Scientific Progress (scientific + progress)
Selected AbstractsWhat Is Scientific Progress?NOUS, Issue 1 2007Alexander Bird First page of article [source] Milestones in ecological thought , A canon for plant ecologyJOURNAL OF VEGETATION SCIENCE, Issue 2 2005Paul A. Keddy Abstract. Scientific progress in plant ecology is at risk of being obscured by increasing ignorance of major works in the field. The driving force seems to be the twin seductions of novelty and crowd psychology. I illustrate this tendency with three examples from plant community ecology that span the past thirty years of ecological research. I offer, as one solution, the concept of a canon: a short list of essential books that we assume all students and co-workers have read, a short list that summarizes the wisdom of the discipline. A canon can be likened to DNA, be it in music, art, or science, as it carries forward through time the key ideas that have worked in the past. Without a canon, there is no memory of past achievement, no context for appreciating current work, and no way of judging the quality of newer productions. I suggest 20 essential books (the short canon), and 22 complementary readings, for a total of 42 books needed in any young professional's library on plant ecology.

Scientific progress has occurred in anthropology over the past century despite the distortions of colonialism, the Cold War, and other historical circumstances. Controversies about good and bad scientific work and about the humanistic character of anthropology have been an ongoing aspect of our discipline.

Scientific progress accelerates the rate of technological progress, but diminishing returns to technological research decelerates it. This process repeats itself with endogenous clustering of innovations. We show that higher trend (long-run) growth is associated with more frequent waves of economic activity. Moreover, we identify a trade-off between actual and trend growth rates when technological research activities are subsidized. [source] Structure and development of decision-support systems and their use by the State Plant Protection Services in Germany,EPPO BULLETIN, Issue 1 2000B. Kleinhenz To ensure continuing work on decision-support systems (DSSs) and the elaboration of new systems according to the needs of the Plant Protection Services of the federal states of Germany, these services have installed ZEPP (Central Institution for Decision Support Systems and Programmes in Crop Protection). At the national level, ZEPP guarantees a permanent supply of meteorological data, organizes and co-ordinates trials, incorporates scientific progress into the existing DSSs and, in close co-operation with universities and federal research stations, develops new systems for important pests. The PASO desktop system includes a data bank that administers all relevant meteorological files and field data. It allows for automated simulation runs and forecasts, serving as input for timely warnings by different media. Depending on the individual decision-support modules, results are presented as tables and/or graphs. [source] Domestic Politics and International RelationsINTERNATIONAL STUDIES QUARTERLY, Issue 1 2002Bruce Bueno De Mesquita In reviewing the history of portions of international studies I reflect on how we might best advance knowledge. I dwell on two issues: questions of method and the urgency of refocusing our efforts on leaders and domestic affairs as the centerpiece for understanding the world of international relations. I argue that scientific progress is best made by combining three methodological approaches in our research: formal, mathematical logic to ensure internal consistency in arguments about complex and contingent relations among variables; case studies and archival research to evaluate verisimilitude between theory and action; and statistical analysis to establish the generality of the hypothesized relations among variables. Often such methodologically diverse and progressive research will best be accomplished by encouraging collaboration rather than by perpetuating the current norm of penalizing co-authorship especially among junior scholars. I offer concrete examples of advances in knowledge achieved through the employment of mathematical reasoning and statistical analysis as many have cast doubts about the substantive contributions of these particular approaches. My perspective is, of course, personal and may not be shared by many others. I set out my thoughts, therefore, with the hope that they will stimulate constructive debate and dialogue and that they will serve to integrate diverse approaches to international affairs. [source] The Study of Democratic Peace and Progress in International Relations,INTERNATIONAL STUDIES REVIEW, Issue 1 2004Fred Chernoff This essay argues that the field of international relations has exhibited "progress" of the sort found in the natural sciences. Several well-known accounts of "science" and "progress" are adumbrated; four offer positive accounts of progress (those of Peirce, Duhem, Popper, and Lakatos) and one evidences a negative assessment (Kuhn). Recent studies of the democratic peace,both supporting and opposing,are analyzed to show that they satisfy the terms of each of the definitions of scientific progress. [source] Toward a consilient science of psychologyJOURNAL OF CLINICAL PSYCHOLOGY, Issue 1 2005Kevin L. Rand From its inception, psychology has been characterized by conceptual fragmentation and slow scientific progress (Henriques, 2004; Meehl, 1978). In contrast, the natural sciences have achieved in recent decades a remarkable degree of consilience,the linking of fact, theory, and method across disciplines (and subdisciplines) and across