[Nursing research in Finland from 1950s to the present].

In Finland nursing education and research in universities was established in 1979. Research in nursing, however, was done in some amount even before in other disciplines and in the Institute of Nursing Research. In this article, nursing research during 1958-1995 is described, based on the articles in the Finnish Yearbook of Nursing (1958-1988), in the Journal of Nursing Science (Hoitotiede, 1989-1995) and academic licentiate and doctoral dissertations. The analysis indicates strong growth of nursing research in Finland since 1950s. The content of research is multidimensional. The nature of research is quantitative and descriptive; many of the doctoral dissertations in 1990s are qualitative. The research interest has been mainly the patient. Articles in research methods and concept analysis are rare.

Psychological testing, IQ, and evolutionary fitness.

Individual group, and ethnic differences in behavior have been an object of long, continuing, and contentious interest, both in the sciences and in popular culture. For well over 2,000 years, psychological traits, particularly those described as 'intelligence', have generally been considered the major factors in fitness in humans. After reviewing contemporary scientific thinking on intelligence, the psychometric methods used for the construction of psychological tests are presented and examined in the context of natural selection and metric characters. There are essential differences between the disciplines of genetics and of psychology such that the concepts of the two are more divergent than might superficially appear to be the case. The analysis leads to the conclusion that standard psychometric methodology cannot yield tests appropriate for measurement of evolutionary fitness characters.

Nanotechnology on duty in medical applications.

At the beginning of 21(st) century, fifty years after discovery of deoxyribonucleic acid (DNA) double helix structure, scientific world is faced with a great progress in many disciplines of biological research, especially in the field of molecular biology and operating on nucleid acid molecules. Many molecular biology techniques have been implemented successfully in biology, biotechnology, medical science, diagnostics, and many more. The introduction of polymerase chain reaction (PCR) resulted in improving old and designing new laboratory devices for PCR amplification and analysis of amplified DNA fragments. In parallel to these efforts, the nature of DNA molecules and their construction have attracted many researchers. In addition, some studies concerning mimicking living systems, as well as developing and constructing artificial nanodevices, such as biomolecular sensors and artificial cells, have been conducted. This review is focused on the potential of nanotechnology in health care and medicine, including the development of nanoparticles for diagnostic and screening purposes, the manufacture of unique drug delivery systems, antisense and gene therapy applications and the enablement of tissue engineering, including the future of nanorobot construction.

[Scientific aspects of raw materials in medicine].

Metallic, ceramic, and polymeric materials are applied in all disciplines of surgical and dental medicine. The biocompatibility is determined by the chemical composition, the mechanical and electronic structures of the material's surface, the properties of the interface to the specific body electrolyte as well as by reactions, which occur between the solid and the liquid phase. The development of biomaterials, considering the sensitive biological environment, requires knowledge from all fields of the natural sciences and knowledge of manufacturing methods derived from the key technologies.

Between economics and ecology: some historical and philosophical considerations for modelers of natural capital.

Natural capital models attempt to remediate the relationship between economics and ecology either by conjoining models and theories from each discipline or by finding a type of phenomena that can be meaningfully measured by both fields. The development of a widely accepted model that integrates economics and ecology has eluded researchers since the early 1970s. This paper offers an historical and philosophical perspective on some of the conceptual problems or obstacles that hinder the development of natural capital models. In particular, the disciplinary assumptions of economic science and ecological science are examined and it is argued that these assumptions are antithetical. Hence, the development of an effective and accepted natural capital model will require that economics and ecology reconsider their self-conceptions as sciences. For the purposes of theoretical research and practical policy, the paper cautions against confusing the issue of whether or not economic models accord with ecological models with the issue of whether or not economic activities accord with ecological realities.

Rasayana therapy in classical literature of Ayurveda: a review.

Ayurveda is a science of life, therefore it is the science, by the knowledge of which life may be prolonged. It is human nature to aspire for longevity and this desire is found practically among all the peoples of the world. Accordingly if longevity is desired, there must be a system of rejuvenation for one who keeps on remaining young. Rasayana therapy has been described for this person in Ayurveda as a systematic and scientific medical discipline and great results were claimed by this therapy. Hence the Rasayana therapy has been reviewed in the various headings giving its uses, definition, types and formulations etc.

Psychopharmacology: finding one's way.

