The number of accidents and victims in the construction sector has not decreased significantly despite the increasingly stricter laws and regulations. The analysis of accidents, as well as their root causes and determinants can certainly contribute to the development of more effective preventive interventions. The present study proposes a methodology for the analysis and synthesis of data provided by accidents statistics with the goal of defining specific risk profiles based on the accidents determinants, their variables, and how they interact with one another in influencing the occurrence of an accident. For this purpose, a procedure capable of extracting this type of information from the European Statistics on Accidents at Work (ESAW) database was developed. In particular, data processing and aggregation are performed by means of the synergic use of the Matrix of Descriptors (MoD) and cluster analysis. To validate such a procedure, the analysis of fatalities due to electrical shocks was carried out. The results achieved allowed us to elicit valuable information for both safety managers and decision makers. The proposed methodology can facilitate a systemic analysis of accidents databases reducing the difficulties in managing reports and accident statistics.

AbstractThe introduction of the electric energy in more and more diverse applications currently represents an evolution which is considered normal, taking into account the durable development concept, which are required among the decision makers, and also due to the fact that the oil and gas resources are not evenly distributed in the world, and those who do not have these resources look for solutions to provide them a certain independence over those who have resources. One of the technical solutions, available on Earth, is currently represented by the renewable energy sources. Their usage in the field of the electric automobile charging, is both an economic and technical challenge. Technical solutions are available, and they are developing, but their industrial application is related to an economic strategic approach and a systemic one, which are treated below.

Information Technologies represent a primary instrument in all types of organizations. However, their use is not always well planned in the public sector. The research proposes a methodology to build a realistic action plan that improves the use of information technology and its governance in public organizations. We conduct a case study using semi-structured interviews to investigate the different views of 8 decision-makers regarding the use of IT and its governance. The findings were analyzed systematically and synthesized into a set of perspectives on the subject. An interference matrix reveals how each view interferes and receives positive and/or negative interference from the others. Based on the matrix, the methodology applies criteria to prioritize the perspectives with the highest potential to improve the use of IT and its governance. The final product of the methodology is an action plan aligned with the vision of the institution’s decision-makers. The plan requires little effort to improve the use of IT and its governance. Seventeen views related to the use of IT and its governance emerged from the interviews. Four views that do not cause or receive harmful interference from other perspectives were selected to guide the plan elaboration. The methodology proved to be efficient for creating an action plan adapted to the institutional reality. According to the managers, the action plan represents with high precision the most urgent needs of the organization, respecting its work capacity and available resources for a project to improve the use of IT and its governance.

Matrix Game with Payoffs RepresentedDue to the complexity of information or the inaccuracy of decision-makers’ cognition, it is difficult for experts to quantify the information accurately in the decision-making process. However, the integration of the fuzzy set and game theory provides a way to help decision makers solve the problem. This research aims to develop a methodology for solving matrix game with payoffs represented by triangular dual hesitant fuzzy numbers (TDHFNs). First, the definition of TDHFNs with their cut sets are presented. The inequality relations between two TDHFNs are also introduced. Second, the matrix game with payoffs represented by TDHFNs is investigated. Moreover, two TDHFNs programming models are transformed into two linear programming models to obtain the numerical solution of the proposed fuzzy matrix game. Furthermore, a case study is given to to illustrate the efficiency and applicability of the proposed methodology. Our results also demonstrate the advantage of the proposed concept of TDHFNs.

Abstract Community forest managers would benefit from a decision-making procedure that would help them weigh management alternatives and select one that best contributes to their goals. A matrix technique that uses a system of rating and weighing alternative impacts was applied to the decision-making process on the Rye Town Forest in Rye, NH. Using the results of a comprehensive multiple-use inventory of the forest and a survey of residents' preferences for uses of the forest, the matrix procedure aided in selecting a preferred management strategy. It encourages a systematic and objective comparison of preselected management alternatives and allows decision-makers to efficiently analyze and compare new alternatives. North. J. Appl.

