Moral legitimacy in controversial projects and its relationship with social license to operate: a case study

Moral legitimacy entails intrinsic value and helps executives convince firm’s stakeholders and the general public of the ethical acceptability of an institution or its activities or projects. Social license to operate (SLO) is the social approval of those affected by a certain business activity, and it is receiving increasing attention, especially in the context of controversial projects such as mining and public works. Moral legitimacy provides ethical support to SLO. Drawing from the Aristotelian-Thomistic tradition and taking substantive justice and the common good of society as the key references, this paper applies the Triple Font of Morality Theory and proposes four criteria which serve to evaluate moral legitimacy: (1) contribution of the project or activity to the common good in a better way than other alternatives (intended end), (2) morality of the means and procedures employed (means elected), (3) ethical evaluation of the situation including stakeholder concerns and needs (concurrent relevant circumstances), and (4) ethical evaluation of reasonably foreseeable consequences associated with the project and how to minimize possible damage or risks, and balance foreseeable negative consequences and benefits. The application of these criteria is illustrated through a project, presented as a case study, which certainly involved controversy and problems with SLO. The project was the construction of a rail tunnel for a high-speed train near the foundations of the Sagrada Familia, the well-known monumental church in Barcelona, Spain

Sistema integrado para toma de decisiones en el diseño de estructuras de hormigón

This paper presents a methodology to analyze decisions in the design of concrete structures. Specifically, we propose a multi-criteria approach to assess the value implications of precast concrete technologies versus in-situ concrete solutions. First, we emphasize the importance of careful decision-making in early stages of construction projects to enhance customer value. Second, we present a decisionmaking methodology that uses fuzzy logic to represent and synthesize information about risk-return tradeoffs in the different kinds of variables involved in the evaluation of a project’s value. To illustrate, we use our methodology to analyze precast vs. in-situ solutions in the design of drainage structures. The results of our analysis point at precast solutions as the most desirable design choice in this setting, and highlight the importance of value analysis in early stages of construction projects.El presente artículo hace una breve reflexión sobre las alternativas in situ y prefabricadas para estructuras de hormigón, justificando la necesidad de profundizar en métodos multicriterio como ayuda a la toma de decisiones. Manifiesta la trascendencia de la calidad en las decisiones más allá de este ámbito concreto, así como su influencia en la mayor eficiencia de las obras. Presenta luego un sistema de ayuda a la toma de decisiones basado en matemática difusa, que considera el valor de cada alternativa contemplando el riesgo inherente. Para ilustrarlo desarrolla un ejemplo aplicado a pasos inferiores que pueden resolverse mediante prefabricación o in situ. Efectuándolo por completo, llega a dos conclusiones principales: la bondad de la herramienta presentada y cómo la solución prefabricada, en este caso, aporta mayor valor. Concluye también que todo buen gestor debe plantearse su toma de decisión desde los inicios de cualquier proyecto, empleando herramientas como la presentada

Minimizing the social impact of construction work on mobility: a decision-making method

Minimising the impacts of construction work on mobility, especially in urban areas, is a major issue for local authorities and construction planners that has not been sufficiently studied. This paper proposes a deterministic decision-making method for quantifying the impacts of construction work on mobility, including emergency vehicles, mass transit, individual transport, bicycles, and pedestrians. The method is based on multi-attribute utility theory, interviews with experts representing various stakeholders in construction, and a review of the literature and legislation. The practical use is illustrated with a real case study in which two shaft-construction processes (diaphragm wall excavated using a hydromill and vertical shaft sinking machine) are compared and ranked. The sensitivity analysis shows the robustness of the results. The resulting Mobility Impact Index can easily be integrated with other social, economic, and environmental criteria, thereby enabling the evaluation of alternatives from a multi-criteria perspective, e.g., in tender processes. The method could be useful to public authorities and design and construction companies and is being piloted in construction projects of the city of Barcelona. It has implications for corporate social responsibility, social/sustainable procurement, and social/sustainable impact assessment in construction

Integración arquitectónica de colectores solares térmicos cerámicos para clima mediterráneo

The work presented here aims to demonstrate the technical, architectural and energy viability of solar thermal collectors made with ceramic materials and the Mediterranean climate suitable for the production of domestic hot water (DHW) and for heating systems in buildings. The design of a ceramic shell formed by panels collectors and panels no sensors, which are part of the same building system that is capable of responding to the basic requirements of a building envelope and capture solar energy is proposed. Ceramics considerably reduced the final cost of the sensor system and offers the new system a variety of compositional and chromatic since, with reduced performance compared to a conventional metallic collector, can occupy the entire surface of front and get a high degree of architectural integration. A tool for assessing the new ceramic solar collector has been defined from a multi-criteria perspective: economic, environmental and social. The tool enables the comparison of the ceramic solar collector with solar collectors on the market under different climatic and demand conditions.El trabajo aquí presentado se orienta a demostrar la viabilidad técnica, arquitectónica y energética de colectores solares térmicos realizados con materiales cerámicos y adecuados al clima mediterráneo para la producción de agua caliente sanitaria (ACS) y de calefacción en edificios. Se propone el diseño de una envolvente cerámica formada por paneles captadores y paneles no captadores, que forman parte de un mismo sistema constructivo que es capaz de dar respuesta a los requerimientos básicos de un cerramiento exterior y de captar la energía solar. La cerámica consigue reducir considerablemente el coste final del sistema captador y ofrece al nuevo sistema una gran variedad de juego compositivo y cromático dado que, con un menor rendimiento frente al de un colector convencional metálico, puede ocupar toda la superficie de fachada y obtener un elevado grado de integración arquitectónica. También se ha definido una herramienta que permite evaluar el sistema de captación solar térmica cerámico desde un punto de vista multicriterio, económico, ambiental y social, para compararlo con los sistemas de captación solar térmica comerciales bajo distintas condiciones climáticas y de demanda

