The Continuous Parameter Estimation Model is applied to develop individual genomic-level heritabilities for the latent hierarchical structure and developmental dynamics of Life History (LH) strategy LH strategies relate to the allocations of bioenergetic resources into different domains of fitness. LH has moderate to high population-level heritability in humans, both at the level of the high-order Super-K Factor and the lower-order factors, the K-Factor, Covitality Factor, and General Factor of Personality (GFP). Several important questions remain unexplored. We developed measures of genome-level (...) heritabilities employing an American sample of 316 monozygotic (MZ) and 274 dizygotic (DZ) twin dyads and a Swedish sample of 863 MZ and 475 DZ twin dyads. This novel heritability index measures individual genetic transmissibility, therefore opening new avenues for analyzing complex interactions among heritable traits inaccessible to standard structural equations methods. For these samples: (1) moderate to high heritability of factor loadings of Super-K on its lower-order factors is demonstrated, evidencing biological preparedness, genetic accommodation, and the gene-culture coevolution of biased epigenetic rules of development; (2) moderate to high heritability of the magnitudes of the effect of the higher-order factors upon their loadings on their constituent factors, evidencing genetic constraints upon phenotypic plasticity; and (3) that heritability of the LH factors, of factor loadings, and of the magnitudes of the correlations among factors are weaker among those with slower LH speeds, demonstrating that inter-individual variation in transmissibility is a function of individual socioecological selection pressures.

on writing prescriptions.[2] These two reasons indicate why there are obvious repercussions for those who do not have reasonable access to physicians’ services. Of course, the word ‘reasonable’ is important here. After all, there is the old joke—for those who enjoy gallows humor—that the U.S. has universal access to healthcare so long as one is willing to commit a crime to see the county jail’s physician, or make one’s self sick enough to qualify for emergency services. Putting aside such extraordinary (...) measures, at least some deficit in accessing physicians’ services can be made up through consulting written medical knowledge. Many libraries have medical textbooks, and the Internet has many good sites that contain medical knowledge. Of course, all the knowledge in the world is not going to do much good if treatment requires a prescription. The physicians’ monopoly on writing prescriptions means that nothing (legal[3]) can be done in terms of treatment if one does not have access to the services of a qualified physician. This state of affairs is unjust. A just society cannot have it both ways: legislation cannot say both that the expertise of physicians is so precious that only they can prescribe medicine AND not everyone is guaranteed reasonable access to their services. If there is no guarantee of reasonable access then physicians should not have a monopoly on writing prescriptions, and if there is a monopoly on writing prescriptions then people should have reasonable access to their services.

There are indications that simple reaction time might have slowed in Western countries, based on both cohort- and multi-study comparisons. A possible limitation of the latter method in particular is measurement error stemming from methods variance, which results from the fact that instruments and experimental conditions change over time and between studies. We therefore set out to measure the simple auditory reaction time (SRT) of 7,081 individuals (2,997 males and 4,084 females) born in Sweden 1959-1985 (subjects were aged between (...) 27 and 54 years at time of measurement). Depending on cut-offs and adjustment for ageing related slowing on SRT, the data suggest that SRT has increased between 3 and 16 ms in the 27 birth years covered in the present sample. The slowing is unlikely to be explained by attrition, as evaluated by comparing the general intelligence × birth-year interactions and standard deviations for both male participants and dropouts, utilizing military conscript cognitive ability data. The present result is consistent with previous studies employing alternative methods, and may result from several synergistic factors, such as possible recent micro-evolutionary trends favouring lower g in Sweden and the effects of industrially produced neurotoxic substances on peripheral nerve conduction velocity.

Agnotology is the study of how ignorance arises via circulation of misinformation calculated to mislead. Legates et al. had questioned the applicability of agnotology to politically-charged debates. In their reply, Bedford and Cook, seeking to apply agnotology to climate science, asserted that fossil-fuel interests had promoted doubt about a climate consensus. Their definition of climate ‘misinformation’ was contingent upon the post-modernist assumptions that scientific truth is discernible by measuring a consensus among experts, and that a near unanimous consensus exists. However, (...) inspection of a claim by Cook et al. of 97.1 % consensus, heavily relied upon by Bedford and Cook, shows just 0.3 % endorsement of the standard definition of consensus: that most warming since 1950 is anthropogenic. Agnotology, then, is a two-edged sword since either side in a debate may claim that general ignorance arises from misinformation allegedly circulated by the other. Significant questions about anthropogenic influences on climate remain. Therefore, Legates et al. appropriately asserted that partisan presentations of controversies stifle debate and have no place in education. (shrink)

