive and (if need be) critical debate in the future. With this in mind, four recommendations are presented by the research director for the project. Legally, politically, socially and culturally, conflict-resolution should not translate the relationship between rulers and the ruled into a separation ideology, an instance of controllers versus the controlled. All things being equal, that is the objective limit for a democratic society. (shrink)

The question of whether phenomenal consciousness is limited to the capacity of cognitive access remains a contentious issue in philosophy. Overflow theorists argue that the capacity of conscious experience outstrips the capacity of cognitive access. This paper demonstrates a resolution to the overflow debate is found in acknowledging a difference in phenomenological timing required by both sides. It makes clear that the “no overflow” view requires subjects to, at the bare minimum, generate an unconscious visual image of previously presented (...) items if it is to explain performance in the change detection paradigm. It then demonstrates that conscious imagery should support better task performance than unconscious imagery because of a necessary difference in representational strength. However, this contradicts empirical findings, and so a new argument for overflow is presented without requiring the premise that subjects need to obtain a specific phenomenology of presented items during change detection.

Perforation or gap formation in a vegetation is a major process in landscape transformation. The occurrence of gaps profoundly alters the microclimatical conditions in a vegetation. A method is proposed to quantify perforation by using the three main 2-D characteristics of the gaps: area, number and boundary length. New measures are developed by normalizing the observed values to the reference status of minimum and maximum perforation. As minimum perforation status, the presence of one single gap with area equal (...) to the map resolution is assumed. The new measures are combined using a 3-D Euclidean distance to visualize the process and to detect changes. The method is exemplified using a field case of gaps in a tropical terra firme rainforest at Tiputini, Ecuador. (shrink)

In this discussion of Seyla Benhabib’s Claims of Culture, I defend a more pluralist conception of deliberative democracy and a stronger conception of the cosmopolitan content of human rights. I will discuss three main issues: first, problems of incommensurability and deep conflict; second, the role of impartiality and normative constraints embodied in the ‘syntactic’ and ‘semantic’ interpretations of the deliberative formula ‘reasons that all could accept’; and third, the differences in our conceptions of cosmopolitanism and the status of rightless persons, (...) particularly as illustrated through the example of the European Union. In the first two cases, I argue that the democratic minimum required for the resolution of second-order conflicts without domination demands a weaker interpretation of procedural norms of deliberation; in the case of rightless persons, I argue that the ‘right of hospitality’ that Benhabib employs is not robust enough and that there is more content to the conception of human rights that is applicable to the fate of refugees, asylum seekers, and other stateless persons.

This article considers proposals to reform the law in response to recent high profile cases concerning the medical treatment of children, currently before Parliament in the Access to Palliative Care and Treatment of Children Bill 2019–21. It considers the proposed procedural change, to introduce a requirement for mediation before court proceedings, and argues that dispute resolution processes should be a matter of good practice rather than enshrined in law. It argues that the proposed substantive change to determination of best interests (...) would not result in different outcomes because the best interests analysis co-exist with the legal and professional duties of doctors to children in their care. It argues that if there is to be reform of the law it needs to follow from a comprehensive review of all the issues in which the minimum standards imposed by law fit together with good practice standards and not in response to individual cases.

