Living and Dead Aboveground Biomass in Mediterranean Forests: Evidence of Old-Growth Traits in a Quercus pubescens Willd. s.l. Stand

2017

For a long time, human impact has deeply simplified most of the forest ecosystems of the Mediterranean Basin. Here, forests have seldom had the chance to naturally develop a complex and multilayered structure, to host large and old trees and rich biological communities, approaching old-growth conditions. Also for this reason, limited information is currently available about Mediterranean old-growth forests, particularly with regard to deadwood. The main aim of this work is to help fill this critical knowledge gap. In Sicily (Italy), we identified a Quercus pubescens forest that seemed to show some typical old-growth features. Total living volume (360 m3 ha−1) and basal area (34 m2 ha−1) wer…

Phytosociological survey vegetation map of Sicily (Mediterranean region)

2016

ABSTRACTWe present the results of a study aimed at developing a vegetation map of Sicily (Italy) including the smaller circum-Sicilian islands, for an area of approximately 25,703 km2. The work is a synthesis of studies carried out in accordance with the survey methodology of phytosociology in the last 40 years over the whole study area. The vegetation map of Sicily was compiled in a Geographical Information Systems (GIS) environment, in order to produce a cartographic representation at a scale of 1:10,000 (reduced to a scale of 1:250,000). The physiognomic-structural characteristics of the plant landscape of Sicily are analyzed, providing a general and, at the same time, detailed overview …

Seasonal fluctuations in leaf phenolic composition under UV manipulations reflect contrasting strategies of alder and birch trees

2010

Seasonal variation in leaf phenolic composition may be important for acclimation of plants to seasonal changes in their biotic and abiotic environment. For a realistic assessment of how plants respond to solar UV-B (280-315 nm) and UV-A (315-400 nm) radiation, seasonal variation in both environment and plant responses needs to be taken into account. This also has implications for studies concerning stratospheric ozone depletion and resulting increased UV-B radiation, as other environmental variables and/or plant phenology could interact with UV radiation. To elucidate this, we established a field experiment using plastic films attenuating different parts of the solar UV spectrum. The concen…

Advanced teleoperation and control system for industrial robots based on augmented virtuality and haptic feedback

2021

[EN] There are some industrial tasks that are still mainly performed manually by human workers due to their complexity, which is the case of surface treatment operations (such as sanding, deburring, finishing, grinding, polishing, etc.) used to repair defects. This work develops an advanced teleoperation and control system for industrial robots in order to assist the human operator to perform the mentioned tasks. On the one hand, the controlled robotic system provides strength and accuracy, holding the tool, keeping the right tool orientation and guaranteeing a smooth approach to the workpiece. On the other hand, the advanced teleoperation provides security and comfort to the user when perf…

Teleoperation of industrial robot manipulators based on augmented reality

2020

[EN] This research develops a novel teleoperation for robot manipulators based on augmented reality. The proposed interface is equipped with full capabilities in order to replace the classical teach pendant of the robot for carrying out teleoperation tasks. The proposed interface is based on an augmented reality headset for projecting computer-generated graphics onto the real environment and a gamepad to interact with the computer-generated graphics and provide robot commands. In order to demonstrate the benefits of the proposed method, several usability tests were conducted using a 6R industrial robot manipulator in order to compare the proposed interface and the conventional teach pendant…

Public Policy Design for Climate Change Adaptation: A Dynamic Performance Management Approach to Enhance Resilience

2017

This chapter proposes dynamic performance management (DPM) as a suitable method to identify policies in the context of climate change adaptation. Namely, it focuses on the role it can play to support the analysis of how to enhance resilience of social and economic systems to climate change. While ‘resilience’ is a buzzword in the policymaking world, putting the concept into practice is still undeveloped. In a public administration focused on accountability, intangible outcomes of resilience represent a complication. The chapter discusses the findings and lessons from a case study applying the proposed approach. The results highlight the role of a dynamic performance approach to support stak…

The ‘Open Garden of Politics’: The impact of open primaries for candidate selection in the British Conservative Party

2016

International audience; Since 2003, hundreds of open primaries for the selection of parliamentary candidates have been held by the British Conservative Party as a means of democratising party organisation and enhancing representativeness. In the run-up to the 2015 general election, only 26 primaries could be identified. This article will apply the analytical framework provided by Hazan and Rahat to demonstrate that the relative failure of the experiment in terms of intra-party competition, participation, representation and responsiveness is counterbalanced by the benefits brought by this procedure, both as a tool of party branding at the national level and as a strategy for raising the prof…

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 …
