Human Dietary Intake of Organochlorines from Baltic Herring: Implications of Individual Fish Variability and Fisheries Management
2007
This study examines the extent to which Finnish human dietary intake of organochlorines (PCDD/Fs and PCBs) originating from Northern Baltic herring can be influenced by fisheries management. This was investigated by estimation of human intake using versatile modeling tools (e.g., a herring population model and a bioenergetics model). We used a probabilistic approach to account for the variation in human intake of organochlorines originating from the variation among herring individuals. Our estimates were compared with present precautionary limits and recommendation for use. The results show that present consumption levels and frequencies of herring give a high probability of exceeding recom…
Dasymetric distribution of votes in a dense city
2017
[EN] A large proportion of electoral analyses using geography are performed on a small area basis, such as polling units. Unfortunately, polling units are frequently redrawn, provoking breaks in their data series. Previous electoral results play a key role in many analyses. They are used by political party workers and journalists to present quick assessments of outcomes, by political scientists and electoral geographers to perform detailed scrutinizes and by pollsters and forecasters to anticipate electoral results. In this paper, we study to what extent more complex geographical approaches (based on a proper location of electors on the territory using dasymetric techniques) are of value in…
Micro-investment perspective and the potential of the universal basic income
2018
In this article, we explore the prospects of Basic Income (BI) as a development policy tool. Our approach is to analyse the BI as a tool for promoting micro-investments and as a general development policy instrument, thus deliberately departing from the perception of cash transfers as targeted poverty reduction tools. As experiences in testing BI systems in developing country contexts are limited to local and regional experiments in Namibia and India (Haarmann et al., 2009; Haarmann & Haarmann, 2012; Davala et al., 2015), conclusive assessments about the impacts of the BI cannot be drawn. Therefore, we aim to estimate potential impacts of the BI by synthesising existing knowledge. This esti…
Aplicación del Estimador de Parámetros de Segmentación por Media-desplazada (EPSM) a las imágenes de satélite de muy alta resolución espacial: Tetuán…
2015
<p>La segmentación de imágenes constituye un paso crucial en el Análisis de Imágenes Basado en Objetos (AIBO). Combinando distintos valores de los parámetros de entrada de los algoritmos de segmentación se obtienen diferentes resultados. En general, los parámetros óptimos seleccionados se determinan mediante interpretación visual; por lo tanto, la definición de las combinaciones óptimas es una tarea considerablemente difícil. En la presente investigación, se propone una herramienta analítica que denominamos Estimador de Parámetros de Segmentación por Media-desplazada (EPSM) aplicada a la selección automatizada de los valores de los parámetros de segmentación en las imágenes de satélit…
Power Grid Integration and Use-Case Study of Acid-Base Flow Battery Technology
2021
There are many different types of energy storage systems (ESS) available and the functionality that they can provide is extensive. However, each of these solutions come with their own set of drawbacks. The acid-base flow battery (ABFB) technology aims to provide a route to a cheap, clean and safe ESS by means of providing a new kind of energy storage technology based on reversible dissociation of water via bipolar electrodialysis. First, the main characteristics of the ABFB technology are described briefly to highlight its main advantages and drawbacks and define the most-competitive use-case scenarios in which the technology could be applied, as well as analyze the particular characteristi…
Different scenarios of electric mobility: Current situation and possible future developments of fuel cell vehicles in Italy
2020
The diffusion of electric vehicles in Italy has started but some complications weight its spread. At present, hybrid technology is the most followed by users, due particularly to socioeconomic factors such as cost of investment and range anxiety. After a deep discussion of the Italian scenario, the aim of the paper is to recognize whether fuel cell technology may be an enabling solution to overcome pollution problems and respect for the environment. The opportunity to use fuel cells to store electric energy is quite fascinating&mdash
La investigación sobre manuales escolares de Geografía españoles: Análisis bibliométrico (1980-2019)
2020
espanolEl objetivo de esta investigacion es llevar a cabo un analisis bibliometrico sobre los trabajos que analizan los libros de texto de Geografia espanoles (1980-2019) atendiendo a: 1) Tendencia de los trabajos publicados; 2) Grado de internacionalizacion; 3) Tipo de contribucion; y 4) Principales tematicas de estudio y etapas educativas. Los principales resultados indican que la tendencia de los trabajos publicados ha experimentado un interes notable en la ultima decada, especialmente los relacionados con el Paisaje y Climatologia. En cuanto al tipo de contribucion, los articulos son los principales (51%) y, respecto al grado de internacionalizacion, los resultados ponen de manifiesto u…
Sharing-collaborative economy in tourism: A bibliometric analysis and perspectives for the post-pandemic era
2021
Sharing economy research has risen exponentially during the last 4 years. Although several theoretical revisions on this topic have been developed, a conceptual analysis based on bibliometric techniques and science mapping tools is lacking. Within this framework, this article has two aims: (i) to carry on a performance analysis to identify the outstanding themes and (ii) to visually present the scientific structure by topics of research in sharing-collaborative economy as well as its evolution to identify future directions. The resources in the Web of Science Citation Index were used. Intelligent techniques and, more specifically, the SciMAT tool (based on co-word analysis and h-index anal…
Clusters and Industrial Districts: Where is the Literature Going? Identifying Emerging Sub-Fields of Research
2015
[EN] The industrial district and cluster literature has generated an extraordinary quantity of articles, debates and topics for discussion, and encompasses one of the most vibrant lines of research in the field of economics, geography, management and related disciplines. The literature, however, is fairly fragmented. In this paper, “bibliometric” methods are used to analyse the cluster literature published between 1957 and 2014 in order to explore “prospective” research priorities through the method of “bibliographic coupling”. Beyond focusing on foundational works in the past, this approach shifts the focus away from the practice of analysing co-citations and seminal contributions to one o…
A discursive analysis of oppositional interpretations of the agro-food system: A case study of Latvia
2015
Abstract This article critically reflects on the literature that addresses the complexity of food systems, which is often caught in application of simplistic binary oppositions of local vs. global, short vs. long, sustainable vs. intensive, etc. It then goes on to show, through a case study analysis of food-system discourses in Latvia how the binary oppositions surrounding with food systems, are actually mobilised in a specific national context. Agro-food systems are often explained through binary opposing knowledge systems that, depending on the theoretical affiliation of the author, might be called frames, narratives or discourses. These powerful instruments are used to explain, and often…