In lieu of an abstract, here is a brief excerpt of the content:Principles and PragmatismR. Alta Charo (bio)Openly, privately, or implicitly, every public ethics committee struggles with its mandate. Is its job to identify a moral ideal?; a morally acceptable minimum that, realistically, could be adopted as policy?; or an optimal political compromise that can arguably meet ethical analysis? The answer appears to be different for each committee, depending upon its subject matter, its sponsoring political body, and the details (...) of its legal mandate. What is universal, however, is that even the most well-intentioned committee is likely to experience dissension over the interpretation of its task and that this dissension will often be played out in debates over particular policy recommendations.Ruth Macklin’s description of disagreement and moral integrity in the context of the Advisory Committee on Human Radiation Experiments demonstrates this phenomenon quite clearly (Macklin 1996). The epistemological debates concerning the evidence of past practices illuminate differing visions of the Committee’s mandate. For some it was to render moral judgment on past acts, without necessarily concluding that, if the acts were immoral, the individuals involved were themselves immoral. For others it was to use moral judgments to determine appropriate forms of restitution, thus balancing the reputational risks to past actors against the need for and feasibility of restitution to the victims. Still others appeared to focus on crafting specific political responses, and the historical data needed only be sufficient to bolster the policy recommendations.In this respect, the composition of any advisory committee becomes crucial. As fact-finders, committee members must determine the kind of evidence they will find persuasive. This determination, in turn, depends upon whether the committee sees itself primarily as (1) informational, in which case the standards employed by professional historians are probably the most appropriate, or (2) judgmental, in which case something closer to legal standards of proof might be better. The dilemma is not limited to committees looking at history; those rendering advice on science policy need to determine if they will use standards of proof prevalent in the scientific community (consensus following peer review) or the public (scientific consensus coupled with credibility of the scientific community as a whole). [End Page 319]When a committee is asked to base its judgments on ethical analysis, the conflicts only deepen. The “ethics” of policy recommendations are invariably balanced against the desire to see one’s work yield a concrete political response, the perception of political constraints on implementing an ethically “ideal” solution, and the subtle pressures exerted by the sponsoring political body to respond to the specific committee mandate, which was written with the needs of the sponsoring body in mind, not the needs of a wide-ranging ethics discussion.Another complication arises because ethics committees derive their credibility from the perception that moral truth is discoverable and unassailable. To horse trade among these moral truths undermines the credibility of their entire endeavor and can render bioethics advisory committees not only ineffective but even offensive. After all, if a moral truth exists, how ethical is it for “ethicists” to abandon it in the name of strategic concerns? If, on the other hand, no moral truth exists, then by what right do these “ethics” committees claim persuasive authority beyond that of any citizen advisory committee?This is a deep dilemma that relates to the discipline of bioethics itself. Lacking a core methodology or doctrine, bioethics has yet to justify itself to either its proponents or to the public. Bioethics scholars acknowledge that there are a variety of theories drawn from moral philosophy that could be used to guide the resolution of dilemmas that arise in the context of medical care and biomedical research. Such theories include utilitarianism, deontology, teleology, virtue theory, and justice theory, with no one theory being universally adopted by bioethics scholars and no one methodology being available to resolve conflicts among their respective conclusions. While deductivism is the predominant analytical style in the field, “[t]he central difficulty with deductivism is that there is no single comprehensive moral theory, nor even theories or principles of more limited scope, which is agreed to be true or correct” from which defensible conclusions will flow (Brock 1995).But if public ethics bodies cannot...

Food is a big business in the EU and nanofood products are beginning to be placed on the market. It is still unclear whether the absence of minimum regulation at a global level promotes or prevents the growth of a market in nanofood. However, the development of an adequate risk management policy in relation to food safety is a key concern for consumers. Importantly, the European Parliament in its 2009 Resolution on “Legal aspects on nanomaterials” called for more in-depth (...) scientific research on the toxicity of compounds in nanomaterials, and for the adoption of an EU definition of nanomaterials for regulatory purposes. Unfortunately, in 2011, nanotechnology led to inconclusive debates in the context of the revision of Novel Food Regulation. General Food Law applies to nanofood in terms of safety requirements, and specific rules also apply to food contact materials containing nanoparticles as well as to to additives, vitamins and minerals. The EU legislator also introduced mandatory labelling in respect of products derived from nanotechnologies. The legal framework is evolving according to the so-called “incremental approach”, a governance model that creates the risk of fragmentation. But the main problem is the inconsistent definition of the terms “nanotechnology” and “nanomaterials” when looking at the enforcement of regulations and the provision of a wide range of specific tools for different nanofoods: for example the use of positive lists of authorised substances applying only to food contact materials, additives and supplements. This contribution aims to review the regulations in force in respect to nanofood and novel foods and to highlight the problems that are still unresolved. (shrink)

