Abstract The construction industry is one of the most critical activities for the sustainable development of a country, generating positive and negative economic, social and environmental impacts. These aspects can be measured by Sustainability Indicators and Indices, which are useful tools for society, investors and the government in decision-making, especially when purchasing products and services, as they quantify information about a phenomenon in a given dimension of sustainability. Therefore, the objective of this study is to propose a model for assessing the sustainability of civil construction companies, considering economic, social, environmental and corporate governance criteria. These criteria are aggregated into a single index using the PROMETHEE II multicriteria method, which allows to avoid the compensation effect caused by the aggregation operators based on the additive model. The model was used to evaluate four Brazilian construction companies: Alpha, Beta, Delta and Gamma. The data of these companies were collected in a database of the Brazilian Chamber of the Construction Industry and in the sustainability`s reports published by them. We concluded that the companies Alpha and Gamma, followed by the company Beta presented the best performances in corporate sustainability, while the construction company Delta has the worst level of corporate sustainability.

ABSTRACT: Decision-making in protected areas is often difficult due to an unclear definition of management objectives and indicators for their monitoring. This is frequently related to the coexistence of systems of protected areas at national and regional levels for which management objectives are ambiguous or that are not directly related to protected areas classification standards. In this study, we proposed a participative model based on PROMETHEE II to find consensual protected areas categories based on IUCN framework. This model involved the stakeholder’s assessments of management objectives in a protected area and their aggregation based on distance comparisons with objectives of international protected areas standards. The model was tested in the Albufera de Valencia Natural Park, a strongly human-modified wetland located in Eastern Spain and it allowed the identification of consensual management priorities and the IUCN category V as the equivalent international protected area category for this regional protected area.

Purpose The purpose of this paper is to establish the need and the importance of adopting a structured model to support the decisions by using a multicriteria focus to guide drawing up a methodological framework. In addition, this study considers the maturity level of the organization, and the importance of continuous improvement after implementing ISO 9001. Design/methodology/approach This study presents a scientific technical foundation of the qualifying and selection criteria of the consultancy and Accredited Certification Body (ACB) by using ISO standards, and the guidance document CB25, which is related to quality. Finally, a numeric application with realistic data is undertaken using the PROMETHEE II method, and the GAIA plan. Findings The development of this study provides a new insight into the importance for selecting consultancy, and certification services in order to implement quality management systems within organizations. Research limitations/implications The current study is limited to the quality management services. If necessary to apply the same model to other areas, it is necessary looking for documents and regulations of this field. In addition, this model is focussed on a model for small or medium companies, which are still trying to achieve a higher position in the sector, and do not have experts in quality management. Originality/value The differential of this study is the foundation of the criteria for the proposed model. Other studies choose these criteria without any scientific basis. On the other hand, this study goes over many documents.

<p>The electrical distribution network is a critical and complex system in terms of safety and reliability, because it is composed of different components (switches, reclosers, etc.). The improvement of its reliability is therefore one of the most important tasks through the good management of remote-controlled switches and reclosers in this network. This paper presents an analytical model based on graph theory to evaluate SAIDI and SAIFI indices based on the network architecture and the location of remote-controlled reclosers and switches. These indicators have been used to formalize a multi-objective mathematical model that respects the real operation constraints of equipments in smart grid. The applied model, in this article, was evaluated on an IEEE 13 bus network using the TOPSIS method to determine the optimal location of the switches and reclosers and to improve the overall reliability of the distribution network.</p>

Abstract Bayesian decision theory provides a simple formal elucidation of some of the ways that representation and representational abstraction are involved with, and exploit, both prediction and its rather distant cousin, predictive coding. Both model-free and model-based methods are involved.

The extracellular matrix (ECM) plays a critical role in directing cell behaviour and morphogenesis by regulating gene expression and nuclear organization. Using non-malignant (S1) human mammary epithelial cells (HMECs), it was previously shown that ECM-induced morphogenesis is accompanied by the redistribution of nuclear mitotic apparatus (NuMA) protein from a diffuse pattern in proliferating cells, to a multi-focal pattern as HMECs growth arrested and completed morphogenesis . A process taking 10 to 14 days.To further investigate the link between NuMA distribution and the growth stage of HMECs, we have investigated the distribution of NuMA in non-malignant S1 cells and their malignant, T4, counter-part using a novel model-based image analysis technique. This technique, based on a multi-scale Gaussian blur analysis (Figure 1), quantifies the size of punctate features in an image. Cells were cultured in the presence and absence of a reconstituted basement membrane (rBM) and imaged in 3D using confocal microscopy, for fluorescently labeled monoclonal antibodies to NuMA (fαNuMA) and fluorescently labeled total DNA.
