Selected AbstractsENDOSCOPIC MANAGEMENT OF BILIARY and PANCREATIC DUCTS STRICTURESDIGESTIVE ENDOSCOPY, Issue 2004Hiroyuki Maguchi ABSTRACT Endoscopic treatment is applied to a relatively large number of biliary and pancreatic duct strictures, and is a practical matter. It is essential to select the most appropriate treatment for each lesion. For instance, when treating malignant biliary stricture, accurate diagnosis of whether surgical treatment is required or not is vital; and in choosing a stent for an inoperable case, location of the stricture, with or without anticancer treatment, prognosis, and management of possible post-stenting re-stricture must be taken into consideration. For benign strictures, not only short-term results in mobility and motality, but also decades of long-term results must be cautiously questioned. Bearing these in mind, we need to accumulate the worldwide data of the treatments and establish a proper treatment guideline. [source] Experimental Research and the Managerial Attitude: a tension to be resolved?EUROPEAN JOURNAL OF EDUCATION, Issue 3 2008MARTIN BENNINGHOFF This article analyses some typical consequences of a specific research policy on experimental research in biology. The policy is conducted by a national funding agency , the Swiss National Science Foundation , through a particular programme, the ,National Centres of Competence in Research' which is designed to promote both ,scientific excellence'and,managerial professionalism'. To study the possible tension between the two objectives, as a practical matter for researchers, the proposed analysis focuses on the interaction between two laboratory scientists and the administrators of a genomic platform. Access to the instruments of this platform is granted through a preliminary interview with those in charge of the platform. During that interview, researchers are required to explain why they want to use the platform services and what their expectations concerning their envisaged activities are. A tape-recorded interview is analysed in order to describe how turns at talking by the various parties, as well as the formulation of the problems encountered by a researcher, prove category-bound. The first part of the meeting (,problem exposition') is structured by the categorical device ,generalist researcher vs. specialist researcher', whilst the second part (,problem solving') is organised by the categorical device ,manager vs. user of the platform'. The ,scientific' problem becomes a ,technical' one and the choice of technique is partly based on financial reasons. The situation shows how managerial injunctions of research policy are not without practical consequences for research activities in situ. [source] METHODS FOR JOINT INFERENCE FROM MULTIPLE DATA SOURCES FOR IMPROVED ESTIMATES OF POPULATION SIZE AND SURVIVAL RATESMARINE MAMMAL SCIENCE, Issue 3 2004Daniel Goodman Abstract Critical conservation decisions often hinge on estimates of population size, population growth rate, and survival rates, but as a practical matter it is difficult to obtain enough data to provide precise estimates. Here we discuss Bayesian methods for simultaneously drawing on the information content from multiple sorts of data to get as much precision as possible for the estimates. The basic idea is that an underlying population model can connect the various sorts of observations, so this can be elaborated into a joint likelihood function for joint estimation of the respective parameters. The potential for improved estimates derives from the potentially greater effective sample size of the aggregate of data, even though some of the data types may only bear directly on a subset of the parameters. The achieved improvement depends on specifics of the interactions among parameters in the underlying model, and on the actual content of the data. Assuming the respective data sets are unbiased, notwithstanding the fact that they may be noisy, we may gauge the average improvement in the estimates of the parameters of interest from the reduction, if any, in the standard deviations of their posterior marginal distributions. Prospective designs may be evaluated from analysis of simulated data. Here this approach is illustrated with an assessment of the potential value in various ways of merging mark-resight and carcass-survey data for the Florida manatee, as could be made possible by various modifications in the data collection protocols in both programs. [source] Finding Commercially Attractive User Innovations: A Test of Lead-User Theory,THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 4 2006Nikolaus Franke Firms and governments are increasingly interested in learning to exploit the value of lead-user innovations for commercial advantage. Improvements to lead-user theory are needed to inform and to guide these efforts. The present study empirically tests and confirms the basic tenets of lead-user theory. It also uncovers some new refinements and related practical applications. Using a sample of users