Unresponsive wakefulness syndrome (UWS, previously known as vegetative state) occurs after patients survive a severe brain injury. Patients suffering from UWS have lost awareness of themselves and of the external environment and do not retain any trace of their subjective experience. Current data demonstrate that neuronal functions subtending consciousness are not completely reset in UWS; however, they are reduced below the threshold required to experience consciousness. The critical factor that determines whether patients will recover consciousness is the distance of (...) their neuronal functions from this threshold level. Recovery of consciousness occurs through functional and/or structural changes in the brain, i.e., through neuronal plasticity. Although some of these changes may occur spontaneously, a growing body of evidence indicates that rehabilitative interventions can improve functional outcome by promoting adaptive functional and structural plasticity in the brain, especially if a comprehensive neurophysiological theory of consciousness is followed. In this review we will focus on the pathophysiological mechanisms involved in UWS and on the plastic changes operating on the recovery of consciousness. (shrink)

This paper provides an axiomatic analysis of sufficientarian social evaluation. Sufficientarianism has emerged as an increasingly important notion of distributive justice. We propose a class of principles that we label generalized critical-level sufficientarian orderings. The distinguishing feature of our new class is that its members exhibit constant critical levels of well-being that are allowed to differ from the threshold of sufficiency. Our basic axiom assigns priority to those below the threshold, a property that is shared by numerous (...) other sufficientarian approaches. When combined with the well-known strong Pareto principle and the assumption that there be a constant critical level, the axiom implies that the critical level cannot be below the threshold. The main results of the paper are characterizations of our new class and an important subclass. As a final observation, we identify the generalized critical-level sufficientarian orderings that permit us to avoid the repugnant conclusion and the sadistic conclusion, which are known as two fundamental challenges in population ethics.

Application of egalitarian and prioritarian accounts of health resource allocation in low‐income countries have both been criticized for implying distribution outcomes that allow decreasing/undermining health gains and for tolerating unacceptable standards of health care and health status that result from such allocation schemes. Insufficient health care and severe deprivation of health resources are difficult to accept even when justified by aggregative efficiency or legitimized by fair deliberative process in pursuing equality and priority oriented outcomes. I affirm the sufficientarian argument that, (...) given extreme scarcity of public health resources in low‐income countries, neither health status equality between populations nor priority for the worse off is normatively adequate. Nevertheless, the threshold norm alone need not be the sole consideration when a country's total health budget is extremely scarce. Threshold considerations are necessary in developing a theory of fair distribution of health resources that is sensitive to the lexically prior norm of sufficiency. Based on the intuition that shares must not be taken away from those who barely achieve a minimal level of health, I argue that assessments based on standards of minimal physical/mental health must be developed to evaluate the sufficiency of the total resources of health systems in low‐income countries prior to pursuing equality, priority, and efficiency based resource allocation. I also begin to examine how threshold sensitive health resource assessment could be used in the Philippines. (shrink)

The Threshold of the Visible World advances a revolutionary new political aesthetic--Kaja Silverman explores the possibilities for looking beyond the restrictive mandates of the self, and the normative aspects of the cultural image-repertoire. She provides a detailed account of the social and psychic forces which constrain us to look and identify in normative ways, and the violence which that normativity implies. Accounting for these phenomena on both a conscious and an unconcious level, Silverman analyzes the psychic and textual (...) conditions under which our "field of vision" can be expanded. The title of this book is taken from Lacan's essay on the mirror stage. In that text, Lacan writes that "the mirror-image would seem to be the threshold of the visible world." He thereby suggests that the visible world has no existence as such until the infant subject has access to an image of self. Lacan intimates that the mirror provides the frame through which one relates to others within the domain of vision, stressing the priority of narcissism and the ego over all other libidinal transactions. The Threshold of the Visible World provides a psychic, social and political specification of Lacan's claim, and most particularly of its implications for the subject's relations to the social other. This is accomplished through examination of the ego, as well as two other categories at the center of Lacan's account of the mirror stage: ideality and identification. This book is an ethical-political project which leads to the re-elaboration of a number of crucial theoretical categories--Silverman offers an account of the bodily ego, of identification, of idealization, of the gaze, of the look, and of the "photographic." The Threshold of the Visible World leads as well to the formulation of a fresh model for conceptualizing sexual, racial and class "difference," and the terms under which it might be dismantled. This book thus seeks to apprehend the field of vision through the frame of a different kind of bodily ego, and discover the pleasures to be derived from corporeal transport. (shrink)

Despite the prominence of thresholds in theories of distributive justice, there is no general account of what sort of role is played by the idea of a threshold within such theories. This has allowed an ongoing lack of clarity and misunderstanding around views that employ thresholds. In this article, I develop an account of the concept of thresholds in distributive justice. I argue that this concept contains three elements, which threshold views deploy when ranking possible distributions. These elements (...) are (i) the level of the threshold, (ii) what constitutes the value of the threshold, and (iii) how benefits above and below the threshold must be allocated. I highlight three contributions that this particular account of thresholds makes: it clarifies the nature of the shift that occurs at the threshold; it resolves a common misunderstanding about headcount principles; and it shows how the arbitrariness objection can be met.

Threshold- and signal-detection-based models have dominated theorizing about recognition memory. Building upon these theoretical frameworks, we have argued for a dual-process model in which conscious recollection and familiarity contribute to memory performance. In the current paper we assessed several memory models by examining the effects of levels of processing and the number of presentations on recognition memory receiver operating characteristics . In general, when the ROCs were plotted in probability space they exhibited an inverted U shape; however, when they (...) were plotted inzspace they exhibited a U shape. An examination of the ROCs showed that the dual-process model could account for the observed ROCs, but that models based solely on either threshold or signal-detection processes failed to provide a sufficient account of the data. Furthermore, an examination of subjects' introspective reports using the remember/know procedure showed that subjects were aware of recollection and familiarity and were able to consistently report on their occurrence. The remember/know data were used to accurately predict the shapes of the ROCs, and estimates of recollection and familiarity derived from the ROC data mirrored the subjective reports of these processes.

