Selected AbstractsSupply Chain Strategy, Product Characteristics, and Performance Impact: Evidence from Chinese Manufacturers,DECISION SCIENCES, Issue 4 2009Yinan Qi ABSTRACT Supply chain management has become one of the most popular approaches to enhance the global competitiveness of business corporations today. Firms must have clear strategic thinking in order to effectively organize such complicated activities, resources, communications, and processes. An emerging body of literature offers a framework that identifies three kinds of supply chain strategies: lean strategy, agile strategy, and lean/agile strategy based on in-depth case studies. Extant research also suggests that supply chain strategies must be matched with product characteristics in order for firms to achieve better performance. This article investigates supply chain strategies and empirically tests the supply chain strategy model that posits lean, agile, and lean/agile approaches using data collected from 604 manufacturing firms in China. Cluster analyses of the data indicate that Chinese firms are adopting a variation of lean, agile, and lean/agile supply chain strategies identified in the western literature. However, the data reveal that some firms have a traditional strategy that does not emphasize either lean or agile principles. These firms perform worse than firms that have a strategy focused on lean, agile, or lean/agile supply chain. The strategies are examined with respect to product characteristics and financial and operational performance. The article makes significant contributions to the supply chain management literature by examining the supply chain strategies used by Chinese firms. In addition, this work empirically tests the applicability of supply chain strategy models that have not been rigorously tested empirically or in the fast-growing Chinese economy. [source] Global factors shaping the future of food aid: the implications for WFPDISASTERS, Issue 2007Daniel Maxwell Food aid is a key component of a humanitarian response but its use in other programming contexts is subject to numerous criticisms. Even in humanitarian emergencies food aid is often late, unreliable and out of proportion to other elements of the response. Three major factors will shape the future of food aid. First, mechanisms of food aid governance are being reviewed and may undergo major changes,particularly the Food Aid Convention now that hopes have diminished for an Agreement on Agriculture at the World Trade Organisation. The second significant factor is donor agency trends. Overall levels of food aid have dropped fairly steadily in recent decades and there are several discernible trends in resource allocation, procurement and the use of food aid. The third factor is an emerging body of best practice that will define acceptable standards of food aid programming in the future. [source] A role of local signalling in the establishment and maintenance of the asymmetrical architecture of a neuronJOURNAL OF NEUROCHEMISTRY, Issue 3 2007Eun-Mi Hur Abstract Significant progress has been made in the identification of intrinsic and extrinsic factors involved in the development of nervous system. It is remarkable that the establishment and maintenance of the asymmetrical architecture of a neuron is coordinated by a limited repertoire of signalling machineries. However, the details of signalling mechanisms responsible for creating specificity and diversity required for proper development of the nervous system remain largely to be investigated. An emerging body of evidence suggests that specificity and diversity can be achieved by differential regulation of signalling components at distinct subcelluar localizations. Many aspects of neuronal polarization and morphogenesis are attributed to localized signalling. Further diversity and specificity of receptor signalling can be achieved by the regulation of molecules outside the cell. Recent evidence suggests that extracellular matrix molecules are essential extrinsic cues that function to foster the growth of neurons. Therefore, it is important to understand where the signalling machineries are activated and how they are combined with other factors in order to understand the molecular mechanism underlying neuronal development. [source] Sensory nerve conduction deficit in experimental monoclonal gammopathy of undetermined significance (MGUS) neuropathyMUSCLE AND NERVE, Issue 6 2001Michael W. Lawlor BS Abstract An emerging body of evidence from in vitro studies and in vivo animal models supports a pathogenic role of antibodies in the development of peripheral neuropathy associated with monoclonal gammopathy of undetermined significance (MGUS). Although the assessment of motor and sensory nerve fiber function is of clinical importance, it is seldom applied experimentally. We describe the application of an electrophysiologic method for the evaluation of motor and sensory nerve fiber function using an experimental model of MGUS neuropathy. Supramaximal stimulation of the tibial nerve elicited an early motor response (M-wave, 1.7 ± 0.1 ms, n = 10) and a late sensory (H-reflex, 7.8 ± 0.1 ms, n = 10) response that was recorded from the hind foot of anesthetized rats. Intraneural injection of serum antibodies from a MGUS patient with sensorimotor polyneuropathy, but not from an age-matched control subject, produced a marked attenuation of the H-reflex (P < 0.01, n = 10) without affecting the M-wave. Light and electron microscopy of affected nerve showed myelinoaxonal degeneration with sparing of the smaller unmyelinated nerve fibers. The combined electrophysiologic and morphologic findings presented in this study are consistent with a selective sensory conduction deficit in MGUS neuropathy. Selective injury of afferent nerve fibers by this patient's serum antibodies may result from reactivity to neural antigens uniquely expressed by sensory neurons. © 2001 John Wiley & Sons, Inc.

