The new challenges of the manufacturing industry applying the norm ISO 45001:2018

The present work reflects the impact that the manufacturing industries must solve in the application of the ISO 45001: 2018 Standard on Occupational Health and Safety Management Systems. In such, a globalized market where human and material assets must be preserved for the survival of organizations, management systems based on continuous improvement play an important role in ensuring compliance with applicable legal requirements, risk management and the opportunities, as well as the achievement of the best working conditions. The manufacturing industry has not been alien to this evolution; the nature of the risks present in the different industries, the operations carried out, the machinery, the use of work teams and their processes make this sector a priority and strategic sector that should be at the forefront of new technologies and rules. The implementation of the ISO 45001: 2018 standard in the manufacturing industry is a challenge for the implementation of high-level management systems that guarantee a healthy and safe environment for workers and a strategic and operational decision from the business point of view based on improving the performance of health and safety at work and increasing competitiveness in an increasingly demanding market.Universidad de Málaga.

Strategic Consensus in Top Management Teams: The Role of Status Hierarchy, Firm Performance, and a Culture of Dissent

Status hierarchies influence all human interactions, including strategic consensus in top management teams. In this conceptual paper, we articulate why strategic consensus in top management teams is likely to be more a reflection of compliance of low-status top managers with high-status top managers’ judgments than a genuine team’s agreement on the firm’s strategic priorities. We theorize how a firm’s performance can restrain and drive change in status hierarchies, thus impacting the persistence and dissolution of strategic consensus. We also articulate how a culture of dissent can minimize the impact of status hierarchies on strategic consensus. Our model has some implications for examining diversity in top management teams. Scholars have long emphasized the importance of diversity in top management teams, arguing that managers with different backgrounds and viewpoints make firms better equipped to face competitive challenges. However, status hierarchies remind us that if top managers’ ideas and contributions are weighed by their status, organizations might not easily realize the potential benefits of having a diverse top management team

Sistema de visualización para un entorno avanzado de desarrollo de software

El Proyecto Lope se concibe como un Proyecto de Investigación en el campo de los entornos avanzados de desarrollo de Software. Este tipo de entornos trata de cubrir buena parte de las actividades que comprenden el ciclo de vida del software, yendo por lo tanto mucho mas allá de las tareas de programación. Una de las ideas clave del proyecto es que define realmente un metaentorno, o entorno para definir entornos de desarrollo, ya que resulta lo suficientemente abierto como para poder implementar dentro lo que un entorno necesite: compilador de cualquier lenguaje, editores, herramientas gráficas. . .Es decir, no fuerza el uso de ninguna metodología de desarrollo ni lenguaje de programación: son aspectos totalmente configurables por el usuario. Este trabajo desarrolla uno de los subsistemas básicos del prototipo del metaentorno Lope: el Subsistema de Visualización. Este subsistema se diseña con la idea de poder representar cualquier información que maneje el Sistema, de cualquier manera posible, ya sea textual o gráfica; si bien en este trabajo quedan pendientes de estudio las primitivas gráficas. El documento de este trabajo se ha organizado en los siguientes capítulos: 1. Entornos de desarrollo de software, donde se realiza una introducción a los entornos de desarrollo en sus diversas variantes. 2. El Entorno Lope, donde se describe en líneas generales todo el Sistema en el que se enmarca este trabajo. 3. Las Ideas generales sobre el subsistema de visualización se exponen en este capítulo, sirviendo de introducción a la comprensión del elemento principal: el formato. 4. Los Ejemplos de formatos que se exponen aquí complementan al capítulo anterior con el objetivo de afianzar los conceptos descritos. 5. Las Características de la implementación se describen aquí en profundidad, explicando estructuras de datos, algoritmos, etc., utilizados. 6. El Ejemplo de utilización describe un programa de prueba con el objetivo de dar ideas al lector sobre como podrían construirse herramientas en la capa de edición de Lope. 7. Finalmente, se incluye todo el código fuente implementado

Convergence of level sets in fractional Laplacian regularization

The use of the fractional Laplacian in image denoising and regularization of inverse problems has enjoyed a recent surge in popularity, since for discontinuous functions it can behave less aggressively than methods based on $H^1$ norms, while being linear and computable with fast spectral numerical methods. In this work, we examine denoising and linear inverse problems regularized with fractional Laplacian in the vanishing noise and regularization parameter regime. The clean data is assumed piecewise constant in the first case, and continuous and satisfying a source condition in the second. In these settings, we prove results of convergence of level set boundaries with respect to Hausdorff distance, and additionally convergence rates in the case of denoising and indicatrix clean data. The main technical tool for this purpose is a family of barriers constructed by Savin and Valdinoci for studying the fractional Allen-Cahn equation. To help put these fractional methods in context, comparisons with the total variation and classical Laplacian are provided throughout.Comment: 33 pages, 1 figur

Reynolds number and Shallow Depth Sloshing

The dependence on the Reynolds number of shallow depth sloshing flows inside rectangular tanks subjected to forced harmonic motion is studied in this paper with weakly compressible SPH. We are interested in assessing the in fluenceof viscous effects on the dynamics of shallow depth sloshing flows by using an SPH solver and by comparing with a Navier-Stokes level-set solver results. The goal of trying to model these viscous flows is compromised by the resolution requested due to their Reynolds number, if boundary layer effects are to be modeled. The convenience and feasibility of the implementation of free-slip and no-slip boundary conditions is also discusse

Biomimetic flow fields for proton exchange membrane fuel cells: A review of design trends

Bipolar Plate design is one of the most active research fields in Polymer Electrolyte Membrane Fuel Cells (PEMFCs) development. Bipolar Plates are key components for ensuring an appropriate water management within the cell, preventing flooding and enhancing the cell operation at high current densities. This work presents a literature review covering bipolar plate designs based on nature or biological structures such as fractals, leaves or lungs. Biological inspiration comes from the fact that fluid distribution systems found in plants and animals such as leaves, blood vessels, or lungs perform their functions (mostly the same functions that are required for bipolar plates) with a remarkable efficiency, after millions of years of natural evolution. Such biomimetic designs have been explored to date with success, but it is generally acknowledged that biomimetic designs have not yet achieved their full potential. Many biomimetic designs have been derived using computer simulation tools, in particular Computational Fluid Dynamics (CFD) so that the use of CFD is included in the review. A detailed review including performance benchmarking, time line evolution, challenges and proposals, as well as manufacturing issues is discussed.Ministerio de Ciencia, Innovación y Universidades ENE2017-91159-EXPMinisterio de Economía y Competitividad UNSE15-CE296

The Relationship Between Teachers’ Art Experiences And Their Attitudes Towards The Importance Of Art Education In An International School In Bangkok, Thailand

The purpose of this research was to identify teachers’ art experiences, as well as their attitudes towards the importance of art education, and subsequently determine the relationship between teachers’ experiences and their attitudes. The research focused on teachers from the primary level of an international school in Bangkok, Thailand. A questionnaire was used to gather information about teachers’ past art experiences as a student in primary, secondary school and university, as an adult and as related to family. Findings revealed that teachers value their art experiences in primary and secondary school as somewhat positive, while it was deemed neutral in university. A gradual change was also observed in the results regarding how teachers rated the importance of art education: from somewhat positive in primary and secondary school, to neutral in university. Correlation analyses further confirmed that there was indeed a significant relationship between teachers’ art experiences and their attitudes towards the importance of art education, particularly as a student
