This article reflects on the subject of abduction. What it is?, what are its components and which role it plays in processes of discovering, particularly scientific discovering.

Se presenta un esquema clasificatorio para la abducción, tomando como criterio a ese fin el tipo de variables intervinientes en el fenómeno, los niveles de matrices de datos que relaciona, la concepción de tiempo implicada, la clase de descripción utilizada, la referencia al contexto, las categorías..

This article asked for the nexus that unites the scientific research with criminology investigation and the aspects that separate them. From this basic premise, it sets out like central objective, to describe similarities and differences between both classes of investigation, with special emphasis..

The language of science goes from description ton explanation; the first one is concerned in telling how phenomena happen and the second one to tell why they happen. This article explores two postures within science: the descriptive and the explanatory.

The present work intends to investigate about explanation models related to the evolution concept in school texts in Argentina, using categories proposed by Bar (2005). The reconstructed model shows characteristics of adaptation systems, models that give account of biological phenomena with end..

En este artículo se revisan los conceptos principales de la metodología cuantitativa, considerando el contexto histórico de la ciencia en Latino América y se presentan las áreas del conocimiento que se nutren de estudios de tipo cuantitativo en Latino América en revistas de investigación.In this essay it is reviewed the main concepts of quantitative methodology, considering the historical context of science in Latin America and it is showed the areas of knowledge that use quantitative studies in Latin American in journals.

This essay pretends to bring to discussion some ideas for the clearing of the concept of measurement, and, from there, to the discussion of the nature of variables and their scales.

Social Research can be made both from an analytical conception or from a systemic conception. In the first, the system is divisible in its parts, which keep the properties of the system. In the second, the system constitutes a hole which cannot be re-constituted from the properties of the mere sub-..

Science education is generally perceived as a key facilitator in cultivating a scientifically literate society. In the last decade, however, this conventional wisdom has been challenged by evidence that greater scientific literacy and critical thinking skills may in fact inadvertently aggravate polarization on scientific matters in the public sphere. Supporting an alternative “scientific update hypothesis,” in a series of studies (total N = 2087), we show that increased science’s epistemology literacy might have consequential population-level effects on the public’s alignment with (...) scientific results. In one exploratory study and a pre-registered national online survey, we first show that understanding scientific epistemology predicts refusal of pseudoscientific beliefs and higher scores in a methodology of science test. We also find and replicate a propensity for epistemologically literate citizens to endorse the norm of belief updating and the communicated scientific consensus following both ideologically congruent and incongruent scientific results. Notably, after 2 months of first being presented with scientific results on politically controversial issues, a one standard deviation higher score in epistemological literacy is associated with a 14% increase in the odds of individuals switching their beliefs to align with the scientifically communicated consensus. We close by discussing how, on the face of ideological incongruity, a general understanding of scientific epistemology might foster the acceptance of scientific results, and we underscore the need for a more nuanced appreciation of how education, public comprehension of scientific knowledge, and the dynamics of polarization intersect in the public sphere.

This book highlights some of the most pressing safety, ethical, legal and societal issues related to the diverse contexts in which robotic technologies apply. Focusing on the essential concept of well-being, it addresses topics that are fundamental not only for research, but also for industry and end-users, discussing the challenges in a wide variety of applications, including domestic robots, autonomous manufacturing, personal care robots and drones.

Bioethicists involved in end‐of‐life debates routinely distinguish between ‘killing’ and ‘letting die’. Meanwhile, previous work in cognitive science has revealed that when people characterize behaviour as either actively ‘doing’ or passively ‘allowing’, they do so not purely on descriptive grounds, but also as a function of the behaviour’s perceived morality. In the present report, we extend this line of research by examining how medical students and professionals (N = 184) and laypeople (N = 122) describe physicians’ behaviour in end‐of‐life scenarios. (...) We show that the distinction between ‘ending’ a patient’s life and ‘allowing’ it to end arises from morally motivated causal selection. That is, when a patient wishes to die, her illness is treated as the cause of death and the doctor is seen as merely allowing her life to end. In contrast, when a patient does not wish to die, the doctor’s behaviour is treated as the cause of death and, consequently, the doctor is described as ending the patient’s life. This effect emerged regardless of whether the doctor’s behaviour was omissive (as in withholding treatment) or commissive (as in applying a lethal injection). In other words, patient consent shapes causal selection in end‐of‐life situations, and in turn determines whether physicians are seen as ‘killing’ patients, or merely as ‘enabling’ their death.