This paper examines the lack of health insurance coverage in the US as a public policy issue. It first compares the problem of health insurance coverage to the problem of unemployment to show that in terms of the numbers of individuals affected lack of health insurance is a problem comparable in importance to the problem of unemployment. Secondly, the paper discusses the methodology involved in measuring health insurance coverage, and argues that the current method of estimation of the uninsured underestimates (...) the extent that individuals go without health insurance. Third, the paper briefly introduces Amartya Sen's functionings and capabilities framework to suggest away of representing the extent to which individuals are uninsured. Fourth, the paper sketches a means of operationalizing the Sen representation of the uninsured in terms of the disability-adjusted life-year (DALY) measure. (shrink)

Beliefs come in degrees, and we often represent those degrees with numbers. We might say, for example, that we are 90% confident in the truth of some scientific hypothesis, or only 30% confident in the success of some risky endeavour. But what do these numbers mean? What, in other words, is the underlying psychological reality to which the numbers correspond? And what constitutes a meaningful difference between numerically distinct representations of belief? In this Element, we discuss the main approaches to (...) the measurement of belief. These fall into two broad categories—epistemic and decision-theoretic—with divergent foundations in the theory of measurement. Epistemic approaches explain the measurement of belief by appeal to relations between belief states themselves, whereas decision-theoretic approaches appeal to relations between beliefs and desires in the production of choice and preferences. -/- (This book is part of the Cambridge Elements in Decision Theory and Philosophy series.).

BackgroundThe merits and drawbacks of moral relevance models of addiction have predominantly been discussed theoretically, without empirical evidence of these potential effects. This study develops and evaluates a novel survey measure for assessing moral evaluations of patient substance misuse (ME-PSM).MethodsThis measure was tested on 524 health professionals (i.e., physicians, nurses, and other health professionals) in California (n = 173), urban France (n = 102), and urban China (n = 249). Demographic factors associated with ME-PSM were investigated using analyses of variance (...) (ANOVAs) and t-tests, with results suggesting that ME-PSM is higher among younger health professionals, nurses (when compared with physicians and other health professionals), and Chinese health professionals (when compared with French and American health professionals).ResultsResults provide preliminary support for the psychometric quality of the survey measure introduced in this study, including the existence of a single latent structure and partial invariance of collected data across countries.ConclusionThe survey measure for ME-PSM which was developed and tested in the current study appears to hold potential utility for use as a measure of moral views of patient substance misuse. With development, this measure may be used to examine moral evaluations, both as factors of stigma and of other clinical factors associated with the treatment of patients with substance use disorders.

David Cooper explores and defends the view that a reality independent of human perspectives is necessarily indescribable, a "mystery." Other views are shown to be hubristic. Humanists, for whom "man is the measure" of reality, exaggerate our capacity to live without the sense of an independent measure. Absolutists, who proclaim our capacity to know an independent reality, exaggerate our cognitive powers. In this highly original book Cooper restores to philosophy a proper appreciation of mystery-that is what provides a measure of (...) our beliefs and conduct. (shrink)

The measurement of sensory intensity has had a long history, attracting the attention of investigators from many disciplines including physiology, psychology, physics, mathematics, philosophy, and even chemistry. While there has been a continuing doubt by some that sensation has the properties necessary for measurement, experiments designed to obtain estimates of sensory intensity have found that a general rule applies: Equal stimulus ratios produce equal sensory ratios. Theories concerning the basis for this simple psychophysical rule are discussed, with emphasis (...) given to the physical correlate theory, which considers judgments of subjective magnitudes to be based upon estimates of physical dimensions that vary regularly with changes in degree of stimulation. For the most thoroughly investigated sensory scales, brightness and loudness, the physical correlate is considered to be distance. Our “tacit knowledge” of the sensory effects of changing distance plays an essential role in matching motor activities to environmental conditions and in ensuring accurate perceptual evaluations through brightness and loudness constancies. In psychophysical experiments, subjects apparently use this same tacit knowledge when required to estimate relative subjective magnitudes. The evidence related to the physical correlate theory is summarized, and it is concluded that, while under appropriate conditions we demonstrate considerable skill in evaluating environmental relationships, we are quite unable to estimate the neurophysiological nature or quantity of sensory response. A psychophysics devoted to studying conditions required for accuracy and conditions producing errors in the perception of environmental relationships would seem to be more valuable than one devoted to subjective magnitudes.