nested levels of informational complexity (Wilson, 1998). Although such consilience serves as a potent catalyst of scientific discovery, there exists several barriers to the emergence of a consilient science of psychology (e.g., the persistent influence of dualism, longstanding internecine discord, resistance to perceived reductionism, etc.). We discuss the manner in which the development of metatheoretical frameworks (including Henriques' Tree of Knowledge model) may play an important role in addressing such barriers. Likewise, we describe the hybrid interdisciplinary domain of cognitive neuroscience, which provides an empirically testable metatheory and a promising consilient bridge between psychology and the natural sciences. © 2004 Wiley Periodicals, Inc. J Clin Psychol. [source] Subjective Response to Alcohol: A Critical Review of the LiteratureALCOHOLISM, Issue 3 2010Meghan E. Morean Background:, Subjective response to alcohol (SR), which reflects individual differences in sensitivity to the pharmacological effects of alcohol, may be an important endophenotype in understanding genetic influences on drinking behavior and alcohol use disorders (AUDs). SR predicts alcohol use and problems and has been found to differ by a range of established risk factors for the development of AUDs (e.g., family history of alcoholism). The exact pattern of SR associated with increased risk for alcohol problems, however, remains unclear. The Low Level of Response Model (LLR) suggests that high-risk individuals experience decreased sensitivity to the full range of alcohol effects, while the Differentiator Model (DM) asserts that high risks status is associated with increased sensitivity to alcohol's positive effects but decreased sensitivity to negative effects. Aims:, The current paper (1) reviews two prominent models of subjective response, (2) reviews extant laboratory-based research on subjective response, (3) highlights remaining gaps in our understanding and assessment of subjective response, and (4) encourages collaborative efforts to address these methodological and conceptual concerns. Methods:, This paper reviews studies which employed placebo-controlled and non-placebo-controlled alcohol challenge paradigms to assess a range of alcohol effects including impairment, stimulation, and sedation. Results:, The research literature provides at least partial support for both the LLR and DM models. High-risk individuals have been shown to have a reduced response to alcohol with respect to sedative or impairing effects, particularly on the descending limb of the blood alcohol curve (BAC). There is also evidence that ascending limb stimulant effects are more pronounced or operate differently for high-risk individuals. Discussion:, Despite commendable advances in SR research, important questions remain unanswered. Inconsistent results across studies may be attributable to a combination of an inadequate understanding of the underlying construct and methodological differences across studies (e.g., number and timing of assessments across the BAC, inclusion of a placebo condition). With respect to the underlying construct, existing measures fail to adequately distinguish between cognitive/behavioral impairment and sedation, aspects of which may be perceived positively (e.g., anxiolysis) due to their ability to act as negative reinforcers. Conclusions:, Addressing the concerns raised by the current review will be integral to making meaningful scientific progress in the field of subjective response. [source] Experimental design and taxonomic scope of fragmentation studies on European mammals: current status and future prioritiesMAMMAL REVIEW, Issue 2 2010Alessio MORTELLITI ABSTRACT 1Habitat loss, habitat fragmentation and habitat degradation are the greatest threats to mammals in Europe and the rest of the world. Despite the fact that extensive literature exists, no comprehensive review or synthesis is available to date and this may slow down scientific progress and hamper conservation efforts. 2The goal of this study is to understand if and in what direction progress has been made in the study of the effects of habitat loss and fragmentation on the spatial distribution of European terrestrial mammals. Firstly, we carry out a general synthesis which is structured around 11 key points. The aim of this point-by-point analysis is to identify trends, knowledge gaps and any significant bias in the available literature, and to highlight strengths and shortfalls of the different approaches which have to date been applied. Secondly, we follow a species-specific systematic approach: for each species, we synthesise key results. 3Our results show how substantial progress has been hampered for several reasons including: a large predominance of small-scale field studies of short duration, and a generalised lack of control of: (i) confounding variables; (ii) spatial autocorrelation; and (iii) false absences. Also, despite the relatively high number of studies, few were theoretical studies and even fewer were meta-analyses. The lack of meta-analyses is likely to be due to the small amount of crucial details included in the publications, such as model parameters or information on the landscape context (such as the amount of residual forest cover). 4We synthesise the main results for 14 species. The level of progress is highly variable: for some species, such as the red squirrel Sciurus vulgaris, a series of long-term, large-scale process-oriented studies has allowed an in-depth understanding of its ecology in fragmented landscapes. On the other hand, with other species such as the bank vole Myodes glareolus, despite a relatively large number of field studies, little progress has been made.

