The Diffusion of Management Innovations: The Possibilities and Limitations of Memetics

JOURNAL OF MANAGEMENT STUDIES, Issue 8 2007
Joseph O'Mahoney
abstract This paper applies a theory of memetics to help explain the diffusion of management innovations as a dynamic evolutionary process. Existing analyses of diffusion frequently note the variation, selection or replication of management innovations, yet few have linked these together with the common observation that some innovations seem to ,evolve'. This paper draws on qualitative evidence from two case-studies of BPR implementation to illustrate that the replication, selection and variation of management innovations can form evolutionary algorithms (,memes') which support diffusion processes, and, in doing so, clarifies the ways in which innovations contribute to their own replication and explains how the high ,failure' rates associated with BPR can sometimes improve its chances of reproduction.

Responding to Roommate Troubles: Reconsidering Informal Dyadic Control

LAW & SOCIETY REVIEW, Issue 3 2008
Robert M. Emerson
Existing analyses of informal control within dyadic relations neglect the nonpenal responses that characterize many such control efforts, and they give minimal attention to the interactional and interpretive processes that characterize such responses. And while dispute transformation provides a well-developed model of the development of dyadic disputes, this model is limited in prespecifying "injury" as the starting point for these processes and in neglecting informal reactions other than "claiming." Integrating theories of informal control and dispute transformation, this article provides a case study analyzing the nature and processes of informal reactions to troubles involving college roommates, identifying three general categories of such response: managerial reactions, which involve unilateral, nonconfrontational efforts to manage the consequences or implications of the trouble or to change indirectly the troubling behavior; complaint-making reactions, where the troubled party attempts to get the other to change the disturbing behavior; and distancing and punitive reactions, which are relationally despairing responses marked by open confrontation and hostility.

Extracting long-term patterns of population changes from sporadic counts of migrant birds

ENVIRONMETRICS, Issue 5 2010
Joanna Mills Flemming
Abstract Declines of many North American birds are of conservation concern. For almost 40 years, experienced birders have kept daily counts of migrant landbirds during visits to Seal and Brier Islands, both of which are off Nova Scotia's southern tip. Here we assess the utility of Generalized Additive Models (GAMs) to extract patterns of population change of a common migrant to Seal Island, the Ruby-crowned Kinglet, while controlling for other influences including season, weather and effort. We also demonstrate, using counts of the Kinglet from Brier Island as well as counts of another common migrant, the Yellow-rumped Warbler, how our GAM methods can combine data from different geographic areas or distinct species. Most existing analyses of similar long-term data sets have used linear models to estimate trends. Our results and comparisons suggest that GAMs are a powerful way of extracting more information from such data. Copyright © 2009 John Wiley & Sons, Ltd. [source]

Mechanics of land subsidence due to groundwater pumping

INTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS, Issue 14 2010
Muniram Budhu
Abstract This paper presents the formulation of the basic mechanics governing the changes in stress states from groundwater pumping and comparisons among predicted land subsidence from this mechanics with existing analyses and field data. Land subsidence is a growing, global problem caused by petroleum and groundwater withdrawal, mining operations, natural settlement, hydro-compaction, settlement of collapsible soils, settlement of organic soils and sinkholes. This paper is concerned with the land subsidence due to groundwater level decline by groundwater pumping. It is shown that the stress state consists of asymmetric stresses that are best simulated by a Cosserat rather than a Cauchy continuum. Land subsidence from groundwater level decline consists of vertical compression (consolidation), shear displacement and macro-rotation. The latter occurs when conditions are favorable (e.g. at a vertical interface) for the micro-rotation imposed by asymmetric stresses to become macro-rotation. When the length of the cone of depression is beyond ,2 times the thickness of the aquifer, simple shear on vertical planes with rotation is the predominant deformation mode. Otherwise, simple shear on horizontal planes is present. The predicted subsidence using the mechanics developed in this paper compares well with data from satellite-borne interferometric synthetic aperture radar. Copyright © 2009 John Wiley & Sons, Ltd.

Permanent-transitory Decomposition in Var Models With Cointegration and Common Cycles

OXFORD BULLETIN OF ECONOMICS & STATISTICS, Issue 4 2000
Alain Hecq
In this paper we derive permanent-transitory decompositions of non-stationary multiple times series generated by (r)nite order Gaussian VAR(p) models with both cointegration and serial correlation common features. We extend existing analyses to the two classes of reduced rank structures discussed in Hecq, Palm and Urbain (1998). Using the corresponding state space representation of cointegrated VAR models in vector error correction form we show how decomposition can be obtained even in the case where the number of common feature and cointegration vectors are not equal to the number of variables. As empirical analysis of US business fluctuations shows the practical relevance of the approach we propose. [source]

OpenUH: an optimizing, portable OpenMP compiler

CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 18 2007
Chunhua Liao
Abstract OpenMP has gained wide popularity as an API for parallel programming on shared memory and distributed shared memory platforms. Despite its broad availability, there remains a need for a portable, robust, open source, optimizing OpenMP compiler for C/C++/Fortran 90, especially for teaching and research, for example into its use on new target architectures, such as SMPs with chip multi-threading, as well as learning how to translate for clusters of SMPs. In this paper, we present our efforts to design and implement such an OpenMP compiler on top of Open64, an open source compiler framework, by extending its existing analysis and optimization and adopting a source-to-source translator approach where a native back end is not available. The compilation strategy we have adopted and the corresponding runtime support are described. The OpenMP validation suite is used to determine the correctness of the translation. The compiler's behavior is evaluated using benchmark tests from the EPCC microbenchmarks and the NAS parallel benchmark. Copyright © 2007 John Wiley & Sons, Ltd. [source]

Restructuring Uganda's Coffee Industry: Why Going Back to Basics Matters

DEVELOPMENT POLICY REVIEW, Issue 4 2006
John Baffes
After experiencing a boom during the mid-1990s, the performance of Uganda's coffee industry has been disappointing. Most existing analysis sees the sector's problems as quality deterioration, a poor marketing position in the global market, a weak regulatory framework, and poor infrastructure. Recommendations range from setting up a coffee auction to increasing the share of specialty coffees. This article concludes that such advice has been largely inconsistent with the stylised facts of the Uganda coffee industry, and it argues that coffee wilt disease and the effectiveness of the coffee replanting programme are the two key issues on which policymakers and the donor community should focus their activities and allocate their resources.
