Developmental cognitive neuroscience: progress and potential

Developmental cognitive neuroscience is an evolving field that investigates the relations between neural and cognitive development. Lying at the intersection of diverse disciplines, work in this area promises to shed light on classic developmental questions, mechanisms subserving developmental change, diagnosis and treatment of developmental disorders, and cognitive and neuroscientific topics traditionally considered outside the domain of development. Fundamental questions include: What are the interrelations between developmental changes in the brain (e.g. in connectivity, chemistry, morphology) and developmental changes in children's behavior and cognitive abilities (e.g. representational complexity, ability to sustain selective attention, speed of processing)? Why, and how, is learning enhanced during certain periods in development? How is our knowledge organized, and how does this change with development? We discuss preliminary investigations of such questions and directions for future work.     

Developmental psychology and public policy: progress and prospects

This article outlines a framework for developmentally oriented policy research. Drawing from U. Bronfenbrenner's (1995) dynamic developmental systems theory, the authors suggest ways in which the key tenets of process, persons, context, and time can inform policy research in developmental psychology and can be used to support a causal interpretation of the results of those analyses. Conceptualizing public policies from a dynamic developmental systems perspective has a variety of implications for future research, and this article considers some of these implications.

Objectivity in ethics

In this paper I have tried to clarify the meaning of two very different sets of characteristics which philosophers have had in mind when they claimed that ethical terms were objective. I gave a very tentative answer to the question whether it is true to say that, in any of the distinguished senses, ethical statements are objective. Lastly, I indicated how the failure to make the distinction I draw was responsible for a number of confusions and unnecessary difficulties. More precisely, in (1) I defined the first set of the characteristics in question, which together I have called solidity; in (2) I give reasons why it is misleading to claim that ethical statements are solid and also misleading to claim they are not; in (3) I defined the second set of these characteristics, namely, proper contentiousness and proper complexity; in (4) I explained what I thought were the fundamental differences between these two sets of characteristics; in (5) I suggested that the solidity of an expression is normally a good reason for holding that the expression is properly contentious and properly complex; in (6) I claim that the failure to understand (4) and, therefore, also (5) leads to the following errors: (a) that, if an expression is solid, it must be properly contentious and properly complex; that, if an expression is non-solid, it must be either properly contentious and properly simple, or properly non-contentious. (5) That, if an expression is properly contentious and properly complex, it must be solid; if it is properly contentious and properly simple or if it is properly non-contentious, then it must be non-solid; and lastly in (7) I have mentioned some common reasons for holding that ethical expressions have one or the other of the above-mentioned characteristics.     

Asymmetries in ethics

Ethical notions such as good and bad, are often treated as though they were ‘symmetric’ in the sense of having the same moral ‘weight’, one in a positive the other in a negative sense. I argue that they are in fact ‘asymmetric’ and that the negative members of such pairs of notions are more fundamental and definite, logically speaking, and operationally more important than the positive members. Detailed arguments are given to show this for some non‐moral notions, such as life and death, health and illness; some semi‐moral notions such as pleasure and pain; and finally for the moral notions of happiness, benevolence, right, and good and their negative counterparts. One of the intentions of the article is to show that a systematic view of such asymmetries may have consequences for one's view of the proper or desirable structure of a general theory of ethics: norms stating prohibitions and norms stating permissions will be seen to be, in a sense defined in the text, more fundamental and important than norms stating ('positive') obligations.     

Ecology in ancient Greece

This article investigates the characteristic attitudes of the Greeks toward nature, which formed the perceptual framework for their ecological thinking. Two major attitudes are discerned. One regarded nature as the theatre of the gods, whose interplay produced observed phenomena, but whose localization gave them particular, restricted roles. The other attitude viewed nature as the theatre of reason, and made the beginnings of ecological thought possible. The contributions of several Greek forerunners in the field of ecology are characterized. The most consistent, balanced ecological writer in ancient Greece was Theophrastus, but his conception of an autonomous nature, interacting with man, was overshadowed in the history of ancient and medieval thought by the anthropocentric teleology of Aristotle.     

