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…

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…

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…

Analysis of the Potential of an Increase in Yeast Output Resulting from the Application of Additional Process Wastewater in the Evaporator Station

2019

This paper reports the results of an analysis of process wastewater streams in the context of an increase in yeast production. This research is based on the analysis of data from the biggest yeast factory in Europe. The research presented in this paper involves the analysis of the influence of direction of additional wastewater into the evaporator station on yeast production. In the process wastewater, nitrogen is mainly present in organic forms. The analysis reported in this paper involves the concentration of total nitrogen in wastewater streams, as it is the main parameter applied to determine the amount of wastewater that can be applied in agricultural fields. Directing additional waste…

The importance of phytoplankton production for carbon budgets in a semiarid floodplain wetland

2011

Phytoplankton production (PP) in wetlands is not measured as often as that of macrophytes. A three year-study during a period of sustained high flooding was undertaken in a central Spanish floodplain wetland (Las Tablas de Daimiel National Park) to determine net PP, its spatial heterogeneity and controlling factors, and compare it with primary production in macrophyte communities. This enabled us to estimate carbon budgets for each community. All PP variables showed high spatial and temporal variability among sites, resulting in low coherence even when flooding connected all sites. Net PP corresponded to 25- 36% of submerged plant production and 3-10% of helophyte production. Net PP was con…

L'économie matérielle de la France (1830-2015). L'histoire d'un parasite ?

2018

This article explores the long-term dynamics of material use in France over a period of 185 years. It is based on material flow accounts that are perfectly consistent with the standards of Material Flows Analysis at the national economic scale. This work - which covers domestic extraction, imports and exports - is the first long-term study of material flows for France, with annual and national data for most of the period. Our database allows us to study the evolution of French metabolism during the industrialization of the country, together with the increasing dependence on abiotic materials. We highlight a singular metabolic trajectory: that of a state that benefits from successive world-s…

L'organisation de l'université française à la lumière de ses processus de certification

1984

International audience; L'assimilation de l'école à la firme multiproduit autonomie soulève de nombreuses difficultés contextuelles. Malgré tout, l'utilisation au cas de l'établissement scolaire des outils classiques de la théorie économique de la production est susceptible de rendre compte des conséquences de ses pratiques éducatives sur un mode de fonctionnement. En faisant référence à ce cadre d'analyse, le propos de l'auteur est de révéler ici l'organisation actuelle de l'université française en examinant le rôle des divers acteurs dans le processus de production de diplômés et de vérifier, en définitive, l'existence d'un assortiment entre les établissements et leurs publics étudiants, …
