Environmental needs and social justice

Despite the growth in awareness and practical action to maintain biodiversity, environmental degradation and ecosystem destruction has continued at a high rate over the last 20 years. The roots of this lie in the predominant international economic order, underpinned by lifestyle demands for increased material consumption. Net flow of wealth from South (less developed) to North (more developed) nations has exacerbated a spiral of increased poverty and environmental degradation in the former. Global environmental conservation depends upon a radical change of direction with the principle of equity as the starting point. Notwithstanding the importance of continuing to add to local and small-scale conservation achievements, the prospect of radical change happening seems small, despite it being in the long-term self-interest of the North. The concept of equity is, apparently, unacceptable to Northern electorates.     

The acquisition of conscience and Developmental Systems Theory

Summary Proponents of Developmental Systems Theory (DST) argue that it offers an alternative to current research programs in biology that are built on the historic disjunction between evolutionary and developmental biology. In this paper I illustrate how DST can be used to account for the acquisition of an important component of moral agency, conscience. Susan Oyama, a major proponent of DST, has set moral issues outside the compass of DST. Thus, I examine her reasons for restricting DST to non-moral matters, and argue that they are not decisive. On the positive side, I argue that DST not only is compatible with attempts to describe and explain moral agency but also aids us in understanding it. In particular, I show how DST can provide a fruitful perspective for viewing some significant current findings and theories in moral developmental psychology about the acquisition of conscience. The familiar dichotomies resisted by DST, those between genes and environment, inherited and acquired, innate and learned, and biological and cultural, have also plagued human developmental psychology, including moral development. By bringing a DST perspective to the study of moral development, I illustrate how a DST perspective might offer a promising way to reconceive that phenomenon, and provide some insights into how further work in understanding the development of moral agency might proceed. Thus, I hope to contribute to the current efforts of proponents of DST to integrate developmental and evolutionary considerations.     

Animal learning and intelligence

The ability to learn is common to most animal species: the need to exploit past experience being obviously extremely important for survival, many animals have evolved ways of coping with it. Although the complexity of learning needed for optimal survival may be different in different species, the basic mechanisms appear to be fairly constant even in phylogenetically distant ones. This homogeneity across species in learning mechanisms is in some ways surprising in view of the large phylogenetic differences and of the considerable variability not only in the general plan of their bodily structures, but also, more specifically, in their neural organization and in their behavioral adaptations. One possible explanation is that animals have acquired learning very precociously, and that the original and basic mechanisms have proved so efficient and faultproof as to be preserved from then on without any significant modification. Most researchers of the subject seem to accept the equation «intelligence=learning capability», operationally very useful because it leads to a variety of formal tests. Some researchers, stressing that behavior is subject to the same evolutionary principles as any other character of the organism and acknowledging some problems in the accepted laws of learning, have tried to find a satisfactory answer to the question of animal intelligence by attempting a synthesis between the concepts of animal learning psychology and those of ethology. To some extent, dissatisfaction with established learning theories originated within the theories themselves: the study of phenomena such as autoshaping, selective attention, preferential learning of some responses amongst the many possible, conditioned learning of taste aversions, etc. Further difficulties for conditioning theories arose from the discovery of ethological phenomena. Other researchers have attempted to check the hypothesis that animals possess cognition. A number of complex experimental situtations have been devised to this purpose, but the results still are far from conclusive.     

Psychological perspectives of ecosystem health

Behavior-based and person-based perspectives are integrated to summarize approaches for dealing with the human element of ecosystem health. Behavior is selected by its consequences, and therefore interventions are needed to decrease the natural reinforcing consequences (e.g., convenience, efficiency) of environment-destructive behaviors and to increase the reinforcing consequences of environment-protective behaviors. An ABC Model (for Activator-Behavior-Consequence) can be applied effectively to design intervention programs for benefiting the human behavior aspects of ecosystem health. However, intervention agents are needed to implement positive behavior-change techniques, and this requires people to actively care enough to emit other-directed (or altruistic) behaviors for the health of the ecosystem. Person factors which influence one's propensity to actively care include: self-esteem, belongingness, and empowerment, influenced by perceptions of self-efficacy (I can do it), personal control (I am in control), and optimism (I expect the best). Strategies are reviewed for increasing these person states or expectancies. The health of our ecosystem depends upon people changing their behaviors and attitudes regarding the environment. Behavior-based psychology offers the technology for changing behaviors and attitudes in desirable directions; person-based psychology offers the states or expectancies needed in people to increase their willingness to actively care for the environment. By applying the theory and principles from these subdisciplines of applied psychology, the critical human element of our ecosystem can be accounted for and managed effectively.     

Pathways in the emergence of developmental neuroethology: Antecedents to current views of neurobehavioral ontogeny

The historical forces that have contributed to our current views of neurobehavioral development (and thus to the fields of developmental psychobiology and neuroethology) are many and varied. Although similar statements might be made about almost any field of science, it is in particular true of this field, which represents a kind of mongrel discipline derived from at least three major sources (psychology, embryology, and neuroscience) and several more minor ones (including developmental psychology and psychiatry, psychoanalysis, education, zoology, ethology, and sociology). Although I attempt to demonstrate here how each of these sources may have influenced the emergence of a unified field of developmental psychobiology or developmental neuroethology, because the present article represents the first attempt of which I am aware to trace the history of these fields I am certain that there is considerable room for improvement, correction, and revision of the views expressed here. Accordingly, I consider this inaugural effort a kind of reconnaissance intended to trace a necessarily imperfect historic path for others to follow and improve upon. In the final analysis, I will be satisfied if this article only serves to underscore two related points: first is the value derived from historical studies of contemporary issues in development, and the second concerns the extent to which our current ideas and concepts about neurobehavioral development, ideas often considered new and contemporary, were already well known to those who came before us. The first point underscores the arguments expressed in the Introduction that the present must always be reconciled with the past, for the past is never entirely past. The second point returns full circle to an important thought expressed in the opening quotation to this article, namely, that even though our historic predecessors lacked much of the empirical facts available to us they were nonetheless able to attain a surprisingly deep understanding of neurobehavioral ontogeny. © 1992 John Wiley & Sons, Inc.     

