The Cerrado and Amazon regions of Brazil are probably the largest agricultural frontier of the world, and Could be a sink or source for C depending on the net effect of land use change and subsequent management on soil organic C pools. We evaluated the effects of agricultural management systems on soil organic C (SOC) stocks in the Brazilian states of Rondonia and Mato Grosso, and derived regional specific factors for soil C stock change associated with different management systems. We used 50 observations (data points) in this study, including 42 dealing with annual cropping practices and 8 dealing with perennial cropping, and analyzed the data in linear mixed-effect models. No tillage (NT) systems in Cerrado areas increased SOC Storage by 1.08 +/- 0.06 relative to SOC stocks under native conditions, while SOC storage increased by a modest factor of 1.01 +/- 0.17 in Cerradao and Amazon Forest conditions. Full tillage (FT) had negative effect on SOC storage relative to NT, decreasing SOC stocks by a factor of 0.94 +/- 0.04. but did not significantly reduce SOC stocks relative to native levels when adopted in the Cerrado region. Perennial cropping had a minimal impact on SOC stocks, estimated at a factor Value of 0.98 +/- 0.14, suggesting these systems maintain about 98% of the SOC stock found under native vegetation. The results Suggest that NT adoption may be increasing SOC with land use change from native vegetation to cropland management in the Cerrado region of Brazil. (C) 2009 Elsevier B.V.

Grassland management affects soil organic carbon (SOC) content and a variety of management options have been proposed to sequester carbon. However, studies conducted in Brazilian pastures have shown divergent responses for the SOC depending on management practices. Our objective was to evaluate the effects of management on SOC stocks in grasslands of the Brazilian states of Rondonia and Mato Grosso, and to derive region-specific factors for soil C stock change associated with different management conditions. Compared to SOC stocks in native vegetation, degraded grassland management decreased SOC by a factor of 0.91 +/- 0.14, nominal grassland management reduced SOC stock for Oxisols by a relatively small factor of 0.99 +/- 0.08, whereas, SOC storage increased by a factor of 1.24 +/- 0.07 with nominal management for other soil types. Improved grassland management on Oxisols increased SOC storage by 1.19 +/- 0.07, relative to native stocks, but there were insufficient data to evaluate the impact of improved grassland management for other soil types. Using these results, we also evaluated the potential for grassland management to sequester or emit C to the atmosphere, and found that degraded grassland management decreased stocks by about 0.27-0.28 Mg C ha(-1) yr(-1); nominal management on Oxisols decreased C at a rate of 0.03 Mg C ha(-1) yr(-1)...

Wireless Sensor Networks (WSNs) have a vast field of applications, including deployment in hostile environments. Thus, the adoption of security mechanisms is fundamental. However, the extremely constrained nature of sensors and the potentially dynamic behavior of WSNs hinder the use of key management mechanisms commonly applied in modern networks. For this reason, many lightweight key management solutions have been proposed to overcome these constraints. In this paper, we review the state of the art of these solutions and evaluate them based on metrics adequate for WSNs. We focus on pre-distribution schemes well-adapted for homogeneous networks (since this is a more general network organization), thus identifying generic features that can improve some of these metrics. We also discuss some challenges in the area and future research directions. (C) 2010 Elsevier B.V.

People with disabilities have a right to a full life in every sense and one of those fundamental rights is the possibility to work. In this paper, the importance of social employment integration of disabled people is highlighted as one of the stakeholders to be satisfied by companies in the new framework that corporate social responsibility is constructing. The objective of the paper is to revise the benefits of some well-known operations research/management science tools that, if applied correctly, have a double positive impact on work accessibility and improved productivity. The responses collected from managers of Valencia`s ShelteredWork Centres for Disabled by means of a structured questionnaire are used to analyse the level of implementation of these tools and their impact depending on the type of centre, the kind of disability and other structural variables.; Regional Valencian Government (Spain)[GVA 2007-241]; Regional Valencian Government (Spain); CNPq Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (Brazil)[561672/2008-3]; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)

This thesis describes the design, implementation, and execution of the Linear Road benchmark for stream-based data management systems. The motivation for benchmarking and the selection of the benchmark application are described. Test harness implementation is discussed, as are experiences using the benchmark to evaluate the Aurora engine. Effects of this work on the evolution of the Aurora engine are also discussed. Streams consist of continuous feeds of data from external data sources such as sensor networks or other monitoring systems. Stream data management systems execute continuous and historical queries over these streams, producing query results in real-time. This benchmark provides a means of comparing the functionality and performance of stream-based data management systems relative to each other and to relational systems. The benchmark presented is motivated by the increasing prevalence of "variable tolling" on highway systems throughout the world. Variable tolling uses dynamically determined factors such as congestion levels and accident proximity to calculate tolls. Linear Road specifies a variable tolling system for a fictional urban area, including such features as accident detection and alerts, traffic congestion measurements...

