Light effects on the activity of several genes have recently been exploited in studies of plant gene expression. We discuss here some examples involving nuclear genes of higher plants, with emphasis on responses mediated by the phytochrome system. Recent work has revealed considerable diversity in the responses of different genes, indicating that several different regulatory programs are probably involved. A start has been made in studies of nuclear events associated with the changes in expression. Transcriptional regulation almost certainly occurs, although (...) many details remain to be studied and effects on mRNA processing and turnover have not been ruled out. Recent in vitro mutagenesis and gene transfer experiments with the gene for the small subunit of RuBP carboxylase indicate that sequences involved in regulating the level of expression in the light are located 5′ to the gene within about 1 kb of the start of transcription.

The paper examines some implications of Parsonian theory of social change for the philosophy of history. A distinction is made between two concepts of social change, the first concerning transformations within a stable structure, the second concerning transformations of the structure (metamorphose). The principal meta-histori cal postulates underlying the functional analysis of social change are then formulated. They imply a twofold conception of the meaning of history : objective meaning as a functional property of a teleological system, subjective meaning as (...) an intentional correlate of the individual actors. This irreducible duality of system theory and action theory characterizes the whole Parsonian approach to the theory and history of societies. (shrink)

This is an engaging book on a subject which most people in our culture assume went out of fashion long ago. The book had its genesis in one of a series of symposia convened by the Church Society for College Work of Cambridge to explore certain themes and ideas which have great import for our time. The various authors of the essays eschew the habit of viewing Transcendence as the traditional content of metaphysical arguments or revelatory statements about the nature (...) of God outside or independent of the world and seek for signs of the possibility of achieving a renewed sense of Transcendence in the domains of inner experience, history, culture, language, science, technology, and the arts. Huston Smith suggests two options of human fulfillment: psychological and ontological, both providing a kind of transcendence of self and society. He refuses to accept one and reject the other but instead to convince us that both are legitimate. M. Murphy claims that the experience of psychological and social transcendence can be fostered by educational projects such as encounter groups, gestalt therapy workshops and sensitivity training programs. In his "Manifesto for a Dionysian Theology," Sam Keen analyzes the Apollonian way of reasoning and planning which has come to dominate in Western culture and makes a plea for a reassertion of the Dionysian principle in religion which might be expressive of life as dance, centrality of feelings and sensations, a pantheistic conception of God and a theology of play. Harvey Cox asserts that our society has lost its capacity for utopian fantasy resulting in the inability to conceive of any world which is not a mere modification or extension of our own world. He suggests that we consciously become "fools for Christ" again and give full rein to our powers of creative fantasizing even at the risk of contracting "religious madness." Donald Schon urges post-modern man to give up hope for achieving a stable political order and to develop an "ethic for change" appropriate to the demands of our society where change is all-pervasive. Essays by R. Bellah and H. Richardson explore myths of transcendence as ordering structures in society and plead for increased attention to correspondences among the disciplines of theology, sociology, and psychology. E. Fackenheim and W. Kaufman seek to clarify the notion of transcendence in Judaism and Christianity respectively and to "clear the way for a positive revelation." In keeping with the shared notion that transcendent reality is present and active within the human process, two eminent process philosophers, Wieman and Hartshorne discuss the "implications for a concept of transcendence that follows from affirming the creative freedom of man." The essays singly and together reject the notion that the existence and nature of transcendent reality can be arrived at by pursuing a single line of argumentation to its bitter end and instead they work together from various points of view to reinforce our sense of man's renewed thirst for the Divine and the subsequent rediscovery of God's uninterrupted presence within the world of "Immanent Possibility."--J.

In Wrong Medicine, Lawrence J. Schneiderman, M.D., and Nancy S. Jecker, Ph.D., address issues that have occupied the media and the courts since the time of Karen Ann Quinlan. The authors examine the ethics of cases in which medical treatment is offered--or mandated--even if a patient lacks the capacity to appreciate its benefit or if the treatment will still leave a patient totally dependent on intensive medical care. In exploring these timely issues Schneiderman and Jecker reexamine the doctor-patient relationship and (...) call for a restoration of common sense and reality to what we expect from medicine. They discuss economic, historical, and demographic factors that affect medical care and offer clear definitions of what constitutes futile medical treatment. And they address such topics as the limits on unwanted treatment, the shift from the "Age of Physician Paternalism" to the "Age of Patient Autonomy," health care rationing, and the adoption of new ethical standards.