Carayannis Collaborative, team-based research is now the most significant mode of activity in the global scientific community. Anecdotal and statistical evidence shows moreover that collaboration in scientific research is increasingly global in nature. That is, the groups of researchers who are involved in scientific progress often span one or more nations in origin, location and/or sponsorship. Another significant trend in recent cases of scientific collaboration is the increase in cross-sectoral cooperation, where researchers in a group are employed by government, private industry, and/or academic and other non-profit institutions. In this paper, we review the scale, scope and intensity of cross-national, cross-sectoral research collaboration through the analysis of historical data on co-authorship of scientific publications. The first part of the paper reviews existing literature on the analysis of co-authorship data, and discusses the limitations of this form of analysis and typical strategies to mitigate those limitations. The second part of the paper describes a preliminary study of cross-national, cross-sectoral scientific collaborations covering the years 1988 through 1997, where we examined the scale (volume of co-authored papers), intensity (co-authored papers versus other kinds of co-authorship), and scope (patterns in co-authorship) for cross-national, cross-sectoral collaborations. The conclusion of the paper discusses significant trends and patterns derived from this study, and their implications for further research into these types of collaborations. [source] Teaching & Learning Guide for: Can a Darwinian Be a Christian?RELIGION COMPASS (ELECTRONIC), Issue 3 2008Gregory W. Dawes Author's Introduction The article was provoked by recent discussion of the so-called ,conflict thesis': the idea that the Christian faith and the findings of modern science are necessarily at odds. This thesis is generally attributed to John William Draper (1811,1882) and Andrew Dickson White (1832,1918). Recent opposition to their work dates from a 1979 publication by James Moore. Moore argues that the warfare metaphor employed by Draper and White misrepresents the historical reality, by suggesting that the religion and science debates were clashes between distinct groups of people who were sharply polarized and violently antagonistic. Since then, similar criticisms have been made by historians, such as David Livingstone, Ronald Numbers, and David Lindberg. A key question here is: what does the conflict thesis entail? If it holds that Christian thinkers have invariably opposed scientific progress, while the defenders of science have been non-believers, it would be demonstrably false. But there exist more interesting forms of conflict thesis, which are philosophical rather than historical. These suggest that there is some tension between what Christians have traditionally believed and the findings of modern science, particularly Darwin's theory of evolution by natural selection. Even if the two are not, strictly speaking, incompatible, the truth of one may constitute evidence against the truth of the other. Darwin's theory also undercuts traditional arguments from design, and highlights the epistemological divide between religious and scientific conceptions of authority. Online Materials The following sites contain audio and video files, as well as text and images. 1. http://www.meta-library.net/history/intro-frame.html This is a useful overview of the historical debate by Ronald Numbers, with links to other sites. Most presenters follow Moore in opposing the conflict thesis, narrowly defined, but neglect the conflicts that my article highlights. 2. http://www.pbs.org/wgbh/nova/id/program.html Here one can view an excellent, 2-h PBS television documentary on the Dover, Pennsylvania trial in December 2005 regarding the teaching of ,intelligent design' (ID) in public schools. 3. http://www.butler.edu/clergyproject/rel_evol_sun.htm This is a letter signed by more than 11,000 clergy, arguing that there is no conflict between religion and science, and encouraging (among other things) the liturgical celebration of evolution by natural selection. 4. http://www.discovery.org/csc/ At the other end of the theological spectrum, this is the website of the Discovery Institute, devoted to opposing Darwinism and promoting ,intelligent design' (ID). Controversially, it presents ID as a scientific theory, rather than a religious doctrine. 