Medical ethics in Sweden

In this article a brief overview is given of the field of medical ethics in Sweden in recent years. The presentation concentrates on the occurrence of official ethical norms for physicians, current ethical committees, the educational situation, legislation in force, and some essential features of the ethical debate on a few central issues.     

Phronesis in clinical ethics

This essay argues that while we have examined clinical ethics quite extensively in the literature, too little attention has been paid to the complex question of how clinical ethics is learned. Competing approaches to ethics pedagogy have relied on outmoded understandings of the way moral learning takes place in ethics. It is argued that the better approach, framed in the work of Aristotle, is the idea of phronesis, which depends on a long-term mentorship in clinical medicine for either medical students or clinical ethics students. Such an approach is articulated and defended.     

Family relationships in Greek insulin-dependent diabetics

This exploratory pilot study was designed to investigate the relationship between Greek Insulin Dependent Diabetics and their family members. A secondary purpose was to explore the availability of sources for diabetes related education and to assess whether diabetics and their family members had seen a psychologist for counselling. Twenty patients with Insulin Dependent Diabetes Mellitus (IDDM) (Group A) and their parents (Group B), were randomly selected from a group of families attending the Athens Diabetic Centre of Social Security. Children and parents were given a specially prepared questionnaire, which addressed the impact of IDDM on their relationships and daily activities. There was also an interview with each of them separately. The results indicate that sources of education for diabetics are limited in Greece and that the majority of diabetics and their families have never seen a psychologist with a view to assessment and support. It is concluded that the diabetics in this study were generally content in their relationships with their parents although overprotectiveness by parents is a problem sometimes experienced by the children. After the initial shock of the diagnosis of diabetes, the majority of the families gradually returned to their premorbid state and relationship patterns.     

The development of computer ethics: Contributions from business ethics and medical ethics

In this essay, we demonstrate that the field of computer ethics shares many core similarities with two other areas of applied ethics, Academicians writing and teaching in the area of computer ethics, along with practitioners, must address ethical issues that are qualitatively similar in nature to those raised in medicine and business. In addition, as academic disciplines, these three fields also share some similar concerns. For example, all face the difficult challenge of maintaining a credible dialogue with diverse constituents such as academicians of various disciplines, professionals, policymakers, and the general public, Given these similarities, the fields of bioethics and business ethics can serve as useful models for the development of computer ethics. A version of this paper was presented at ETHICOMP98, the Fourth International Conference on Ethical Issues of Information Technology, March 25–27, 1998, Erasmus University, the Netherlands. Kenman Wong, Ph.D., is an Associate Professor of Business Ethics; Gerhard Steinke, Ph.D., is Professor of Management and Information Systems. Both authors are at Seattle Pacific University's School of Business and Economics.     

Medical ethics in Britain

This paper describes ‘the medical ethics scene’ in Britain. After giving a brief account of the structure of British medical ethics and of the roles of the different groups involved it mentions some of the important medico-moral events and issues of the fairly recent past, and describes in greater detail four important examples of professional, legal, governmental and media concerns with medical ethics, themselves illustrating the wide variety of interests wishing to influence the British medical profession's ethics. The examples offered are the development of research ethics committees, the Sidaway case concerning informed consent, the Warnock Committee's Report on in vitro fertilisation and associated issues, and the 1980 Reith Lectures on ‘Unmasking Medicine’. In the final section a fairly new methodological development in British medical ethics is described in which the medical profession is increasingly recognising the need to add to traditional medical ethics education, with its longstanding history of the inculation and enforcement of ethical norms, an element of philosophical or critical medical ethics, at the heart of which is justification of substantive medico-moral claims in the light of counterarguments.     

Medical ethics in Poland

The work related to medical ethics written by Polish authors are reviewed and some topics concerning teaching and various other activities in this field are presented. The attention is centered on the opinions and attitudes concerning the essence of medical profession and the personal model of the physician, doctor-patient relationship (including duties of the doctor), medical research on humans, abortion and other problems. The role of medico-ethical tradition in Poland is described. Main trends in polish ethical thought in relation to medicine are taken into consideration. General aspects of medical ethics in present-day Poland are tentatively characterized.
