Data from: Optimizing management to enhance multifunctionality in a boreal forest landscape

2016

1. The boreal biome, representing approximately one third of remaining global forests, provides a number of crucial ecosystem services. A particular challenge in forest ecosystems is to reconcile demand for increased timber production with provisioning of other ecosystem services and biodiversity. However, there is still little knowledge about how forest management could help solve this challenge. Hence, studies that investigate how to manage forests to reduce trade-offs between ecosystem services and biodiversity are urgently needed to help forest owners and policy-makers take informed decisions. 2. We applied seven alternative forest management regimes using a forest growth simulator in a…

Safety evaluation of turbo roundabout with and without internal traffic separations considering autonomous vehicles operation

The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been mixed with conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs compared to roundabouts without curbs. The paper shall also lead to describe the methodological path followed to build VISSIM models of turboroundabout with and without raised curbs, to calibrate the simulation mode…

Estimating traffic operations at multi-lane roundabouts: A case study

2014

This paper addresses traffic modeling issues at urban multi-lane roundabouts where, despite circulating vehicles have priority, negotiation of the right-of-way can occur between antagonist traffic flows, as a result of minor drivers’ failing to obey the nominal operating rule (stop or yield control). Existing models for the estimation of operational performances have the shortcoming of not representing the interdependencies between entering and circulating vehicles at multi-lane roundabouts. An analytical capacity model derived from field observations was developed for this kind of intersections in a previous study. The complexity of the model lies in the difficulty of observing the behavio…

LCA of Different Construction Choices for a Double-Track Railway Line for Sustainability Evaluations

2023

The international commitment to achieve carbon neutrality in the next few decades has oriented human activities towards the preservation of natural and non-renewable resources. In this context, a great research effort has been devoted to the search for sustainable solutions for the infrastructure construction sector, based on a thorough assessment of the environmental impact (EI). In this regards, Life Cycle Assessment (LCA) is considered one of the main components of Environmental Impact Assessment (EIA) and, for a comprehensive analysis, all the costs incurred by stakeholders during the useful life of the infrastructure should also be taken into account, applying the Life Cycle Cost (LCC)…

Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation

2021

The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …

Modello di capacità e valutazione delle prestazioni per le rotatorie a turbina.

2008

L’evoluzione più recente delle intersezioni a rotatoria si è indirizzata verso schemi cosiddetti a turbina (turborotatorie) con l’obiettivo di garantire condizioni di sicurezza più elevate rispetto agli schemi tradizionali. I pochi esempi di realizzazione delle rotatorie a turbina non hanno tuttavia finora consentito di sviluppare metodi di analisi delle condizioni operative e modelli di capacità che possano vantare una validazione attraverso osservazioni di campo. In ogni caso, l’approccio teorico allo studio funzionale delle turborotatorie presenta aspetti decisamente più complessi di quelli delle rotatorie convenzionali sia a causa delle traiettorie dei flussi in ingresso (costretti ad i…

Agency of labour in a flexible pan-European labour market : a qualitative study of migrant practices and trade union strategies in the Netherlands

2015

Regulatory frameworks on intra-EU mobility and flexible cross-border employment relations have stimulated competition on labour costs by recruiting migrants via cheaper labour market regimes. While it allows firms to remunerate migrants under different terms and conditions, blurring regulatory boundaries also generates opportunities for non-compliance, resulting in violations of migrant labour rights across Europe. Against this background, this thesis explores the agency of labour, more specifically of temporary migrant workers and unions, and the ways they cope with and respond to the competitive dynamics of the pan- European labour market. This study draws on 90 qualitative interviews wit…

Investor-state dispute settlement - podstępne zagrożenie dla sprawnego działania administracji publicznej

2017

ISDS (investor-state dispute settlement, znany także jako ICS - investment court system) to umowny mechanizm rozstrzygania sporów między inwestorem a państwem. Polega on na możliwości zaskarżenia państwa przez przedsiębiorcę (inwestora) do arbitrażu wówczas, gdy państwo wydaje lub wykorzystuje przepisy ograniczające zyski przedsiębiorstwa (praktyki dyskryminujące). Arbitrami ISDS jest kilkunastu sowicie opłacanych prawników, pracujących dla wielkich kancelarii międzynarodowych, którzy niemal nigdy nie orzekają na korzyść państwa. Przedsiębiorca może żądać wysokiego odszkodowania: nie tylko zwrotu utraconych korzyści, lecz także spodziewanych zysków, których wysokości nie musi nawet drobiazg…