This article and associated short film, entitled Threshold, explores the phenomenon of house as a Cartesian construct of rational cultural detachment, set in binary opposition to the indigenous understanding of nature as connected and sacred. Threshold focuses on the liminal in-between zones of a house – its doors and windows – which both separate and join the inside/outside domains – without belonging to either of them. The film explores the liminal act of crossing this ontological threshold – (...) representing it cinematically as a vibrational, ocular/aural wavering between two ‘worlds’. The intention is to destabilize this duality on an emotional level – in order to interrogate its validity. This strategy references anthropological theory, which asserts that the liminal act stimulates the limbic system containing ancestral, instinctual deposits. The function of the limbic system (part of the triune brain model) accords with Jung’s theory of the collective unconscious – which views the house as an archetypal symbol, central to the meaning of dreams – in representing the psyche of the dreamer. Threshold attempts to invoke this and other archaic symbols as the camera journeys through its interior spaces, discovering its material culture artefacts, which reflect the psychic state of its inhabitants. The paper explores the indigenous belief that there is a mystical (unitive, transformative) relationship existing between space and acoustics that can only be fully appreciated through an emotional experience with it. The adoption of an arts interventionist approach, can, the article will argue, provide an important contribution towards our expanded understanding of Space and Place as an embodied, emotional-cognitive act.

I’ll describe a range of systems for nonmonotonic conditionals that behave like conditional probabilities above a threshold. The rules that govern each system are probabilistically sound in that each rule holds when the conditionals are interpreted as conditional probabilities above a threshold level specific to that system. The well-known preferential and rational consequence relations turn out to be special cases in which the threshold level is 1. I’ll describe systems that employ weaker rules appropriate to (...) thresholds lower than 1, and compare them to these two standard systems. (shrink)

Recent trends in psychiatry involve a transition from categorical to dimensional frameworks, in which the boundary between health and pathology is understood as a difference in degree rather than as a difference in kind. A major tenet of dimensional approaches is that no qualitative distinction can be made between health and pathology. As a consequence, these approaches tend to characterize such a threshold as pragmatic or conventional in nature. However, dimensional approaches to psychopathology raise several epistemological and ontological issues. (...) First, we review major sources of evidence usually recruited in support of the dimensional trend (focusing on clinical observation and biological data), and we show that these are connected to different conceptualizations of how dimensional traits extend across health and pathology. Second, we criticize two unquestioned assumptions that stand at the core of the dimensional trend: a) that there is continuity from health to pathology at the symptomatic level; b) that such continuity reflects an underlying continuity in the genetic liability for pathological conditions. Third, we argue against the idea of a conventional threshold by showing that such a view implies a linear relationship between the genotype and the phenotype. Fourth, drawing on epigenetics and developmental biology, we offer a characterization of mental disorders as stable and dynamic constellations of multi-level variables that differ qualitatively from ‘healthy states’. We conclude by showing that our account has several theoretical advantages over both categorical and dimensional approaches. Notably, it provides crucial insights into psychological development over time and individual differences, with major implications in terms of intervention and clinical decision-making. (shrink)

When research poses risks to non‐participant bystanders, it is not always practicable to obtain their consent. One approach to assessing how much research risk may be imposed on nonconsenting bystanders is to examine analogous circumstances, including risk thresholds deemed acceptable for nonconsenting research participants and for nonconsensual risks imposed outside the research setting. For nonconsenting participants, US research regulations typically limit risks to those deemed to be “minimal.” Outside the research context, US tort law tolerates a more flexible “reasonable” risk (...) threshold. This article advances a preliminary case that nonconsenting participants and nonconsenting bystanders exposed to similar research risks may be entitled to the same level of protection, but that risks generated by research may not be special in kind. Thus, limiting research risks to those that are “reasonable,” rather than demanding that they be held to the “minimal” standard, may be the best approach for both nonconsenting participants and nonconsenting bystanders. Further work is needed to establish whether the descriptive standards used to support the analogies relied on here are normatively justifiable, as well as the extent to which the minimal risk standard and the reasonable risk standard would lead to meaningfully different outcomes in practice.

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.

Based on the Lotka–Volterra system, a pest-natural enemy model with nonlinear feedback control as well as nonlinear action threshold is introduced. The model characterizes the implementation of comprehensive prevention and control measures when the pest density reaches the nonlinear action threshold level depending on the pest density and its change rate. The mortality rate of the pest is a saturation function that strictly depends on their density while the release of natural enemies is also a nonlinear pulse (...) term depending on the density of real-time natural enemies. The exact impulsive and phase sets are given. The definition and properties of the Poincaré map corresponding to the pulse points on the phase set are provided. We investigate the existence and stability of boundary and interior order-1 periodic solution. The theoretical analysis developed in the present paper combined with nonlinear controlling measures as well as nonlinear action threshold methods and techniques laid the foundation for the establishment and analysis of other state-dependent feedback control models.

Various types of plant species have been extensively used for heavy metals phyto-remediation without taking into consideration its tolerance threshold. In this study, Vetiver grass, Vetiveria zizanioides (Linn.) Nash was evaluated under five different sets of contaminated spiked cadmium (5Cd, 10Cd, 50Cd, 100Cd and 150Cd mg/kg) and lead (50Pb, 100Pb, 200Pb, 400Pb and 800Pb mg/kg) concentration levels in soil. The growth performance, metal tolerance and phyto-assessment of Cd and Pb in the roots and tillers were assessed using flame atomic (...) absorption spectrometry (FAAS). Tolerance index (TI), translocation factor (TF), biological transfer factor (BTF), biological accumulation coefficient (BAC) and metal uptake efficacy were used to determine the Cd and Pb translocation capability in Vetiver grass. Significantly higher (p<0.05) accumulation of Cd and Pb was recorded in the roots of all spiked treatments. Furthermore, strong and significantly positive correlations were exhibited between the increased levels of spiked heavy metal concentrations with both Cd (r=0.975) and Pb (r=0.952) accumulations. The results of this study showed Vetiver grass as an effective phyto-stabilizer for both Cd and Pb. Nevertheless, the growth of Vetiver grass was restricted when the tolerance threshold of 100 mg/kg (dry weight basis) Cd was exceeded in the contaminated soil. (shrink)

