In this paper, I compare the extent of Anglo-American judicial engagement in response to civil disobedience with that of the French judiciary. I begin by examining what the civil disobedient can realistically expect to achieve in a court of law. I shall argue that his priority should be to require the judge, acting as a mouthpiece for the law, to respond to his complaints. To do this, the civil disobedient must be able to deny liability for the offence he has allegedly committed by urging a different interpretation of the law on the basis of an alternative -- but plausible -- reading of constitutional or human rights. If the civil disobedient can do this, he can claim a victory of sorts, even if his claims are ultimately unsuccessful. But legal culture can present a further barrier. Judges have different roles in different jurisdictions and therein lie further difficulties for the French civil disobedient.  相似文献

Science and Human Behavior was translated to Portuguese as part of the effort to begin a psychology course at the University of Brasília 40 years ago; one of the many results of the first visit of Fred S. Keller to Brazil. The book has been used continuously in undergraduate courses in Brazil since 1967.  相似文献

The advent of neuroimaging methods such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) has provided investigators with a tool to study neuronal processes involved in cognitive functions in humans. Recent years have seen an increasing amount of studies which mapped higher cognitive functions to specific brain regions. These studies have had a great impact on our understanding of neuroanatomical correlates of learning and memory in the living human brain. Recently, advances were made to go beyond the use of fMRI as a pure cognitive brain mapping device. One of these advances includes the use of psychopharmacological approaches in conjunction with neuroimaging. The paper will introduce the combination of neuroimaging and psychopharmacology as a tool to study neurochemical modulation of human brain function. A review of imaging studies using cholinergic challenges in the context of explicit and implicit learning and memory paradigms is provided which show that cholinergic neurotransmission modulates task-related activity in sensory and frontal cortical brain areas.  相似文献

Margaret Mohrmann, Paul Lauritzen, and Sumner Twiss raise questions about my account of basic interests, liberal theory, and the challenges of multiculturalism as developed in Children, Ethics, and Modern Medicine. Their questions point to foundational issues regarding the justification and limitation of parental authority to make decisions on behalf of children in medical and other contexts. One of the central questions in that regard is whether adults' decisions deserve to be respected, especially when they seem contrary to a child's or adolescent's basic interests. Questions about respect, in turn, focus attention on other's decisions about what seems good for families and children, decisions that may be paternalistic or utilitarian. Such decisions are further complicated by a child's or adolescent's budding autonomy and need for respect and recognition. Pediatric bioethics grounded in an account of a child's basic interests produces a theory of negative and positive rights for assessing adults' actions in relation to children, especially (but not only) when adults demand respect in their expressions of care.  相似文献

This longitudinal study of the effects of iron deficiency in infancy assessed motor development over time in 185 healthy Costa Rican children who varied in iron status at 12-23 months. Longitudinal analyses (hierarchical linear modeling) used the Bayley Psychomotor Index before and both 1 week and 3 months after iron treatment in infancy and the Bruninks-Oseretsky Test of Motor Proficiency - long form at 5 years and short form at 11-14 years. Children with chronic severe iron deficiency in infancy had lower motor scores at the beginning of the study and a lower but parallel trajectory for motor scores through early adolescence. Thus, there was no evidence of catch-up in motor development, despite iron therapy in infancy that corrected iron deficiency anemia in all cases.  相似文献

In the debate regarding the moral status of human embryos, the Embryo Rescue Case has been used to suggest that embryos are not rightholders. This case is premised on the idea that in a situation where one has a choice between saving some number of embryos or a child, it seems wrong to save the embryos and not the child. If so, it seems that embryos cannot be rightholders. In this paper, I argue that the Embryo Rescue Case does not independently show that embryos are not rightholders.  相似文献

Why are some words easier to learn than others? And what enables the eventual learning of the more difficult words? These questions were addressed for nouns using a paradigm in which adults were exposed to naturalistic maternal input that was manipulated to simulate access to several different information sources, both alone and in combination: observation of the extralinguistic contexts in which the target word was used, the words that co‐occurred with the target word, and the target word's syntactic context. Words that were not accurately identified from observation alone were both abstract (e.g., music) and concrete (e.g., tail). Whether a noun could be learned from observation depended on whether it labeled a basic‐level object category (BLOC). However, the difference between BLOC labels and non‐BLOC labels was eliminated when observation was supplemented with linguistic context. Thus, although BLOC labels can be learned from observation alone, non‐BLOC labels require richer linguistic context. These findings support a model of vocabulary growth in which an important role is played by changes in the information to which learners have access.  相似文献

Jürgen Habermas’s discourse-theoretic reconstruction of the normative foundations of democracy assumes the formal separation of democratic political practice from the economic system. Democratic autonomy presupposes a vital public sphere protected by a complex schedule of individual rights. These rights are supposed to secure the formal and material conditions for democratic freedom. However, because Habermas argues that the economy must be left to function according to endogenous market dynamics, he accepts as a condition of democracy (the formal separation of spheres) a social structure that is in fact anti-democratic. The value of self-determination that Habermas’s theory of democracy presupposes is contradicted by the actual operations of capitalist markets. Further democratic development demands that the steering mechanisms of the capitalist market be challenged by self-organizing civic movements.  相似文献

In a differential human fear conditioning paradigm evidence for ABA-renewal was obtained manipulating the lighting in the experimental room. During acquisition in either a dark or illuminated room, one neutral slide was sometimes paired with a loud aversive noise whereas another slide was not. Subsequently, extinction took place in the opposite lighting context. When afterwards the participants were tested again in the original acquisition context, measurements revealed a recovery of the conditioned electrodermal response and an increase in the retrospective verbal US-expectancy ratings. No response recovery was obtained in an AAA-group that received acquisition, extinction and test trials in one and the same context. Several theoretical explanations for this type of return of fear as well as implications for clinical practice are discussed.  相似文献
