This unique volume explores what ethics has to offer the practicing physician, nurse, and allied health care worker. The authors introduce the basic vocabulary of ethics and present and discuss the most commonly used ethical theories, using case studies to illustrate how ethics work within the context of health care. Newcomers to the field will learn what ethics is all about and how it relates to the pragmatic concerns of the health care professional. Those who already have a working knowledge (...) of the field will find a new approach to ethical theory--personalism--which the authors believe can make the practical use of ethics more effective and reliable.

According to Alvin Goldman, reliabilists need to distinguish between unconditionally and conditionally reliable processes. The latter category is used to account for processes such as reasoning or memory. In this paper, I will argue that Goldman’s account of conditional reliability needs substantial revision in two respects. First, conditional reliability must be reinterpreted in terms of dependent reliability to avoid serious problems. Second, we need a more liberal account that allows dependently reliable processes to operate not only (...) on doxastic but also on non-doxastic input. Thinking this way advances the explanatory power of reliabilism significantly. (shrink)

Rumors, for better or worse, are an important element of public discourse. The present paper focuses on rumors as an epistemic phenomenon rather than as a social or political problem. In particular, it investigates the relation between the mode of transmission and the reliability, if any, of rumors as a source of knowledge. It does so by comparing rumor with two forms of epistemic dependence that have recently received attention in the philosophical literature: our dependence on the testimony of (...) others, and our dependence on what has been called the ‘coverage-reliability’ of our social environment (Goldberg 2010). According to the latter, an environment is ‘coverage-reliable’ if, across a wide range of beliefs and given certain conditions, it supports the following conditional: If ~p were true I would have heard about it by now. However, in information-deprived social environments with little coverage-reliability, rumors may transmit information that could not otherwise be had. This suggests that a trade-off exists between levels of trust in the coverage-reliability of official sources and (warranted) trust in rumor as a source of information. (shrink)

It is a widely shared view among philosophers of science that the theory-dependence (or theory-ladenness) of observations is worrying, because it can bias empirical tests in favour of the tested theories. These doubts are taken to be dispelled if an observation is influenced by a theory independent of the tested theory and thus circularity is avoided, while (partially) circular tests are taken to require special attention. Contrary to this consensus, it is argued that the epistemic value of theory-dependent tests (...) has nothing to do with the circularity or non-circularity of the test, but is instead based on the minimal empiricality and reliability of observations. Since theory-dependence does not in general prevent observations fulfilling these requirements, it should not be regarded as a phenomenon that is basically detrimental, but as neutral with respect to successful scientific knowledge gathering.

It is a live possibility that certain of our experiences reliably misrepresent the world around us. I argue that tracking theories of mental representation have difficulty allowing for this possibility, and that this is a major consideration against them.

Why believe in the findings of science? John Ziman argues that scientific knowledge is not uniformly reliable, but rather like a map representing a country we cannot visit. He shows how science has many elements, including alongside its experiments and formulae the language and logic, patterns and preconceptions, facts and fantasies used to illustrate and express its findings. These elements are variously combined by scientists in their explanations of the material world as it lies outside our everyday experience. John Ziman’s (...) book offers at once a valuably clear account and a radically challenging investigation of the credibility of scientific knowledge, searching widely across a range of disciplines for evidence about the perceptions, paradigms and analogies on which all our understanding depends.

Advanced medical imaging, such as CT, fMRI and PET, has undergone enormous progress in recent years, both in accuracy and utilization. Such techniques often bring with them an illusion of immediacy, the idea that the body and its diseases can be directly inspected. In this paper we target this illusion and address the issue of the reliability of advanced imaging tests as knowledge procedures, taking positron emission tomography in oncology as paradigmatic case study. After individuating a suitable notion of (...) reliability, we argue that PET is a highly theory-laden and non-immediate knowledge procedure, in spite of the photographic-like quality of the images it delivers; the diagnostic conclusions based on the interpretation of PET images are population-dependent; PET images require interpretation, which is inherently observer-dependent and therefore variable. We conclude with a three-step methodological proposal for enhancing the reliability of advanced medical imaging. (shrink)

In recent years, the epistemic reliability of moral intuitions has been undermined by substantial empirical data reporting the influence of cognitive biases. This paper discusses and elaborates upon a promising strategy in response to the reliability challenge to moral intuitions. The argument considered appeals to the fact that moral intuitions come in different levels of strength and agents accept only strong intuitions, not vulnerable to bias under realistic circumstances. This essay aims to reconstruct the defense from the (...) class='Hi'>reliability challenge in its most promising form and to evaluate the plausibility of the argument in light of the available empirical evidence. What will emerge from the discussion is that the vindication of moral intuitions fundamentally depends on two distinct premises: first, the hypothesis that agents accept moral intuitions proportionally to their level of confidence, and second, the hypothesis that intuitive confidence is epistemically reliable. Whereas there is consistent evidence for the first hypothesis, there is still no conclusive evidence for the second. (shrink)