BackgroundOther Specified Feeding and Eating Disorders are characterized by less frequent symptoms or symptoms that do not meet full criteria for another eating disorder. Despite its high prevalence, limited research has examined differences in severity and treatment outcome among patients with OSFED compared to threshold EDs [Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder ]. The purpose of the current study was to examine differences in clinical presentation and treatment outcome between a heterogenous group of patients with OSFED or (...) threshold EDs.MethodPatients with threshold EDs or OSFED presenting for eating disorder treatment completed self-report questionnaires at intake and discharge to assess eating disorder symptoms, depression symptoms, impairment, and self-esteem.ResultsAt intake, OSFED patients showed lower eating concerns compared to patients with BN, but similar levels compared to AN and BED. The OSFED group showed higher restraint symptoms compared to BED, and similar restraint to AN and BN. Global symptoms as well as shape and weight concerns were similar between OSFED and threshold ED groups. There were no differences between diagnostic groups in self-esteem, depression scores, or symptom change from intake to discharge.DiscussionOur findings suggest that individuals with OSFED showed largely similar ED psychopathology and similar decreases in symptoms across treatment as individuals diagnosed with threshold EDs. Taken together, findings challenge the idea that OSFED is less severe and more resistant to treatment than threshold EDs. (shrink)

In philosophy, there is an as yet unresolved discussion on whether there are different kinds of kinds and what those kinds are. In particular, there is a distinction between indifferent kinds, which are unaffected by observation and representation, and interactive kinds, which respond to being studied in ways that alter the very kinds under study. This is in essence a discussion on ontologies and, I argue, more precisely about ontological levels. The discussion of kinds of kinds can be resolved by (...) using a semiotic approach to ontological levels, building on the key semiotic concept of representation. There are three, and only three, levels of semiosis: non- or proto-semiotic processes without representation, such as physical or causal processes; semiotic processes with representation, such as the processes of life and cognition; and second-order semiotic processes with representation of representation, such as self-awareness and self-reflexive communication. This leads to the distinction between not two, but three kinds of kinds: indifferent, adaptive and reflexive kinds, of which the last two hitherto have not been clearly distinguished. (shrink)

While genomic and proteomic information describe the overall cellular machinery available to an organism, the metabolic profile of an individual at a given time provides a canvas as to the current physiological state. Concentration levels of relevant metabolites vary under different conditions, in particular, in the presence or absence of different disorders. Metabolite concentrations thus mediate an important link between chemistry and biology, contributing to a systems-wide understanding of biological processes and pathways. However, there are a number of challenges in (...) the ontological representation of such information. Firstly, concentration information is numeric and ranges over continuous values, while ontologies consist of discrete classes. Secondly, ontologies usually model only what is certain, and their logical formalisms are adapted to reasoning from certain axioms to logical deductions, however, the link between chemicals and diseases via concentration levels, like many threshold phenomena, is both uncertain and vague. In this paper we evaluate the representation of this knowledge using a combination of concrete domains and probabilistic reasoning. We parse concentration values from HMDB and create an ontology able to distinguish normal from abnormal concentrations and able to evaluate a probabilistic risk category for the presence of an associated disorder.

This paper is about the ‘threshold problem’ for knowledge, namely, how do we determine what fixes the level of justification required for knowledge in a non-arbitrary way? One popular strategy for solving this problem is impurism, which is the view that the required level of justification is partly fixed by one’s practical reasoning situation. However, this strategy has been the target of several recent objections. My goal is to propose a new version of impurism that solves the (...) threshold problem without succumbing to these criticisms. (shrink)

Does a penny per month constitute a Basic Income? Were that penny to be paid individually, universally, and unconditionally, the answer would be ‘yes’, following the definition of Basic Income given by some of its leading advocates, be it organisations like the Basic Income Earth Network or prominent scholars such as Philippe Van Parijs. Some might be puzzled as to how this could be ‘a capitalist road to communism’, or give us ‘freedom as the power to say no’, both of (...) which have been advocated by prominent researchers. The purpose of this paper is not to argue for or against their definition, but rather to situate it historiographically, enabling fruitful discussion. The paper will show how there was a widely shared assumption in the 1970s and 80s, at the early stages of both academic articulations and public discussion, that Basic Income comes with some notion of a threshold or level to be taken as a minimum or as adequate. The paper goes on to outline three issues that arise once the concept of a threshold is dropped from the definition. Examined in addition are five justifications for doing so. Much like any other idea, the concept of Basic Income is a social construct. By situating it here within a historical perspective, we wish to facilitate academic discussion regarding both the achievements and erasures that have occurred as a consequence of the concept’s academic refinement—refinement that is in itself majorly indebted to BIEN and Van Parijs.

An item that stands out (is isolated) from its context is better remembered than an item consistent with the context. This isolation effect cannot be accounted for by increased attention, because it occurs when the isolated item is presented as the first item, or by impoverished memory of nonisolated items, because the isolated item is better remembered than a control list consisting of equally different items. The isolation effect is seldom experimentally or theoretically related to the primacy or the recency (...) effects—that is, the improved performance on the first few and last items, respectively, on the serial position curve. The primacy effect cannot easily be accounted for by rehearsal in short‐term memory because it occurs when rehearsal is eliminated. This article suggests that the primacy, the recency, and the isolation effects can be accounted for by experience‐dependent synaptic plasticity in neural cells. Neurological empirical data suggest that the threshold that determines whether cells will show long‐term potentiation (LTP) or long‐term depression (LTD) varies as a function of recent postsynaptic activity and that synaptic plasticity is bounded. By implementing an adaptive LTP‐LTD threshold in an artificial neural network, the various aspects of the isolation, the primacy, and the recency effects are accounted for, whereas none of these phenomena are accounted for if the threshold is constant. This theory suggests a possible link between the cognitive and the neurological levels. (shrink)

Joseph Conrad’s Heart of Darkness is a frequent point of reference for Edward Said’s investigations into the various forces that structure and define the encounter of imperial societies with others. In Culture and Imperialism, Said explains the importance of Conrad’s novella by linking it to his concept of culture as the aesthetic acme of a society that simultaneously marks it and divides it from others. In Heart of Darkness, Said claims, we have a narrative that challenges its own imperial society (...) by emphasizing the ambiguity of its cultural limit. Heart of Darkness is thereby able to dramatize and emphasize the constituent elements of imperial society, even as it is unable to exceed that society’s fundamental character. Said’s reading is important, and even vital, for an appreciation of the complexities of Conrad’s novella, but it does not go far enough. The ambiguity of Conrad’s depiction of imperial society is only an ambiguity to the extent that the novella is critiqued at the level of content, with a corresponding lack of emphasis upon its rhetorical form. Through a consideration of the three primary elements of this form – the careful situation of the Nellie as the site of the narrative, the work of interruption in Marlow’s narrative, and the reverberation of Kurtz’s dying words in the conclusion of the novella – this essay argues that there is very little ambiguity in Conrad’s text. Indeed, what ambiguity remains is a function of its effort to dramatize the limit of imperialism precisely as a limitation, as a cultural determinant that through its form perpetually determines other societies as inferior, even as this very culture, as a limit set against these other societies, shows their richness to which imperialism is essentially blind.