and user,innovators drawn from the extreme sport of kite surfing, an analysis was made of the relationship between the commercial attractiveness of innovations developed by users and the intensity of the lead-user characteristics those users display. A first empirical analysis is provided of the independent effects of its two key component variables. In the empirical study of user modifications to kite-surfing equipment, it was found that both components independently contribute to identifying commercially attractive user innovations. Component 1, the high expected-benefits dimension, predicts innovation likelihood, and component 2, the ahead of the trend dimension, predicts both the commercial attractiveness of a given set of user-developed innovations and innovation likelihood due to a newly proposed innovation supply side effect. It was concluded that the component variables in the lead-user definition are indeed independent dimensions, so neither can be dropped without loss of information,an important matter for lead-user theory. It also was found that adding measures of users' local resources can improve the ability of the lead-user construct to identify commercially attractive innovations under some conditions. The findings reported here have practical as well as theoretical import. Product modification and development has been found to be a relatively common user behavior in many fields. Thus, from 10 to nearly 40 percent of users report having modified or developed a product for in-house use in the case of industrial products or for personal use in the case of consumer products in fields sampled to date. As a practical matter, therefore, it is important to find ways to selectively identify the user innovations that manufacturers will find to be the basis for commercially attractive products in the collectivity of user-developed innovations. The implications of these findings for theory as well as for practical applications of the lead-user construct are discussed,that is, how variables used in lead-user studies can profitably be adapted to fit specific study contexts and purposes. [source] Social development: the intellectual heritageJOURNAL OF INTERNATIONAL DEVELOPMENT, Issue 7 2003James Midgley Because social development is primarily concerned with practical matters, little attention has been paid to the ideas, concepts and theories that inform social development interventions. Most publications on social development make little reference to theoretical issues, and most practitioners are unaware of the conceptual derivation of their activities. However, although seldom recognized or acknowledged, social development practice has, in a subtle and indirect way, been informed and shaped by a variety of intellectual ideas that, in turn, reveal a commitment to different normative perspectives. This paper traces the contribution these perspectives have made to social development over the years. By documenting this intellectual heritage, it hopes to promote a greater awareness of theoretical issues and, at the same time, to foster social development's conceptualization.

[source] THE SPIRIT OF DEMOCRACY AND THE RHETORIC OF EXCESSJOURNAL OF RELIGIOUS ETHICS, Issue 1 2007Jeffrey Stout ABSTRACT If militarism violates the ideals of liberty and justice in one way, and rapidly increasing social stratification violates them in another, then American democracy is in crisis. A culture of democratic accountability will survive only if citizens revive the concerns that animated the great reform movements of the past, from abolitionism to civil rights. It is crucial, when reasoning about practical matters, not only to admit how grave one's situation is, but also to resist despair. Therefore, the fate of democracy depends, to some significant degree, on how we choose to describe the crisis. Saying that we have already entered the new dark ages or a post-democratic era may prove to be a self-fulfilling prophecy, because anyone who accepts this message is apt to give up on the hard work of organizing and contestation that is needed to hold political representatives accountable to the people. This paper asks how one might strike the right balance between accuracy and hope in describing the democracy's current troubles. After saying what I mean by democracy and what I think the current threats to it are, I respond to Romand Coles's criticisms of reservations I have expressed before about rhetorical excess in the works of Stanley Hauerwas, Alasdair MacIntyre, and Richard Rorty. This leads to a discussion of several points raised against me by Hauerwas. A digression offers some of my reasons for doubting that John Howard Yoder's biblical scholarship vindicates Hauerwas's version of pacifism. The paper concludes by arguing that Sheldon Wolin's work on the evisceration of democracy, though admirably accurate in its treatment of the dangers posed by empire and capital, abandons the project of democratic accountability too quickly in favor of the romance of the fugitive.
