The role of two non-indigenous serpulid tube worms in shaping artificial hard substrata communities: case study of a fish farm in the central Mediter…
2019
Understanding the spread and establishment of non-indigenous species (NIS) is one of the primary areas of focus in bioinvasion science and is essential for generating appropriate management strategies in aquaculture. Here we investigated the role of 2 non-indigenous serpulid tube worms (Hydroides elegans and H. dirampha) in shaping the hard substrata communities around a fish farm in the Strait of Sicily over 1 yr (June 2014-June 2015), at 3 mo intervals (September and December 2014, March and June 2015). The mean density values of serpulids were significantly different at each sampling time. The density of serpulids on submerged panels showed a peak in spring (March 2015, after 9 mo) and d…
Spectrofluorimetric study of dissolved organic matter in River Salaca (Latvia) basin waters
2012
Dissolved organic matter (DOM) in surface waters influences mineral weathering, nutrient cycling, aggregation of particulate matter and photochemical reactions in waters and aquatic communities. In this study, the effectiveness of UV and fluorescence measurements in distinguishing the origin of DOM and processes within the river basin were analyzed using the River Salaca basin as an example. The basin of River Salaca is characterized by low anthropogenic pressure, however, the water color during the last few decades has increased (an effect known as brownification). As tools to study the composition of dissolved organic substances in waters of the River Salaca and its tributaries the use of…
Invasive crayfish increase habitat connectivity: a case study in a large boreal lake
2013
Several studies have shown that distinct compartments of lake ecosystems are coupled via transportation of organic matter, nutrients and energy across habitat boundaries. Here we evaluate the potential of the invasive signal crayfish (Pacifastacus leniusculus (Dana)) to modify energy pathways in large boreal lakes. Using a stable isotope mixing model and calculation of the isotopic niches we estimated the contribution of different food sources to the diets of crayfish captured from different habitats, and from that inferred their potential to transport energy across the littoral-profundal gradient. The crayfish caught from the littoral area utilized mainly littoral food sources, whereas the…
The ECHR Condemns Prison Overcrowding in Italy: The Total Reorganization of the Institution and the Social Reintegration of the Prisoner
2017
The contribution analyses the current Italian prison system, which has been called upon on to resolve its structural problems. The Council of Europe, in fact, in 2013 condemned Italy for inhuman treatment in its prisons. The principal accusation concerns the problem of overcrowding. The country has responded with solutions such as the application of the open system, which provides cells solely for overnight stays, and dynamic monitoring, an effective system for ensuring order in the institutions. These initiatives aim to promote re-educational activities and the social re-integration of prisoners. In addition, Italian institutions have made greater use of alternatives to custodial penalties…
EU Cultural Security Law in an Educational Context
2021
Cultural security is a comprehensive notion that has gained much attention in the recent cultural heritage debates. In terms of the EU, it encapsulates cultural heritage destruction and protection in armed conflicts, post-war cultural heritage management, restitution, illicit traffic of cultural property, cultural diversity, and intercultural dialogue. The article aims to present how cultural security matters appear in the EU legal system and policy. The authors argue that cultural security is present in different policies regarding cultural property and the fight against illicit trafficking, as well as in EU external cultural relations. Digitization in the cultural sector constitutes a cha…
Carbon emissions by Ssouth american companies: driving factors for reporting decisions and emissions reduction
2018
In the last decade, companies have started to disclose information on carbon emissions. To our knowledge, this is the first paper to look into this phenomenon in South America, which is a very important geographical area regarding climate change because of the local nature and developing economies. This paper explores the relationships between some corporate variables and two important decisions: (i) whether to report carbon emissions, and (ii) the impact on the evolution of carbon emissions. Logit and linear panel data models are used to determine the driving factors for decisions (i) and (ii). Our results show that regarding the carbon reporting decision, a company&rsquo
Mayors, Using Cultural Expenditure in An Opportunistic Way Improves the Chances of Re-Election, but Do Not Do It: Revisiting Political Budget Cycles
2020
This article analyzes whether expenditure on the provision of merit goods, culture, health, education, and sports, by local governments, in medium-sized cities (between 20,000 and 100,000 inhabitants) is tied to the electoral cycle
Transformative Policies for the Social and Solidarity Economy: The New Generation of Public Policies Fostering the Social Economy in Order to Achieve…
2020
The United Nations Agenda 2030 has recognized that Social Economy (SE) entities play an important role in achieving the Sustainable Development Goals (SDG). In order to maximize the impact of the SE, governments have recently deployed new policies regarding these entities. The objective is to understand the context of policy change that has allowed these policies to emerge, their main characteristics and the critical factors in their construction and implementation. Successful policy cases in Europe and Spain have been studied. Qualitative data have been collected through key policy documents, experts, and focus groups. As a main finding, the study shows that this new model of policies exhi…
Penyagolosa Trails: From Ancestral Roads to Sustainable Ultra-Trail Race, between Spirituality, Nature, and Sports. A Case of Study
2019
[EN] The organization of an open-air sporting event involves a series of challenges. People are drawn by the desire to do sport, preferably in close contact with nature, so as to complement healthy lifestyles, and in search of air purity. Sporting organizations are increasingly searching for new locations that do not only attract athletes, but spectators and companions too. Races in natural parks provide the additional benefit of doing sport in a unique space, usually a transmitter of simplicity, pure air, and tranquillity. Organizing a mountain race in a natural park implies some issues. These are areas of great environmental richness that must be protected. Natural parks are places of ind…
Towards a sustainable leader-follower relationship: constructive dissensus, organizational virtuousness and happiness at work (haw)
2020
This paper examines how leaders and followers can interact positively under complex and bounded conditions. For this purpose, this paper conceptualizes and measures the concept of constructive dissensus. Constructive dissensus relates to a mutual understanding leading to a situation of coregulation. In addition, the relationship between constructive dissensus and happiness at work is examined on the basis of affective events theory. Furthermore, the mediating role of organizational virtuousness is assessed. Through structural equation modeling, a multilevel analysis was performed. Data from 130 bank branches and 606 employees were gathered. The results reveal a direct effect of constructive…
