Participants were asked to draw inferences about correlation from single x,y observations. In Experiment 1 statistically sophisticated participants were given the univariate characteristics of distributions of x and y and asked to infer whether a single x, y observation came from a correlated or an uncorrelated population. In Experiment 2, students with a variety of statistical backgrounds assigned posterior probabilities to five possible populations based on single x, y observations, again given knowledge of the univariate statistics. In Experiment 3, statistically (...) naïve participants were given a problem analogous to that given in Experiment 1, framed verbally. Experiment 4 replicated Experiment 3 but added an “impossible to determine” response option. Models that rely on computing sample correlations make no predictions about these investigations. From a Bayesian perspective, participants’ inferences in all four experiments tended to make probabilistically valid inferences as long as the single datum was directional. The results are discussed in light of the Brunswikian notion of vicarious functioning. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:DOES GOD HAVE A QUIDDITY ACCORDING TO AVICENNA* IN THE NEW critical edition of Avicenna's MemphyS'ics by S. Van Riet at Louvain (I, 1977; II, 1980; III, 1983), Gerard Verbeke states that according to Avicenna, "L'Etre necessaire n'a pas une essence qui est distincte de son existence" (II, p. * 42, at note 159), i.e. that the Necessary Being does not have an essence that is distinct from its (...) existence. One looks in vain for a precise reference to an Avicennian text. On the other hand, in a three-part study, Albert G. Judy, O.P., "Avicenna's Me1taphy8'ics in the Summa contra Gentiles," published in Angelicum, part I: 52 (1975) 340-384; part II: 541-586; part Ill: 53 (1976) 183-226, states quite clearly that the "First" does not have a quiddity but only an "anity" (anitas)... (546), and that Avicenna... finds that the absolutely necessary being cannot have what every other reality has, namely, a quiddity, a "whatness " distinct from its" whether-ness" or anitas (547-548). Moreover, the first appendix of Judy's article contains a redaction of the 1495 and the 1508 Venice editions of ltletaphyiscs 8.4, which differs chiefly in punctuation from the excellent Van Riet text based on five Latin MSS. A slightly more nuanced position is. found in Etienne Gilson's Elements of Christian Philosoph;y (Garden City, N. Y.: Doubleday, 1960), p. 127: "... such exactly had been the con- * Delivered before the Society for the Study of Islamic Philosophy and Science meeting in conjunction with The American Catholic Philosophical Association in Milwaukee, Wisconsin, on April 12, 1985. 79 80 E. M. MACIEROWSKI clusion of Avicenna: the first has no quiddity (quidditatem non habet)," a claim that cites (305, note 28) secondary literature which one can trace as far back as Father M.-D. RolandGosselin 's edition of the De ente et essentia. What is at stake in this dispute? What if God does not have a quiddity? It would seem that He should be utterly unknowable, if quiddity or essence is a principle of knowledge as well as of being. Such would be plausible consequences of Gilson's and Judy's position. What, on the other hand, if God does have a quiddity? One possible inference, if we happened to have access or insight into the divine quiddity, is that we could have a sort of mystical union with God, perhaps even in this life; or again, one might draw pantheistic conclusions. Verbeke does not follow such paths. His inference points toward a rawrochement between Avicenna's doctrine and that of St. Thomas Aquinas, who maintained not only that God is His own essence (and therefore that it is reasonable to speak of a divine essence) but also that God's essence is no other than His esse, His being or existence. Accordingly, for scholars to have such opposed views about so important a topic even at the hermeneutical level of Avicenna's position points to a serious difficulty. Since Judy does offer texts in support of his interpretation, let us consider the evidence, using his section numbers and Van Riet's pages and lines: Judy, section 4=Van Riet 398.83-399.84 goes thus in Latin: Redibo igitur et dicam quod primum non habet quidditatem, nisi anitatem, quae sit discreta ab ipsa. This text he renders, "The first does not have a quiddity, except an 'anity,' which is distinct from it" (549). The other text in Latin (Judy, section 13=Van Riet 401.31-32) goes thus: Igitur necesse esse non habet quidditatem nisi quod est necesse esse, et haec est anitas, which he renders, "Therefore necessary being does not have a quiddity, but only the fact of its necessary being, and this is DOES GOD HAVE A QUIDDITY ACCORDING TO AVICENNA 81 'anity'" (559). We wonder, however, why nisi should be translated "except" in section 4 and "hut only" in section 13. One would have expected a sed solum or a sed tantum to justify the rendering "but only." Accordingly, the translation should be corrected to read, " Therefore the necessary being has no quiddity except that it is necessary being, and this... (shrink)

This article examines the (bio) ethical and professionalism issues that may arise in the context of medical practice in low and middle income countries (LAMIC), and the challenges this poses for medical regulatory bodies in the regions, in upholding ethics in professional practice. A quadrangle of source of the problems given rise to the breach of ethics in medical practice is identified, and suggested steps, based on ethical principles and concept, is proposed towards the resolution of the problems presented. As (...) LAMIC progress to improve the health of its population, this endeavour should occur hand in hand with contemporary medical ethics theories, taking in context the region’s ethnographic and cultural beliefs and practices.

