SummaryVisual acuity was tested and the anterior portion of the eye inspected among the Gidra in Lowland Papua New Guinea, who depend on hunting for their animal food. The visual acuity of the youths and adults was as high as that of hunters and gatherers; 88% of the males and 81% of the females had an acuity of 1·2 or better. The elders had far lower acuity, correlated with the advance of cataract. The senescent visual acuity is discussed in relation (...) to little practice and low productivity of the elders' hunting, and to the Gidra traditional age-grade system. (shrink)

The dramatic events of the crisis have reignited debates on the independence of central banks and the scope of their mandates. In this article, I contribute to the normative understanding of these developments by discussing John Rawls’s position in debates of the 1950s and 1960s on the independence of the US Federal Reserve. Rawls’s account of the central bank in his property-owning democracy, Democratic Central Banking (DCB), assigns authority over monetary policy directly to the government and prioritizes low unemployment over (...) price stability. I contrast DCB with Central Bank Independence (CBI), which requires that the central bank is independent of the government and pursues low inflation. I evaluate DCB by asking whether justice as fairness requires democratic control of the central bank and argue that it does not. Instead, so I argue, the choice between DCB and CBI should be justified in terms of the difference principle. By reflecting on central banking in a property-owning democracy, I cast new light on the Rawlsian realistic utopia of a just capitalist society, while also investigating democratic objections to today’s independent central banks.

In early major works, Cassirer and Schlick differently recast traditional doctrines of the concept and of the relation of concept to intuitive content along the lines of recent epistemological discussions within the exact sciences. In this, they attempted to refashion epistemology by incorporating as its basic principle the notion of functional coordination, the theoretical sciences' own methodological tool for dispensing with the imprecise and unreliable guide of intuitive evidence. Examining their respective reconstructions of the theory of knowledge provides an axis (...) of comparison along which to locate Cassirer's Neo-Kantianism and Schlick's pre-positivist empiricism, and an immediate background of contrast to the subsequent rise of logical empiricism. For in the absence of intuition all our knowledge is without objects and therefore remains entirely empty. (Kant A62/B87) And how awkward is the human mind in diving the nature of things when forsaken by the analogy of what we see and touch directly? (Boltzmann 1895). (shrink)

_Self-Reflection for the Opaque Mind_ attempts to solve a grave problem about critical self-reflection. Psychological studies indicate not just that we are bad at detecting our own "ego-threatening" thoughts; they also suggest that we are ignorant of even our ordinary thoughts. However, self-reflection presupposes an ability to know one’s own thoughts. So if ignorance is the norm, why attempt self-reflection? While admitting the psychological data, this book argues that we are infallible in a limited range of self-discerning judgments—that in some (...) cases, these judgments are self-fulfilling or self-verifying. Even so, infallibility does not imply indubitability, and the author does not wish to provide a "foundation" for empirical knowledge. The point is rather to explain how self-reflection as a rational activity is possible. The book will be of interest to scholars working on the issue of self-reflection across a wide range of disciplines, including philosophy, psychology, and cognitive science. (shrink)

Gametes, tissue, and organs can be taken from the dying or dead for reproduction, transplantation, and research. Whole bodies as well as parts can be used for teaching anatomy. While these uses are diverse, they have an ethical consideration in common: the claims of the people whose bodies are used. Is some use permissible only when people have consented to the use, actually wanted the use, would have wanted the use, not opposed the use, or what? The aim of this (...) article is to make progress in answering these questions. Initially I assume knowledge of people’s desires in order to test whether consent is directly required by their rights without worrying about mistaken uses against their wishes. I claim consent is not directly required by people’s rights. If we know people wanted or would want a use, their rights permit the use, but if we know they wanted or would want not to be used, their rights do not permit the use. The knowledge assumption is then dropped and the question becomes how to decide what to do when the wishes of rightholders are not known. I suggest working out what to do when wishes are known and then adjusting, on the basis of whatever evidence there is, for probability and strength of desire. There are other considerations too, for instance about default rules. The key general comment here is that, in setting rules, the costs to rightholders in not getting what they want needs to be taken into account. The final section tries to show that, in setting these rules, mistaken uses are not to be taken as worse than mistaken failure to use. (shrink)

