Capability maturity models for offshore organisational management
The goal setting regرایگان!
The goal setting regime imposed by the UK safety regulator has important implications for an organisation’s ability to manage health and safety related risks. Existing approaches to safety assurance based on risk analysis and formal safety assessments are increasingly considered unlikely to create the step change improvement in safety to which the offshore industry aspires and alternative approaches are being considered. One approach, which addresses the important issue of organisational behaviour and which can be applied at a very early stage of design, is the capability maturity model (CMM). The paper describes the development of a design safety capability maturity model, outlining the key processes considered necessary to safety achievement, definition of maturity levels and scoring methods. The paper discusses how CMM is related to regulatory mechanisms and risk based decision making together with the potential of CMM to environmental risk management.
Capacity withholding equilibrium in wholesale electricity markets
This paper is a quanرایگان!
This paper is a quantitative study of the capacity withholding incentives in the deregulated wholesale electricity markets and resulting price spikes. For the analysis we used an N-player Nash equilibrium model based on marginal cost functions of the generating firms assuming completely inelastic industry demand and complete information. The current results show that in the case of continuous marginal costs the withholding incentive always exists and the total withholding increases with the increase of the curvature of marginal cost functions and the extent of heterogeneity of the generating firms. The discrete form of real marginal cost functions imposes certain restrictions on the withholding. The analysis shows that there exists a threshold level of market demand below which no withholding occurs and above which the withholding becomes beneficial. The curvature and heterogeneity of marginal cost functions also affect the level of this threshold. The model is applied to the power generation in California ISO area.
Capital structure: professional management guidance
Purpose – Capital stرایگان!
Purpose – Capital structure decisions rely on a complex array of theoretical foundations and practical considerations. At the managerial level, it is impractical to base decisions purely on theory. While one can develop a perception of an optimal capital structure, the decision is often obscured by practical limitations to the theoretical base. In order to be useful to practicing managers, policies and decision techniques need to be efficiently accomplished and based on available information. This paper seeks to provide that practical framework. Design/methodology /approach – This paper recounts the simple theoretical base for capital structure, highlights some of the problems encountered when applying the theory to reality, and suggests a framework for practical managerial decisions about capital structure. This exposition is especially useful in undergraduate business curricula, in particular for finance majors considering professional management as a career. Findings – While application of traditional capital structure theory is often impractical, numerous tools are available for use by professional managers to make informed decisions about capital structure. Practical implications – The conclusions from this paper provide a framework for current and prospective professional managers for making appropriate capital structure decisions in their management careers. Social implications – Proper managerial techniques and considerations for leverage and capital structure can potentially benefit society through more prudent use of debt, based on the variety of measures presented in this paper. Originality/value – Topics discussed in this paper have been in development since the 1950s. The contribution of this paper is the creation of a framework for understanding and applying these topics, for pedagogical and management training purposes.
Central Government Accounting and Financial Reporting: a Comparison between France, Italy and the European Union
In recent years, manرایگان!
In recent years, many countries have undertaken reforms of their governmental accounting and financial reporting systems, at central level as well as at local level, in order to meet transparency, accountability and comparison needs. Furthermore, the International Public Sector Accounting Standards Board issued the first set of accounting
standards specifically dedicated to the public sector; but the adoption of these standards is not compulsory,
so not all public sector reforms are based on them

Chameleon: A Resource Scheduler in A Data Grid Environment
Grid computing is moرایگان!
Grid computing is moving into two ways. The Computational Grid focuses on reducing execution time of applications that require a great number of computer processing cycles. The Data Grid provides the way to solve large scale data management problems. Data intensive applications such as High Energy Physics and Bioinformatics require both Computational and Data Grid features. Job scheduling in Grid has been mostly discussed from the perspective of computational Grid. However, scheduling on Data Grid is just a recent focus of Grid computing activities. In Data Grid environment, effective scheduling mechanism considering both computational and data storage resources must be provided for large scale data intensive applications. In this paper, we describe new scheduling model that considers both amount of computational resources and data availability in Data Grid environment. We implemented a scheduler, called Chameleon, based on the proposed application scheduling model. Chameleon shows performance improvements in data intensive applications that require both large number of processors and data replication mechanisms. The results achieved from Chameleon are presented .