5. http://www.asa3.org/ Somewhere between the Clergy Letter Project and the Discovery Institute lies the American Scientific Affiliation (ASA). The ASA ,does not take a position when there is honest disagreement between Christians', so it embraces a variety of perspectives. Sample Syllabus The following could form the basis for a graduate seminar on religion and science, focusing on the Darwinian controversies. One could, for instance, devote two classes to each of these topics. 1. The Draper-White Thesis I recommend reading extracts from the two writers thought to be responsible for the conflict thesis, to establish what each actually said. John William Draper, The History of the Conflict between Religion and Science, International Scientific Series 13 (London: Henry S. King & Co., 1875), chap. 8. Andrew Dickson White, A History of the Warfare of Science with Theology in Christendom (1896; New York, NY: Dover Publications, 1960), vol. 1, chap. 1. 2. Criticism of the Draper-White Thesis Either of the following readings from historians critical of Draper and White's work would be a useful starting point for discussion. James R. Moore, The Post-Darwinian Controversies: A Study of the Protestant Struggle to Come to Terms with Darwin in Great Britain and America, 1870,1900 (Cambridge: Cambridge University Press, 1979), chap. 1. David N. Livingstone, ,Re-placing Darwinism and Christianity', in David C. Lindberg and Ronald L. Numbers (eds.), When Science and Christianity Meet, pp. 183,202 (Chicago, IL: University of Chicago Press, 2003). 3. The Incompatibility Thesis Many authors attempt to show that Darwinism and Christianity and compatible. But it would be useful to examine Pope John Paul II's statement on this topic, along with some responses by biologists and philosophers. John Paul II, ,The Pope's Message on Evolution and Four Commentaries', The Quarterly Review of Biology, 72:4 (1997): 375,406. 4. The Evidential Thesis Students might enjoy reading and discussing the following article by a leading evolutionary biologist. George C. Williams, ,Mother Nature Is a Wicked Old Witch', in Matthew H. Nitecki and Doris V. Nitecki (eds.), Evolutionary Ethics, 217,31 (Albany, NY: State University of New York Press, 1993). 5. The Replacement Thesis This is an important but often neglected book. Students would benefit from reading at least the first chapter. Neal C. Gillespie, Charles Darwin and the Problem of Creation (Chicago, IL: University of Chicago Press, 1979), chap. 1. 6. The Faith and Reason Thesis The following article by a well-known historian and philosopher of science touches on some of the key issues. Ernan McMullin, ,Evolution and Special Creation', Zygon 28:3 (1993): 299,335. Focus Questions 1There exist many Christian thinkers who accept Darwin's theory of evolution by natural selection. Does that mean there is no conflict between Darwinism and Christianity? 2Taken at face value, Genesis 1,3 tells the story of the origins of the world and of human beings. What aspects of that story would you consider essential to the Christian faith? 3If we have an entirely natural explanation of the origins of complex living organisms, do we still have reasons to believe in a creator God? 4If God could have created complex living beings by a simple command, why would he choose a lengthy and wasteful process such as natural selection? 5Could a Christian regard the existence of God in the same way as a scientific hypothesis, that is to say, to be accepted only in so far as it is supported by the evidence? Seminar Activity I would suggest a debate, in which students sympathetic to the creationist position are asked to defend Darwin's theory, while students sympathetic to evolution are asked to argue against it. [source] Self-Regulation Research in Work and I/O PsychologyAPPLIED PSYCHOLOGY, Issue 2 2005Ruth Kanfer Les recherches de psychologie industrielle/organisationnelle (I/O) sur les objectifs et l'autorégulation ont prospéré durant les trois dernières décennies. Initiés par le travail fécond de Locke, Latham et de leurs collègues qui ont souligné l'influence positive d'objectifs elairs et sollicitants sur les performances, de nombreux courants de recherche sont apparus pour étudier à la fois les déterminants