What I have tried to do here is to provide a historical example of the interdependence between nature and culture that is one of the themes of this conference. To sum up: Scientific descriptions of the world emerge out of a complex interaction between nature, economic production, and the legal system. “Science” consists of a struggle among scientists, and between scientists and citizens, over what counts as “reality.” Lawmaking, in turn, consists of a struggle between people who want to allocate (...) access to resources for particular purposes, whether for commercial use, recreational use, or “natural” uses. Production, for its part, is a complicated function of technology, the sociology of user groups, the structure of legal entitlements to access, and the availability of resources. Nature, finally, is at any point, to no small degree, the product of past and present human impacts on it — which impacts, in turn, are determined in no small way by the sociology and the legal structure of the market.Each process takes place in continual conversation with all the others. As John Muir put it, “When we try to pick out anything by itself, we find it hitched to everything else in the universe.”45 Historically, resource managers have gotten into trouble when they have unconsciously assumed that such is not the case — yet such, assumptions are powerful because they are made instinctively, unthinkingly, at the level of people's basic understanding of the world and their place in it. Lots of them persist.On the other hand, in a few experimental cases in the United States and Canada where government and users have shared power and responsibility for resources management, including long-range planning for recovery and enhancement, here have been some notable improvements. The strategy goes under the name of “co-management” and involves negotiated agreements for shared decision-making between central authority and local groups. Typically, both government and industry resist such arrangements because they involve restructuring the power relations between different sectors in the industry; the result is that the few experiments in co-management that we have seen in the United States have come in areas, typically fisheries and wildlife, where the resource is in serious crisis and all of the parties to the agreement have had to abandon the positions they held previously.Examples of successful co-management regimes include those among American tribes in the Pacific Northwest, among commercial salmon fishers in Alaska, and in a project to rehabilitate the clam industry in New Jersey. Government employees and local groups share responsibility for gathering scientific data about the resources, for developing plans to manage them, and for enforcing regulations. Successful experiments at co-management seem to generate better scientific data about their resources than traditional management regimes do; they significantly reduce enforcement costs; and they enhance the economic power of the resource users. Most importantly, they nurture among the user groups a sense of control over their own destinies, and a willingness to share both costs and benefits of managing the resources rationally and to develop lasting, stable mechanisms for conflict resolution. The process is both democratic and ecologically rational. The key is to link the day-to-day work of producers to their long-range interests as residents in their communities and as working parts of the ecological systems in which they live.45At a minimum, it is clear that objective certainty about the state of the resources or the likely effect of whatever regulations we do impose is simply not attainable. This is partly because of the important role that random shocks play in the environment (and should play in our thinking about it), and also because of the sheer complexity of the system in which we are embedded. There will always be something that even the most complete model leaves out; and in any event the total system of ecology, production, and management will change every time something changes in any part of it.The policy lesson to be derived from all of this, finally, is that what we ought to sustain when we approach conservation problems is not the size of a particular resource, or even the prosperity of a particular harvesting group, but the long-term health of the interaction between nature, the economy, and the political system. We can recognize that the balance of the system, our attempted insurance against an uncertain future, democracy among user groups, and our moral duty to avoid extinguishing species — all of these things being difficult to quantify — do play integral roles in the conversation between nature and humankind, and perhaps more significant roles than the more objective measures to which we usually look for guidance. We can recognize, as John Muir did, that because everything in the universe is hitched to everything else, every step we take will change the total system in some way. When we make choices, then, we can keep an eye on what kind of conversation we want to have with the rest of Creation and make our choices accordingly. *** DIRECT SUPPORT *** A8402064 00014 *** DIRECT SUPPORT *** A8402064 00015.

