Bottom-up Process (bottom-up + process)
Selected AbstractsClustering: An Essential Step from Diverging to ConvergingCREATIVITY AND INNOVATION MANAGEMENT, Issue 1 2007Marc Tassoul Within the context of new product development processes and the Creative Problem Solving (CPS) process, the authors have come to the view that clustering is to be seen as a separate step in the process of diverging and converging. Clustering is generally presented as part of the converging stages, and as such categorized as a selection technique, which in the authors' view does not do justice to this activity. It is about expanding knowledge, about connecting ideas, and connecting ideas to problem statements, functionalities, and values and consequences. It is about building a shared understanding, in other words about ,making sense', an essential creative activity in the development of concepts and, although different from a more freewheeling divergent phase, can be as creative and maybe even more so. Four kinds of clusterings are distinguished: object clustering, morphological clustering, functional clustering and gestalt clustering. Object clustering is mainly aimed at categorizing ideas into an overviewable set of groups of ideas. No special connections are being made, other then looking for similarities. Morphological clustering is used to split up a problem into subproblems after which the ideas generated are considered as subsolutions which can then be combined into concepts. Functional clustering is interesting when different approaches can be chosen to answer some question. It permits a more strategic choice to be made. Gestalt clustering is a more synthesis like approach, often with a more metaphoric and artistic stance. Collage is a good example of such clustering. General guidelines for clustering are: use a bottom-up process of emergence; postpone early rationalisations and verbalisations; start grouping ideas on the basis of feeling and intuition; and use metaphoric names to identify clusters. [source] Participation in Urban Contention and DeliberationINTERNATIONAL JOURNAL OF URBAN AND REGIONAL RESEARCH, Issue 3 2010HILARY SILVER Abstract Participation is a popular buzzword in contemporary urban studies. For some, it implies a deepening of democratic deliberation; for others, it represents grassroots resistance to powerful elites and neoliberalization. Rather than seeing participation as either consensus-building or conflicts of interest, as either a top-down or bottom-up process, the evidence suggests that it can be all of these. By adopting a more dynamic, pragmatic, and empirically informed perspective, seemingly opposite normative conceptions of democratic participation may be theorized as different ,moments' in the democratic process. Bottom-up mobilization may coincide with and complement top-down initiatives, each dominating different political phases of policymaking, implementation and monitoring. Case studies from Belfast, Berlin, Durban, Philadelphia and São Paulo illustrate the approach and provide insight into the urban as a social laboratory in which other scales of social life and multiple ways to perform democracy are constructed. Résumé La participation est un terme qui revient très souvent dans les études urbaines contemporaines. Pour certains, elle implique une réflexion démocratique approfondie, pour d'autres, une résistance des citoyens face à la puissance des élites et au néolibéralisme. Si la participation peut être vue comme un moyen de bâtir des consensus ou l'expression de conflits d'intérêts, ou comme un processus imposé par le haut ou bien par la base, les faits suggèrent qu'elle peut être tout cela. En adoptant une perspective pragmatique plus dynamique reposant sur des éléments empiriques, des concepts normatifs de la participation apparemment opposés sont susceptibles d'être formulés en tant que "moments" différents du processus démocratique. La mobilisation par la base peut venir en coïncidence et complément d'initiatives imposées par le haut, chaque forme dominant des phases politiques distinctes dans la prise de décision, la mise en ,uvre et le suivi. Des études de cas portant sur Belfast, Berlin, Durban, Philadelphie et São Paulo illustrent la démarche et font apparaître l'urbain comme un laboratoire où s'élaborent d'autres dimensions de la vie sociale et de multiples modalités d'exercice de la démocratie. [source] Multiple organizational identification levels and the impact of perceived external prestige and communication climateJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 2 2007Jos Bartels Earlier studies have shown that perceived external prestige and communication climate influence organizational identification. In this paper we present the results of a study of the influence of communication climate and perceived external prestige on organizational identification at various organizational levels of a regional police organization. In total, 314 respondents filled out a questionnaire on communication climate, perceived external prestige and organizational identification. The results of this study show that communication climate has the strongest link with employee identification when it concerns the identification with the daily work group and a weaker one with the organization as a whole. It also appears that perceived external prestige has a stronger influence on the identification with the organization as a whole than on the identification at the more concrete organizational levels (such as department or work group). This research offers reasons to presuppose that organizational identification and communication climate are multiple constructs. If management wishes to influence organizational identification through a bottom-up process, it is wise to pay particular attention to the communication climate in the work groups. Influencing organizational identification with the organization as a whole is better conducted through perceived external prestige. Copyright © 2006 John Wiley & Sons, Ltd. [source] Executive Clemency or Bureaucratic Discretion?PRESIDENTIAL STUDIES QUARTERLY, Issue 3 2007Two Models of the Pardons Process This article examines the use of the president's pardon power from 1953 to 2000. Two different models are used to describe the pardons process: a presidential model and an agency model. The presidential model takes a top-down approach to the pardons process by viewing the pardon power as a resource that the president can use to advance specific policy goals. In contrast, the agency model views the pardons process as a bottom-up process, with the preferences of officials within the Department of Justice as the key determinant of the number of pardons issued. This article empirically tests both of these models and finds that the president's control over the pardons process is limited by officials within the Justice Department and the actions of past presidents. This is illustrated by an in-depth case study of President Bill Clinton's controversial use of the pardon power. [source] Functional neural correlates of mindfulness meditations in comparison with psychotherapy, pharmacotherapy and placebo effect.ACTA NEUROPSYCHIATRICA, Issue 3 2010Is there a link? Chiesa A, Brambilla P, Serretti A. Functional neural correlates of mindfulness meditations in comparison