et les conséquences des objectifs et des processus d'autorégulation sur les conduites et les variables dépendantes relatives au travail (voir par exemple Locke, Shaw, Saari, & Latham, 1981; Vancouver, 2000 pour une revue de questions). Vancouver et Day (2005) constatent que si les chercheurs en organisations ont tenté d'évaluer la validité externe et critérielle, ils se sont moins intéressés à la validité interne et de construction des variables-clés et de concepts tels que les objectifs, la rétroaction, la divergence et l'efficacité personnelle. Dans le même ordre d'idées, Vancouver et Day (2004) concluent que les validations des interventions I/O fondées sur la perspective objectif/autorégulation détectent généralement des effcts positifs, mais que ces travaux sont insuffisants pour déterminer les dimensions spécifiques du processus objectif/autorégulation qui sont en rapport avec l'amélioration de la performance. Dans ce court article, j'aborde ces problèmes concemant la recherche sur les objectifs et l'autorégulation d'un triple point de vue: le progrès scientifique, les applications et les buts des investigations I/O. Over the past three decades, industrial/organisational (I/O) research on goals and self-regulation has flourished. Beginning with the seminal work by Locke, Latham, and their colleagues showing the positive influence of difficult and specific goals on task performance, multiple streams of research have emerged to investigate both the determinants and consequences of goals and self-regulation processes on work-related behaviors and outcomes (see, e.g. Locke, Shaw, Saari, & Latham, 1981; Vancouver, 2000, for reviews). In a review of this work, Vancouver and Day (2005) suggest that although organisational researchers have sought evidence for external and criterion-related validity, less attention has been given to the construct and internal validity of key variables and concepts, such as goals, self-efficacy, feedback, discrepancy, and self-efficacy. In a related vein, Vancouver and Day (2005) conclude that although I/O intervention studies based on the goal/self-regulation perspective show generally positive effects, such studies are insufficient for understanding how specific aspects of the goal/self-regulation process relate to enhanced performance. In this short note, I consider these concerns about goal/self-regulation research in I/O psychology from three perspectives: (1) scientific progress, (2) applications, and (3) the goals of I/O research. [source] Case of the hidden assumptionsBIOCHEMISTRY AND MOLECULAR BIOLOGY EDUCATION, Issue 1 2002Daniel E. Koshland Jr The Ogston "three point attachment" model to explain how proteins discriminate between d and l isomers was originally proposed to explain the asymmetric distribution of isotopes that passed through a symmetric intermediate. It has been a standard in textbooks and the literature until the recent finding of Mesecar and Koshland [6] that it could not explain data of isocitrate dehydrogenase and other enzymes and must be replaced by a "four location model." The hidden assumptions that are part of the Ogston model are seen to be an interesting feature of the scientific method that can both advance and hinder scientific progress. [source] An Embryonic Nation: Life Against Health in Canadian Biotechnological DiscourseCOMMUNICATION THEORY, Issue 1 2005Rebecca Sullivan This article traces the protracted public debate over reproductive and genetic technologies in Canada through an examination of the federal government's efforts to pass legislation in the area. Four attempts were made, in 1997, 2000, 2003, and finally 2004, before a bill was passed that regulated the use of embryos in both infertility treatments and nonreproductive genetic therapies. At stake in the debate was the supremacy of health over life as a fundamental value of Canadian national identity, and the role of biotechnology in ushering Canada into a new era of prosperity and global leadership. Using a feminist cultural framework, the author challenges notions of modernity versus postmodernity in the social construction of bodies, nations, and knowledge. She critiques the legal intrusions on women's bodies in particular for the way that they, perhaps inadvertently, offer some limited form of autonomy for embryos as valuable commodities in scientific progress.