In this dissertation, I trace methods for organizing skilled workers engaged in creative, limited-term projects in the United States between the nineteenth century and the 1950s. Examining eras of system building in technical fields-civil engineering in the nineteenth century, laboratory administration in the 1910s and 1920s, aircraft design in the 1930s, and electronics in the 1950s-I show that recent discourse on the management of innovation and change is a manifestation of a cyclically recurring conversation. This story complicates prevalent views of management theory and practice before World War II by recovering a thread obscured by emphasis on the organization of integrated, divisional companies and operative labor within them. Applying ideas from recent work in organization studies to distill common aspects of the management problems and labor processes individuals have confronted and theorized, I find common patterns: managers of construction firms, engineering departments, and research laboratories have again and again theorized the fast-moving, knowledge-intensive, relational organization, doing so long before these terms were available. Such thinking has been driven both by practical needs and because external pressures have forced explanation of seemingly uncontrolled...

(cont.) running simulation. Third, since BCachet is almost linear under the assumption of a reasonable number of sites, BCachet is very scalable. Therefore, it can be used to for very large scale multiprocessor systems.; We propose an efficient buffer management method for Cachet [7], called BCachet. Cachet is an adaptive cache coherence protocol based on a mechanism-oriented memory model called Commit-Reconcile & Fences (CRF) [1]. Although Cachet is theoretically proved to be sound and live, a direct implementation of Cachet is not feasible because it requires too expensive hardware. We greatly reduced the hardware cost for buffer management in BCachet without changing the memory model and the adaptive nature of Cachet. Hardware cost for the incoming message buffer of the memory site is greatly reduced from PxN FIFOs to two FIFOs in BCachet where P is the number of sites and N is the number of address lines in a memory unit. We also reduced the minimum size of suspended message buffer per memory site from (log₂ P+V) xPx(rq[max]), to log₂ P where V is the size of a memory block in terms of bits and rqma is the maximum number of request messages per cache. BCachet has three architectural merits. First, BCachet separates buffer management units for deadlock avoidance and those units for livelock avoidance so that a designer has an option in the liveness level and the corresponding hardware cost: (1) allows a livelock with an extremely low probability and saves hardware cost for fairness control. (2) does not allow a livelock at all and accept hardware cost for fairness control. Second...

The evolution of science has intrigued countless scientists. Many philosophers hold that scientific evolution is linear and constantly adding to the overall body of knowledge. Thomas Kuhn changed this view. In his famous work, The Structure of Scientific Revolutions, he proposes a route to normal science. He explains that paradigm shifts are arduous and require long time periods to occur. Using qualitative research combined with a Kuhnian model, we explain the evolution of Supply Chain Management (SCM) from its origins. Some authors have traced SCM evolution with a focus on chronological and linear order. This paper brings a new approach using Kuhnian elements to explain how SCM has matured to its present form. This broad picture manifests the strenuous path of SCM’s evolution and helps to explain how it is close to becoming a normal science.

Information management is becoming a necessary task for modem research laboratories. As scientific research within a particular domain progresses, the amount of data and publications in the domain increases drastically. Type one diabetes (TID) research is no exception. The DRV (Diabetes Research Vortex) addresses the information management challenge. The DRV's main objective is to provide a web accessible information management system for diabetes related publications and experimental data. The DRV was inspired by current T1D research paradigms. A user can choose to upload a publication or experimental data under one of four research categories: a strain, gene, Idd (Insulin Dependent Diabetic) genetic region, or custom keyword. The effectiveness of the DRV lies in the biological concepts it encapsulates. The DRV allows a user to view the system's contents by browsing a strain, gene, Idd, or custom keyword. Furthermore, the DRV allows a user to seamlessly browse among related strains, genes, and Idd's. The DRV links information between each of these domains and allows a user to intuitively acquire knowledge about a specific interest. The system can also be asked to mine publications from PubMed based the terms stored in the -four aforementioned categories. Furthermore...

The contribution of this thesis is to provide a tractable framework for supply chains and revenue management problems subject to uncertainty that gives insight into the structure of the optimal policy and requires little knowledge of the underlying probability distributions. Instead, we build upon recent advances in the field of robust optimization to develop models of uncertainty that make few probabilistic assumptions and have an adjustable level of conservatism to ensure performance. Specifically, we consider two classes of robust optimization approaches. First, we model the random variables as uncertain parameters belonging to a polyhedral uncertainty set, and optimize the system against the worst-case value of the uncertainty in the set. The polyhedron is affected by budgets of uncertainty, which reflect a trade-off between robustness and optimality. We apply this framework to supply chain management, show that the robust problem is equivalent to a deterministic problem with modified parameters, and derive the main properties of the optimal policy. We also explore a second approach, which builds directly on the historical realizations of uncertainty, without requiring any estimation. In that model, a fraction of the best cases are removed to ensure robustness...

