Amongst Professor Dickens’ extensive writings on medical law and medical jurisprudence are a host of distinguished contributions on the subject of the proper legal and ethical limits on human experimentation. As early as 1975, Professor Dickens was examining the legal aspects of human experimentation. A few years later he was promoting the responsibility of researchers to recognize and protect human rights in medical experimentation. In the last two decades, Professor Dickens has penned a rich flow of scholarly contributions on the legal and ethical rights and duties in medical experimentation and the need to do better as a research community. His articles have considered a broad range of issues in medical experimentation including the imperative of voluntary consent, the ethical unacceptability of co-ercion or inducement of research participants, embryonic research, epidemiological research and the protection of vulnerable research participants, particularly children.

Chapter 1: Two Concepts of Mind. I distinguish the phenomenal and psychological concepts of mind. I argue that every mental state is a phenomenal state, a psychological state, or a hybrid of the two. I discuss the two mind-body problems corresponding to the two concepts of mind, and discuss the various senses of the term “consciousness”. Chapter 2: Supervenience and Explanation. I distinguish varieties of supervenience, especially logical and natural supervenience, where supervening properties covary with base properties across either logically possible or naturally possible worlds. Materialism is the thesis that all positive properties globally metaphysically supervene on microphysical properties. A property is reductively explainable in terms of physical properties if it globally logically supervenes on those properties.

At first glance, the first informed consent case to be decided by the High Court of Australia appears to be little more than a clear and simple description of the substantive law accepted in most American jurisdictions - although that is no small accomplishment in and of itself. In Rogers v. Whitaker, the highest court in Australia succinctly and persuasively rejected informed consent as a species of battery law, accepted it as a form, of ordinary professional negligence law, and adopted the “American” patient-oriented standard for measuring the breach of a healthcare professional's duty to her or his patients. On second look, however, the opinion is an even more significant one because it reveals that the law of informed consent is now based on principles broad enough to create a duty on the part of healthcare providers to offer adequate health education to all of their patients. In Implicitly recognizing the physician's duty to educate her or his patients, the High Court's judgment is consistent with a view increasingly held In the medical and ethical communities that teaching patients about how to maintain their health is just as much a part of the doctor's function as diagnosing and treating disease. It may have taken 2,500 years for medicine to progress from, the Hippocratic notion that physicians should apply treatment to patients who are kept in blissful Ignorance of their condition and Its remedy, but there Is little doubt that medicine finally has entered a post-Hippocratic era

There has been much interest in the possibility of connectionist models whose representations can be endowed with compositional structure, and a variety of such models have been proposed. These models typically use distributed representations that arise from the functional composition of constituent parts. Functional composition and decomposition alone, however, yield only an implementation of classical symbolic theories. This paper explores the possibility of moving beyond implementation by exploiting holistic structure-sensitive operations on distributed representations. An experiment is performed using Pollack’s Recursive Auto-Associative Memory. RAAM is used to construct distributed representations of syntactically structured sentences. A feed-forward network is then trained to operate directly on these representations, modeling syn- tactic transformations of the represented sentences. Successful training and generalization is obtained, demonstrating that the implicit structure present in these representations can be used for a kind of structure-sensitive processing unique to the connectionist domain.
