Flash-Floods Influence Macroinvertebrate Communities Distribution in Lotic Ecosystems
2019
Abstract Stream dwelling invertebrate populations are facing an ample array of stressors including the habitat imbalance caused by important floods. In this research we used a novel way to estimate the impact of floods upon the substrate, by utilising a remote variable named “flash-flood potential” (FFP), which accounts for the site slope and the average slope of the upstream catchment. The results showed that certain groups are sensitive to the influence of the FFP whereas other are not. We propose this remote variable as a surrogate for assessing stress imposed by floods and sediment scouring for lotic macroinvertebrates.
Integrating Circularity in the Sustainability Assessment of Asphalt Mixtures
2020
Rising concerns about the impacts that the road engineering industry is imposing to the environment have redirected national road authorities to firmly re-consider the sustainability implications of their operations. Lately, though, sustainability has established a forceful correlation with the Circular Economy and its principles. The road engineering industry, therefore, is moving towards more circular approaches. However, this is occurring without the assessment of the potential impacts of such a transition. For this reason, in this study, a composite indicator, namely, Environmental Sustainability and Circularity indicator (ESCi), for investigating the potential effects that increased ci…
Desajuste de trayectorias estudiantiles : caso comparativo de la Universidad Federal de Paraíba y la Universidad de València
2021
Este artículo aborda la cuestión del ajuste académico en las trayectorias universitarias entendiéndolo en base al ritmo de renovación de los estudiantes y de idoneidad de su rendimiento académico. El objetivo planteado es calibrar el ajuste entre ambos indicadores de rendimiento, es decir, renovación e idoneidad para poder proponer una medida integral de ajuste. Proponemos una metodología para ponderar el grado de ajuste en las trayectorias universitarias a partir de los indicadores de renovación e idoneidad mediante la propuesta de un nuevo indicador que denominamos tasa de ajuste. El procedimiento de su cálculo es a través de la adaptación del habitual índice de Gini y cuenta con la carac…
Pedestrian Safety Indicators Study
2008
Pedestrian mobility can be considered an important feature in a new model of town organization, being suitable for the newly urbanized areas as well as the old quarters and the outskirts, places where streets and squares, once devised for a pedestrian based mobility, were eventually overcame by an ever increasing motorized traffic. Enhancing pedestrian mobility could bring new life and activities into the old and historic parts of the town reviving their original identities. The last decade’s increase in the recourse to private cars requires improvements in pedestrian mobility quality. This can be achieved by building new infrastructures, limiting the use of private cars, improving public t…

Physiological stress indicators in the plasma of Scyliorhinus canicula captured by botto trawling at two depths.
2022
The quantification of capture-related physiological stress is an important factor when assessing the potential for post-release survival in sharks that are incidentally captured. In the absence of these biological data and when the post-release fate is unknown, effective management plans cannot be formulated and may lead to highly susceptible shark populations being overfished. Here, we measured the levels of lactate, glucose, alanine amino transferase (ALT), aspartate amino transferase (AST), Ca2+, Na+ K+,Cl - Mg 2+ and Pi in the plasma of mature and immature lesser spotted dogfish (Scyliorhinus canicula, herein dogfish) which were incidentally captured at two depths (shallow: 50-200 m, an…
Assessing the sustainability of small wastewater treatment systems: A composite indicator approach
2014
The assessment of the sustainability of wastewater treatment (WWT) systems has gained interest in recent years. However, most previous studies have focused on environmental and/or economic dimensions ignoring social aspects. Moreover, they tend to be based on sets of indicators rather than providing a holistic assessment. To overcome this limitation, this paper proposes an innovative methodology to assess the sustainability of WWT systems based on the development of a composite indicator embracing economic, environmental and social issues. Subsequently, the global sustainability of seven WWT technologies for secondary treatment in small communities is compared. The joint application of the …
Predictors of decline in self-assessments of health among older people--a 5-year longitudinal study.
2001
Within the framework of the Evergreen project we examined how changes in several indicators of health and functioning and physical activity predicted a decline in self-assessments of health evaluated over a 5-year period in older people by two different measurements: self-rated health (SRH) and self-assessed change in health (SACH). The study group comprised all 75-year-old persons born in 1914 (N = 382) and living in Jyvaskyla, a town in central Finland. At baseline in 1989, 91.6%, and at follow-up 5 years later in 1994, 87.3% of those eligible participated in the interview and 77.2 and 71.3%, respectively, in the examinations in the study centre, focusing on different domains of health an…
Mapping Economic Activity in the European Union: Do Ownership, Industry and Location Matter?
2020
The paper proposes a new method for analysing the structure and dynamics of economic activity undertaken by locally owned and foreign-owned companies within the European Union. We employ an unsupervised learning algorithm that generates a neural network depicted on Kohonen maps and offering a clustering of companies with a different ownership (local and foreign) from various industries and countries of the European Union during 2009–2016. The research methodology, based on a self-organizing map (SOM) algorithm, belongs to a class of neural networks trained to organize data so that unknown patterns may be discovered, thus leading to results that cannot be attained by more traditional cluster…
Temporal Series Analysis on Avoidable Mortality for the Assessment of an Intervention Program in a Hospital
2017
Background: Avoidable mortality (AM) is one of the most important health indicators (HI) and represents the quality of care in a hospital.Objective: This study measured the efficacy of a training program for a hospital healthcare staff to reduce AM.Methods: This epidemiological study on community intervention analyzed time-series data on HI by semesters from 2008 to 2015. The pre-intervention phase was examined from January 2008 to December 2014; the intervention phase was investigated in the first semester of 2015; and the post-intervention phase was examined in the second semester of 2015.Results: Resindicate a series with a rising tendency until the 14th semester and a pronounced descent…