Collective memory is thought to be something “more” than a conglomeration of personal memories which compose it. Yet, each of us, each individual in every society, remembers from a personal point of view. And if there is memory beyond personal experience through which collective identities are configured, in what “place” might one legitimately situate it? In addressing this question, this article examines the political significance of the distinction between two levels of what are often lumped together under the term of (...) “collective memory”: memories that are retained through the direct experience of groups or associations of a limited size and those that are rarely the object of direct experience constituting the events marking the identities of mass societies.

In this paper, we apply the capabilities approach—with the addition of capability ceilings—to energy justice. We argue that, to ensure energy justice, energy policies and scenarios should consider enabling not only minimal capability thresholds but also maximum capability ceilings. It is permissible, perhaps even morally required, to limit the capabilities of those above the threshold if it is necessary for enabling those below the threshold to reach the level required by justice. We make a distinction between tragic (...) and non-tragic conflicts of capabilities: tragic conflicts are instances when one cannot raise an agent’s capabilities above the threshold that justice requires without pushing someone else below the threshold or restricting someone from reaching the threshold. In contrast, a non-tragic choice is when increasing someone above the threshold required by justice does not entail pushing someone else’s capabilities below the threshold. We utilise this framework to discuss energy justice and emissions of greenhouse gases. Drawing on the relation between points on the human development index and levels of energy consumption, we conclude that non-tragic mitigation policies now are highly preferable to tragic policies later.

This essay is a historical–geographical account of how scientists and public health officials conceptualized and assessed northern radioactive exposures in the late 1950s and 1960s. The detection of radionuclides in caribou bodies in northern Canada both demonstrated the global reach of nuclear fallout and revealed the unevenness of toxic relations and radioactive exposures. Following the documentation of the lichen–caribou–human pathway of exposure, Canadian public health officials became increasingly concerned about the possibility of heightened radioactive exposures among Indigenous northerners. Between 1963 (...) and 1969, scientists and officials with Canada’s Radiation Protection Division coordinated an interdepartmental monitoring program through which they sought to determine whether the consumption of contaminated caribou meat had caused radioactive exposure levels in northern communities to exceed the officially recognized “safe limits.” In 1969, the northern monitoring program was suspended after officials determined that radionuclide body burdens had not exceeded the threshold for radioactive exposures. While the RPD emphasized its development of a technoscientific approach to measuring radioactive body burdens, the legitimacy of the monitoring program was linked directly to interdepartmental relations within Canada’s colonial northern administration. I situate the northern monitoring program within broader shifts in public health approaches to radiation protection and use Gabrielle Hecht’s concept of nuclearity to demonstrate how RPD officials employed the logic of the threshold in their assessment of radioactive exposures.

This paper aims to shed light on the nature of belief and provide support to the view that I call ‘Minimalism’. It shows that Minimalism is better equipped than the traditional approach to separating belief from imagination and addressing cases of belief’s evidence- resistance. The key claim of the paper is that no matter how epistemically irrational humans’ beliefs are, they always retain a minimal level of rationality.

Purpose. The study is aimed at a philosophical analysis of the state of humanity’s readiness for technological singularity, the definition of the concept of postbiology and the investigation of ways to bring the population to a new, qualitatively higher level of existence. Theoretical basis. The author analyzes the level of public consciousness and the features of its cooperation with technological world. Due to the inability of most modern people to cope with changes effectively, the author questions humanity’s readiness (...) for the postbiological stage of evolution of our species. Based on the analysis of the ideas of authoritative futurists of our time, the author explores the prospects of Ukrainian society in the postbiological future. Originality. The author not only analyzes the challenges that humanity faces during its transition to a new type of civilization, but also explores the obstacles that hinder this process directly in the Ukrainian society. The author proves that the ideas of transhumanism and going beyond the human biology should not be postulated without a moral context. In addition, the scientific study proposes a number of projects designed to improve the educational institutions that are responsible for the intellectual and spiritual development of the individual. Conclusions. Postbiology can become both, a new qualitatively higher stage of the human species evolution and the collapse of humaneness. Along with overcoming human biology, there will be the destruction of moral guidelines, social and legal systems. In order to prevent total chaos and catastrophe, technological development must be complemented by appropriate developments of new norms that can balance society. (shrink)

A key working hypothesis in neuroscience is ‘materialistic reductionism’, i.e., the assumption whereby all physiological, behavioral or cognitive phenomena is produced by localized neurochemical brain activation (but not vice versa). However, analysis of sub-threshold Weber’s psychophysical stimulation indicates its computational irreducibility to the direct interaction between psychophysical stimulation and any neuron/s. This is because the materialistic-reductionistic working hypothesis assumes that the determination of the existence or non-existence of any psychophysical stimulation [s] may only be determined through its direct interaction (...) [di1] with a given neuron/s [N] that together forms the ‘neural registry’ computational level [NR/di1]. But, this implies that in cases of (initial) sub-threshold (sensory-specific) psychophysical stimulation which is increased above the sensory-specific threshold but below Weber’s psychophysical ‘dv’—the psychophysical computational processing [PCP] produces an apparently ‘computationally indeterminate’ output. This is because materialistic reductionism asserts the contingency of PCP upon the existence of a direct interaction between ‘s’ and ‘N’ within the NR/di1 level, but in the special case of Weber’s sub-threshold psychophysical stimulation the same PCP/di1 also asserts the non-existence of ‘s’ (as demanded by Weber’s psychophysical law). However, given robust empirical evidence indicating the capability of PCP to determine whether (or not) ‘s’ exists, we must conclude that PCP may not be carried out from within NR’s direct interaction between a particular psychophysical stimulation and any set of neuron/s in the brain. Hence, the Duality Principle asserts the conceptual irreducibility of sub-threshold psychophysical stimulation to any direct NR/di1: s-N interaction, thereby challenging the current materialistic-reductionistic assumption.