Health care services increasingly face patient populations with high levels of ethnic and cultural diversity. Cultures are associated with distinctive ways of life; concepts of personhood; value systems; and visions of the good that affect illness experience, help seeking, and clinical decision-making. Cultural differences may impede access to health care, accurate diagnosis, and effective treatment. The clinical encounter, therefore, must recognize relevant cultural differences, negotiate common ground in terms of problem definition and potential solutions, accommodate differences that are associated with (...) good clinical outcomes, and manage irresolvable differences. Clinical attention to and respect for cultural difference (a) can provide experiences of recognition that increase trust in and commitment to the institutions of the larger society, (b) can help sustain a cultural community through recognition of its distinct language, knowledge, values, and healing practices, and (c) to the extent that it is institutionalized, can contribute to building a pluralistic civil society.

Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)

Background Informed consent is an integral component of good medical practice. Many researchers have investigated measures to improve the quality of informed consent, but it is not clear which techniques work best and why. To address this problem, we propose developing a core outcome set to evaluate interventions designed to improve the consent process for surgery in adult patients with capacity. Part of this process involves reviewing existing research that has reported what is important to patients and doctors in the (...) informed consent process. Methods This qualitative synthesis comprises four phases: identification of published papers and determining their relevance; appraisal of the quality of the papers; identification and summary of the key findings from each paper while determining the definitiveness of each finding against the primary data; comparison of key themes between papers such that findings are linked across studies. Results Searches of bibliographic databases returned 11,073 titles. Of these, 16 studies met the inclusion criteria. Studies were published between 1996 and 2016 and included a total of 367 patients and 74 health care providers. Thirteen studies collected data using in-depth interviews and constant comparison was the most common means of qualitative analysis. A total of 94 findings were extracted from the primary papers and divided into 17 categories and ultimately 6 synthesised findings related to: patient characteristics, knowledge, communication, the model patient, trust and decision making. Conclusions This qualitative meta-aggregation is the first to examine the issue of informed consent for surgery. It has revealed several outcomes deemed important to capture by patients and clinicians when evaluating the quality of a consent process. Some of these outcomes have not been examined previously in research comparing methods for informed consent. This review is an important step in the development of a COS to evaluate interventions designed to improve the consent process for surgery. Registration The study protocol was registered on the international prospective register for systematic reviews. (shrink)

Examining those risk and benefit perceptions utilised in the formation of attitudes and opinions about emerging technologies such as nanotechnology can be useful for both industry and policy makers involved in their development, implementation and regulation. A broad range of different socio-psychological and affective factors may influence consumer responses to different applications of nanotechnology, including ethical concerns. A useful approach to identifying relevant consumer concerns and innovation priorities is to develop predictive constructs which can be used to differentiate applications of (...) nanotechnology in a way which is meaningful to consumers. This requires elicitation of attitudinal constructs from consumers, rather than measuring attitudes assumed to be important by the researcher. Psychological factors influencing societal responses to 15 applications of nanotechnology drawn from different application areas were identified using repertory grid method in conjunction with generalised Procrustes analysis. The results suggested that people differentiate nanotechnology applications based on the extent to which they perceive them to be beneficial, useful, necessary and important. The benefits may be offset by perceived risks focusing on fear and ethical concerns. Compared to an earlier expert study on societal acceptance of nanotechnology, consumers emphasised ethical issues compared to experts but had less concern regarding potential physical contact with the product and time to market introduction. Consumers envisaged fewer issues with several applications compared to experts, in particular food applications. (shrink)

An alternative notion of an existential quantifier on four-valued Łukasiewicz algebras is introduced. The class of four-valued Łukasiewicz algebras endowed with this existential quantifier determines a variety which is denoted by \. It is shown that the alternative existential quantifier is interdefinable with the standard existential quantifier on a four-valued Łukasiewicz algebra. Some connections between the new existential quantifier and the existential quantifiers defined on bounded distributive lattices and Boolean algebras are given. Finally, a completeness theorem for the monadic four-valued (...) Łukasiewicz predicate calculus corresponding to the dual of the alternative existential quantifier is proven. (shrink)

The literature on public perceptions of, and attitudes towards, nanotechnology used in the agrifood sector is reviewed. Research into consumer perceptions and attitudes has focused on general applications of nanotechnology, rather than within the agrifood sector. Perceptions of risk and benefit associated with different applications of nanotechnology, including agrifood applications, shape consumer attitudes, and acceptance, together with ethical concerns related to environmental impact or animal welfare. Attitudes are currently moderately positive across all areas of application. The occurrence of a negative (...) or positive incident in the agri-food sector may crystallise consumer views regarding acceptance or rejection of nanotechnology products. •Acceptance of agrifood nanotechnology based on perceptions of risk, benefit and ethics.•Attitudes towards nanotechnology in general are currently moderately positive.•Occurrence of a major nanotechnology-related "event" may crystallise consumer attitude.
