Preventive maintenance versus cost of repairs in asset management: An efficiency analysis in wastewater treatment plants
2020
Abstract The operation and management of Wastewater Treatment Plants (WWTPs) is of paramount importance to guarantee the sustainability of water resources. Just like any other production process, wastewater treatment process involves different costs, such as: energy, personnel, maintenance and reagents. Regarding maintenance costs, they have become an issue of great concern to many operators in the last years. Maintaining the facilities in good condition ensures the proper performance of these infrastructures and reduces the risk of failures. It should be known that equipment breakdowns imply an increase in operating costs, with a high risk of generating an environmental damage due to the m…
Designing for Networked Community Resilience
2016
Abstract Communities have been described to be at the heart of the preparedness for and the response to disasters. The increasing connectedness has made communities more vulnerable for their dependence on a complex network of critical infrastructures. At the same time, this very connectedness has the potential to enable communities to self-organise, engage, and connect with other communities to improve their resilience. While the pathway to more resilience is promising and has many advocates, the response to crises and disasters, time and again reveals the challenges related to (i) ad-hoc switching from preparedness to response; (ii) ad-hoc connecting professional responders, communities, v…
The Human Right to Social Security and Its Impact on Socio-Political Action in Germany and Finland
2017
Social human rights have rarely been given attention in social work research or comparative studies on welfare states. The paper aims at filling the gap by analysing the conception of human beings inherent in human rights and in unemployment policy documents in Germany and Finland. Its focus lies on the right to social security, a central norm of the International Covenant on Economic, Social and Cultural Rights. The main question is what impact does the right to social security have on socio-political action in Germany and Finland. The results of the analysis, which was based on the objective hermeneutics, revealed a structural similarity between the conceptions of human beings in both cou…
Proximal and distal antecedents of problematic information technology use in organizations
2021
PurposeExcessive use of work-related information technology (IT) devices can lead to major performance and well-being concerns for organizations. Extant research has provided evidence of the incidence of such problematic IT use in organizations. We extend the understanding of problematic IT use by examining its individual (proximal) and organizational (distal) antecedents.Design/methodology/approachDrawing from the self-worth theory and the concept of fear of being left behind, we address proximal antecedents that lead to problematic IT use. Drawing from the concept of autonomy paradox, we address distal antecedents of problematic IT use through a positive association with the two proximal …
Development of a Taekwondo Combat Model Based on Markov Analysis
2019
The purpose of the present study was to examine male and female Olympic taekwondo competitors' movement patterns according to their tactical actions by applying a Markov processes analysis. To perform this study, 11,474 actions by male competitors and 12,980 actions by female competitors were compiled and analyzed. The results yielded 32 significant sequences among male competitors and 30 among female competitors. Male competitors demonstrated 11 sequences initiated by an attack, 11 initiated by a counterattack, and 10 initiated by a defensive action. Female competitors demonstrated nine sequences initiated by an attack, 11 initiated by a counterattack, and 10 initiated by a defensive move.…
Migration Trends in the World and in Poland versus National Security
2020
Purpose: The aim of the paper is to analyse migration trends in the world from 1990 to the present day and economic migration in Poland in the years 2015-2019. Aspects related to national security in the context of the scale of crimes committed by economic migrants residing in Poland will also be discussed. Design/Methodology/Approach: In the research implementation process, data, and sources analysis, as well as a modeling method to show extrapolation of migration trends. Findings: The methodology used allowed the authors to determine that international migration processes have permanently entered the order of functioning of countries around the world. Practical Implications: According to …
¿Cómo se define el liderazgo en la defensa europea? Un análisis fsQCA
2017
The paper addresses the issue of national leadership in the politics of European defence, in order to determine the relative value of different factors in the exercise of leadership, and the reasons why some countries are more willing than others to contribute to the development of the EU’s Common Security and Defence Policy. The article starts by discussing the main contributions of the (neo)realist and constructivist approaches to European leadership on defence. It then highlights the process of development of EU defence policy and its setbacks. Leadership factors that characterize this development process are identified and employed to construct a fsQCA analysis, which assesses the leade…
The Social Policy Index: It's Applicability in Latin American Countries
2014
Social Policy is a tool employed by states to intervene in society with an aim of reducing the effects of poverty and inequality by meeting people's basic needs. The question is how do we measure social policy? In 2006, the United Nations Organization proposed a Social Policy Index (SPI), a methodological tool to measure social policy, with the aim of understanding the current regimes of economic and social structures in each country. The SPI suggests quantifying the elements of social policy, without focusing on their results, preferring to identify how the policy and the efforts of each government are materialized in some social indexes like social spending, social security, taxes, and in…
Der Wettbewerb zwischen Parteien der Extremen Rechten und der linken Mitte
2016
Seit den fruhen 1980er Jahren gehoren Parteien, die der „Extremen“, „Radikalen“, „Populistischen“ oder „Neuen Rechten“ zugerechnet werden, zur Realitat westeuropaischer Parteiensysteme. Die Etablierung dieser neuen Parteienfamilie stellt die westeuropaischen Demokratien vor eine Vielzahl von Herausforderungen. Dabei ist der Aspekt der Konkurrenz um Stimmen von zentraler Bedeutung. Es gibt gute Grunde zu vermuten, das die Extreme Rechte auch und gerade den sozialistischen und sozialdemokratischen Parteien Europas zusehends Konkurrenz machen konnte. Die neuen Rechtsparteien haben ihre ursprunglich oft marktliberale Rhetorik abgeschwacht und umwerben die Arbeiterschaft mit protektionistischen …
Removal of algae from biological cultures: a challenge for electrocoagulation?
2014
BACKGROUND In the search for novel technologies for the treatment of urban wastewater, combined anaerobic–algae membrane bioreactors have become a very interesting choice. Recovery of algae produced in these reactors has become the key point to obtain a good economic efficiency with this technology. In this work, electrocoagulation is studied as an alternative for the coarse removal of algae from a biological culture. RESULTS Results demonstrate that the electrochemical technology is a suitable technology for this purpose allowing the removal of more than 90% of the algae without modifying significantly the pH and with an operating cost below 0.04 € m−3. The same general trends are observed…