The harmful impact of an adverse event ripples beyond injured patients and their families to affect physicians, nurses, and other health care staff that are involved. These “Second Victims” may experience intense feelings of anxiety, guilt, and fear. They may doubt their clinical competence or ability to continue working at all. Some go on to suffer post-traumatic stress disorder and depression.Medical institutions long ignored this problem, preferring to believe that adverse events, or “errors,” occur due to incompetence — the unfortunate (...) work of a few “bad” practitioners who deserve, if anything, a reprimand for their negligence. Study after study has rejected this attribution and shown that adverse events in health care stem primarily from systemic flaws, not “bad apples.” Devastating errors, in other words, can, do, and always will happen in the care of competent, well-trained, and caring practitioners.

The avocado (Persea americana) is a major crop commodity worldwide. Moreover, avocado, a paleopolyploid, is an evolutionary “outpost” among flowering plants, representing a basal lineage (the magnoliid clade) near the origin of the flowering plants themselves. Following centuries of selective breeding, avocado germplasm has been characterized at the level of microsatellite and RFLP markers. Nonetheless, little is known beyond these general diversity estimates, and much work remains to be done to develop avocado as a major subtropical‐zone crop. Among the goals (...) of avocado improvement are to develop varieties with fruit that will “store” better on the tree, show uniform ripening and have better post‐harvest storage. Avocado transcriptome sequencing, genome mapping and partial genomic sequencing will represent a major step toward the goal of sequencing the entire avocado genome, which is expected to aid in improving avocado varieties and production, as well as understanding the evolution of flowers from non‐flowering seed plants (gymnosperms). Additionally, continued evolutionary and other comparative studies of flower and fruit development in different avocado strains can be accomplished at the gene expression level, including in comparison with avocado relatives, and these should provide important insights into the genetic regulation of fruit development in basal angiosperms.

This paper challenges the traditional assumption that descriptive and prescriptive sciences are essentially distinct by presenting a study on the implicit normativity of the production and presentation of biomedical scientific facts within evidence-based medicine. This interdisciplinary study serves as an illustration of the potential worth of the concept of implicit normativity for bioethics in general and for integrated empirical ethics research in particular. It demonstrates how both the production and presentation of scientific information in an evidence-based decision-support contain implicit presuppositions (...) and values, which pre-structure the moral environment of the clinical process of decision-making. As a consequence, the evidence-based decision support did not only support the clinical decision-making process; it also transformed it in a morally significant way. This phenomenon undermines the assumption within much of the literature on patient autonomy that information disclosure is a conditional requirement before patient autonomy even starts; patient autonomy is already influenced during the production and presentation of information. These results imply an increased responsibility of those who produce and present evidence-based facts(i.e. scientists in general and physicians in particular). The insights of this study not only involve a different focus on both theory and practice of patient autonomy and informed consent, but they also call for a broader scope of morality than does traditional empirical research in bioethics. The concept of implicit normativity within integrated empirical ethics research calls for a strong cooperation between bioethicists and descriptive scientists, i.e., a cooperation that goes beyond the discipline-specific epistemic values and that takes place during all phases of the research process.

PurposeTo use the power of knowledge acquisition and machine learning in the development of a collaborative computer classification system based on the features of age-related macular degeneration (AMD).MethodsA vocabulary was acquired from four AMD experts who examined 100 ophthalmoscopic images. The vocabulary was analyzed, hierarchically structured, and incorporated into a collaborative computer classification system called IDOCS. Using this system, three of the experts examined images from a second set of digital images compiled from more than 1000 patients with AMD. Images (...) were annotated, and features were identified and defined. Decision trees, a machine learning method, were trained on the data collected and used to extract patterns. Interrelationships between the data from the different clinicians were investigated.ResultsSix drusen classes in the structured vocabulary were largely sufficient to describe all the identified features. The decision trees classified the data with 76.86% to 88.5% accuracy and distilled patterns in the form of hierarchical trees composed of 5 to 15 nodes. Experts were largely consistent in their characterization of soft, and to a lesser extent, hard drusen, but diverge in definition of other drusen. Size and crystalline morphology were the main determinants of drusen type across all experts.ConclusionsMachine learning is a powerful tool for the characterization of disease phenotypes. The creation of a defined feature set for AMD will facilitate the development of an IDOCS-based classification system. (shrink)