Multi-level institutional designs with distributed power and authority arrangements among federal, state, regional, and local government agencies could lead to the emergence of differential patterns of socioeconomic and infrastructure development pathways in complex social–ecological systems. Both exogenous drivers and endogenous processes in social–ecological systems can lead to changes in the number of “basins of attraction,” changes in the positions of the basins within the state space, and changes in the positions of the thresholds between basins. In an effort to (...) advance the theory and practice of the governance of policy systems, this study addresses a narrower empirical question: how do intergovernmental institutional rules set by federal, state, and regional government agencies generate and sustain basins of attraction in funding infrastructure projects? A pattern-oriented, agent-based model (ABM) of an intergovernmental network has been developed to simulate real-world transportation policy implementation processes across the federal, the state of Vermont, regional, and local governments for prioritizing transportation projects. The ABM simulates baseline and alternative intergovernmental institutional rule structures and assesses their impacts on financial investment flows. The ABM was calibrated with data from multiple focus groups, individual interviews, and analysis of federal, state, and regional scale transportation projects and programs. The results from experimental simulations are presented to test system-wide effects of alternative multi-level institutional designs, in particular different power and authority arrangements between state and regional governments, on the emergence of roadway project prioritization patterns and funding allocations across regions and towns.

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 21.1 (2001) 144-147 [Access article in PDF] Book Review Welcoming Flowers from Across the Cleansed Threshold of Hope: An Answer to the Pope's Criticism of Buddhism Welcoming Flowers from Across the Cleansed Threshold of Hope: An Answer to the Pope's Criticism of Buddhism. By Thinley Norbu. New York: Jewel Publishing House, 1997. 93 pp. Welcoming Flowers is a short and tightly written critique of the (...) Buddhism chapter of Pope John Paul II's 1994 best-seller, Crossing the Threshold of Hope. It is a strong, barbed, personal essay from a highly respected Buddhist teacher who expresses shock and dismay that the Pope's actual words about Buddhism that are read as absolute truth by millions of people around the world had "serious, gratuitous misrepresentations of Buddhist doctrine."The book is ostensibly a response to requests from Polish readers and a Polish publishing company to comment on "what the Pope clearly said about Buddhism." The author of Welcoming Flowers, Thinley Norbu, paints himself as a kind of efficient, spiritual cleaning maid who, with tongue in cheek despite his long admiration for the Catholic leader, has to tidy up after the Vicar of Rome: "It is as though the Pope suddenly vomited insolently and uncontrollably in a cathedral, so I hastily had to clean it up, as the Polish people asked me to do."The Pope's negative assessment of Buddhism inspired Thinley Norbu to match [End Page 144] his attack with even more exalted teachings of the Buddha: "I am grateful to the Pope for being like a hit-hitting drumstick that has given me the good opportunity to be like a drum myself, resonating with the sound of profound Dharma. I am grateful to the Pope for yelling with negative words in a valley, letting me return the answer of its transformation into the positive echo of Buddhist hymns."Thinley Norbu in fact uses the Pope's chapter to clarify some basic teachings of Vajrayana Buddhism and how it differs from Mahayana and Hinayana (note: Norbu's term, not this reviewer's) in a concise and instructive manner from the point of view of a practitioner. In this regard,Welcoming Flowers can be considered a kind of introductory, primary source ofTibetan (Nyingma)Vajrayana Buddhist doctrine for those who are unfamiliar with the various schools of Buddhism. The Pope's seriously outdated (reminiscent of Max Weber or early missionaries), limited, and unsympathetic understanding of one school of Buddhism is used by Thinley Norbu as a platform to expound his rich understanding of Buddhist traditions toWestern readers of comparative religion and specifically to Catholics. The book's twenty-nine footnotes can also function as a brief glossary of transliterated TibetanVajrayana Buddhist terms (but without use of diacritical marks for Sanskrit or Pali terms).Thinley Norbu is careful to mitigate his condemnation of the Pope's unwarranted ignorance of Buddhism by sharing the onus with the Pope's not-so-sapient preceptors. He generously suggests that the Pope may not bear all the blame for the chapter's shortcomings in the following paragraph: The misrepresentations of Buddhism in his book may have come from listening to advisors who were unfamiliar with Buddhism, from simply glancing at books at the Hinayana level, or by being shown books by misinformed authors. Perhaps he only looked at negative conceptions about Buddhism written by followers of other doctrines who had malicious intentions, or by idiots who wrote books for money without caring that they were full of mistakes. In any case, the Pope definitely heard about Buddhism from sources that did not know anything about it. It seems... as though he... scooped a few drops of water from an immeasurable ocean with a piece of grass and even misunderstood these few drops (p. 2). Norbu reprimands the Pope for not doing his required homework, a fault that can lead to serious disharmony among religions."Without studying and understanding other doctrines deeply, to say many things about them is not wise," Norbu continues; "it...

The present article discusses various suggestions for a philosophical framework for a transdisciplinary information science or a semiotic doctrine. These are: the mechanical materialistic, the pan-informational, the Luhmanian second order cybernetic approach, Peircian biosemiotics and finally the pan-semiotic approach. The limitations of each are analyzed. The conclusion is that we will not have to choose between either a cybernetic-informational or a semiotic approach. A combination of a Peircian-based biosemiotics with autopoiesis theory, second order cybernetics and information science is suggested in (...) a five-leveled cybersemiotic framework. The five levels are 1) a level of Firstness, 2) a level of mechanical matter, energy and force as Secondness, 3) a cybernetic and thermodynamic level of information and signal, 4) a level of sign games in living systems, and 5) a level of conscious language games in self-conscious social humans.

