Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

A review on circular economy: the expected transition to a balanced interplay of environmental and economic systems

Analytic hierarchy process : An overview of applications

This chapter discusses leading problems linked to energy that the world is now confronting and to propose some ideas concerning possible solutions. Oil deserves special attention among all energy sources. Since the beginning of 1981, it has merely been continuing and enhancing the downward movement in consumption and prices caused by excessive rises, especially for light crudes such as those from Africa, and the slowing down of worldwide economic growth. Densely-populated oil-producing countries need to produce to live, to pay for their food and their equipment. If the economic growth of the industrialized countries were to be 4%, even if investment in the rational use of energy were pushed to the limit and the development of nonpetroleum energy sources were also pursued actively, it would be extremely difficult to prevent a sharp rise in prices. It is evident that it is absolutely necessary to pursue actively the development of coal, natural gas, and nuclear power if a physical shortage of energy is not to block economic growth.

Models that depict innovation as a smooth, well-behaved linear process badly misspecify the nature and direction of the causal factors at work. Innovation is complex, uncertain, somewhat disorderly, and subject to changes of many sorts. Innovation is also difficult to measure and demands close coordination of adequate technical knowledge and excellent market judgment in order to satisfy economic, technological, and other types of constraints—all simultaneously. The process of innovation must be viewed as a series of changes in a complete system not only of hardware, but also of market environment, production facilities and knowledge, and the social contexts of the innovation organization.

Adoption of water reuse technologies: An assessment under different regulatory and operational scenarios.

The mutual interdependences between safety and operations: A systematic literature review

The growing complexity of modern society is fostering great attention to the issue of the continuity of critical services and related infrastructures. The underlying processes and physical components of a specific service delivery (e.g. electric power or water) reveal many dependencies both technical and non technical. The paper presents an integrated methodology for vulnerability and resilience analysis for underground infrastructures, i.e. a societal risk analysis of the failures of underground services for an urban area. Based on the use of a hybrid approach, the proposed methodology breaks down the area under analysis into sub-areas and assesses the dependencies among sub-areas both in terms of interoperability, damage propagation of critical infrastructures and target zoned-description. The methodology demonstrates clear advantage in terms of resilience analysis, more consistent with the “zoned” nature of failures of the underground infrastructures. A case study, dealing with the interoperability and damage propagation analysis of the underground infrastructures of a Northern Italy town, will be presented for this purpose. A resilience analysis of the “system of systems” (i.e. multiple underground infrastructures) can be performed through the proposed methodology, evaluating the internal characteristics of the system able to mitigate or amplify the impact of local failures and thus the capability to assure service continuity after such failures. Finally a strategy for risk mitigation is proposed in order to maintain the minimum level of service.

Towards an Integrated Vulnerability and Resilience Analysis for Underground Infrastructures

A multitude of Occupational Health and Safety (OHS) interventions have proven to be effective under controlled conditions, but their implementation in practice is often difficult and interventions may therefore not work as expected, especially when referring to Small and Medium sized Enterprises (SMEs). In order to solve this challenge, this paper proposes a model for the systematic design of OHS interventions which takes into account the underlying mechanisms and the contextual factors which can hamper or further the implementation of interventions. in-depth analysis of context and mechanism, and on the other hand in keeping it sufficiently simple for utilisation in the practical situation. This paper aims at providing a solution for this practitioners’ challenge by proposing a model for the design of Occupational Safety and Health (OHS) interventions which takes into account the contextual factors and the behavioural mechanisms affecting the implementation of the intervention. The paper is structured as follows. In paragraph 2 (background), the literature related to implementation of interventions is briefly presented, with a focus on the realistic analysis and its limitations, which generated the research work. In paragraph 3, (the model), we present the model. In paragraph 4, the results of the test of the model in 20 Italian manufacturing firms are presented. Finally, in paragraph 5 some conclusions are taken.