Physicists regularly invoke universal laws, such as those of motion and electromagnetism, to explain events. Biological and medical scientists have no such laws. How then do they acquire a reliable body of knowledge about biological organisms and human disease? One way is by repeatedly returning to, manipulating, observing, interpreting, and reinterpreting certain subjects—such as flies, mice, worms, or microbes—or, as they are known in biology, “model systems.” Across the natural and social sciences, other disciplinary fields have developed canonical examples that (...) have played a role comparable to that of biology’s model systems, serving not only as points of reference and illustrations of general principles or values but also as sites of continued investigation and reinterpretation. The essays in this collection assess the scope and function of model objects in domains as diverse as biology, geology, and history, attending to differences between fields as well as to epistemological commonalities. Contributors examine the role of the fruit fly Drosophila and nematode worms in biology, troops of baboons in primatology, box and digital simulations of the movement of the earth’s crust in geology, and meteorological models in climatology. They analyze the intensive study of the prisoner’s dilemma in game theory, ritual in anthropology, the individual case in psychoanalytic research, and Athenian democracy in political theory. The contributors illuminate the processes through which particular organisms, cases, materials, or narratives become foundational to their fields, and they examine how these foundational exemplars—from the fruit fly to Freud’s Dora—shape the knowledge produced within their disciplines.

Background: There is evidence that household point-of-use water treatment products can reduce the enormous burden of water-borne illness. Nevertheless, adoption among the global poor is very low, and little evidence exists on why. Methods: We gave 600 households in poor communities in Dhaka, Bangladesh randomly-ordered two-month free trials of four water treatment products: dilute liquid chlorine, sodium dichloroisocyanurate tablets, a combined flocculant-disinfectant powdered mixture, and a silver-coated ceramic siphon filter. Consumers also received education on the dangers of untreated drinking water. (...) We measured which products consumers used with self-reports, observation, and chlorine tests. We also measured drinking water's contamination with E. coli. Findings: Households reported highest usage of the filter, although no product had even 30% usage. E. coli concentrations in stored drinking water were generally lowest when households had Water Guard. Households that self-reported product usage had large reductions in E. coli concentrations with any product as compared to controls. Conclusion: Traditional arguments for the low adoption of POU products focus on affordability, consumers' lack of information about germs and the dangers of unsafe water, and specific products not meshing with a household's preferences. In this study we provided free trials, repeated informational messages explaining the dangers of untreated water, and a variety of product designs. The low usage of all products despite such efforts makes clear that important barriers exist beyond cost, information, and variation among these four product designs. Without a better understanding of the choices and aspirations of the target end-users, household-based water treatment is unlikely to reduce morbidity and mortality substantially in urban Bangladesh and similar populations. © 2011 Luoto et al.

The earlier volume in this series dealt with two religions of Indian origin, namely, Buddhism and Jainism. The Indian religious scene, however, is characterized by not only religions which originated in India but also by religions which entered India from outside India and made their home here. Thus religious life in India has been enlivened throughout its history by the presence of religions of foreign origin on its soil almost from the very time they came into existence. This volume covers (...) three such religions—Zoraoastrianism, Judaism, and Islam. In the case of Zoraostianism, even its very beginnings are intertwined with India, as Zoroastrianism reformed a preexisting religion which had strong links to the Vedic heritage of India. This relationship took on a new dimension when a Zoroastrian community, fearing persecution in Persia after its Arab conquest, sought shelter in western India and ultimately went on to produce India’s pioneering nationalist in the figure of Dadabhai Naoroji ( 1825-1917), also known as the Grand Old Man of India. Jews found refuge in south India after the destruction of the Temple by the Romans in 70 C.E. and have remained a part of the Indian religious scene since then, some even returning to Israel after it was founded in 1948. Islam arrived in Kerala as soon as it was founded and one of the earliest mosques in the history of Islam is found in India. Islam differs from the previously mentioned religions inasmuch as it went on to gain political hegemony over parts of the country for considerable periods of time, which meant that its impact on the religious life of the subcontinent has been greater compared to the other religions. It has also meant that Islam has existed in a religiously plural environment in India for a longer period than elsewhere in the world so that not only has Islam left a mark on India, India has also left its mark on it. Indeed all the three religions covered in this volume share this dual feature, that they have profoundly influenced Indian religious life and have also in turn been profoundly influenced by their presence in India.

