The MIMOSE Approach to Support Sustainable Forest Management Planning at Regional Scale in Mediterranean Contexts

2017

In recent decades, Mediterranean landscapes have been affected by human-induced drivers, such as land use and climate change. Forest ecosystems and landscapes have been particularly affected in mountainous regions due to limited management and stewardship, especially in remote areas. Therefore, there is a need to set up new strategies to enhance ecosystem services in forested areas which, in turn, will benefit local communities and economies. In this study, we implemented a new approach—Multiscale Mapping of Ecosystem Services (MIMOSE)—to assess ecosystem services in Mediterranean forests located in a mountainous region of Italy. We spatially assessed timber provision and carbon sequestrati…

Data from the study: Strong temporal dynamics of ecosystem services through succession

2021

We used a nation-wide forest dataset from the Swedish National Forest Inventory (NFI) and the Survey of Forest Soils and Vegetation, covering an area of 400,000 km2 of production forests. The inventory uses a regular sampling grid with a randomly selected starting point covering the whole country, with each tract being surveyed once every 5 years. The tracts, which are rectangular in shape and are of different dimensions in different parts of the country, consists of 8 (in the north) to 4 (in the south) circular sample plots. The circular plots have different radii (5-20 meters) to ensure that the variables recorded characterize the ongoing forest dynamics and management. We used only plots…

Sustainable Supercapacitors Based on Polypyrrole-Doped Activated Biochar from Wood Waste Electrodes

2023

The synthesis of high-performance carbon-based materials from biomass residues for electrodes has been considered a challenge to achieve in supercapacitor-based production. In this work, activated biochar has been prepared as the active electrode material for supercapacitors (SCs), and an effective method has been explored to boost its capacitive performance by employing polypyrrole (PPy) as a biochar dopant. The results for physicochemical characterization data have demonstrated that PPy doping affects the biochar morphology, specific surface area, pore structure, and incorporation of surface functionalities on modified biochar. Biochar-PPy exhibited a surface area of 87 m2 g−1, while pris…

Professional social media-enabled productivity : a five-wave longitudinal study on the role of professional social media invasion, work engagement an…

2022

PurposeSocial media platforms are increasingly used at work to facilitate work-related activities and can either challenge or make people feel more productive at jobs. This study drew from technostress and employee well-being literature and analyzed longitudinal effects of professional social media (PSM) invasion, work engagement and work exhaustion on PSM-enabled productivity.Design/methodology/approachNationally representative five-wave survey data of Finnish employees were analyzed with hybrid multilevel linear regression analysis. Outcome measure was PSM-enabled productivity and the predictors included PSM invasion, work exhaustion and work engagement. Age, gender, education, occupation…

The Dark Triad, goal achievement and work engagement as predictors of counterproductive work behaviors among IT employees

2020

BackgroundThe main purpose of this article is to analyze mechanisms associated with counterproductive work behaviors. This entails ac-tions directed against the employer’s interest such as theft, slowing the work down, and avoiding professional responsibilities. This paper analyzes Dark Triad traits of psychopathy, Machiavellianism and narcissism, achievement motivation and work en-gagement as counterproductive work behavior predictors.Participants and procedureThe study included 115 people, 92 men and 23 women, who were employees of technology departments. The average age of respondents is 27.41 (Me = 26). Participants were surveyed using the online questionnaire method.ResultsStatistical …

La organización del trabajo por proyectos: La fábrica de la precariedad laboral

2019

The project-based organization, considered as a radical reorganization of work around one or more simultaneous projects, is nowadays widespread in large companies and public administrations. According to the managerial way of thinking, this system would be virtuous: by giving more autonomy to the employees in the act of production and by developing their skills through mobility and interdisciplinarity of work teams, it would be able to arouse their full commitment. This study confirms in some way how this opinion has been imposed, but at the expense of precarious working conditions, increasing the dedication of employees and silencing any form of criticism. The research is based on a review…

Compression and load balancing for efficient sparse matrix-vector product on multicore processors and graphics processing units

2021

We contribute to the optimization of the sparse matrix-vector product by introducing a variant of the coordinate sparse matrix format that balances the workload distribution and compresses both the indexing arrays and the numerical information. Our approach is multi-platform, in the sense that the realizations for (general-purpose) multicore processors as well as graphics accelerators (GPUs) are built upon common principles, but differ in the implementation details, which are adapted to avoid thread divergence in the GPU case or maximize compression element-wise (i.e., for each matrix entry) for multicore architectures. Our evaluation on the two last generations of NVIDIA GPUs as well as In…