Animal data suggest that jet fuels such as JP-8 are associated with hearing deficits when combined with noise and that the effect is more pronounced than with noise exposure alone. Some studies suggest peripheral dysfunction while others suggest central auditory dysfunction. Human data are limited in this regard. The aim of this study was to investigate the possible chronic adverse effects of JP-8 combined with noise exposure on the peripheral and central auditory systems in humans. Fifty-seven participants who were current (...) personnel from the Royal Australian Air Force were selected. Based on their levels of exposure to jet fuels, participants were divided into three exposure groups. Groups were also categorised based on their noise exposure levels. All participants were evaluated by tympanometry, pure-tone audiometry, distortion product otoacoustic emissions, auditory brainstem response, words-in-noise, compressed speech, dichotic digit test, pitch pattern sequence test, duration pattern sequence test and adaptive test of temporal resolution. All auditory tests were carried out after the participants were away from the Air Force base for a minimum of two weeks, thus two weeks without jet fuel and noise exposure. Jet fuel exposure was significantly associated with hearing thresholds at 4 and 8 kHz; average hearing thresholds across frequencies in the better ear; DPOAEs at 2.8, 4 and 6 kHz; ABR wave V latency in the right ear; compressed speech and words-in-noise. Further analyses revealed that participants with low exposure level to jet fuels showed significantly better results for the aforementioned procedures than participants with moderate and high exposure levels. All results were controlled for the covariates of age and noise exposure levels. The results suggest that jet fuel exposure, when combined with noise exposure, has an adverse effect on audibility in humans. Taking all the test results into consideration, jet fuel exposure combined with noise exposure specifically seems to affect the peripheral hearing system in humans. (shrink)

Light sheet microscopy is an easy to implement and extremely powerful alternative to established fluorescence imaging techniques such as laser scanning confocal, multi‐photon and spinning disk microscopy. By illuminating the sample only with a thin slice of light, photo‐bleaching is reduced to a minimum, making light sheet microscopy ideal for non‐destructive imaging of fragile samples over extended periods of time. Millimeter‐sized samples can be imaged rapidly with high resolution and high depth penetration. A large variety of instruments have been (...) developed and optimized for a number of different samples: Bessel beams form thin light sheets for single cells, and selective plane illumination microscopy (SPIM) offers multi‐view acquisition to image entire embryos with isotropic resolution. This review explains how light sheet microscopy involves a conceptually new microscope design and how it changes modern imaging in biology. (shrink)