We study and compare two combinatorial lowness notions: strong jump-traceability and well-approximability of the jump, by strengthening the notion of jump-traceability and super-lowness for sets of natural numbers. A computable non-decreasing unbounded function h is called an order function. Informally, a set A is strongly jump-traceable if for each order function h, for each input e one may effectively enumerate a set Te of possible values for the jump JA, and the number of values enumerated is at most h. A′ (...) is well-approximable if can be effectively approximated with less than h changes at input x, for each order function h. We prove that there is a strongly jump-traceable set which is not computable, and that if A′ is well-approximable then A is strongly jump-traceable. For r.e. sets, the converse holds as well. We characterize jump-traceability and strong jump-traceability in terms of Kolmogorov complexity. We also investigate other properties of these lowness properties. (shrink)

We consider the question of randomness of the probability ΩU[X] that an optimal Turing machine U halts and outputs a string in a fixed set X. The main results are as follows: ΩU[X] is random whenever X is $\Sigma _{n}^{0}$-complete or $\Pi _{n}^{0}$-complete for some n ≥ 2. However, for n ≥ 2, ΩU[X] is not n-random when X is $\Sigma _{n}^{0}$ or $\Pi _{n}^{0}$ Nevertheless, there exists $\Delta _{n+1}^{0}$ sets such that ΩU[X] is n-random. There are $\Delta _{2}^{0}$ sets (...) X such that ΩU[X] is rational. Also, for every n ≥ 1, there exists a set X which is $\Delta _{n+1}^{0}$ and $\Sigma _{n}^{0}$-hard such that ΩU[X] is not random. We also look at the range of ΩU as an operator. We prove that the set {ΩU[X]: X ⊆ 2<ω} is a finite union of closed intervals. It follows that for any optimal machine U and any sufficiently small real r, there is a set X ⊆ 2<ω recursive in ∅′ ⊕ r, such that ΩU[X] = r. The same questions are also considered in the context of infinite computations, and lead to similar results. (shrink)

This paper investigates indifferent sets for comeager classes in Cantor space focusing of the class of all 1-generic sets and the class of all weakly 1-generic sets. Jockusch and Posner showed that there exist 1-generic sets that have indifferent sets [10]. Figueira, Miller and Nies have studied indifferent sets for randomness and other notions [7]. We show that any comeager class in Cantor space contains a comeager class with a universal indifferent set. A forcing construction is used to show that (...) any 1-generic set, or weakly 1-generic set, has an indifferent set. Such an indifferent set can by computed by any set in GL2 which bounds the (weakly) 1-generic. We show by approximation arguments that some, but not all, ∆0 1-generic sets can compute an indifferent set 2 for themselves. We show that all ∆0 weakly 1-generic sets can compute 2 an indifferent set for themselves. Additional results on indifferent sets, including one of Miller, and two of Fitzgerald, are presented.