The debate on probabilistic measures of coherence flourishes for about 15 years now. Initiated by papers that have been published around the turn of the millennium, many different proposals have since then been put forward. This contribution is partly devoted to a reassessment of extant coherence measures. Focusing on a small number of reasonable adequacy constraints I show that (i) there can be no coherence measure that satisfies all constraints, and that (ii) subsets of these adequacy constraints motivate two different (...) classes of coherence measures. These classes do not coincide with the common distinction between coherence as mutual support and coherence as relative set-theoretic overlap. Finally, I put forward arguments to the effect that for each such class of coherence measures there is an outstanding measure that outperforms all other extant proposals. One of these measures has recently been put forward in the literature, while the other one is based on a novel probabilistic measure of confirmation. (shrink)

One of the most challenging questions surrounding subjective animal welfare is whether these states are measurable: that is, is subjective welfare an appropriately quantifiable target for scientific enquiry and ethical and deliberative calculation? The availability of several different types of measurement scale raises important questions regarding whether subjective experience has the right properties to be meaningfully represented on the types of scale required for different applications. This methodological question has so far received scant attention in the animal welfare literature. (...) In this paper, I address this omission by examining the types of measurement scale we can reasonably expect to apply to animal welfare measurements, and which we will actually need for our applications. I argue that our different applications will require variously ordinal, interval, and ratio scales, and that we have sufficient reason to believe that subjective welfare is a target with the appropriate characteristics to justify the practice of representing it using each of these types of scales.

One could say that we are human beings to the degree to which our conscience is developed. My paper analyses the conscience from an ethical point of view and states that it is to be understood as the measure of morality within a person. [‘Moral’ refers to a sense of right and wrong, and ethics to the principles of “good” and “bad” agreed by a society]. Taking into consideration that there are people who feel an acute sense of guilt when (...) committing a crime and others who feel nothing, my work tries to identify the factors responsible for such a state of affairs. Therefore, it deals with the question, “Why are there considerable differences among people from the point of view of morality?”. I shall elaborate mainly on the role of education and genetic heritage, which are instrumental in the development of moral conscience within a person. Their influence in shaping it is ensured by the activity of the neurons and of other processes within the brain, which firstly produce the human consciousness. Other elements ‘grow’ on it. (shrink)

When making decisions about action to improve animal lives, it is important that we have accurate estimates of how much animals are suffering under different conditions. The current frameworks for making comparative estimates of suffering all fall along the lines of multiplying numbers of animals used by length of life and amount of suffering experienced. However, the numbers used to quantify suffering are usually generated through unreliable and subjective processes which make them unlikely to be correct. In this paper, I (...) look at how we might apply principled methods from animal welfare science to arrive at more accurate scores, which will then help us in making the best decisions for animals. I argue that a combined use of both a whole-animal measure and a combination measurement framework for assessing welfare will give us the most accurate answers to guide our action. (shrink)

It is often said that one person or society is `freer' than another, or that people have a right to equal freedom, or that freedom should be increased or even maximized. Such quantitative claims about freedom are of great importance to us, forming an essential part of our political discourse and theorizing. Yet their meaning has been surprisingly neglected by political philosophers until now. Ian Carter provides the first systematic account of the nature and importance of our judgements about degrees (...) of freedom. He begins with an analysis of the normative assumptions behind the claim that individuals are entitled to a measure of freedom, and then goes on to ask whether it is indeed conceptually possible to measure freedom. Adopting a coherentist approach, the author argues for a conception of freedom that not only reflects commonly held intuitions about who is freer than who but is also compatible with a liberal or freedom-based theory of justice.

There are many decision contexts in which we require accurate information on animal welfare, in ethics, management, and policy. Unfortunately, many of the methods currently used for estimating animal welfare in these contexts are subjective and unreliable, and thus unlikely to be accurate.

I construct and apply (...) a framework of desiderata for welfare measures, to assess the best of the currently available methods and argue that a combined use of both a whole-animal measure and a combination measurement framework for assessing welfare will give us the most accurate answers to guide our action.