BackgroundThe neural activity and functional networks of emotion-based cognitive reappraisal have been widely investigated using electroencephalography and functional magnetic resonance imaging. However, single-mode neuroimaging techniques are limited in exploring the regulation process with high temporal and spatial resolution.ObjectivesWe proposed a source localization method with multimodal integration of EEG and fMRI and tested it in the source-level functional network analysis of emotion cognitive reappraisal.MethodsEEG and fMRI data were simultaneously recorded when 15 subjects were performing the emotional cognitive reappraisal task. Fused priori (...) weighted minimum norm estimation with sliding windows was proposed to trace the dynamics of EEG source activities, and the phase lag index was used to construct the functional brain network associated with the process of downregulating negative affect using the reappraisal strategy.ResultsThe functional networks were constructed with the measure of PLI, in which the important regions were indicated. In the gamma band source-level network analysis, the cuneus, the lateral orbitofrontal cortex, the superior parietal cortex, the postcentral gyrus, and the pars opercularis were identified as important regions in reappraisal with high betweenness centrality.ConclusionThe proposed multimodal integration method for source localization identified the key cortices involved in emotion regulation, and the network analysis demonstrated the important brain regions involved in the cognitive control of reappraisal. It shows promise in the utility in the clinical setting for affective disorders. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE ROLE OF AN ULTIMATE AUTHORITY IN RESTORATIVE JUSTICE: A GIRARDIAN ANALYSIS Sara Osborne I. Restorative or Retributive Justice South African Episcopal Archbishop Desmond Mpilo Tutu's account of the gritty practicality of reconciliation versus retribution in his book, No Future Without Forgiveness, focuses long overdue attention on Restorative Justice, a law reform movement probably better known in international than in American legal circles. A persuasive assertion of Restorative Justice (...) advocates in their critique of increasingly retributive practices such as mandatory minimum sentencing, mandatory arrest, death penalty, juvenile incarceration, "three strikes" legislation, no parole, diminished prisoner services, to name a few, is that reintegrating offenders back into a community is a much more effective deterrence to anti-social violence than punishment alone. They have also observed that communitarian ideals and practices, more visible in traditional cultures1 are more conducive to Restorative goals ofreconciliation and reintegration than are practices of retributive justice rooted in ideals of individual rights. Therefore, such adjudicatory practices should serve as models for preferable alternatives. 1An examination ofrestorative justice under code-based systems of law (European, Roman Law) might also reveal more affinities since the focus ofthese systems is to define the permissible, rather than the impermissible. Code-based law begins with the commons; rightsbased law begins with the individual. 80Sara Osborne However, Western-style retributive justice remains the primary model for international law and Restorative Justice is the prophetic "outsider" voice. So, it is appropriate to ask to what extent and under what conditions are Western retributive justice systems able to incorporate or accommodate adjudicatory practices ofnon-Western or traditional cultures? How critical a factor is religion? These questions will appear wherever Western Law struggles to bring more cultural diversity under a unifying umbrella and they deserve close scrutiny. René Girard's insights into the relationship between law, religion, culture and violence are helpful in identifying practical implications ofthe restorative vision and systemic weaknesses ofretribution, and perhaps illuminating a third way. The metaphor of an organ transplant may be useful: without a genetic match between host and donor both risk destruction. It is the thesis of this paper that that genetic material is a very inclusive conceptualization of "religion" which I have named "Ultimate Authority," drawing on Girard's mimetic theory for the theoretical analysis. In other words, "religion" is indeed, always and everywhere, a critical factor in culture-specific institutions ofjustice. A Girardian understanding ofthe relationship between Ultimate Authority and criminaljustice systems indicates that while there are valuable lessons to be learned from trans-cultural dialogue, wholesale transplants may not be possible, or even advisable because conditions essential for comparable success do not exist in Western legal culture. This paper first presents some background about Restorative Justice, followed by an outline ofRené Girard's mimetic theory to define "Ultimate Authority." The second half of the paper describes alternative adjudicatory processes which have attracted the attention of Restorative Justice advocates and concludes with suggestions about future directions for criminal justice policy discussion. Restorative Justice is a movement which drew its initial energy from Civil Rights era non-violent social action. It has found avid supporters among those whose activism for socialjustice is faith-based as well as those whose activism is rooted in more secular communitarian ideologies. Perhaps because of its international following, a significant contribution ofthe movement has been to initiate trans-cultural dialogue about criminal justice, fostering an increased use of alternative dispute resolution techniques, primarily mediation. Restorative Justice doctrine insists that all crime is personal, evidence ofa broken relationship between victim, offender, and community. Restoring "right relationship" between all parties is both a moral and legal obligation; "justice" to be just must go well beyond addressing the specifics of the act which effected the break. In contrast, the focus of The Role ofAn Ultimate Authority81 retributive justice appears abstract, procedural, and narrow in pursuit of impartiality or neutrality, the ideal of Blind Justice.2 Howard Zehr, a consultant on criminal justice and a Canadian Mennonite who wrote the classic Restorative Justice primer, Changing Lenses: A New Focusfor Crime andJustice, describes the retributive criminaljustice process as "a drama between two abstractions," meaning a criminal and a victim, where the "victim" is even further abstracted...

Biomedical research has a strong impact on a country’s scientific-technological and socioeconomic development. It can make a significant contribution at three different levels: promotion of public health; the exchange of knowledge within the scientific community; and economic/ financial profitability. Africa only attracts ~3.3% of the world’s clinical research. This small proportion is due to, among several factors, the absence of two fundamental aspects: specific robust legislation and capacity for regulatory and ethical evaluation. There are five Portuguese- speaking African countries – (...) Angola, Cabo Verde, Guinea-Bissau, Mozambique and São Tomé and Príncipe. Despite presenting different degrees of clinical research development, these countries show a common serious insufficiency in the minimum conditions necessary for hosting, collaborating or leading biomedical research projects. These countries are also excluded from the support of international organisations for capacity building because of the language barrier. The Biomedical Ethics and Regulatory Capacity Building Partnership for Portuguese-Speaking African Countries project has developed methods to build capacity and partnership through research on national law, comparisons with international standards and by issuing recommendations at a national level. Through collaborative intensive training, trainees are taught to become educators at a national level. This, in turn, creates a sustainable impact at country level. BERC-Luso is a pioneering project, owing to a combination of innovative features. The partnership project: was developed exclusively in Portuguese; involves a large number of African countries, and national and international institutions; has been further enhanced by the diversity and complementarity of its action plans; and has also benefited from a broad participatory methodology based on resolution of recipients’ problems by the recipients themselves. It thus stands out as a model for similar future projects. (shrink)