The aim of this study was to verify the importance of reinforcing a sex stereotype onparticipants’ identification with this role. The results were analysed as a function of both biological sex and psychological gender. In the study the Psychological Gender Inventory was used, as well as a scale measuring Agency and Communion, a scale measuring Unmitigated Agency and Unmitigated Communion, lists of sentences containing stereotypes of the male sex and the female sex, and sentences that were neutral with regard to (...) sex. The results showed that feminine women ascribed more female characteristics to themselves regardless of whether the role that was associated with their biological sex was reinforced or not. Men showing characteristics of both sexes ascribed a similar level of unmitigated communion and agency to themselves irrespective of whether the sex stereotype was reinforced or not. (shrink)

One prominent welfarist axiology, critical-level utilitarianism, says that individual lives must surpass a specified ‘critical level’ in order to make a positive contribution to the comparative status of a given population. In this article I develop a new dilemma for critical-level utilitarians. When comparatively evaluating populations composed of different species, critical-level utilitarians must decide whether the critical level is a universal threshold or whether the critical level is a species-relative threshold. I argue (...) that both thresholds lead to a range of axiological puzzles and objections as yet undiscussed within the literature, and therefore conclude that critical-level utilitarianism should not be taken as a morally plausible welfarist axiology. I show that certain competitive formulations of critical range utilitarianism are subject to the argument too, and that further attempts to relativise critical levels to a particular group or category of welfare bearer are unsustainable.

. This paper presents a new approach to segment low quality fingerprint images which are collected by low quality fingerprint readers. Images collected using such readers are easy to collect but difficult to segment. The proposed approach is based on combining global and local processing to achieve segmentation of fingerprint images. On the global level, the fingerprint is located and extracted from the rest of the image by using a global thresholding followed by dilation and edge detection of the (...) largest object in the image. On the local level, fingerprint's foreground and its border image are treated using different fuzzy rules. These rules are based on the mean and variance of the block under consideration. The approach is implemented in three stages: pre-processing, segmentation, and post-processing. Segmentation of 100 images was performed and compared with manual examinations by human experts. The experiments showed that 96% of images under test are correctly segmented. The results from the quality of segmentation test revealed that the average error in block segmentation was 2.84% and the false positive and false negatives were approximately 1.4%. This indicates the high robustness of the proposed approach. (shrink)

Light increment thresholds were measured on either side of one of the illusory contours of a white-on-black Kanizsa square and on the illusory contour itself. The data show that thresholds are elevated when measured on either side of the illusory border. These elevations diminish with increasing distance of the target spot from the white elements which induce the illusory figure. The most striking result, however, is that threshold elevations are considerably lower or even absent when the target is located (...) on the illusory contour itself. At an equivalent position in a control figure where no illusory contour is visible, such a threshold decrease does not occur. The present observations add empirical support to neural theories of illusory form perception. (shrink)

Pakistan’s evolution into a research-centric nation, recognized by Clarivate Analytics, suggests a transition towards a knowledge-based economy. However, the prevalence of academic dishonesty within Pakistan’s academic institutions raises concerns, potentially impeding the realization of its intellectual prowess. This research therefore examines the drivers of academic dishonesty in Pakistani universities, drawing on data collected from 457 students in four prominent public sector universities. Regression analysis of the dataset reveals several noteworthy findings. The study identifies that male gender, larger family size, risk (...) preference, anxiety, and susceptibility to peer influence correlate positively with academic dishonesty. Conversely, students’ socio-economic status and their perception of diminished respect for dishonest behavior act as deterrents. Furthermore, the impact of detection on academic dishonesty exhibits a threshold effect, while personal integrity/morality and punitive measures appear to have limited impact on academic dishonesty. Consequently, this study underscores the importance of addressing socio-cultural and environmental factors as pivotal elements in combating unethical academic conduct within Pakistan. (shrink)

People often think there are moral duties that hold irrespective of the consequences, until those consequences exceed some threshold level – that we shouldn’t kill innocent people in order to produce the best consequences, for example, except when those consequences involve saving millions of lives. This view is known as “threshold deontology.” While clearly controversial, threshold deontology has significant appeal. But it has proven quite difficult to provide a non-ad hoc justification for it. This chapter develops (...) a new justification, showing that acting like a threshold deontologist is a good strategy for being moral, given our uncertainty and imperfect moral knowledge. And failing to use good strategies for being moral is, itself, morally bad. (shrink)

This study investigates the engagement of family firms in corporate social responsibility. We first compare their corporate social performance to non-family firms. Then, following recent evidence on the heterogeneity of family firms, we examine two factors that may influence CSP within family firms: the level of family control and the governance orientation of the country in which they operate. This research is based on a theoretical framework which considers both agency and socioemotional wealth influences on family firms CSR engagements. (...) Overall, we find that family firms exhibit lower CSP than non-family firms. But when focusing on family firms, our analyses show a curvilinear relationship between family control and CSP. At lower levels of control, family owners invest more in social initiatives to protect their SEW. Beyond a threshold level of control that we estimate at 36 % in our sample, economic considerations prevail over SEW and social performance starts decreasing. We also find that family firms operating in stakeholder-oriented countries are more attentive to social concerns than those operating in more shareholder-oriented countries. (shrink)

A capability approach prescribes paternalist government actions to the extent that it requires the promotion of specific functionings, instead of the corresponding capabilities. Capability theorists have argued that their theories do not have much of these paternalist implications, since promoting capabilities will be the rule, promoting functionings the exception. This paper critically surveys that claim. From a close investigation of Nussbaum's statements about these exceptions, it derives a framework of five categories of functionings promotion that are more or less unavoidable (...) in a capability theory. It argues that some of these categories may have an expansionary dynamic; they may give rise to widespread functionings promotion, which would defeat the capabilitarian promise that paternalist interventions will be exceptions to the rule of a focus on capabilities. Finally, the paper discusses three further theoretical issues that will be decisive in holding this paternalist tendency in check: how high one sets threshold levels of capability protection, how lengthy one's list of basic capabilities is, and how one deals with individual responsibility for choices resulting in a loss of one's capabilities.