Researchers in child development and education around the world, many of whom have worked with interim versions of the system, indeed, all those seriously interested in understanding the problem of moral judgment, will find it an indispensable resource. Volume I reviews Kohlberg's stage theory, and the by-now large body of research on (...) the significance and utility of his moral stages. Issues of reliability and validity are addressed. The volume ends with detailed instructions for using the forms in Volume 2. Volume 2, in a specially-designed, user-friendly format, includes three alternative functionally-equivalent forms of the scoring system. (shrink)

What is it to know more? By what metric should the quantity of one's knowledge be measured? I start by examining and arguing against a very natural approach to the measure of knowledge, one on which how much is a matter of how many. I then turn to the quasi-spatial notion of counterfactual distance and show how a model that appeals to distance avoids the problems that plague appeals to cardinality. But such a model faces fatal problems of its own. (...) Reflection on what the distance model gets right and where it goes wrong motivates a third approach, which appeals not to cardinality, nor to counterfactual distance, but to similarity. I close the paper by advocating this model and briefly discussing some of its significance for epistemic normativity. In particular, I argue that the 'trivial truths' objection to the view that truth is the goal of inquiry rests on an unstated, but false, assumption about the measure of knowledge, and suggest that a similarity model preserves truth as the aim of belief in an intuitively satisfying way.

Next SectionAn attempt to resolve the controversy regarding the solution of the Sleeping Beauty Problem in the framework of the Many-Worlds Interpretation led to a new controversy regarding the Quantum Sleeping Beauty Problem. We apply the concept of a measure of existence of a world and reach the solution known as ‘thirder’ solution which differs from Peter Lewis’s ‘halfer’ assertion. We argue that this method provides a simple and powerful tool for analysing rational decision theory problems.

The contribution of this work is a classification of corporate social action underlying the Social Ratings Data compiled by Kinder Lydenburg Domini Analytics, Inc. We compare extant typologies of corporate social action to the results of our exploratory factor analysis. Our findings indicate four distinct latent constructs that bear resemblance to concepts discussed in prior literature. Akey finding of our research is that positive and negative social action are both empirically and conceptually distinct constructs and should not be combined in (...) future research. Additionally, we recommend that some prior research results be reconsidered to determine whether these newly derived measures might clarify some previous findings. (shrink)

Consciousness can be measured in various ways, but different measures often yield different conclusions about the extent to which awareness relates to performance. Here, we compare five different subjective measures of awareness in the context of an artificial grammar learning task. Participants expressed their subjective awareness of rules using one of five different scales: confidence ratings , post-decision wagering , feeling of warmth , rule awareness , and continuous scale . All scales were equally sensitive to conscious knowledge. PDW, however, (...) was affected by risk aversion, and both RAS and SDS applied different minimal criteria for rule awareness. CR seems to capture the largest range of consciousness, but failed to indicate unconscious knowledge with the guessing criterion. We close by discussing the theoretical implications of scale sensitivity and propose that CR’s unique features enable a finer assessment of subjective states of awareness. (shrink)

The deflationary aim of this book, which occupies Part I, is to show that a widely held view has little to be said for it. The constructive aim, pursued in Part II, is to make plausible a measure-theoretic account of propositional attitudes. The discussion is throughout instructive, illuminating and sensitive to the many intricacies surrounding attitude ascriptions and how they can carry information about a subject's psychology. There is close engagement with cognitive science. The book should be read by anyone (...) seriously engaged with issues about propositional attitudes.According to the widely held view, which Matthews calls the Received View, the attitude of Φing that p is a matter of standing in a computational/functional relation to an explicit Representation that expresses the proposition that p, and thinking is ‘an inferential computational process defined over one or more of these Representations that eventuates in the production of either another Representation or a behavior’. The representations are understood to be sentences in a language of thought and thus to have a compositional syntax and semantics. The theory that Matthews aims to make plausible has it that ascriptions of propositional attitudes in the form ‘X Φs that p’, ascribe a state to a person by relating that person to an abstract object that is the representative of the state in roughly the way that numbers on a scale are the measure-theoretic representations of certain physical magnitudes. We are to think of the role of ‘Jones believes that interest rates will fall’ by analogy with that of ‘Jones weighs 150lbs’. The latter depends on there being arithmetical relations defined over numbers that enable its particular assignment of a number to Jones's weight to represent physical properties that Jones has in virtue ….

This article analyses the relationship between the concept of single aspect similarity and proposed measures of similarity. More precisely, it compares eleven measures of similarity in terms of how well they satisfy a list of desiderata, chosen to capture common intuitions concerning the properties of similarity and the relations between similarity and dissimilarity. Three types of measures are discussed: similarity as commonality, similarity as a function of dissimilarity, and similarity as a joint function of commonality and difference. Relative to the (...) desiderata, it is found that a measure of the second type fares the best. However, rather than recommend this measure alone as a measure of similarity, it is suggested that there are at least three separate concepts of single aspect similarity, corresponding to the three types of measures. In light of this proposal, three of the eleven measures (and variants of these) are deemed acceptable. (shrink)
