At the bottom of all human activities are “values,” the conviction that some things “ought to be” and others not. Science, however, with its immense interest in mere facts seems to lack all understanding of such‘requiredness.’… A science … which would seriously admit nothing but indifferent facts … could not fail to destroy itself.

Institutional ethics committees (IECs) are part of a growing phenomenon in the American health care system. Although a major force driving hospitals to establish IECs is the desire to resolve difficult clinical dilemmas in a quick and systematic way, in this paper we argue that such a goal is naive and, to some extent, misguided. We assess the growing trend of these committees, analyse the theoretical assumptions underlying their establishment, and evaluate their strengths and shortcomings. We show how the 'medical (...) consultation' model is often inappropriately applied to IECs and suggest that IECs must operate under a different framework. Finally, we argue that IECs should be valued for the process they facilitate, and not for the product that they are, often unreasonably, expected to deliver. (shrink)

The present study aimed to analyze the stability of the memory of a stressful event (medical examination within a hospital setting) over time in young people (age range 12 to 21, Mage = 15.11 years old, SD = 3.047) with mild or moderate intellectual disability (IQ = 54.32, SD = 13.47). The results show a stability of the memory of what happened an hour and a week after the event in relation to the people involved, the apparatus used, and the (...) parts of the body explored. No interaction effects were found between the stability of memory over time and the level of intellectual disability. The level of disability (mild or moderate) only affected the description of the doctor who performed the exploration and the explored parts of the body, showing better results for people with mild disability. In addition, the results highlight the relationship between memory and IQ, especially verbal IQ. (shrink)

We use a new model of metarepresentational development to predict a cognitive deficit which could explain a crucial component of the social impairment in childhood autism. One of the manifestations of a basic metarepresentational capacity is a ‘ theory of mind ’. We have reason to believe that autistic children lack such a ‘ theory ’. If this were so, then they would be unable to impute beliefs to others and to predict their behaviour. This hypothesis was tested using Wimmer (...) and Perner’s puppet play paradigm. Normal children and those with Down’s syndrome were used as controls for a group of autistic children. Even though the mental age of the autistic children was higher than that of the controls, they alone failed to impute beliefs to others. Thus the dysfunction we have postulated and demonstrated is independent of mental retardation and specific to autism. (shrink)

There are simple mechanical systems that elude causal representation. We describe one that cannot be represented in a single directed acyclic graph. Our case suggests limitations on the use of causal graphs for causal inference and makes salient the point that causal relations among variables depend upon details of causal setups, including values of variables.

BackgroundAdolescents living with human immunodeficiency virus (HIV) experience challenges, including lack of involvement in their care as well nondisclosure of HIV status, which leads to poor adherence to antiretroviral therapy (ART). Parents have authority over their children, but during adolescence there is an increasing desire for independence. The aim of the study was to explore adolescents’ experience of challenges identified by adolescents ages 10–19 years attending HIV care and treatment at Temeke Regional Referral Hospital in Tanzania. MethodsAn exploratory descriptive qualitative (...) design was employed in the HIV Care and Treatment Centre (CTC) in the Out-Patient Department at the Temeke Regional Referral Hospital in Tanzania with adolescents living with HIV who were 10–19 years of age. A total of 22 adolescents participated in semi-structured face-to-face interviews after parental consent and adolescent assent were obtained. Participants were interviewed about their participation in decisions to be tested for HIV and enrolled in the CTC, concerns surrounding disclosure of their HIV status to the adolescent or to others, stigma and discrimination, and the effect of these challenges on their adherence to medication. All interviews were audio-taped, transcribed verbatim in Swahili, and back-translated to English. Data analysis included both inductive and deductive thematic analysis.ResultsQualitative themes identified included lack of participation in decisions about HIV testing, challenges to enrollment in care and treatment; issues around disclosure of HIV status, such as delays in disclosure to the adolescent and disclosure to other persons and benefits and harms of such disclosures; and factors supporting and interfering with adherence to ART, such as parental support, organizational (clinic) support and problems, and self-stigmatization and shame.ConclusionLack of adolescents’ involvement in their care decision making and delayed disclosure of HIV status to the adolescent were identified concerns, leading to poor adherence to ART among adolescents. Disclosure to others, especially teachers, helped adolescents at school to take their medication properly. Disclosure to others led to stigma and discrimination for some adolescents. More research is needed to better understand the role of disclosure and its benefits and challenges for HIV-positive adolescents in Tanzania. (shrink)

In this paper we review the evolution of the concept of “ vacuum ” according to different theories formulated in the last century, like Quantum Mechanics, Quantum Electrodynamics, Quantum Chromodynamics in Particle Physics and Cosmology. In all these theories a metastable vacuum state is considered which transforms from one state to another according to the energy taken into consideration. It is a “fluid” made up by matter and radiation present in the whole Universe, which may be identified with a modern (...) definition of ether. (shrink)