The “problem of memory” in epistemology is concerned with whether and how we could have knowledge, or at least justification, for trusting our apparent memories. I defend an inductive solution—more precisely, an abductive solution—to the problem. A natural worry is that any such solution would be circular, for it would have to depend on memory. I argue that belief in the reliability of memory can be justified from the armchair, without relying on memory. The justification is, roughly, that my (...) having the sort of experience that my apparent memory should lead me to expect is best explained by the hypothesis that my memories are reliable. My solution is inspired by Harrod’s (1942) inductive solution. Coburn (1960) argued that Harrod’s solution contains a fatal flaw. I show that my solution is not vulnerable to Coburn’s objection, and respond to a number of other, recent and likely objections. (shrink)

I argue that beliefs that are true whenever held-like I exist, I am thinking about myself, and (in an object-dependent framework) Jack = Jack-needn't on that account be a priori. It does however seem possible to remove the existential commitment from the last example, to get a belief that is knowable a priori. I discuss some difficulties concerning how to do that.

Reliability and external validity are two fundamental values that pose incompatible constraints on neurobiological experiments. The more reliability an experimental result achieves, the less external validity it earns, and vice versa. In this article, I propose an externalist interpretation of external validity: the external validity of an experimental result depends not only on how much complexity is built into an experimental design, but also on the relationship between the experimental result and other related experiments. This externalist interpretation, which (...) explains how a neurobiological experiment can be reliable and externally valid simultaneously, suggests a new way to understand the epistemology of neurobiological experimentation.

Scientific measurements are made objective through the use of reliable instruments. Instruments can have this function because they can - as material objects - be investigated independently of the specific measurements at hand. However, their materiality appears to be crucial for the assessment of their reliability. The usual strategies to investigate an instrument’s reliability depend on and assume possibilities of control, and control is usually specified in terms of materiality of the instrument and environment. The aim of this (...) paper is to investigate the problem of reliability for non-material instruments, the instruments being applied in the social sciences. Any possible lack of reliability of the instrument hinders the measurements of ever becoming objective. (shrink)

: Evidence claims depend on fallible assumptions. Three strategies for making true evidence claims in spite of this fallibility are strengthening the support for those assumptions, weakening conclusions, and using multiple independent tests to produce robust evidence. Reliability itself, understood in frequentist terms, does not explain the usefulness of all three strategies; robustness, in particular, sometimes functions in a way that is not well-characterized in terms of reliability. I argue that, in addition to reliability, the security of (...) evidence claims is of epistemic value, where an evidence claim is secure relative to an epistemic situation if it remains true in all scenarios that are epistemically possible relative to that epistemic situation.

Indeterminacy in dating and elusive modes of intertextuality often confound attempts to establish reliable relative chronologies for classical South Asian texts. Occasionally, however, the relationship between two texts clearly reveals the dependence of one upon the other. Such is the case for the Arthaśāstra of Kauṭilya and the Mānava Dharmaśāstra, arguably the two most important classical treaties on law and statecraft. Close reading of the two reveals a direct relationship wherein the seventh adhyāya of the Mānava Dharmaśāstra took its general (...) structure and most of its material from the Arthaśāstra.The clarification of this general relationship makes possible an appreciation of the manner in which Manu appropriated material from Kauṭilya’s treatise and allows us to draw new conclusions and raise new questions about the intellectual and cultural history of the period.

Recent research introduced the Discounting Inventory that allows the measurement of individual differences in the delay, probabilistic, effort, and social discounting rates. The goal of this investigation was to determine several aspects of the reliability of the Discounting Inventory using the responses of 385 participants. Two types of reliability are of interest. Internal consistency and test-retest stability. A secondary aim was to extend such reliability measures beyond the non-clinical participant. The current study aimed to measure the (...) class='Hi'>reliability of the DI in a nicotine-dependent individuals and non-nicotine-dependent individuals. It is concluded that the internal consistency of the DI is excellent, and that the test-retest reliability results suggest that items intended to measure three types of discounting were likely testing trait, rather than state, factors, regardless of whether “non-smokers” were included in, or excluded from, the analyses. With these cautions in mind, however, the psychometric properties of the DI appear to be very good. (shrink)

This paper disputes the widely held view that one cannot establish the reliability of a belief-forming process with the use of belief's that are obtained by that very process since such self-dependent justification is circular. Harold Brown ([1993]) argued in this journal that some cases of self-dependent justification are legitimate despite their circularity. I argue instead that under appropriate construal many cases of self-dependent justification are not truly circular but are instances of ordinary Bayesian confirmation, and (...) hence they can raise the probability of the hypothesis as legitimately as any such confirmation does. I shall argue in particular that despite its dependence on perception we can use naturalized epistemology to confirm the reliability of a perceptual process without circularity. (shrink)