A hypothesis on the physiological conditions for the occurrence of phenomenal states is presented. It is suggested that the presence of phenomenal states depends on the rate at which neural assemblies are formed. Unconsciousness and various disturbances of phenomenal consciousness occur if the assembly formation rate is below a certain threshold level; if this level is surpassed, phenomenal states necessarily result. A critical production rate of neural assemblies is the necessary and sufficient condition for the occurrence of (...) phenomenal states. (shrink)

This article shows that judicial review has a democratic justification even though judges may be no better at protecting rights than legislatures. That justification is procedural, not consequentialist: reflecting the ability of judicial review to express and protect citizen’s interests in political participation, political equality, political representation and political accountability. The point of judicial review is to symbolize and give expression to the authority of citizens over their governors, not to reflect the wisdom, trustworthiness or competence of judges and legislators. (...) Above a threshold level of competence – which may be impossible to determine a-priori – the legitimacy of judicial review does not turn on the special wisdom, virtue or personal qualities of judges. Instead, it reflects the importance that democracies properly attach to the ordinary virtues and competences of individuals in justifying power and authority. Hence, this article takes issue with the defence of judicial review in Eisgruber and Brettschneider, as well as with the critiques of judicial review found in Waldron and Bellamy. (shrink)

In the present study, we have demonstrated hysteresis phenomena in the excitability of single, enzymatically dissociated guinea pig ventricular myocytes. Membrane potentials were recorded with patch pipettes in the whole-cell current clamp configuration. Repetitive stimulation with depolarizing current pulses of constant cycle length and duration but varying strength led to predictable excitation (1:l) and non-excitation (1:0) patterns depending on current strength. In addition, transition between patterns depended on the direction of current intensity change and stable hysteresis loops were obtained in (...) stimulus:response pattern vs. current intensity plots in 14 cells. Increase of pulse duration and decrease of stimulation rate contributed to a reduction in hysteresis loop areas. Changes in amplitude and shape of the subthreshold responses during the transitions from one stable pattern to the other, suggested that activity led to an increase in membrane resistance, particularly in the voltage domain between resting potential, and threshold. Therefore, we modelled the dynamic behaviour of the single cells as a function of diastolic membrane resistance, using previously published analytical solutions. Numerical iteration of the analytical model equations closely reproduced the experimental hysteresis loops in both qualitative and quantitative ways. In particular, the effect of stimulation frequency on the model was similar to the experimental findings. The overall study suggests that the excitability pattern of guinea pig ventricular myocytes accounts for hysteresis and bistabilities when current intensity is allowed to fluctuate around threshold levels.

Telic sufficientarians hold that there is something special about a certain threshold level such that benefiting people below it, or raising them above it, makes an outcome better in at least one respect. The article investigates what fundamental value might ground that view. The aim is to demonstrate that sufficientarianism, at least on this telic version, is groundless and as such indefensible. The argument is advanced in three steps: first, it is shown that sufficientarianism cannot be grounded in (...) a personal value. Neither, secondly, is it committed to the person-affecting view, the view that says that nothing can be better if there is no one for whom it is better. This, in itself, is of interest because some sufficientarians reject egalitarianism precisely for its alleged incompatibility with the person-affecting view. Sufficientarians' disavowal of the person-affecting view implies that their view, similarly to egalitarianism, must be anchored in some impersonal value. But crucially, and this is the third step of the argument, there is no apparent value that can fit that role. We must conclude, then, that telic sufficientarianism is groundless. (shrink)

In a penetrating investigation of the relationship between belief and quantitative degrees of confidence (or degrees of belief) Richard Foley (1992) suggests the following thesis: ... it is epistemically rational for us to believe a proposition just in case it is epistemically rational for us to have a sufficiently high degree of confidence in it, sufficiently high to make our attitude towards it one of belief. Foley goes on to suggest that rational belief may be just rational degree of confidence (...) above some threshold level that the agent deems sufficient for belief. He finds hints of this view in Locke’s discussion of probability and degrees of assent, so he calls it the Lockean Thesis.1 The Lockean Thesis has important implications for the logic of belief. Most prominently, it implies that even a logically ideal agent whose degrees of confidence satisfy the axioms of probability theory may quite rationally believe each of a large body of propositions that are jointly inconsistent. For example, an agent may legitimately believe that on each given occasion her well-maintained car will start, but nevertheless believe that she will eventually encounter a.. (shrink)