Mandatory minimum sentencing provisions have been a feature of the U.S. justice system since 1790. But they have expanded considerably under the war on drugs, and their use has expanded considerably under the Trump Administration; some states are also poised to expand drug-related mandatory minimums further in efforts to fight the current opioid epidemic. In this paper I outline and evaluate three prominent arguments for and against the use of mandatory minimums in the war on drugs—they appeal, respectively, to (...) proportionality, consistency, and efficiency. I ultimately defend the view that the use of mandatory minimums in the war on drugs is unjust. -/- . (shrink)

Minimum deterrence, though consistent with the nonaggression principle, is inadequate to deter states from invading anarchist territory and provides inadequate means of territorial defense when deterrence fails. In order to be effective, and thus attract clients, private defense agencies may want to adopt a military posture that incorporates first-strike counterforce and second-strike countervalue capabilities. To this end, they must acquire weapons of mass destruction—including tactical and strategic nuclear weapons—and long-range delivery vehicles capable of penetrating deep into enemy territory. They (...) must also decline to extend the nonaggression principle to states and individuals outside the voluntary defense network. Paradoxically, advertising such a posture while possessing a nuclear arsenal will save lives on both sides by minimizing the probability that anarchists must ever wage a defensive war at all.

Abstract: “Resolute readings” initially started life as a radical new approach to Wittgenstein's early philosophy, but are now starting to take root as a way of interpreting the later writings as well—a trend exemplified by Stephen Mulhall's Wittgenstein's Private Language (2007) as well as by Phil Hutchinson's “What's the Point of Elucidation?” (2007) and Rom Harré's “Grammatical Therapy and the Third Wittgenstein” (2008). The present article shows that there are neither good philosophical nor compelling exegetical grounds for accepting a resolute (...) reading of the later Wittgenstein's work. It is possible to make sense of Wittgenstein's philosophical method without either ascribing to him an incoherent conception of “substantial nonsense” or espousing the resolute readers' preferred option of nonsense austerity. If the interpretation here is correct, it allows us to recognize Wittgenstein's radical break with the philosophical tradition without having to characterize his achievements in purely therapeutic fashion.

Given its non-invasive nature, there is increasing interest in the use of transcutaneous vagus nerve stimulation across basic, translational and clinical research. Contemporaneously, tVNS can be achieved by stimulating either the auricular branch or the cervical bundle of the vagus nerve, referred to as transcutaneous auricular vagus nerve stimulation and transcutaneous cervical VNS, respectively. In order to advance the field in a systematic manner, studies using these technologies need to adequately report sufficient methodological detail to enable comparison of results between (...) studies, replication of studies, as well as enhancing study participant safety. We systematically reviewed the existing tVNS literature to evaluate current reporting practices. Based on this review, and consensus among participating authors, we propose a set of minimal reporting items to guide future tVNS studies. The suggested items address specific technical aspects of the device and stimulation parameters. We also cover general recommendations including inclusion and exclusion criteria for participants, outcome parameters and the detailed reporting of side effects. Furthermore, we review strategies used to identify the optimal stimulation parameters for a given research setting and summarize ongoing developments in animal research with potential implications for the application of tVNS in humans. Finally, we discuss the potential of tVNS in future research as well as the associated challenges across several disciplines in research and clinical practice. (shrink)

The aim of this paper is to present and discuss the issue of the adequacy of the Minimum Intelligent Signal Test (MIST) as an alternative to the Turing Test. MIST has been proposed by Chris McKinstry as a better alternative to Turing’s original idea. Two of the main claims about MIST are that (1) MIST questions exploit commonsense knowledge and as a result are expected to be easy to answer for human beings and difficult for computer programs; and that (...) (2) the MIST design aims at eliminating the problem of the role of judges in the test. To discuss these design assumptions we will present Peter D. Turney’s PMI-IR algorithm which allows for MIST-type questions to be answered. We will also present and discuss the results of our own study aimed at the judge problem for MIST. (shrink)