From one perspective, the fundamental notions of point-set topology have to do with sequences (of points or of numbers) and their limits. A broad class of epistemological questions also appear to be concerned with sequences and their limits. For example, problems of empirical underdetermination–which of a collection of alternative theories is true–have to do with logical properties of sequences of evidence. Underdetermination by evidence is the central problem of Plato’s Meno [Glymour and Kelly 1992], of one of Sextus Empiricus’ many (...) skeptical doubts, and arguably it is the idea in Kant’s antinomies, for example of the infinite divisibility of matter [Kelly 1995, Ch.3]. Many questions of methodology, or of the logic of discovery, have to do with sequences and their limits, for example under what conditions Bayesian procedures, which put a prior probability distribution over alternative hypotheses and possible evidence and form conditional probabilities as new evidence is obtained, converge to the truth ([Savage 1954], [Hesse 1970], [Osherson and Weinstein 1988], [Juhl 1993]). Some analyses of “S knows that p” seem to appeal to properties of actual and possible sequences of something–for example Nozick’s proposal that knowledge of p is belief in p produced by a method that would not produce belief in p if p were false and would produce belief in p if p were true. Even questions about finding the truth under a quite radical relativism, in which truth 1 depends on conceptual scheme and conceptual schemes can be altered, have been analyzed as a kind of limiting property of sequences [Kelly et al. 1994].

Given a traditional intuitionist moral epistemology, it is notoriously difficult for moral realists to explain the reliability of our moral beliefs. This has led some to go looking for an alternative to intuitionism. Perception is an obvious contender. I previously argued that this is a dead end, that all moral perception is dependent on a priori moral knowledge. This suggests that perceptualism merely moves the bump in the rug where the reliability challenge is concerned. Preston Werner responds (...) that my account rests on an overly intellectualized model of perception. In this paper, I argue that though Werner may well be correct, my arguments, properly extended, still suggest that perceptualism leaves realists in no better position than intuitionism when it comes to the reliability challenge.

The paper provisionally accepts the goal of Goldman's primary epistemics, which is to seek reliability values for basic cognitive processes, and questions whether such values may plausibly be expected. The reliability of such processes as perception and memory is dependent on other aspects of cognitive structure, and especially on one's "conceptual scheme," the evaluation of which goes beyond primary epistemics (and its dependence on cognitive science) to social epistemics, or indeed to traditional epistemology and philosophy of science. (...) Two general arguments against the plausibility of determining reliability values for the basic cognitive architecture of humans are proposed, one applying Fodor's distinction between input and central systems, and the other invoking a point by Geertz about culture and evolution. Social epistemics is only briefly evaluated, as it is nascent. (shrink)

This paper explores how data serve as evidence for phenomena. In contrast to standard philosophical models which invite us to think of evidential relationships as logical relationships, I argue that evidential relationships in the context of data-to-phenomena reasoning are empirical relationships that depend on holding the right sort of pattern of counterfactual dependence between the data and the conclusions investigators reach on the phenomena themselves.

Except the two types of state, complete failure and perfect functioning, some intermediate states also existed between those two states. This characteristic enables multistate system whose components are often of more than two states. Moreover, because of dependence between components, common cause failure enhances the failure risk of components during the operating period of MSS. A protection mechanism needs to be adopted because of the importance of certain components. For a MSS with CCF and protection mechanism, its reliability can (...) be evaluated by a proposed approach. Certain components not only can cause failure at one state, but also can cause failure to other components because of the CCF. Under the impact of one type of CCF, those components can constitute a specific group that can overlap with certain components. Universal generating function is adopted to incorporate the CCF and protection mechanism of a component. Consequently, reliability indices of a MSS can be evaluated by the proposed approach based on UGF. Examples and comparisons illustrate and validate this method. This method can also help engineers prioritize elements that require protection mechanism under various resource limitations. (shrink)

The stopping rule for a sequential experiment is the rule or procedure for determining when that experiment should end. Accordingly, the stopping rule principle (SRP) states that the evidential relationship between the final data from a sequential experiment and a hypothesis under consideration does not depend on the stopping rule: the same data should yield the same evidence, regardless of which stopping rule was used. I clarify and provide a novel defense of two interpretations of the main argument against the (...) SRP, the foregone conclusion argument. According to the first, the SRP allows for highly confirmationally unreliable experiments, which concept I make precise, to confirm highly. According to the second, it entails the evidential equivalence of experiments differing significantly in their confirmational reliability. I rebut several attempts to deflate or deflect the foregone conclusion argument, drawing connections with replication in science and the likelihood principle. (shrink)