The variety DMM of De Morgan monoids has just four minimal subvarieties. The join-irreducible covers of these atoms in the subvariety lattice of DMM are investigated. One of the two atoms consisting of idempotent algebras has no such cover; the other has just one. The remaining two atoms lack nontrivial idempotent members. They are generated, respectively, by 4-element De Morgan monoids C4 and D4, where C4 is the only nontrivial 0-generated algebra onto which finitely subdirectly irreducible De Morgan monoids may (...) be mapped by noninjective homomorphisms. The homomorphic preimages of C4 within DMM constitute a proper quasivariety, which is shown to have a largest subvariety U. The covers of the variety within U are revealed here. There are just ten of them. In exactly six of these ten varieties, all nontrivial members have C4 as a retract. In the varietal join of those six classes, every subquasivariety is a variety—in fact, every finite subdirectly irreducible algebra is projective. Beyond U, all covers of [or of ] within DMM are discriminator varieties. Of these, we identify infinitely many that are finitely generated, and some that are not. We also prove that there are just 68 minimal quasivarieties of De Morgan monoids. (shrink)

It was shown recently that epimorphisms need not be surjective in a variety K of Heyting algebras, but only one counter-example was exhibited in the literature until now. Here, a continuum of such examples is identified, viz. the variety generated by the Rieger-Nishimura lattice, and all of its (locally finite) subvarieties that contain the original counter-example K . It is known that, whenever a variety of Heyting algebras has finite depth, then it has surjective epimorphisms. In contrast, we show that (...) for every integer $n \geq 2$ , the variety of all Heyting algebras of width at most n has a non-surjective epimorphism. Within the so-called Kuznetsov-Gerčiu variety (i.e., the variety generated by finite linear sums of one-generated Heyting algebras), we describe exactly the subvarieties that have surjective epimorphisms. This yields new positive examples, and an alternative proof of epimorphism surjectivity for all varieties of Gödel algebras. The results settle natural questions about Beth-style definability for a range of intermediate logics. (shrink)

So Pearson. The strange series of hypodochmiacs here and atO.T.1207 ff., with brevis in longo without pause atAj.421 andO.T.1208, seems metrically self-contained, despite their syntactical interdependence (esp.Aj.421–2οὐκέτ' ἄνδρα μὴ | τόνδ' ἴδητ', so that the word-overlap ofοἷονinto iambics in Pearson's text is unlikely.ἑξερῶ μέγαshould therefore be writtenplena scriptura.

Multiple Sclerosis is a debilitating chronic autoimmune disease of the central nervous system that results in lower quality of life. Medication adherence is important for reducing relapse, disease progression, and MS-related symptoms, particularly during the early stages of MS. However, adherence may be impacted by negative emotional states. Therefore, it is important to identify protective factors. Past research suggests that the ability to discriminate between negative emotional states, also known as negative emotion differentiation, may be protective against enactment of maladaptive (...) risk-related behaviors. However, less is known as to how NED may promote adaptive health behaviors such as medication adherence. Utilizing weekly diaries, we investigated whether NED moderates the association between negative affect and medication adherence rates across 58 weeks among patients newly diagnosed with MS. Results revealed that NED significantly moderated the relationship between negative affect and medication adherence. Specifically, greater negative affect was associated with lower adherence only for individuals reporting low NED. However, this link disappeared for those reporting moderate to high NED. Building upon past research, our findings suggest that NED may promote adaptive health behaviors and have important clinical implications for the treatment and management of chronic illness.