It focuses on the practices through which the fieldwork role is accomplished and the ,identity work' of nurse ethnographers. Insights derived from ethnomethodology are utilized in order to analyse selected aspects of real-life field experiences in order to enhance our understanding of this relatively neglected dimension of the research process. The article is offered as a contribution to an emerging body of scholarship that is directed at promoting a more rigorous and theoretically informed understanding of the conduct and reportage of ethnographic fieldwork. [source] PERSPECTIVE: Establishing an NPD Best Practices FrameworkTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 2 2006Kenneth B. Kahn Achieving NPD best practices is a top-of-mind issue for many new product development (NPD) managers and is often an overarching implicit, if not explicit, goal. The question is what does one mean when talking about NPD best practices? And how does a manager move toward achieving these? This article proposes a best practices framework as a starting point for much-needed discussion on this topic. Originally presented during the 2004 Product Development Management Association (PDMA) Research Conference in Chicago, the article and the authors' presentation spurred a significant, expansive discussion that included all conference attendees. Given the interest generated, the decision was made to move forward on a series of rejoinders on the topic of NPD best practice, using the Kahn, Barczak, and Moss framework as a focal launching point for these rejoinders. A total of five rejoinders were received and accompany the best practices framework in this issue of JPIM. Each rejoinder brings out a distinct issue because each of the five authors has a unique perspective. The first rejoinder is written by Dr. Marjorie Adams-Bigelow, director of the PDMA's Comparative Performance Assessment Study (CPAS), PDMA Foundation. Based on her findings during the CPAS study, Adams comments on the proposed framework, suggesting limitations in scope. She particularly points out discrepancies between the proposed framework and the framework offered by PDMA's emerging body of knowledge. Dr. Elko Kleinschmidt, professor of marketing and international business at McMaster University, wrote the second rejoinder. Based on his extensive research with Robert G. Cooper on NPD practices, he points out that best practices really raise more questions than answers. Thomas Kuczmarski, president of Kuczmarski and Associates, is the author of the third rejoinder. Kuczmarski highlights that company mindset and metrics are critical elements needing keen attention. Where do these fit,or should they,in the proposed framework? The fourth rejoinder is written by Richard Notargiacomo, consultant for the integrated product delivery process at Eastman Kodak Company. Notargiacomo compares the proposed framework to a best practices framework Kodak has used for new product commercialization and management since 1998. The distinction of the Kodak framework is the inclusion of a product maturity model component. Dr. Lois Peters, associate professor at Rensselaer Polytechnic Institute (RPI), is the author of the fifth rejoinder. She brings out issues of radical innovation, a natural focal issue of RPI's radical innovation project (RRIP). It is highlighted that radical innovation may require unique, distinctive process characteristics a single framework cannot illustrate. Multiple layers of frameworks may be more appropriate, each corresponding to a level of innovation desired. The overall hope is that the discourse on best practices in this issue of JPIM generates more discussion and debate. Ultimately, the hope is that such discourse will lead to subsequent continued study to help discern what NPD best practice means for our discipline. [source] Commercial Insurance vs Community-based Health Plans: Time for a Policy Option With Clinical Emphasis to Address the Cost SpiralTHE JOURNAL OF RURAL HEALTH, Issue 2 2005Bruce Amundson MD ABSTRACT: The nation continues its ceaseless struggle with the spiraling cost of health care. Previous efforts (regulation, competition, voluntary action) have included almost every strategy except clinical. Insurers have largely failed in their cost-containment efforts. There is a strong emerging body of literature that demonstrates the relationship between various clinical strategies and reductions in utilization and costs. This article describes the organization of health services, including integration of delivery and financing systems, at the community level as a model that effectively addresses the critical structural flaws that have frustrated control of costs. Community-based health plans (CHPs) have been developed and have demonstrated viability. The key elements of CHPs are a legal organizational structure, a full provider network, advanced care-management systems, and the ability to assume financial risk. Common misconceptions regarding obstacles to CHP development are the complexity of the undertaking, difficulty assuming the insurance function, and insured pools that are too small to be viable. The characteristics of successful CHPs and 2 case studies are described, including the types of advanced care-management systems that have resulted in strong financial performance. The demonstrated ability of CHPs to establish financial viability with small numbers of enrollees challenges the common assumption that there is a fixed relationship between health plan enrollment size and financial performance. Organizing the health system at the community/regional level provides an attractive alternative model in the health-reformdebate. There is an opportunity for clinical systems and state and federal leaders to support the development of community-based integrated delivery and financing system models that, among other advantages, have significant potential to modulate the pernicious cost spiral. [source] Complex interactions among mammalian carnivores in Australia, and their implications for wildlife managementBIOLOGICAL REVIEWS, Issue 3 2005Alistair S. Glen ABSTRACT Mammalian carnivore populations are often intensively managed, either because the carnivore in question is endangered, or because it is viewed as a pest and is subjected to control measures, or both. Most management programmes treat carnivore species in isolation. However, there is a large and emerging body of evidence to demonstrate that populations of different carnivores interact with each other in a variety of complex ways. Thus, the removal or introduction of predators to or from a system can often affect other species in ways that are difficult to predict. Wildlife managers must consider such interactions when planning predator control programmes. Integrated predator control will require a greater understanding of the complex relationships between species. In many parts of the world, sympatric species of carnivores have coexisted over an evolutionary time scale so that niche differentiation has occurred, and competition is difficult to observe. Australia has experienced numerous introductions during the past 200 years, including those of the red fox (Vulpes vulpes) and the feral cat (Felis catus). These species now exist in sympatry with native mammalian predators, providing ecologists with the opportunity to study their interactions without the confounding effects of coevolution. Despite an increasing body of observational evidence for complex interactions among native and introduced predators in Australia, few studies have attempted to clarify these relationships experimentally, and the interactions remain largely unacknowledged. A greater understanding of these interactions would provide ecologists and wildlife managers world-wide with the ability to construct robust predictive models of carnivore communities, and to identify their broader effects on ecosystem functioning. We suggest that future research should focus on controlled and replicated predator removal or addition experiments. The dingo (Canis lupus dingo), as a likely keystone species, should be a particular focus of attention. [source] | ||||||||||||||||