The strong correlation between people’s socioeconomic position and health within high income countries is a well-documented fact. A person’s occupation, income and education level tell us a lot about that person’s prospects on a long and healthy life, such that we can speak of a ‘social gradient in health’, or a ‘socioeconomic health gap’. This association is often perceived to be unjust. Therefore, it is generally thought that governments should aim to reduce socioeconomic health inequalities. However, this idea needs (...) ethical justification, for it is not evident if and why exactly these inequalities are unjust. For instance, are inequalities in health unjust per se? Or because the underlying socioeconomic inequalities are unjust? And does justice require equal health levels, or a minimum level of health? What complicates the issue, is that the width of the health gap, or the steepness of the social gradient, depends on what health measures are used. Overall, the more subjective the measure, the greater the inequalities appear to be. But are all these measures equally morally relevant? This dissertation aims to give a better understanding of these philosophical questions. It does so by investigating the question of what we should understand by health in the first part, after which it addresses the question of how to evaluate socioeconomic health inequalities in the light of justice. The introduction begins with a description of the phenomenon of socioeconomic health inequalities, and how it has been addressed by politicians, epidemiologists and philosophers in the past and today. The chapter continues by formulating the central question of the dissertation – that of which health inequalities should be focused in the light of a concern with social justice. It explicates how this dissertation contributes to answering that question, by discussing the potential relation between the conceptualisation of health and justice evaluations, and by discussing which questions are addressed in each of the following chapters. The chapter 2 addresses the question of how health is conceptualised in the philosophical and public heath literature, and how theoretical concepts of health differ. It proposes to approach health concepts as a Wittgensteinian family of thick concepts and argues that while theories on health generally argue in favour of one specific concept, a comparison of concepts shows that we may need different concepts of health given the variety of health practices. By explicating the differences between five concepts of health, this chapter argues that each captures aspects of health that all seem relevant when we talk and think about health. Classifying these concepts based on their distinctions reveals them as members of a conceptual family: each of the discussed concepts differs from the others in at least one respect and resembles the others in several respects. Moreover, the discussion of the concepts shows that ‘health’ always both describes a condition and values that condition at the same time. Having both descriptive and evaluative dimensions, we can see health concepts as ‘thick concepts’. Given this evaluative dimension, it is important to reflect on the question of what understanding of health guides specific practices. Moreover, the distinctions revealed by the classification can serve as a conceptual toolbox for reflection on the assumptions and purposes of health practices. How such reflection could work is illustrated by a brief exploration of what health aspects are focused upon in three specific health practices. Chapter 3 presents a study into the question of how health is conceptualised by ordinary citizens and to what extent conceptualisations of health differ between socioeconomic groups. By making use of the method of concept mapping, this study analyses how different socioeconomic groups formulate their own answers regarding the question ‘what does health mean to you?’. It presents concept maps of health for three different socioeconomic groups living in the city of Utrecht that reveal that all groups have a multidimensional understanding of health. An interpretation of the concept maps reveals nuanced differences between groups. The multiple aspects of health were also ranked by importance. It appears that each group assigned most importance to mental health. All in all, the study shows that people in lower socioeconomic groups are more likely to show a conceptualisation of health that refers to 1) the absence of health threats, 2) a person within his/her circumstances, 3) the value of functional notions, and 4) an accepting attitude towards life. Chapter 4 addresses the question of what the theoretical and empirical study to concepts of health could imply for health equity practices. It does so by exploring further the suggestions made in chapters 2 and 3. Regarding the question of which health aspects should guide health equity policies, this chapter discusses the question of whether we should primarily look at subjective or objective health measures, and whether a universal or relative standard of health should be central. While justice-related concerns of impartiality and equal treatment may seem to favour an objective perspective and a universal health standard, it appears that we have good reason to account for the subjective perspective as well. It is also argued that a concern for recognition and participatory parity gives room for relative health standards. Th room for relative health standards confronts us with the question of how to deal with mechanisms like adaptive preferences that the concept maps reveal. It proposes a way out, by arguing for society-relative health standards. Chapter 5 examines the question of whether inequalities in health should be evaluated ‘directly’, thus independently of a distribution of their social determinants. It proposes a sufficientarian perspective, such that the central question of evaluation is that of whether everyone is – or can be – healthy enough. By discussing two sufficientarian approaches to health and social justice – by Powers & Faden and by Nussbaum – this chapter distinguishes two ways of setting a threshold level for health. Both approaches appear to provide an unsatisfactory basis for justice evaluations and lead us away from direct evaluation if we try to settle health minima that are less arbitrary. In anticipation to chapters 6 and 7, it is argued that the perspective of sufficient health for relational equality escapes this arbitrariness: compared to that of a decent human life, it better helps to answer both the question of what socioeconomic health inequalities a society is due to avoid, and the question of when socioeconomic health inequalities are unjust considering their consequences. Chapter 6 discusses to what extent Daniels’s theory of health justice provides a satisfactory answer to the question of what health inequalities a society is due to avoid. Daniels proposes an indirect evaluative approach by arguing that we should evaluate socioeconomic health inequalities in the light of Rawls’s principles of justice as fairness. That is, if socioeconomic inequalities are in accordance with fair equality of opportunity and with the difference principle, the corresponding health inequalities would be just. It is shown that the suggestion that Rawls’s principles regulate the social determinants of health neglects that not all social determinants of health belong to society’s basic structure as conceived of by Rawls and are thereby not subjected to the principles of justice. To acknowledge the social mechanisms leading to socioeconomic health inequalities in their full complexity, it is argued that we should broaden our understanding of society’s structure in accordance with Young’s notion of social structural processes. This renders the question of what health inequalities a society is due to avoid into a question of what we can expect from the side of the various actors that uphold the social structures that produce socioeconomic health inequalities. Lastly, it is discussed how a shift to Young’s theory completes the shift to non-ideal theorising that seem already initiated by Daniels, and that with this, the distinction between direct and indirect evaluation dissolves. Chapter 7 discusses to what extent equality in health is of instrumental value for a society of free and equals. It thus takes up the idea proposed in chapter 5, that an evaluation of the consequences of health inequalities is also due. Taking relational equality as an evaluative framework reveals three ways in which inequalities in life expectancy threaten this ideal. That is, via unequal risks to stigmatisation, unequal risks to unemployment and the risk of unequal pension enjoyments. It is thereby shown that these risks are especially great for those lower down the socioeconomic strata. It thus concludes that equality in health is of instrumental value to relational equality. The chapter continues to argue that our instrumental approach opens a new perspective: to mitigate the identified injustices by changing society, rather than by reducing inequalities in health. This is argued to be an advantage in the light of the realistic assumption that of the socioeconomic health inequalities will persist. The paper thus offers a complementary approach to both the evaluation and the mitigation of the injustice of socioeconomic inequalities in health. The discussion chapter summarises the central findings of the analyses of health concepts and discusses questions regarding the philosophical and practical merits of comparing theoretical health concepts, the need for developing new health measures or concepts and the importance or nonsense of studying citizen’s views on health. Repeating this for the dissertation’s second part, the central findings of the chapters on justice evaluation are summarised and followed by a discussion of questions and issues that have remained unaddressed so far. Here, central points of discussion are my take on rules of distribution, the distinction of direct and indirect evaluation, the role of ideal and non-ideal theory, the idea of relational equality, and personal responsibility for health. The chapter concludes by noting that also in the light of justice evaluations, all commonly used health measures are relevant for justice. Therefore, my recommendations for policy and further research entail that inequalities in each of these measures deserve attention by both policymakers and researchers. Specifically, policymakers and researchers should give attention to how exactly each of these health inequalities come about, in such a way that a discussion about the question of who can be assigned responsibility to alleviate them is well-informed; and both should give attention to the effects of health inequalities on the opportunities for people to live on equal standing, in such a way that when these opportunities are diminished, actions can be considered to aim to restore relational equality.

Growing demand for direct care workers to assist care-dependent elderly people has created an opening for migrant workers from low- income nations to sell their services to middle and high-income nations. Using Singapore as a case example, we draw on capability theory to make the case that receiving nations that import direct care workers should be held to global justice standards that protect workers’ floor level human capabilities. Specifically, we (1) show that Singapore and other receiving nations fail to (...) protect human capabilities at a threshold level required by dignity; (2) identify specific human capabilities placed at risk; and (3) recommend standards for receiving nations that support central capabilities. As populations in both developed and developing nations are rapidly aging, these concerns could not be timelier. (shrink)