Sustainability-driven decision-making model: case study of fiber-reinforced concrete foundation piles

Currently, foundation piles for inhabited areas are often constructed using a continuous flight auger, which is a cost- and time-efficient technology that does not require stabilization of the borehole wall; the steel bar reinforcement is embedded after the concrete has been poured. However, this reinforcement operation can lead to severe construction and structural issues. Thus, several improvements to this technology have been proposed since its first application in the 20th century, such as the use of more fluid concretes. Nevertheless, steel and polymers are emerging as a potential replacement for steel bars in concrete reinforcement for several types of structures and building components, with identified and quantified benefits from a sustainability perspective. Accordingly, this paper proposes and validates a multicriteria decision-making approach designed with multidisciplinary experts within the construction field to assess the sustainability index of concrete pile foundations. The results of a case study enable us to conclude that polymeric fiber-reinforced concrete piles are the most sustainable due to their cost–structural efficiency ratio, high durability, and minimal risks during construction. Steel fiber-reinforced concrete alternatives were also found to be more sustainable than traditional reinforced concrete. Nonetheless, these results are unrepresentative of the current practice as direct costs were found to be the main driver in the decision-making processes, while other costs and both environmental and social indicators are disregarded. This justifies the urgency to provide sustainability-driven decision-making approaches capable of objectively quantifying the satisfaction degree of economic, environmental, and social indicators involved in the analysis

Decision-making tool for enhancing the sustainable management of cultural institutions: season content programming at Palau de la música catalana

There has been an increasing relevance of the cultural sector in the economic and social development of different countries. However, this sector continues without much input from multi-criteria decision-making (MDCM) techniques and sustainability analysis, which are widely used in other sectors. This paper proposes an MCDM model to assess the sustainability of a musical institution’s program. To define the parameters of the proposed model, qualitative interviews with relevant representatives of Catalan cultural institutions and highly recognized professionals in the sector were performed. The content of the 2015–2016 season of the ‘Palau de la Música Catalana’, a relevant Catalan musical institution located in Barcelona, was used as a case study to empirically test the method. The method allows the calculation of a season value index (SVI), which serves to make more sustainable decisions on musical season programs according to the established criteria. The sensitivity analysis carried out for different scenarios shows the robustness of the method. The research suggests that more complex decision settings, such as MCDM methods that are widely used in other sectors, can be easily applied to the sustainable management of any type of cultural institution. To the best of the authors’ knowledge, this method was never applied to a cultural institution and with real data

Association between necropsy evidence of disseminated intravascular coagulation and hemostatic variables before death in horses with colic

Background: Disseminated intravascular coagulation (DIC) is frequent in horses with severe gastrointestinal disorders. Postmortem studies have found fibrin microthrombi in tissues of these horses, but studies relating these histopathological findings with antemortem hemostatic data are lacking. Hypothesis: Antemortem classification of coagulopathy is related to the presence and severity of fibrin deposits observed postmortem in horses with severe gastrointestinal disorders. Animals: Antemortem hemostatic profile data and postmortem tissue samples (kidney, lung, liver) from 48 horses with colic. Methods: Tissue samples were stained with phosphotungstic acid hematoxylin and immunohistochemical methods for histological examination. A fibrin score (grades 0-4) was assigned for each technique, tissue and horse, as well as the presence or absence of DIC at postmortem examination. D-dimer concentration, prothrombin time (PT), activated partial thromboplastin time (aPTT), and antithrombin (AT) activity, as well as the clinicopathological evidence of coagulopathy, were determined from plasma samples collected 0-24 hours before death or euthanasia. Histologic and clinicopathologic data from the same horses were compared retrospectively. Results: No association was found between antemortem classification of coagulopathy and postmortem diagnosis of DIC based on tissue fibrin deposition. None of the hemostatic parameters was significantly different between horses with or without postmortem diagnosis of DIC. There was no association between horses with fibrin in tissues or different cut-offs for D-dimer concentration and postmortem evidence of DIC. Conclusions and Clinical Importance: Abnormalities of the routine clotting profile, including D-dimer concentration, were not useful in predicting histologic evidence of DIC at necropsy in horses with severe gastrointestinal disorders

Muerte perinatal: acompañamiento a mujeres y parejas

Objetivo: analizar las intervenciones que llevan a cabo los profesionales para mejorar la atención brindada a las mujeres y a sus parejas ante una pérdida perinatal. Método: es una revisión de la bibliografía internacional publicada en los últimos 10 años sobre intervenciones para mejorar la atención que se brinda a las parejas ante la muerte de un hijo. Resultados: se observa un déficit en la formación de los profesionales sanitarios relacionada con este tema y se identifican nuevas actuaciones cuyo objetivo es mejorar la atención a las parejas. Conclusiones: no podemos concluir que la «creación de recuerdos» mejore los resultados psicosociales, pero sí la información adaptada durante el proceso, y la matrona es la profesional idónea para ello. No obstante, es necesario mejorar la formación y los recursos de los profesionales para poder ofrecer una atención de calidad