The paper recalls the experiences of the author over the past forty-eight years in a field which later became known as psychopharmacology. The author began in physical chemistry and traditional pharmacology. His interest in the nervous system stemmed from X-ray diffraction studies on the structure of living myelin, and led, by way of studies on the distribution of cholinesterases and the effects of atropine, to the study of the effects of drugs on the electrical activity of the brain in the conscious animal. At the clinical level it included studies of the effects of drugs on catatonic schizophrenic stupor. These studies took place before the discovery of chlorpromazine. They led to the creation, in 1951, of the Department of Experimental Psychiatry in Birmingham, England, the first department of its kind in the world. The department included neurochemical, electrophysiological, and animal behavior laboratories and a strong clinical facility (the Uffculme Clinic). The first blind trial of chlorpromazine was carried out in that department in 1953 and 1954. The existence of families of neuroregulatory compounds, having uneven distribution in the brain, and exerting regional chemical field effects in relation to function was postulated on the basis of experimental and clinical findings. The work of colleagues and participants in the various studies is gratefully acknowledged in the text. In 1954 the author served as convening executive secretary of the first International Symposium on Neurochemistry at Oxford, England, the first meeting of its kind. He came to the United States in 1957 and founded, and served as first director of, the new Clinical Neuropharmacology Research Center, now the Center for Neuroscience at St. Elizabeth's Hospital, Washington, DC. He directed this program from 1957 to 1963. Subsequent activities at Johns Hopkins, the World Health Organization, and the International Brain Research Organization (IBRO) are recalled. In 1961 he was elected first president of the American College of Neuropsychopharmacology. In looking back, he notes the sparse and personal nature of the field in the late 1940s and early 1950s, its explosive growth in the wake of the major clinical discoveries, and above all, the emergence of a new science through the interaction of neurochemistry, electrophysiology, studies of animal behavior, and the refinement of the clinical trial. He regards the emergence of concepts of regional chemistry of the brain as particularly significant, and feels that psychopharmacology is ideally positioned to act as an intermediary between classical pharmacology and quantrum biology. The transdisciplinary nature of psychopharmacology provides a template for a comprehensive psychiatry of the future--a discipline which is now positioned to lead.(ABSTRACT TRUNCATED AT 400 WORDS)

Education challenges in the North Sea area.

This paper introduces the North Sea as a fast evolving coastal ecosystem. The variability of natural conditions relates to the global climatic change and to human disturbances, which originate regionally. Education is an integral part of the strategy to improve environmental awareness. Considering contemporary challenges for educating the wider public about the main issues of environmental concern, attention is paid to various plans, which are being developed in North-Western Europe from primary schools to universities. "Learning for life" relies on an opening of the vocation of traditional universities and on the creation of a European university. Sharing resources in a competitive environment is one response given by British universities in the framework of a Discipline Network in Coastal Sciences and Management in 1996-2000. Networking is truly the key to a fast evolving teaching and learning context, notably in relation to ever developing information and communication technologies. The dissemination of scientific information is primordial in this context; a case study relating to the European project "Marine biodiversity in Europe" (BIOMARE) demonstrates the need for an elaborated strategy leading to socio-economic considerations. Empowering communities and governance are the main possible outcomes of such an enlarged approach to education, involving teachers, students, researchers, professionals, and volunteers. Proposals are made for amplifying the involvement of non-scientists into scientific research and its applications to management. Finally, a case is made for facilitating the mobility of all concerned, with a view to annihilate language and cultural barriers.

Extraction of biological interaction networks from scientific literature.

Biology can be regarded as a science of networks: interactions between various biological entities (eg genes, proteins, metabolites) on different levels (eg gene regulation, cell signalling) can be represented as graphs and, thus, analysis of such networks might shed new light on the function of biological systems. Such biological networks can be obtained from different sources. The extraction of networks from text is an important technique that requires the integration of several different computational disciplines. This paper summarises the most important steps in network extraction and reviews common approaches and solutions for the extraction of biological networks from scientific literature.

[Rehabilitation as a subject of health services research].

Since the mid-1990s, the lack of proper development in health services research in the healthcare system of the Federal Republic of Germany has been repeatedly criticised by healthcare policy-makers and experts alike, whilst also being the subject of a number of reform initiatives. Rehabilitation sciences, which were established in Germany as an autonomous scientific discipline in the early 1990s, could benefit in terms of conception, methodology and organisation from these activities and the new interest bestowed on healthcare sector research. At the same time, the converse also holds true since from the very beginning health services research has played a particular role in the development of rehabilitation sciences-unlike the role it has played in the overall healthcare system. The complex nature of the areas of research covered by rehabilitation, together with the theoretical plurality and methodological diversity associated with it, may be ascribed to the fact that (up to the present) this sector has lacked a broader framework connecting together health research concerns and issues. This article presents a comprehensive overview of current concerns and issues as evidenced in publications of the past 15 years that make an explicit contribution to health services research. It highlights the rehabilitation system research undertaken in the past decade as a central plank of health services research. Furthermore, it also investigates the backdrop to health services research in rehabilitation in terms of its development, its research concerns, its methodology, its organisation and its infrastructural embeddedness.