The Alternative Model of Personality Disorders integrates several theoretical models of personality functioning, including interpersonal theory. The interpersonal circumplex dimensions of warmth and dominance can be conceptualized as traits similar to those in AMPD Criterion B, but interpersonal theory also offers dynamic hypotheses about how these variables that change from moment to moment, which help to operationalize some of the processes alluded to in AMPD Criterion A. In the psychotherapy literature, dynamic interpersonal behaviors are thought to be critical for identifying (...) therapeutic alliance ruptures, yet few studies have examined moment-to-moment interpersonal behaviors that are associated with alliance ruptures at an idiographic level. The current study examined the concurrent and cross-lagged relationships between interpersonal behaviors and alliance ruptures within each session in the famous Gloria films. Interpersonal behaviors as well as alliance ruptures were calculated at half minute intervals for each dyad. We identified distinct interpersonal patterns associated with alliance ruptures for each session: Gloria ’s warmth was positively related with withdrawal ruptures concurrently in the session with Carl Rogers; Gloria’s dominance and coldness were related with increased confrontation ruptures in the session with Fritz Perls concurrently, while her coldness was also predicted by confrontation ruptures at previous moments; lastly, both Gloria’s dominance and Albert Ellis’s submissiveness were positively related with withdrawal ruptures. These interpersonal patterns demonstrated the promise of using AMPD dimensions to conceptualize momentary interpersonal processes related to therapy ruptures, as well as the clinical importance of attuning to repetitive, dyad-specific interpersonal cues of ruptures within each session.

Introduction to the life and work of G.E.M. Anscombe.

Since the time, about a century ago, when DeMorgan, Boole and Jevons, inaugurated the study of the logic of numerically definite reasoning, no one has been concerned to establish the validity rules for a very general type of numerically definite inference which is a strong analogue of the classical syllogism. The reader will readily agree that the traditional rules of syllogistic inference cannot even begin to decide whether the following proportionally quantified syllogism is a valid argument: at most 4/7 p (...) are at most 2/3 not-m and at least 3/5 s are precisely 7/8 m, hence, at most 1/3 s are p. Likely reasons, of broad methodological interest, why this readily definable type of formal inference has been neglected will presently be proposed. Among the masters of twentieth century logic, Hilbert and Bernays have, to be sure, meticulously shown how such numerically definite propositions as “at least 7 individuals have the property p” can be expressed in the predicate calculus with the use of the identity relation. They do not, since their concern with such propositions is indirect, proceed to establish a systematic calculus of classes whose “size” or extent is numerically definite. As we shall always notice, traditional logic and even ordinary Boolean algebra prefer to generalize about the laws governing the interrelationship of classes in inference systems without making any hypotheses concerning class “size” or extent except by the classical quantifier “some”, which quantifier admits the measure or extent of a class only in terms of the proposition that a given class contains or does not contain at least one member. Such a restricted admission of the relevance for inference of class size is among the fundamental reasons for the neglect of proportional quantifiers, i.e., quantifiers where numerical value is any rational number r such that 0/100 ≤ r ≤ 100/100. It can, of course, also be pointed out that the traditional syllogism and ordinary Boolean algebra do not i.e. measure, numerically define, the degree of inclusion of one class in another. Inclusion is taken either as total or partial, with no discrimination of the degree of partial inclusion. (shrink)

Classification learning is a preeminent human ability within the animal kingdom but the key mechanisms of brain networks regulating learning remain mostly elusive. Recent neuroimaging advancements have depicted human brain as a complex graph machinery where brain regions are nodes and coherent activities among them represent the functional connections. While long-term motor memories have been found to alter functional connectivity in the resting human brain, a graph topological investigation of the short-time effects of learning are still not widely investigated. For (...) instance, classification learning is known to orchestrate rapid modulation of diverse memory systems like short-term and visual working memories but how the brain functional connectome accommodates such modulations is unclear. We used publicly available repositories (openfmri.org) selecting three experiments, two focused on short-term classification learning along two consecutive runs where learning was promoted by trial-by-trial feedback errors, while a further experiment was used as supplementary control. We analyzed the functional connectivity extracted from BOLD fMRI signals, and estimated the graph information processing in the cerebral networks. The information processing capability, characterized by complex network statistics, significantly improved over runs, together with the subject classification accuracy. Instead, null-learning experiments, where feedbacks came with poor consistency, did not provoke any significant change in the functional connectivity over runs. We propose that learning induces fast modifications in the overall brain network dynamics, definitely ameliorating the short-term potential of the brain to process and integrate information, a dynamic consistently orchestrated by modulations of the functional connections among specific brain regions.