In this article I formulate a skeptical argument against the possibility of adhering to the divine will in a non-accidental way. In particular, my focus in the article is on a widely embraced modal condition of accidentality, according to which non-accidentality has to do with a person manifesting dispositions that result in a given outcome in a modally robust way. The skeptical argument arises from two observations: first, various authors in the epistemology of religion have argued that it is often (...) not possible to reason reliably about religious matters, and second, non-accidentally adhering to a given norm is often associated with reasoning about the requirements of the norm in question in a reliable way. In addition to pointing out the existence of the argument, I outline strategies in which religious thinkers could reasonably challenge it by denying that reliable reasoning about the requirements of divine will is necessary for adhering to it in a non-accidental manner. Hence, I argue that the possibility of non-accidental adherence to the divine will does not depend solely on whether it is possible to reliably reason about what it requires one to do. (shrink)

Evolutionary socioecological theory and research proposing linking parasites with human social organization is uncommon and therefore welcome. However, more generally, condition-dependent adaptive phenotypic plasticity requires environmental uncertainty on a small scale, accompanied by reliable cues. In addition, genes in parasites may select among biologically adaptive cultural alternatives directly without necessarily going through human genetic predispositions, resulting in inter-specific gene-culture coevolution.

Researchers have recently begun to question the specificity and reliability of conflict adaptation effects, also known as sequential congruency effects, a highly cited effect in cognitive psychology. Some have even used the lack of reliability across tasks to argue against models of cognitive control that have dominated the field for decades. The present study tested the possibility that domain-general processes across tasks might appear on more sensitive mouse-tracking metrics rather than overall reaction times. The relationship between SCE effects (...) on the Stroop and Flanker tasks were examined for the first time using a mouse-tracking paradigm. Three main findings emerged: Robust SCEs were observed for both the Stroop and Flanker tasks at the group level, Within-task split-half reliabilities for the SCE across dependent variables were weak at best and non-existent in many cases, and SCEs for the Flanker and Stroop tasks did not correlate with each other for overall reaction times, but did show significant correlations between tasks on more dynamic measures that captured processes before response execution. These findings contribute to the literature by highlighting how mouse-tracking may be a fruitful avenue by which future studies can examine the specificity and reliability of conflict adaptation and tease apart different theoretical models producing the effects.

Scholars have long posited justice as a core value of public relations. However, that value has been criticized as being improbably idealistic. Philosopher David Hume locates the origins of justice within the need for property and the reliable exchange of resources. Hume thus embeds the origins of justice within a staple of public relations theory: resource dependency theory. Additionally, Hume believes a respect for justice to be the foundation of a positive reputation. This grounding of the quest for justice in (...) resource dependency and reputation helps establish a realistic basis for accepting justice as a core value of public relations. (shrink)

Function-first epistemologists analyze epistemic concepts, norms, and practices by investigating their functions. According to the most prominent function-first account, the primary function of our concept of knowledge is identifying reliable informants. In this paper, I take for granted the function-first methodology to achieve three main goals: First, I argue against this prominent account: studying practices of knowledge attribution and denial related to epistemic dependence, coordination, and competition reveals that the primary function of our concept of knowledge is not identifying reliable (...) informants. Second, I recommend that function-firsters accept an alternative account: the primary function of our concept of knowledge is identifying those who have eliminated all relevant alternatives. Finally, I diagnose the error that has led function-firsters to their account: they base their investigation into the nature of knowledge on the situation of inquirers seeking informants, a situation that does not reflect the complexity of our epistemic condition.

When individuals learn from what others tell them, the information is subject to transmission error that does not arise in learning from direct experience. Yet evidence shows that humans consistently prefer this apparently more unreliable source of information. We examine the effect this preference has in cases where the information concerns a judgment on others’ behaviour and is used to establish cooperation in a society. We present a spatial model confirming that cooperation can be sustained by gossip containing a high (...) degree of uncertainty. Accuracy alone does not predict the value of information in evolutionary terms; relevance, the impact of information on behavioural outcomes, must also be considered. We then show that once relevance is incorporated as a criterion, second-hand information can no longer be discounted on the basis of its poor fidelity alone. Finally we show that the relative importance of accuracy and relevance depends on factors of life history and demography. (shrink)

This paper explores a distinction between two types of response- dependence (RD) account (shallow vs. deep). This distinction is inherent in much of the existing literature, however it is neither widely nor well understood, and has never been drawn explicitly. The distinction is often taken to be a metaphysical, or ‘realism-relevant’ one—i.e. deep RD accounts entail qualified realism (or perhaps anti-realism), while shallow RD accounts are metaphysically neutral. I argue that the distinction is not reliably realism-relevant. I formulate a weaker (...) version of the distinction that may help prevent some common and understandable confusion about RD biconditionals and their relationship to realism. The weaker distinction rests on the different roles assigned to RD biconditionals by the two types of account. (shrink)

