A European Multi Lake Survey dataset of environmental variables, phytoplankton pigments and cyanotoxins
2018
Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ecosystem services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution and climate-change induced stressors, like poor transparency, increased water temperature and enhanced stratification. Consistency in data collection and analysis methods is necessary to achieve fully comparable datasets and for statistical validity, avoiding issues linked to disparate data sources. The Europea…
Effects of fish feeding by snorkellers on the density and size distribution of fishes in a Mediterranean marine protected area
2005
Although there is a great deal of evidence to show that supplementary feeding by humans in terrestrial environments causes pronounced changes in the distribution and behaviour of wild animals, at present very little is known about the potential for such effects on marine fish. This study evaluated the consequences of feeding by snorkellers on fish assemblages in the no-take area of the Ustica Island marine protected area (MPA; western Mediterranean) by (1) determining if reef fish assemblage structure is affected in space and time by tourists feeding the fish; (2) assessing the effects of feeding on the abundance of the most common fish species; and (3) assessing the effects of feeding on t…
The Impact of Human Recreational Activities in Marine Protected Areas: What Lessons Should Be Learnt in the Mediterranean Sea?
2002
. The aesthetic appeal of marine reserves and the facilities provided, together with the increased public awareness of nature, all contribute to creating massive tourism in MPAs. Human activities are being changed inside MPAs in two ways: humans as top predators are generally being removed, but in turn they could come back at great numbers as visitors. Many authors have studied the impact of visitors, and the results highlight that the consequences can be very substantial and may represent a severe threat to the overall diversity of marine communities. To date, the documented effects of human recreational activities on natural communities are restricted to assessing the consequences of tram…
The Port and its Environment
2013
In times of increasing environmental awareness, the port-city relationship has gained a new meaning since ports have been seen as the origin of both negative and positive externalities affecting the public wellbeing. While the former are the result of port expansion, the latter are the result of transforming obsolete port areas into recreational facilities. Therefore, in order to support effective policy-making, in this research is emphasized the need of measuring these environmental externalities. Considering their non-market nature, the contingent valuation method is introduced as an economic tool capable of overcoming this obstacle. Thus, the cases of two ports in Spain, namely Valencia …
The creative class: do jobs follow people or do people follow jobs?
2017
Accepted manuscript version. Published version available in Regional Studies, DOI: 10.1080/00343404.2016.1254765 Regional adjustment models are applied to explore causal interaction between two types of people distinguished by educational attainment, and two types of jobs: creative class jobs and other jobs. Data used are for labour market regions in Finland, Norway and Sweden from the 2000s. Creative class jobs follow people with high educational attainment (one way causation), but creative class jobs also follow other jobs and vice versa (circular causation). The results suggest that stimulating creative class job growth could be accomplished through attracting people with higher educatio…
Development, Current Situation and Future Prospects of the Private Sport Sector in Europe
2017
This book outlined the private sport sector of the 18 European countries by using the Statistical classification of economic activities in the European Community (NACE Rev. 2, 2008) as a basic statistical framework. According on the country chapters European sport is divided into public, voluntary and private sectors. Depending on how strongly and through what kind of historical processes these sectors have developed, European countries taking part in this project can be classified as 1) historically and traditionally strong non-profit voluntary sport sector countries, 2) former Eastern Bloc countries and 3) countries with strong commercial sport activities. Based on the statistics, sport g…
Regional Integration in Trade Theory
2021
Given widespread scepticism in trade economics about the value of RECs comprised of developing countries, the formal theory of regional economic integration is critically examined in four stylized configurations. Based on the overarching logic of trade creation and diversion, the usual diagrammatic treatment of tariff effects is critically discussed in terms of its numerous shortcomings. A single-country and REC-wise diagrammatic treatment of tariffs in the presence of increasing returns is proposed to allow quantitative assessment of the arguably most promising case for South-South RECs. Building on the literature, the cases of full and incomplete specialization within a regional group are…
Complexity in project co-creation of knowledge for innovation
2020
The European Union (EU) promotes collaboration across functions and borders in its funded innovation projects, which are seen as complex collaboration to co-create knowledge. This requires the engagement of multiple stakeholders throughout the duration of the project. To probe complexity in EU-funded innovation projects the research question is: How does complexity affect the co-creation of knowledge in innovation projects, according to project participants? The data for this study was collected from project experts in the form of short narratives, using a questionnaire based on the elements of complexity of Mitleton-Kelly (2003). The results indicate that complexity characterises the co-cr…
Análisis y resultados de un modelo de evaluación, apoyo y mejora de proyectos empresariales impulsados por jóvenes emprendedores1,2
2009
ResumenLas empresas de nueva creación juegan un papel crucial en la generación de empleo, el crecimiento económico, la innovación y la competitividad. Ello ha llevado a un número creciente de instituciones públicas a dedicar ingentes recursos al apoyo y fomento de iniciativas empresariales. Resulta por ello de especial interés analizar la eficacia de los distintos programas e identificar cuáles son las prácticas más efectivas. Este trabajo tiene como objetivo avanzar en la mejora de los sistemas de evaluación de programas de ayuda a emprendedores y mostrar cómo las mejoras introducidas pueden tener efectos sobre la calidad de los negocios creados. Para ello se analiza en profundidad el caso…
An international cohort comparison of size effects on job growth
2015
The contribution of different-sized businesses to job creation continues to attract policymakers’ attention, however, it has recently been recognized that conclusions about size were confounded with the effect of age. We probe the role of size, controlling for age, by comparing the cohorts of firms born in 1998 over their first decade of life, using variation across half a dozen northern European countries Austria, Finland, Germany, Norway, Sweden, and the UK to pin down size effects. We find that a very small proportion of the smallest firms play a crucial role in accounting for cross-country differences in job growth. A closer analysis reveals that the initial size distribution and surviv…