The "Dutch Book" argument, tracing back to Ramsey and to deFinetti, offers prudential grounds for action in conformity with personal probability. Under several structural assumptions about combinations of stakes, your betting policy is coherent only if your fair odds are probabilities. The central question posed here is the following one: Besides providing an operational test of coherent betting, does the "Book" argument also provide for adequate measurement of the agents degrees of beliefs? That is, are an agent's fair odds also (...) his/her personal probabilities for those events? We argue the answer is "No!" The problem is caused by the possibility of state dependent utilities.

In this paper, a survey of 180 inscriptions in Tamil between 1346 CE and 1400 CE is analysed for its notions and visualization of astral themes present in the epigraphical inscriptions as well as for the calendrical practices implicit in those inscriptions. I demonstrate the rich diversity of calendrical practices employed in this period. Although there are clear local usages, the applied methods of identification show that in several cases methods from other Indian calendrical traditions have also been used. This (...) applies both to the year and the month. In contrast, the use of the weekday is not widely seen in the inscriptions of this region following the local system. The study also clarifies that the inscriptions are a useful documentary source for other astronomical observations such as eclipses and solstices undertaken in southern Indian locations in the fourteenth and fifteenth centuries.

Prior research examining mate expulsion indicates that women are more likely to expel a mate due to deficits in emotional access while men are more likely to expel a mate due to deficits in sexual access. Prior research highlights the importance of accounting for measurement limitations (e.g., the use of incremental vs. forced-choice measures) when assessing attitudes toward sexual and emotional infidelity; Wade & Brown, 2012; Sagarin et al., 2012). The present research uses conjoint analysis, a novel methodology for controlling (...) several limitations of using continuous self-report measures in mate expulsion research. Participants (N = 181; 128 women) recruited from Bucknell University and several psychology recruitment listservs in the US rated 9 profiles that varied in three potential levels of emotional and sexual accessibility. Men were more likely to want to break up with a partner due to sexual accessibility deficits, whereas women were more likely to want to break up due to emotional accessibility deficits. However, regardless of sex, emotional inaccessibility was more likely to produce mate expulsion. These findings are consistent with prior theory and highlight the need to disentangle emotional accessibility into its constituent in-pair benefits. This research also illustrates the utility of conjoint analysis as a statistical tool for studying how humans resolve trade-offs among competing outcomes during romantic decision-making. (shrink)

Originally published in 1957, this book collects together large sections of important tracts from a variety of political documents, particularly those concerned with democracy, communism, Protestantism or Catholicism. The extracts come from a wide range of authors including Bertrand Russell, Karl Marx, John Locke and Pope Pius XII. This book will be of value to anyone seeking an overview of the key political divisions in the late 20th century or who is interested in political theory generally.

Hugh of Saint-Victor's De Sacramentis is usually regarded as an early summa of theology. As such it has been regarded as not totally satisfying, lacking a clearness of its conceptual system when compared with the work of e.g. Peter the Lombard. What may make up for this lack of system and even confer coherence, be it on a different level, is Hugh's pedagogical view of creation and salvation history, as it shows most clearly in his tropological digressions. In his exposition (...) of the history of salvation as it unfolds since the very beginning, Hugh incorporates the process by which the monk can not only follow the story of the macrocosm, but at the same time can read his self into being, allowing recognition of ambivalence from the start, and thus presenting a multi-demensional view of being human. In the same way as, on the cosmic level, any pre-lapsarian state of innocence exhibits a flaw from the very beginning, so the life of man is in a permanent state of ambiguity. This ambiguity is the framework for man as a moral being. Only within the possibility of choice can man be just or happy, without choice justus and beatus have no real significance. Matters are shown to be even more complicated when, in the story of Eve Hugh draws attention to her doubtful interpretation of God's command, as a factor which precedes her choice. In this way, De Sacramentis is not only a doctrina in our sense of the content of Christian dogma, but it offers the monk a point to which he can attach and conform his intentio: by bringing his intentio in form with the story about creation and fall and reparation, the reader can in fact effect the necessary reparatio, consisting of knowledge of truth and love of virtue.