A survey on the 'premedical syndrome'.

The "premedical syndrome" has been widely discussed but only anecdotally described. To learn whether the syndrome exists in the South Carolina schools and which traits compose it, the authors surveyed faculty members and students of 13 undergraduate colleges in the state. Premedical students were perceived as differing from nonpremedical students in being excessively competitive, academically, overspecialized , overachieving , more highly motivated, more highly self-disciplined, goal-oriented, and proud of their career choice. The perception by students and faculty members of the premedical syndrome may have important effects on the undergraduate curriculum and students' choices of major areas of study. Only 3 percent of the premedical students who responded to the survey were majoring in the liberal arts, and only 9 percent of the nonpremedical students were majoring in the natural sciences. These data suggest that the natural science departments in U.S. colleges may have become training grounds for premedical students to the exclusion of others. Modification of medical school admissions policies may be able to reverse some features of the premedical syndrome and some of its effects.

[The role of a specialised risk analysis group in the Veterinary Services of a developing country].

Since the World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures was established, risk analysis in trade, and ultimately in Veterinary and Animal Health Services, has become strategically important. Irrespective of their concept (discipline, approach, method, process), all types of risk analysis in trade involve four periods or phases:--risk identification-- risk assessment--risk management--risk information or communication. All veterinarians involved in a risk analysis unit must have in-depth knowledge of statistics and the epidemiology of transmissible diseases, as well as a basic knowledge of veterinary science, economics, mathematics, data processing and social communication, to enable them to work with professionals in these disciplines. Many developing countries do not have enough well-qualified professionnals in these areas to support a risk analysis unit. This will need to be rectified by seeking strategic alliances with other public or private sectors that will provide the required support to run the unit properly. Due to the special nature of its risk analysis functions, its role in supporting decision-making, and the criteria of independence and transparency that are so crucial to its operations, the hierarchical position of the risk analysis unit should be close to the top management of the Veterinary Service. Due to the shortage of personnel in developing countries with the required training and scientific and technical qualifications, countries with organisations responsible for both animal and plant health protection would be advised to set up integrated plant and animal risk analysis units. In addition, these units could take charge of all activities relating to WTO agreements and regional agreements on animal and plant health management.

Concept analysis: examining the state of the science.

As methods for analyzing concepts have proliferated in nursing, a critical methodological issue has arisen. Analytic techniques for examining conceptual meaning have incorporated varied strategies for advancing the concept under the rubric of concept analysis, concept development, and theory building. The authors argue that this evolution has created methodological confusion. Following a discussion of a conceptualization of concepts and concept-theory-truth linkages, methods of concept analysis are critiqued in terms of the purpose and the nature of the findings produced by analyses using both traditional and emergent methods. The authors argue that concept analysis is a process of strategic examination of the scientific literature that results in an integrated perspective of the state of the science, or what is known about the concept. In contrast, concept advancement refers to techniques that emphasize the synthesis of new or deeper knowledge that is relevant to the discipline. The authors conclude that disentangling concept analysis from techniques for concept advancement is critical to enhancing the utility of concept-based research in nursing.

Evolutionary psychology: toward a unifying theory and a hybrid science.

Although evolutionary psychology is typically associated with "selfish gene theory," numerous other approaches to the study of mind and behavior provide a wealth of concepts for theorizing about psychology, culture, and development. These include general evolutionary approaches and theories focused on sociality, dual inheritance, multilevel selection, and developmental systems. Most evolutionary accounts use the same methods as Darwin-the "fit among facts"-to use natural selection as an explanation for behavior. Scientific standards for constraining and evaluating such accounts, research into the mutual influence of science and society on the understanding of evolution, and computational technologies for modeling species-typical processes are important considerations. Coevolutionary theories and developmental systems theories may eventually give rise to unification in a broad and general sense. Such a unification would be interdisciplinary and problem centered rather than discipline centered.

Molecular profiling of single cells and tissue specimens with quantum dots.

Quantum dots are tiny light-emitting particles on the nanometer scale. They are emerging as a new class of biological label with properties and applications that are not available with traditional organic dyes and fluorescent proteins. Recent advances, as reported in Science and Nature Biotechnology, have led to quantum dot bioconjugates that are highly luminescent and stable. These bioconjugates raise new possibilities for studying genes, proteins and drug targets in single cells, tissue specimens and even in living animals.