While we cannot directly measure the psychological preferences of individuals, and the moral, emotional, and cognitive tendencies of people from the past, we can use cultural artifacts as a window to the zeitgeist of societies in particular historical periods. At present, an increasing number of digitized texts spanning several centuries is available for a computerized analysis. In addition, developments form historical economics have enabled increasingly precise estimations of sociodemographic realities from the past. Crossing these datasets offer a powerful tool to (...) test how the environment changes psychology and vice versa. However, designing the appropriate proxies of relevant psychological constructs is not trivial. The gold standard to measure psychological constructs in modern texts – Linguistic Inquiry and Word Count – has been validated by psychometric experimentation with modern participants. However, as a tool to investigate the psychology of the past, the LIWC is limited in two main aspects: it does not cover the entire range of relevant psychological dimensions and the meaning, spelling, and pragmatic use of certain words depend on the historical period from which the fiction work is sampled. These LIWC limitations make the design of custom tools inevitable. However, without psychometric validation, there is uncertainty regarding what exactly is being measured. To overcome these pitfalls, we suggest several internal and external validation procedures, to be conducted prior to diachronic analyses. First, the semantic adequacy of search terms in bags-of-words approaches should be verified by training semantic vector spaces with the historical text corpus using tools like word2vec. Second, we propose factor analyses to evaluate the internal consistency between distinct bag-of-words proxying the same underlying psychological construct. Third, these proxies can be externally validated using prior knowledge on the differences between genres or other literary dimensions. Finally, while LIWC is limited in the analysis of historical documents, it can be used as a sanity check for external validation of custom measures. This procedure allows a robust estimation of psychological constructs and how they change throughout history. Together with historical economics, it also increases our power in testing the relationship between environmental change and the expression of psychological traits from the past. (shrink)

Aims : The Modified Reasons for Smoking Scale (MRSS) is a widely accepted scale that measures psychological functions of smoking. The scale has been translated in Dutch and has been validated, in order to be used in clinical smoking cessation practice in the Dutch-speaking part of Belgium. This study examined the factorial structure, reliability and validity of the scale in a sample of smokers, who are characterized by a high level of dependence and an explicit motivation to stop smoking. (...) Method : The participants were 383 smokers, who volunteered at the stop-smoking clinic of a Belgian university hospital, and completed the translated scale. They were administered the translated MRSS, the Fagerstrom Test for Nicotine Dependence (FTND). Through a clinical interview, smoking behaviour and smoking history was assessed (daily smoking consumption, years smoking, number of quit attempts, weeks stopped, alcohol and coffee consumption, CO level). Exploratory factor analysis was performed. Internal consistency was studied in order to examine the reliability. The concurrent validity was assessed by means of manova, anova and correlation analysis. Results : Factor analysis identified four factors, named stimulation, pleasure of smoking, social smoking and automatism of smoking. Cronbach's alpha ranged from 0.65 (automatism) to 0.72 (stimulation). manova indicated the influence of the variables age, sex, daily consumption and the FTND (the latter two variables showed a dose-dependent association with each subscale). Regression analysis revealed a relationship with dependence indicators, namely: the daily consumption, the number and duration of previous quit attempts, FTND, CO level and daily coffee intake. Conclusions : The Dutch translation of the MRSS identified four factors and revealed acceptable validity and reliability. The adapted version of the translated scale as a component of the psychological assessment procedure in a smoking cessation treatment in Dutch-speaking areas should be implemented. (shrink)

Many commentators have argued that on Hume’s account, pride turns out to be something that is unstable, context-dependent, and highly contingent. On their readings, whether or not an agent develops pride depends heavily on factors beyond her control, such as whether or not her house, which is beautiful, is also the most beautiful in her neighborhood and whether or not her neighbors will admire the beauty of her house rather than become envious of it. These aspects of Hume’s theory (...) of pride, the peculiarity requirement and the social dependency of pride, stand in tension with Hume’s claims that virtue reliably produces pride-in-virtue and that pride-in-virtue serves as a powerful motive to virtue. If pride depends on the affirmation of others and arises only from qualities that are peculiar to their possessor, will the virtuous person reliably develop pride-in-virtue? And if not, can pride-in-virtue serve the motivational role Hume attributes to it? This paper tackles these problems by showing how the virtuous develop pride-in-virtue and how the desire for pride-in-virtue can serve as a powerful and admirable motive to virtue. (shrink)

This article presents results from a simulation‐based study of inheritance inference, that is, inference from the typicality of a property among a “base” class to its typicality among a subclass of the class. The study aims to ascertain which kinds of inheritance inferences are reliable, with attention to the dependence of their reliability upon the type of environment in which inferences are made. For example, the study addresses whether inheritance inference is reliable in the case of “exceptional subclasses” (i.e., (...) subclasses that are known to be atypical in some respect) and attends to variations in reliability that result from variations in the entropy level of the environment. A further goal of the study is to show that the reliability of inheritance inference depends crucially on which sorts of base classes are used in making inferences. One approach to inheritance inference treats the extension of any atomic predicate as a suitable base class. A second approach identifies suitable base classes with the cells of a partition (of a preselected size k) of the domain of objects that satisfies the condition of maximizing the similarity of objects that are assigned to the same class. In addition to permitting more inferences, our study shows that the second approach results in inheritance inferences that are far more reliable, particularly in the case of exceptional subclasses.