Actuality of the conducted research is practically oriented character. Without the use of information and communication technologies in the field of higher education, it is impossible to carry out qualitative training of specialists in engineering, the results of which are necessary for the implementation of a national strategy for modernizing the economy and forming a progressive state of European type. Formulation of the task - the specificity of the use of ICT in the system of higher education has not been (...) studied sufficiently. ICT form a complex environment, which includes a lot of information objects and the links between them. It can be argued that the structural and functional analysis of the use of ICT in higher education is the basis of the theoretical justification in the formation of technical professionalism of future engineers. ICTs form a complex system, which includes not only technical and software-hardware capabilities, but also psycho-pedagogical, organizational, methodological. Without taking into account all of these components, as well as the needs of the subjects of the educational process, the use of ICT tools may be accompanied by risks and negatively affect the quality of high education. An analysis of recent research and publications-is actively exploring the experience of using ICT in high school, it is possible to distinguish the work of foreign specialists D. Stevenson, G. Reinhold, E. Wenger, S. Papierta, I. Zakharova, E. Patarakina, A. Khutorskogo, E. Polat The founders of this scientific direction in our country were M. I. Zhaldak, Y. I.Mashbits. The recent significant increase in the number of studies, the subject of which was the use of information and communication technologies in the educational process. Tsitemi in Ukraine is dedicated to the study of such scholars as V. Yu. Bykov, Ya.V. Bulakhova, O.M. Bondarenko, V.F. Zabolotny, G.O. Kozlakova, O. Moiko, O. Naumenko, Yu.Burovitskaya, I. Stavyts'ka, O.P. Pinchuk, O.V. Shestopal and others. Selection of unexplored parts of the general problem. The use of information technologies in the educational process is the foundation of innovative development of the educational system. The rapid development of ICT provides not only significant pace of innovative progress, but also requires the definition of information resources that guarantee the quality of learning, the choice of techniques that are in line with the general strategy for the formation of professional competences. Therefore, the problem of choosing an approach to the process of learning with the use of ICTs remains one of the main tasks of education. Research methods. In theory and practice, the study of the application of information and communication technologies in high school uses empirical methods of collecting and analyzing information based on the results of the survey of 120 students. Presenting main material. The essence of professionalism of future specialists of the technical direction is revealed. The scientific point of view on the professionalism of the engineer is presented. The peculiarities of formation of the basis of technical professionalism of future engineers in the process of studying at a higher school are theoretically grounded. The quantitative and qualitative analysis of the results of empirical researches of this problem is presented. The practical significance of the research topic is that the innovative approaches to the training of specialists in engineering specialties are differentiated, which differentiate in the educational concepts of teaching in higher educational institutions of European countries.

My chief object in these notes is to provide evidence for tracing the ancestry of certain themes, situations, and characters which appear in New Comedy; I hope, however, that they may also be useful for the study of Middle Comedy itself. I am therefore chiefly concerned with the period from 400 b.c. to 320 b.c., when Menander had begun to write; I have, however, given some dates after 320 which were necessary to complete my story, but I have left out (...) many plays by poets of New Comedy which can be dated in the decade 320–310 b.c. I have also omitted the originals of Plautus Amphitruo, Persa, and Menaechmi, although I am convinced that they all belong to Middle Comedy and hope to consider the problem more fully elsewhere; the tactics of the battle in the Amphitruo are possible for Epameinondas and Philip as well as for Alexander, but the clash of two kings seems to limit the reference to Alexander and Dareios as depicted in the famous mosaic, and the limits are 330–320 ; the original of the Persa must have been written before Alexander's conquests and the limits seem to be 345–338; Hueffher's late dating of the original of the Menaechmi has been successfully countered by Fraenkel and the whole feel of the play suggests Middle rather than New Comedy. The following list is arranged in decades, except where it has proved necessary to use a longer period. I have tabulated first the plays or victories dated by inscriptional or other firm evidence; among these I have included the plays dated by Geissler, without comment except where I disagree with him.