Characterization and Identification of Gas Hydrate Bearing Sediments of Oman Sea Using Seismic Methods
Gas hydrates attractرایگان!
Gas hydrates attracted worldwide attention due to their potential as huge energy resource in the recent decades. Therefore identifying and prospecting them is essential for strategic hydrocarbon reservoir management. Seismic methods are known as a powerful gas hydrate exploration methodology. In this research pre-stack seismic attributes have been used to identify elastic properties and qualitative hydrate saturation of sediments. Using AVO analysis on pre-stack seismic data, occurrence of gas hydrate has been confirmed in the Oman Sea. Also post-stack seismic meta-attributes (applying pattern recognition and classification methods on several attribute planes) have been successfully used to make separation between hydrate and non-hydrate sediments. Joint use of pre- and post-stack seismic attributes will be a good evaluation techniques for confirmation of this study.
Characterization of Nanocrystals Using Spectroscopic Ellipsometry
First applications oرایگان!
First applications of ellipsometry to the measurement of poly- and nanocrystalline thin films date back to many decades. The most significant step towards the ellipsometric investigation of composite thin films was the realization of the first spectroscopic ellipsometers in the ’70s , which allowed the measurement of the dielectric function, the imaginary part of which is directly related to the joint density of electronics states sensitively depending upon the changes of the crystal structure. The first models were based on the effective medium approach using constituents of known dielectric functions , whereas the volume fraction of the components can be related to the crystal properties of the thin films. This approach is popular ever since, based on its robustness.
Characterization of poly(vinyl chloride) powder produced by emulsion polymerization
The effect of emulsiرایگان!
The effect of emulsion process formulation ingredients on the morphology, structure, and properties of polyvinyl chloride (PVC) powder has been considered in this study. PVC powder was extracted with ethanol and films were obtained by solvent casting from tetrahydrofurane. Characterization of powders, films, and ethanol extract was performed through FTIR spectroscopy, DSC, AFM, SEM, EDX analysis, methylene blue, and nitrogen adsorption. PVC powder was composed of spheres of a large particle size range from 10 nm to 20 lm as shown by SEM. The specific surface area of the PVC powder was determined as 16 and 12 m2 g-1 from methylene blue adsorption at 25 C and from N2 adsorption at -196 C, respectively. AFM indicated the surface roughness of the films obtained by pressing the particles was 25.9 nm. Density of PVC powder was determined by helium pycnometry as 1.39 g cm-3. FTIR spectroscopy indicated that it contained carbonyl and carboxylate groups belonging to additives such as surface active agents, plasticizers, and antioxidants used in production of PVC. These additives were 1.6% in mass of PVC as determined by ethanol extraction. EDX analysis showed PVC particles surfaces were coated with carbon-rich materials. The coatings had plasticizer effect since, glass transition temperature was lower than 25 C for PVC powder and it was 80 C for ethanol extracted powders as found by using differential scanning calorimetry. These additives from polymerization process made PVC powder more thermally stable as understood from Metrom PVC thermomat tests as well.

chemical cleaning agents and bonding to glass-fiber posts
The inﬂuence of chemرایگان!
The inﬂuence of chemical cleaning agents on the bond strength between resin cement and glass-fber posts was investigated. The treatments included 10% hydroﬂuoric acid, 35% phosphoric acid, 50% hydrogen peroxide, acetone, dichloromethane, ethanol, isopropanol, and tetrahydrofuran. Flat glass-fber epoxy substrates were exposed to the cleaners for 60 s. Resin cement cylinders were formed on the surfaces and tested in shear. All treatments provided increased bond strength compared to untreated control specimens. All failures were interfacial. Although all agents improved the bond strength, dichloromethane and isopropanol were particularly effective.