To avoid post-neurosurgical language deficits, intraoperative mapping of the language function in the brain can be complemented with preoperative mapping with functional magnetic resonance imaging. The validity of an fMRI “language localizer” paradigm crucially depends on the choice of an optimal language task and baseline condition. This study presents a new fMRI “language localizer” in Russian using overt sentence completion, a task that comprehensively engages the language function by involving both production and comprehension at the word and sentence level. The (...) paradigm was validated in 18 neurologically healthy volunteers who participated in two scanning sessions, for estimating test–retest reliability. For the first time, two baseline conditions for the sentence completion task were compared. At the group level, the paradigm significantly activated both anterior and posterior language-related regions. Individual-level analysis showed that activation was elicited most consistently in the inferior frontal regions, followed by posterior temporal regions and the angular gyrus. Test–retest reliability of activation location, as measured by Dice coefficients, was moderate and thus comparable to previous studies. Test–retest reliability was higher in the frontal than temporo-parietal region and with the most liberal statistical thresholding compared to two more conservative thresholding methods. Lateralization indices were expectedly left-hemispheric, with greater lateralization in the frontal than temporo-parietal region, and showed moderate test-retest reliability. Finally, the pseudoword baseline elicited more extensive and more reliable activation, although the syllable baseline appears more feasible for future clinical use. Overall, the study demonstrated the validity and reliability of the sentence completion task for mapping the language function in the brain. The paradigm needs further validation in a clinical sample of neurosurgical patients. Additionally, the study contributes to general evidence on test–retest reliability of fMRI. (shrink)

Merging beliefs depends on the relative reliability of their sources. When this is information is absent, assuming equal reliability is unwarranted. The solution proposed in this article is that every reliability profile is possible, and only what holds according to all of them is accepted. Alternatively, one source is completely reliable, but which one is not specified. These two cases motivate two existing forms of merging: maxcons-based merging and disjunctive merging.

Medical expertise plays a major role in large-scale welfare arrangements, for example, in private insurance companies. It symbolizes the objectivity and reliability of the procedures of risk selection and legitimates the acceptance and rejection of clients. To understand "reliability" in this context, this article discusses the introduction of chemical urine analysis for life insurance examination between 1880 and 1920. The article argues that reliability of urine analysis is not an intrinsic characteristic of the technology and thus cannot (...) serve as the explanation for the relevance of this technology as a means of risk selection. The construction of a "reliable technology" went hand in hand with the development of a standardized, uniform, and predictable performance of the test and an emergence of specific network—namely, a large-scale, bureaucratic insurance practice in which examination rooms of physicians became connected to the head offices of insurance companies by administrative means. During this process, the balance of power between medical examiners and insurance companies was reversed. Insurance compa nies depended on medicine for risk selection, but physicians increasingly had to act according to the rules set by life insurance companies. (shrink)

Several versions of the dot probe detection task are frequently used to assess maladaptive attentional processes associated with a broad range of psychopathology and health behavior, including eating behavior and weight. However, there are serious concerns about the reliability of the indices derived from the paradigm as measurement of attentional bias toward or away from salient stimuli. The present paper gives an overview of different attentional bias indices used in psychopathology research and scrutinizes three types of indices calculated from (...) a pictorial version of the dot probe task to assess food-related attentional biases in children and youngsters with and without obesity. Correlational analyses reveal that dynamic scores are dependent on general response speed. Reliability estimates are low for the traditional and probability indices. The higher reliability for the dynamic indices is at least partially explained by general response speed. No significant group differences between youth with and without obesity are found, and correlations with weight are also non-significant. Taken together, results cast doubt on the applicability of this specific task for both experimental and individual differences research on food-related attentional biases in youth. However, researchers are encouraged to make and test adaptations to the procedure or computational algorithm in an effort to increase psychometric quality of the task and to report psychometric characteristics of their version of the task for their specific sample.

It is rather uncontroversial that gender should have no influence on treating others as equal epistemic agents. However, is this view reflected in practice? This paper aims to test whether the gender of the testifier and the accused of assault is related to the perception of a testimony’s reliability and the guilt of the potential perpetrator. Two experiments were conducted: the subjects (n = 361, 47% females, 53% males) assessed the reliability of the testifier in four scenarios of (...) assault accusation, in which the only difference was the gender of the people presented. During the study, we have observed dependencies of gender and ascription of reliability, but only marginal differences in guilt attribution. The results of our research may constitute an argument for the existence of different epistemic status endowed on people depending on their gender and existing gender stereotypes. Our results suggest that gender bias may be situated at a deeper level than the linguistically triggered representation. (shrink)

The development of complex autonomous systems that use artificial intelligence (AI) is changing the nature of conflict. In practice, autonomous systems will be extensively tested before being operationally deployed to ensure system behavior is reliable in expected contexts. However, the complexity of autonomous systems means that they will demonstrate emergent behavior in the open context of real-world conflict environments. This article examines the novel implications of emergent behavior of autonomous AI systems designed for conflict through two case studies. These case (...) studies include (1) a swarm system designed for maritime intelligence, surveillance, and reconnaissance operations, and (2) a next-generation humanitarian notification system. Both case studies represent current or near-future technology in which emergent behavior is possible, demonstrating that such behavior can be both unpredictable and more reliable depending on the level at which the system is considered. This counterintuitive relationship between less predictability and more reliability results in unique challenges for system certification and adherence to the growing body of principles for responsible AI in defense, which must be considered for the real-world operationalization of AI designed for conflict environments.