Did Plato abandon, or sharply modify, the Theory of Forms in later life? In the Phaedo, Symposium, and Republic it is generally agreed that Plato held that universals exist. But in Parmenides, he subjected that theory to criticism. If the criticism were valid, and Plato knew so, then the Parmenides marks a turning point in his thought. If, however, Plato became aware that there are radical differences in the logical behaviour of concepts, and the later dialogues are a record of (...) his attempt to analyse those differences, then Plato’s thought can be said to have moved in a new and vitally important direction after the Parmenides . Studies in Plato’s Metaphysics brings together twenty essays by leading philosophers from the UK and the USA reflecting upon this important issue and upon the questions arising from it. (shrink)

It has been reported that, on average, most adults recall first memories formed around age 3.5. In general, most first memories are positive. However, whether these first memories tend to be visual or verbal and whether the period for childhood amnesia (CA) is greater for visual or verbal or for positive versus negative memories has not been determined. Because negative, stressful experiences disrupt memory and can injure memory centers such as the hippocampus and amygdala, and since adults who were traumatized (...) or abused during childhood (TA) reportedly suffer memory disturbances, it was hypothesized that those with a history of early trauma might suffer from a lengthier childhood amnesia and form their first recallable memories at a later age as compared to the general population (GP). Because the right hemisphere matures earlier than the language-dominant left hemisphere, and is dominant for visual and emotional memory, as well as the stress reponse, it was hypothesized that first recallable memories would be visual rather than verbal. Lastly, since stress can injure the brain and disrupt memory, it was hypothesized that the traumatized group would demonstrate memory and intellectual disturbances associated with right hemisphere injury as based on WAIS-R, Wechsler Memory Scale, and facial-memory testing. All hypotheses were supported. Positive and visual memories are formed before negative and verbal memories. TA CA offset, on average, is at age 6.1 versus 3.5 for GPs. TA PIQ (performance IQ), short-term visual memory, and facial memory were significantly reduced. (shrink)

J. Krishnamurti (1895-1986) was thought by many to be a modern-day equivalent of the Buddha. In fact, he was once even considered to be the second coming of Christ. While many think it wonderful to live and work in close proximity with such a person, it's difficult to understand the depth of what this means and how challenging this might be. In Knocking at the Open Door, author R.E. Mark Lee provides an ordinary person view of what being close-up and (...) working together with such a man means, how it challenges one at every turn, and how it causes one to question ceaselessly, even more deeply than one ordinarily would. Lee offers an insightful, candid, and heartfelt narrative that reveals various unknown facets of the eminent world teacher J. Krishnamurti and highlights his distinctive vision for education worldwide. This comprehensive volume brings alive the practical and everyday interactions Lee had with Krishnamurti during a twenty-year period in India and the United Sates. Knocking at the Open Door shares a clear and honest account that demonstrates the challenges of working with Krishnamurti in running a school that is true to the teaching and yet able to function in the reality of modern parental, student, and educational establishment expectations.

This paper attempts to explore a number of conceptual issues surrounding genetic testing. It looks at the meaning of the terms, genetic information and genetic testing in relation to the definition set out by the Advisory Committee on Genetic Testing in the UK, and by the Task Force on Genetic Testing in the USA. It argues that the special arrangements that may be required for the regulation of genetic tests should not be determined by reference to the nature or technology (...) of the test, but by considering those morally relevant features that justify regulation. Failure to do so will lead to the regulation of genetic tests that need not be regulated, and would fail to cover other tests which should be regulated. The paper also argues that there is little in the nature of the properties of gene tests, using DNA or chromosomes, that in itself justifies a special approach. (shrink)

The article studies two related issues. First, it introduces the notion of the contraposition of quantifiers which is a “dual” notion of symmetry and has similar relations to co-intersectivity as symmetry has to intersectivity. Second, it shows how symmetry and contraposition can be generalised to higher order type quantifiers, while preserving their relations with other notions from generalized quantifiers theory.

The Practice of Value is an exploration of a pervasive but puzzling aspect of our world: value. The starting-point is the Berkeley Tanner Lectures delivered in 2001 by the leading moral theorist Joseph Raz. His aim is to make sense of the dependence of value on social practice, without falling back on cultural relativism. The lectures are followed by discussions from three eminent philosophers, Christine Korsgaard, Robert Pippin, and Bernard Williams, and a response from Raz. The result is a fascinating (...) debate, accessible to readers throughout and beyond philosophy, about the relations between human values and human life. (shrink)