with psychotherapy, pharmacotherapy and placebo effect. Is there a link? Objective: Mindfulness meditations (MM) are a group of meditation practices which are increasingly receiving attention. The aim of the present work is to review current findings about the neural correlates of MM and compare such findings with other specific and non-specific treatments. Methods: A literature search was undertaken using MEDLINE, ISI web of knowledge, the Cochrane database and references of retrieved articles. Studies which focused on the functional neural correlates of MM, psychotherapy, pharmacotherapy and placebo published up to August 2009 were screened in order to be considered for the inclusion. Results: Main findings suggest that long-term MM practice allows a more flexible emotional regulation by engaging frontal cortical structures to dampen automatic amygdala activation. A large overlap exists between cerebral areas activated during MM, psychotherapy, pharmacotherapy and those activated by placebo. However, while MM, psychotherapy and placebo seem to act through a top-down regulation, antidepressants seem to act through a bottom-up process. Conclusion: MM seem to target specific brain areas related to emotions and emotional regulation. Similar mechanisms have been observed also in other interventions, particularly psychotherapy. [source] Engineering Nanoassemblies of PolysaccharidesADVANCED MATERIALS, Issue 28 2010Soheil Boddohi Abstract Polysaccharides offer a wealth of biochemical and biomechanical functionality that can be used to develop new biomaterials. In mammalian tissues, polysaccharides often exhibit a hierarchy of structure, which includes assembly at the nanometer length scale. Furthermore, their biochemical function is determined by their nanoscale organization. These biological nanostructures provide the inspiration for developing techniques to tune the assembly of polysaccharides at the nanoscale. These new polysaccharide nanostructures are being used for the stabilization and delivery of drugs, proteins, and genes, the engineering of cells and tissues, and as new platforms on which to study biochemistry. In biological systems polysaccharide nanostructures are assembled via bottom-up processes. Many biologically derived polysaccharides behave as polyelectrolytes, and their polyelectrolyte nature can be used to tune their bottom-up assembly. New techniques designed to tune the structure and composition of polysaccharides at the nanoscale are enabling researchers to study in detail the emergent biological properties that arise from the nanoassembly of these important biological macromolecules. [source] Large-scale ecology and hydrology: an introductory perspective from the editors of the Journal of Applied EcologyJOURNAL OF APPLIED ECOLOGY, Issue 2000S.J. Ormerod 1. Five key features characterize large-scale factors in ecology: (a) they incorporate some of the most major of all ecological phenomena , the ranges of organisms, patterns of diversity, variations in ecosystem character and environmental processes such as climate, biogeochemical cycles, dispersal and migration; (b) they involve interactions across scales through both top-down and bottom-up processes; (c) they are multifaceted, and hence require an interdisciplinary perspective; (d) they reflect the cumulative effects of anthropogenic change across all scales, and so have direct relevance to environmental management; (e) they invariably exceed the range of classical ecological experiments, and so require alternative approaches to hypothesis testing. 2. Against this background, a recent research initiative on large-scale ecology and hydrology was funded jointly by the Natural Environment Research Council (NERC) and the Scottish Executive Rural Affairs Department (SERAD). Outputs from this programme are reported in this special issue of the Journal of Applied Ecology, and they illustrate some of the ecological research that is currently in progress in the UK at large spatio-temporal scales. 3. The spatial scales investigated in the papers range from hectares to whole continents, and much of the work reported here involves modelling. Although the model outputs are intrinsically valuable, several authors express the need for improved validation and testing. We suggest that this is an area requiring much development, and will need considerable innovation due to the difficulties at the scales involved (see 1d). Possible methods include: model applications to new circumstances; large-scale environmental manipulations; large-scale surveys that mimic experimental protocols; support from process studies at smaller scales. These alternatives are not mutually exclusive, and all can allow robust hypothesis testing. 4. Much of the work reported here is interdisciplinary linking, for example, geographical, mathematical, hydrological, hydrochemical and ecological concepts (see 1c). We suggest that even stronger links between environmental disciplines will further aid large-scale ecological research. 5. Most important in the context of the Journal of Applied Ecology, the work reported in this issue reveals that large-scale ecology already has applied value. Sectors benefiting include the conservation of biodiversity, the control of invasive species, and the management of land and water resources. 6. Large-scale issues continue to affect many applied ecologists, with roughly 30,40% of papers published in the Journal of Applied Ecology typically confronting such problems. This special issue adds to the growing body of seminal contributions that will add impetus to further large-scale work. Moreover, occurring in a period when other areas of biology are increasingly reductionist, this collection illustrates that, at least with respect to large-scale environmental problems, ecology still holds centre ground. [source] Beyond top-down and bottom-up work redesign: Customizing job content through idiosyncratic dealsJOURNAL OF ORGANIZATIONAL BEHAVIOR, Issue 2-3 2010Severin Hornung Two established approaches to work redesign are formal top-down interventions and proactive bottom-up job crafting. Top-down approaches are limited in their ability to create individually optimized work characteristics, whereas bottom-up processes are constrained by the latitude workers have to modify their own jobs. Following recent research on the idiosyncratic deals (i-deals) individuals negotiate with their employer, task i-deals customizing job content are suggested as a third approach to work redesign. Hypotheses on antecedents and consequences of task i-deals were tested in two studies conducted in the United States and Germany using structural equation modeling. LMX related positively to the extent of successfully negotiated task i-deals, which, in turn, was associated with a more positive evaluation of work characteristics,specifically, higher complexity and control and lower stressors. Work characteristics mediated positive indirect effects of task i-deals on employee initiative and work engagement. Denied requests for task i-deals were associated with a more negative assessment of work characteristics. We conclude with theoretical, practical, and research implications for better understanding and implementing work redesign through i-deals. Copyright © 2010 John Wiley & Sons, Ltd.