Truth Matters is the first full-length introduction to response-dependence, a topic that has become a main focus of interest for philosophers across a wide range of disciplines and subject areas.The response-dependence claim, in brief, is to provide a 'third way' between the realist (or objectivist) conception of truth as always potentially transcending the limits of human ascertainment and the anti-realist (or verificationist) case that truth cannot possibly transcend those limits since then we could never acquire or manifest a knowledge of (...) it.While setting out the issues clearly and concisely, Norris also provides some relevant background history to this current debate, including discussion of its sources and analogues in Plato, Locke, Kant and Wittgenstein. His book offers invaluable guidance for student readers in search of a reliable introductory survey of the field. Among those with a more specialist interest it may sometimes provoke disagreement, as when Norris argues that the response-dependence approach often goes along with a disguised anti-realist bias and hence fails to make good on its 'third-way' promise. However, its combination of wide-ranging coverage with clarity of focus and depth of philosophical treatment will be welcomed.Key Features:*Clear, accessible account of some complex philosophical issues;*First book-length study of the response-dependence debate;*Informative discussion of its pre-history in philosophers from Plato to Hume, Locke and Kant;*Aimed at readers seeking a reliable, well-informed introductory account while relevant to those with a more specialist knowledge of the topic.

Filling out long questionnaires can be frustrating, unpleasant, and discouraging for respondents to continue. This is why shorter forms of long instruments are preferred, especially when they have comparable reliability and validity. In present study, two short forms of the Cross-cultural Personality Assessment Inventory were developed and validated. The items of the short forms were all selected from the 28 personality scales of the CPAI-2 based on the norm sample. Based on some priori criteria, we obtained the appropriate items (...) and constructed the 56-item Chinese Personality Assessment Inventory and the 28-item CPAI. Then, we examined the factor structure of both short forms with Exploratory SEM and replicated the four-factor structure of the original CPAI-2, reflecting the four personality domains of Chinese people, namely, Social Potency, Dependability, Accommodation, and Interpersonal Relatedness. Further analyses with ESEM models demonstrate full measurement invariance across gender for both short forms. The results show that females score lower than males on Social Potency. In addition, these four factors of both short forms have adequate internal consistency, and the correlation patterns of the four factors, the big five personality traits, and several health-related variables are extremely similar across the two short forms, reflecting adequate and comparable criterion validity, convergent validity, and discriminant validity. Overall, the short versions of CPAI-2 are psychometrically acceptable and have practically implications for measuring Chinese personality and cross-cultural research. (shrink)

This paper has two aims. One is to draw a distinction between two types of trust. The other is to argue for its applicability in academic discourse on educational policies. One of the two types of trust is ethical trust that rests on beliefs about others’ ethical virtues. The other is institutional trust that typically depends on law enforcement and economic incentives. Ideas about a social order based primarily on institutional trust have haunted political thought since the time of Thomas (...) Hobbes. Such ideas may seem realistic if we focus on business relations, where conformity to contractual terms suffices to meet the needs of all concerned. Intimate relationships rely more on ethical trust. In the first half of the paper the difference between these two types of trust is explained. In the final sections it is argued that successful schoolwork depends on ethical trust and that measures to make schools more reliable in the institutional sense, through supervision and accountability, need to be applied with caution. Such measures can undermine ethical trust because they, at least implicitly, question the moral integrity of teachers and school-heads. (shrink)

According to externalist reliabilism and dogmatic foundationalism, it's possible to gain knowledge through a perceptual experience without being in a position to know that the experience is reliable. As a result, both of these views face the problem of making knowledge of perceptual reliability too easy, for they permit deducing perceptual reliability from particular perceptual experience without already knowing that these experiences are trustworthy. Ernest Sosa advocates a two-stage solution to the problem. At the first stage, a rich (...) body of perceptual animal knowledge is acquired. At the second stage, perceptual knowledge becomes reflective after deducing perceptual reliability from the initial body of perceptual animal knowledge. I defend the alternative approach of rejecting both externalist reliabilism and dogmatic foundationalism. According to the alternative view, perceptual knowledge and knowledge of perceptual reliability require each other. Such a cognitive structure seems viciously circular. I propose that the appearance of vicious circularity dissipates when the relationship in question is viewed, not as one of temporal priority, but instead as synchronic mutual dependence. At a given time, one cannot have perceptual knowledge without knowledge of perceptual reliability, and vice versa. Such mutual dependence, I argue, is benign. (shrink)