Purpose The purpose of this paper is to present an approach based on the thinking process of the theory of constraints (TP–TOC) to support decision-makers, managers and professionals of health to diagnose and improve healthcare systems focusing on the service quality deployed to patients. Design/methodology/approach A case study was developed in a SUS-affiliated philanthropic hospital in southern Brazil, through the analysis of its ED processes and application of the TP–TOC. The Current Reality Tree and the Evaporating Cloud tools of the TOC were used to identify the root causes (RC) and their connections with undesirable effects. Findings The analysis of this case helped to understand and identify the causes of the current problems in the analyzed processes related to internal management and external causes. The proposed approach allowed the hospital team to progress in the understanding of such causes in a sequential manner, giving conditions to apport different perceptions and to identify relevant facets and causes related to the problem. The research provided a systemic and an integrated vision of the losses in the organizational processes and indicated the steps to be prioritized in order to eliminate such losses. Originality/value The paper proposed an approach that allowed the systematic and systemic analysis of organizational processes through the application of the TP–TOC. The recognition of the existence of RC responsible for processes losses represents an excellent opportunity for improvement because it allows managers to focus their efforts on the more productive areas.

Subject. This article deals with the issues relating to improving integrated reporting in terms of dovetailing strategic objectives with capital changes. Objectives. The article aims to develop a system of indicators for disclosure of capital types in integrated reporting of electricity generating companies, as well as recommendations aimed at implementing the fundamental concepts and guiding principles of integrated reporting. Methods. For the study, we used the methods of analysis and synthesis, comparison, generalization, and abstraction. As a case study, we conduct a comparative analysis of the disclosure of six types of capital by the largest electricity generating companies, namely PAO Inter RAO, AO Rosenergoatom and PAO RusHydro. Results. The article formulates proposals for disclosure of capital information to address such a lack of accountability as a contradiction to the principle of coherence. It proposes a system of indicators (core and additional) for disclosure of six types of capital by electricity generating companies. Conclusions. A significant reporting problem is the lack of correlation between key strategic objectives and capital changes. The formulated recommendations for disclosure of capital information can help solve this problem, and increase the attractiveness of the integrated report for capital providers.

Abstract The Kaluza-Klein (KK) decomposition of higher-dimensional gravity gives rise to a tower of KK-gravitons in the effective four-dimensional (4D) theory. Such massive spin-2 fields are known to be connected with unitarity issues and easily lead to a breakdown of the effective theory well below the naive scale of the interaction. However, the breakdown of the effective 4D theory is expected to be controlled by the parameters of the 5D theory. Working in a simplified Randall-Sundrum model we study the matrix elements for matter annihilations into massive gravitons. We find that truncating the KK-tower leads to an early breakdown of perturbative unitarity. However, by considering the full tower we obtain a set of sum rules for the couplings between the different KK-fields that restore unitarity up to the scale of the 5D theory. We prove analytically that these are fulfilled in the model under consideration and present numerical tests of their convergence. This work complements earlier studies that focused on graviton self-interactions and yields additional sum rules that are required if matter fields are incorporated into warped extra-dimensions.

Hydropower Planning

Mitigating climate change, while human population and economy are growing globally, requires a bold shift to renewable energy sources. Among renewables, hydropower is currently the most economic and efficient technique. However, due to a lack of impact assessments at the catchment scale in the planning process, the construction of hydropower plants (HPP) may have unexpected ecological, socioeconomic, and political ramifications in the short and in the long term. The Vjosa River, draining parts of Northern Greece and Albania, is one of the few predominantly free-flowing rivers left in Europe; at the same time its catchment is identified an important resource for future hydropower development. While current hydropower plants are located along tributaries, planned HPP would highly impact the free-flowing main stem. Taking the Vjosa catchment as a case study, the aim of this study was to develop a transferable impact assessment that ranks potential hydropower sites according to their projected impacts on a catchment scale. Therefore, we integrated established ecological, social, and economic indicators for all HPP planned in the river catchment, while considering their capacity, and developed a ranking method based on impact categories. For the Vjosa catchment, ten hydropower sites were ranked as very harmful to the environment as well as to society. A sensitivity analysis revealed that this ranking is dependent upon the selection of indicators. Small HPP showed higher cumulative impacts than large HPP, when normalized to capacity. This study empowers decision-makers to compare both the ranked impacts and the generated energy of planned dam projects at the catchment scale.