REEXAMINATION OF THE ETHICS OF PLACEBO USE IN CLINICAL PRACTICE

A placebo is a substance or intervention believed to be inactive, but is administered by the healthcare professional as if it was an active medication. Unlike standard treatments, clinical use of placebo usually involves deception and is therefore ethically problematic. Our attitudes toward the clinical use of placebo, which inevitably includes deception or withholding information, have a tremendous effect on our practice regarding truth‐telling and informed consent. A casual attitude towards it weakens the current practice based on shared decision‐making and mutual trust between patients and healthcare professionals. Issues concerning the clinical use of placebo are thus intimately related to patient‐provider relationships, the public's trust in medicine, and medical education. A review of recent survey studies suggests that the clinical use of placebo appears to be fairly well accepted among healthcare professionals and is common in clinical settings in various countries. However, we think that an ethical discussion is urgently needed because of its controversial nature. If judged to be ethically wrong, the practice should end. In the present paper, we discuss the ethicality of the clinical use of placebo with deception and argue against it, concluding that it is unethical and should be banned. We will show that most arguments in favor of the clinical use of placebo can be refuted and are therefore incorrect or weak. These arguments will be presented and examined individually. Finally, we will briefly consider issues relevant to the clinical use of placebo without deception.     

L.S. Vygotsky and the Theater

The article presents the analysis of L.S. Vygotsky's works dedicated to the theater arts and is organized according Vygotsky's different life and work stages. Meanwhile special attention is paid to the Gomel period during which a large number of reviews were written by Vygotsky and published in “Nash ponedel'nik” and “Polesskaia pravda” newspapers. Biographical facts are widely used in this analysis and help to clarify Vygotsky's interest in art. It is shown that even at the beginning of his oeuvre, he was interested not only in a range of problems in art, but also psychological problems related to art perception and creativeness. Vygotsky's usage of structural concept ideas about the peculiar properties of literary text composition are also explored. Vygotsky analyzes the socio-psychological mechanisms of theatrical art effect. Furthermore, those areas which are widely used by Vygotsky in determining the characteristics of cast reincarnation are examined. Special emphasis is placed on the different elements of the actor techniques (speech, movement, emotional expression, acting personality and etc.). Materials are widely used in this study and help identify the socio-cultural context that defined Vygotsky's values at different stages of his work, related to his drama criticism and his formation as a professional psychologist.     

Three New Polyacetylene Glycosides from the Roots of Heracleum dissectum and Their Triglyceride Accumulating Activities in 3T3‐L1 Cells

Continually phytochemical study of the roots of Heracleum dissectum had led to the isolation of three previously undescribed polyacetylene glycosides ( 1 – 3 ), together with seven known compounds, including one polyacetylene ( 8 ) and six coumarins ( 4 – 7 and 9 – 10 ) using diverse chromatographic methods. The structures of these three new compounds were characterized and identified as deca‐4,6‐diyn‐1‐yl β‐d ‐glucopyranosyl‐(1→6)‐β‐d ‐glucopyranosyl‐(1→2)‐β‐d ‐glucopyranoside ( 1 ), (8Z)‐dec‐8‐ene‐4,6‐diyn‐1‐yl β‐d ‐glucopyranosyl‐(1→6)‐β‐d ‐glucopyranosyl‐(1→2)‐β‐d ‐glucopyranoside ( 2 ), and (8E)‐dec‐8‐ene‐4,6‐diyn‐1‐yl β‐d ‐glucopyranosyl‐(1→6)‐β‐d ‐glucopyranosyl‐(1→2)‐β‐d ‐glucopyranoside ( 3 ) based on their physicochemical properties and extensive analyses of various spectroscopic data. Their triglycerides accumulating activities were assayed and the results showed that the three new polyacetylene glycosides ( 1 – 3 ) exhibited triglyceride accumulating activities in 3T3‐L1 adipocytes.     

A modest proposal for restoration ecology

Restoration ecology struggles to mitigate human‐caused ecological damage. Non‐native species are a particular challenge. This article describes two restoration attempts following introduced species in California and then makes a radical culling proposal. Environmental regulations, legal protections, and restoration projects are necessary to preserve ecosystem services, but such policies are often unpopular. Restorers often struggle when public opinion opposes evidence‐based practice, and this occurs particularly when the interventions involve killing mammals. Therefore, restoration efforts may benefit from more attention to how individuals perceive the acceptability of environmental policies and how to communicate policy options effectively for individuals to make informed decisions. Restoration ecology can follow the recent shift of medicine away from imperatives and toward informed patient choice. Restoration projects may benefit from recent advances in psychology and communication that help individuals make policy decisions that align with their personal values.