Data projectors are often used in demanding imaging applications requiring accurate color. To properly control the color output of such a device, one needs accurate color control models. This paper will describe a color management algorithm for a four-color DLP projector. Four-channel color displays have only recently been introduced to the market. The displays being examined in this paper have the traditional red, green and blue channels and also a supplemental white channel. In parallel to the four-color printer problem, a fourth channel in a display creates a color reproduction challenge since one XYZ can potentially be mapped to many RGBW combinations. A further complication of these projectors is that at the computer interface they are treated as RGB displays. The conversion from RGB to RGBW takes place internally making them at once compatible with current RGB display signals and yet unfriendly to simple color management approaches. The characterization of a display forms the foundation of a mapping from device digital coordinates to colorimetry. This is referred to as the “ forward model.” A common method for characterizing typical RGB color displays starts with three one-dimensional input look-up tables (LUTs) for linearizing the digital input signals with respect to tristimulus values (XYZ). This is followed by a 3x3 matrix for scalar rotation...

Recent developments in spectral imaging are pointing toward a future where the demands on color management will require a richer infrastructure than that which is currently offered. ICC color management includes a stage where all colors are transformed to and from XYZ-based colorspaces. This colorimetric bottleneck is acceptable within a metameric or Maxwellian approach to color reproduction, but severely undermines the advantages of spectral imaging. Spectralizer, a spectral image visualization tool, has been implemented to provide a platform where spectral images may be easily displayed, manipulated, analyzed and processed. It has proven to be useful in investigating algorithms and prototype datastructures for performing the management of color within a spectral imaging environment.; "Color management within a spectral image visualization tool," Proceedings of the Eighth Color Imaging Conference: Color Science and Engineering Systems, Technologies, Applications.

A deeper knowledge about interpersonal relationships’ dynamics may be extremely useful for organizations. Although studies about interpersonal relationships are not much explored by researchers in management, they may contribute to theoretical advances in contemporary organization management and to the training of professionals in the area. This paper aims at discussing the proposal of Robert Hinde to organize a science of interpersonal relationship and its relevance for organizational studies; it attempts, also, to establish connections between Hinde’s proposal and the area of personnel administration. This theoretical discussion was based on Robert Hinde’s works dedicated to personal relationships, on some classic works in management science and on a parcel of the production of contemporary organizational studies. The concepts and ideas organized by Hinde as a theoretical framework for a science of relationships have been identified and presented and links between Hinde’s proposal and contemporary organizational studies have been discussed. It is suggested that Hinde’s proposal is extremely useful as a theoretical framework to guide research in personal relationships, in management research and also for professional training in the area.; Conhecimentos mais profundos sobre a dinâmica dos relacionamentos interpessoais podem ser extremamente relevantes para as organizações.

The Census Bureau recently conducted a survey of management practices in over 30,000 plants across the US, the first large-scale survey of management in America. Analyzing these data reveals several striking results. First, more structured management practices are tightly linked to higher levels of IT intensity in terms of a higher expenditure on IT and more on-line sales. Likewise, more structured management is strongly linked with superior performance: establishments adopting more structured practices for performance monitoring, target setting and incentives enjoy greater productivity and profitability, higher rates of innovation and faster employment growth. Second, there is a substantial dispersion of management practices across the establishments. We find that 18% of establishments have adopted at least 75% of these more structured management practices, while 27% of establishments adopted less than 50% of these. Third, more structured management practices are more likely to be found in establishments that export, who are larger (or are part of bigger firms), and have more educated employees. Establishments in the South and Midwest have more structured practices on average than those in the Northeast and West. Finally, we find adoption of structured management practices has increased between 2005 and 2010 for surviving establishments...

Ambiguity, the existence of multiple plausible (though possibly contested) ways of making sense of the characteristics of decision situations, can present significant difficulties for a wide range of risk management tasks. We will argue that ambiguity is present in risk management situations to a far greater extent that is commonly appreciated. The concept of ambiguity has arisen in different forms across disciplinary literatures and domains of practice. In this paper, we situate our experience of finding ways of supporting planning and decision-making processes concerned with ambiguous risks in the context of those wider perspectives. Our own efforts have employed a hybrid form of problem structuring methods (drawn from operational research and management science) and ethnography (drawn from sociology and anthropology). These engagements with organisational and inter-organisational risk management issues have led us to recognise that ‘untangling’ otherwise intractable risk management problems may be regarded, in some sense, as a therapeutic process. In this paper, we develop this therapeutic interpretation of the untangling of collective ambiguities using illustrations from a concrete problem situation. We set this therapeutic reading of decision processes in the context of wider perspectives...

This thesis examines and exposes the work of one of the most enigmatic of capitalist institutions – the management consultancy – as that of financialisation. In recent decades financial markets have played an increasingly important role in the operations of the global economy, which has led to fundamental changes to managerial practices of the modern corporation. In particular, many authors, from a variety of disciplines within social sciences, have discussed the ascendancy of shareholder value as the ideology of corporate governance. But what is rarely examined is how shareholder value has been disseminated and installed as a corporate good. At the same time, there continues to be widespread ignorance about one of the major proponents of shareholder value – management consultancies. In short, we still do not know what consultancies do. I attempt to address this lacuna by examining how management is practised within management consultancy. Through an ethnography based on 16 months of fieldwork inside one of the world’s largest management consultancies, I show that shareholder value is an ethic of production which has to be made through a set of sociotechnical practices which are deployed in the pursuit of an ontological transformation – the enactment of the corporation as a financial asset. I highlight the importance of information technology (IT) in this endeavour...