According to Hartry Field, the mathematical Platonist is hostage of a dilemma. Faced with the request of explaining the mathematicians’ reliability, one option could be to maintain that the mathematicians are reliably responsive to a realm populated with mathematical entities; alternatively, one might try to contend that the mathematical realm conceptually depends on, and for this reason is reliably reflected by, the mathematicians’ (best) opinions; however, both alternatives are actually unavailable to the Platonist: the first one because it is (...) in tension with the idea that mathematical entities are causally ineffective, the second one because it is in tension with the suggestion that mathematical entities are mind-independent. John Divers and Alexander Miller have tried to reject the conclusion of this argument—according to which Platonism is inconsistent with a satisfactory epistemology for arithmetic—by redescribing the second horn of the dilemma in light of Crispin Wright’s notion of judgment-dependent truth; in particular they have contended that once arithmetical truth is conceived in this way the Platonist can have a substantial epistemology which does not conflict with the idea that the mathematical entities exist mind-independently. In this paper I analyze Wright’s notion of judgment-dependent truth, and reject Divers and Miller’s argument for the conclusion that arithmetical truth can be so characterized. In the final part, I address the worry that my argument generalizes very quickly to the conclusion that no area of discourse could be characterized as judgment-dependent. As against this conclusion, I indicate under what conditions—notably not satisfied in Divers and Miller’s case, but possibly satisfied in others—a discourse’s judgment-dependency can be successfully vindicated.

Hospital-dependent patients are individuals who are repeatedly readmitted to the hospital because their acute medical needs cannot be met elsewhere. Unlike the chronically critically ill, these patients do not have a continuous need for life-sustaining equipment and can experience periods of relative stability where they have a good quality of life. However, some end up spending months or even years in the hospital receiving resource-intensive care because they are unable to be safely discharged, despite an initial optimistic prognosis. It (...) is hard to reliably identify these patients on admission and more research is needed to better understand the unique medical needs of this population. But the inability to safely discharge these patients to their home or to a skilled nursing facility without rapid readmissions also creates ethical implications for the physicians who care for them. The aim of this paper is to clarify some of the ethical considerations involved in caring for hospital-dependent patients. Among physicians, the care of hospital-dependent patients is likely to disproportionately affect hospitalists and intensivists, whose care is often evaluated in terms of reducing patient length of stay and readmissions. Because hospital-dependent patients’ medical needs thwart the traditional goal of safe discharge, both clinical ethics and physicians’ professional obligations are implicated by their care. The inability to reliably identify these patients early can complicate discussions about treatment goals and informed consent. Similarly, the tremendous dedication of limited resources to these patients without safe discharge back to the community may raise concerns about the just allocation of healthcare resources. Our current acute care hospitals are not designed to provide long-term care for hospital-dependent patients. Unfortunately, safe discharge options remain elusive for these patients. Further research and support of this population is needed to more reliably identify hospital-dependent patients on admission, better inform the discussions of short- and long-term treatment goals, and more wisely allocate resources both within our acute care hospitals and larger healthcare system.

Generally, the testimony of intoxicated witnesses has been considered relatively unreliable, but recent research has nuanced the knowledge base regarding these vulnerable witnesses.PurposeTo demonstrate the application of recent research findings regarding intoxicated witnesses to the statements made by a key witness to the murder of Olof Palme, Sweden's prime minister, in 1986. An additional purpose was to illustrate the use of a nuanced calculation of blood alcohol concentration for researchers.MethodsThe Palme murder has been debated since the crime was committed and (...) no one has yet been sentenced. One of the witnesses was intoxicated and to estimate a range for his BAC at the time, a comprehensive BAC calculation was conducted in this study to illustrate important factors to consider in these types of cases.ResultsThrough the demonstration of the use of a nuanced BAC formula and by applying recent research results from studies on intoxicated witnesses, it was estimated that the possible BAC of the witness in the Palme-case at the time of the witnessed crime ranged between BAC = 0 to BAC = 0.13, depending on the type of alcoholic beverage consumed and whether the witness was a social or heavy drinker. This puts the witness either well within the span of maintained completeness as well as maintained accuracy rate, or slightly exceeding this span into the BAC-range of reduced completeness but maintained accuracy rate. He was questioned immediately, and thereafter repeatedly, and he reported similar information throughout the interviews, which is in line with previous results on information maintenance over repeated interviews among intoxicated witnesses.ConclusionThe current case example shows how recent research on intoxicated witnesses can be applied in praxis, illustrating important factors for legal practitioners to consider when interpreting information from intoxicated witnesses. It also provides legal practitioners and researchers with an example of a structured approach to more nuanced BAC-calculations. (shrink)