This article examines how the action logics associated with the stages of consciousness development of organizational leaders can influence the meaning, which these leaders give to corporate greening and their capacity to consider the specific complexities, values, and demands of environmental issues. The article explores how the seven principal action logics identified by Rooke and Torbert (2005, Harvard Business Review 83 (4), 66–76; Opportunist, Diplomat, Expert, Achiever, Individualist, Strategist and Alchemist) can affect environmental leadership. An examination of the strengths and (...) limitations of these action logics reveals the relevance of the so-called post-conventional stages of consciousness to the recognition and effective management of complex environmental issues. Suggestions are also made for promoting organizational contexts conducive to the development of a post-conventional environmental leadership. (shrink)

This study investigated grammatical gender processing in school-age Spanish-English bilingual children using a visual world paradigm with a 4-picture display where the target noun was heard with a gendered article that was either in a context where all distractor images were the same gender as the target noun or in a context where all distractor images were the opposite gender than the target noun. We investigated 32 bilingual children who were exposed to Spanish since infancy and began learning English by (...) school entry. Along with the eye-tracking experiment, all children participated in a standardized language assessment and told narratives in English and Spanish, and parents reported on their child's current Spanish language use. The differential proportion fixations to target were analyzed in two time regions with linear mixed-effects models. Results show that prior to the target word being spoken, these bilingual children did not use the gendered articles to actively anticipate upcoming nouns. In the subsequent time region, it was shown that there are differences in the way they use feminine and masculine articles, with a lack of use of the masculine article and a potential facilitatory use of the feminine article for children who currently use more Spanish than English. This asymmetry in the use of gendered articles in processing is modulated by current Spanish language use and trends with results found for bilingual and second-language learning adults. (shrink)

De Dreu and Gross's distinction between attack and defense is complicated in real-world conflicts because competing leaders construe their position as one of defense, and power imbalances place status quo challengers in a defensive position. Their account of defense as vigilant avoidance is incomplete because it avoids a reference to anger which transforms anxious avoidance into collective and unified action.

Richard M. Hare (1919 - 2002) is usually acknowledged to be one of the major moral thinkers of the 20th century. After being a Japanese prisoner of war for most of World War II, he completed his education at Oxford, later joining the faculty and becoming a professor. In 1983 he moved to the University of Florida but still kept his ties with Oxford. He had many students, including Peter Singer. At a memorial service for Hare in 2002, Singer ascribed (...) to him three major achievements in moral philosophy, namely “restoring reason to moral argument, distinguishing intuitive and critical levels of moral thinking, and pioneering the development of practical or applied ethics”.

Being able to discriminate poorly justified from well justified arguments is necessary for informed citizenship. However, it is not known whether the ability to recognize argument strength generalizes across different types of arguments, and what cognitive factors predict this ability or these abilities. Drawing on the theory of argument schemes, we examined arguments from consequence, analogy, symptoms, and authority in order to cover all major types of arguments. A study (_N_ = 278) on the general population in Finland indicated that (...) the ability to discriminate between strong and weak arguments did not differ between these schemes. Argument strength discrimination ability correlated positively with analytic thinking dispositions promoting both quality and quantity of thinking, slightly positively with education, and negatively with overconfidence. It was unrelated to an intuitive thinking style, and to self-rated mental effort. (shrink)

In my article on proof [Philosophia Mathematica (3) 5 (1997), 153—165], I suggested or intimated that computer proofs of mathematical theorems had been found only for relatively simple or trivial theorems. I am obligated to Martin Davis and R. S. Boyer for the information that this suggestion or intimation is incorrect. For instance, a machine proof of quadratic reciprocity was published by D. M. Russinoff in J. Automated Reasoning 8 (1992), 3–21. A machine proof of the unsolvability of the halting (...) problem has been published by R S. Boyer and J. S. Moore.

In his famous Crisis of the Early Italian Renaissance Hans Baron treated the Dominican political thinker Ptolemy of Lucca as purely medieval, his ideas totally separate from the doctrine that Baron named civic humanism. However, in an unpublished, and previously-unstudied, manuscript written more than a decade earlier, Baron maintained that Ptolemy's ideology evolved into something quite close to civic humanism. He attempted to prove this through a comparison of early and late work of Ptolemy and through an (...) analysis of Ptolemy's process of composition of his De Regimine Principum. This article analyses Baron's arguments and in general supports them, with some qualifications. Baron's manuscript supports the conclusions previously published by Blythe and is also significant in what it reveals about the intellectual evolution of one of the twentieth century's most significant historians of political thought.