The use of super‐resolution imaging techniques in cell biology has yielded a wealth of information regarding cellular elements and processes that were invisible to conventional imaging. Focusing on images obtained by stimulated emission depletion (STED) microscopy, we discuss how the new high‐resolution data influence the ways in which we use and interpret images in cell biology. Super‐resolution images have lent support to some of our current hypotheses. But, more significantly, they have revealed unexpectedly complex processes that cannot be accounted for (...) by the simpler models based on diffraction‐limited imaging. The super‐resolution imaging data challenge cell biologists to change their theoretical framework, by including, for instance, interpretations that describe multiple functions, functional errors or lack of function for cellular elements. In this context, we argue that descriptive research using super‐resolution microscopy is now as necessary as hypothesis‐driven research. (shrink)

This article discusses interactive minimum cost spanning tree problems and argues that the standard approach of using a transferable utility game to come up with a fair allocation of the total costs has some flaws. A new model of spillover games is presented, in which each player’s decision whether or not to cooperate is properly taken into account.

In this article I investigate the phenomenon of minimum and minimal models of second-order set theories, focusing on Kelley–Morse set theory KM, Gödel–Bernays set theory GB, and GB augmented with the principle of Elementary Transfinite Recursion. The main results are the following. (1) A countable model of ZFC has a minimum GBC-realization if and only if it admits a parametrically definable global well order. (2) Countable models of GBC admit minimal extensions with the same sets. (3) There is (...) no minimum transitive model of KM. (4) There is a minimum β-model of GB+ETR. The main question left unanswered by this article is whether there is a minimum transitive model of GB+ETR. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data (...) sets them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

In Willing, Wanting, Waiting, Richard Holton lays out a detailed account of resolutions, arguing that they enable agents to resist temptation. Holton claims that temptation often leads to inappropriate shifts in judgment, and that resolutions are a special kind of first- and second-order intention pair that blocks such judgment shift. In this paper, I elaborate upon an intuitive but underdeveloped objection to Holton’s view – namely, that his view does not enable agents to successfully block the transmission of temptation in (...) the way that he claims, because the second-order intention is as equally susceptible to temptation as the first-order intention alone would be. I appeal to independently compelling principles – principles that Holton should accept, because they help fill an important explanatory gap in his account – to demonstrate why this objection succeeds. This argument both shows us where Holton’s view goes wrong and points us to the kind of solu-tion we need. In conclusion, I sketch an alternative account of resolutions as a first-order intention paired with a second-order desire. I argue that my account is not susceptible to the same objection because a temptation that cannot be blocked by an intention can be blocked by a desire. (shrink)

A minimum voting age is defended as the most effective and least disrespectful means of ensuring all members of an electorate are sufficiently competent to vote. Whilst it may be reasonable to require competency from voters, a minimum voting age should be rejected because its view of competence is unreasonably controversial, it is incapable of defining a clear threshold of sufficiency and an alternative test is available which treats children more respectfully. This alternative is a procedural test for (...) minimum electoral competence. A procedural test for minimum electoral competence also succeeds in fulfilling adults’ duties to promote children’s rational and moral engagement with democracy. A minimum voting age should therefore be rejected, all things considered. A procedural test for minimum literacy and independent voting is the most justified means to ensure competency from voters and to promote the democratic agency of children. (shrink)

Poverty in Africa has gained the attention of social activists, Non-Governmental Organizations, scholars from diverse fields, as well as governments. The contemporary reality of poverty, as revealed by various indices, shows that this problem has resisted the interventions so far. In view of the failures of earlier and current approaches to alleviating poverty in Africa, this paper explores the ethical and prudential approaches to setting anew, viable trajectory for poverty alleviation in twenty-first century Africa. It raises the fundamental question of (...) whether or not the affluent individuals in African societies on the one hand, and the wealthy Western nations on the other have any obligation towards the poor in Africa. On the basis of a critical consideration of some ethical theories in relation to the question of poverty, the paper contends that for the sake of stability and progress in the continent, it is necessary to develop programmes for the effectiveassistance of the poor on altruistic and prudential grounds.
