Future wood demands and ecosystem services trade-offs: A policy analysis in Norway
2023
To mitigate climate change, several European countries have launched policies to promote the development of a renewable resource-based bioeconomy. These bioeconomy strategies plan to use renewable biological resources, which will increase timber and biomass demands and will potentially conflict with multiple other ecosystem services provided by forests. In addition, these forest ecosystem services (FES) are also influenced by other, different, policy strategies, causing a potential mismatch in proposed management solutions for achieving the different policy goals. We evaluated how Norwegian forests can meet the projected wood and biomass demands from the international market for achieving m…
Use of the Sperm-Class Analyser® for objective assessment of human sperm morphology
2003
The Sperm-Class Analyser was validated for assessing morphometric parameters of the head and midpiece of unwashed and washed human ejaculated spermatozoa from volunteers providing a wide range of semen quality. A higher proportion of sperm could be assessed (86% fresh semen and 75% washed sperm) if Hemacolor staining was used rather than DiffQuik (80 and 73%) or Papanicolaou (78 and 68%). Different stains employed different fixatives and the area, length, width and perimeter of the sperm head was significantly larger for washed sperm stained by Hemacolor and DiffQuik. Acrosomal area ranged from 48 to 51% of the sperm head area and this percentage was larger for washed sperm stained with Dif…
Valutazione e personalizzazione a scuola: le prove oggettive di profitto
2022
La scelta delle modalità e degli strumenti di valutazione da impiegare con i propri allievi, in base a ciò che si vuole valutare e al perché, è uno dei compiti didattici dell’insegnante, la gamma di scelta è ampia; in questo intervento ci soffermeremo su alcuni aspetti connessi alla scelta e all’impiego di un tipo di prove per la valutazione del grado di conseguimento degli obiettivi di apprendimento previsti al termine di un’attività didattica, esse sono comunemente denominate prove oggettive di profitto volendo così sottolineare l’intento di ridurre il più possibile la soggettività dell’insegnante quando valuta i suoi alunni. The choice of assessment methods and tools to be used with your…
On Constraint Handling in Surrogate-Assisted Evolutionary Many-Objective Optimization
2016
Surrogate-assisted evolutionary multiobjective optimization algorithms are often used to solve computationally expensive problems. But their efficacy on handling constrained optimization problems having more than three objectives has not been widely studied. Particularly the issue of how feasible and infeasible solutions are handled in generating a data set for training a surrogate has not received much attention. In this paper, we use a recently proposed Kriging-assisted evolutionary algorithm for many-objective optimization and investigate the effect of infeasible solutions on the performance of the surrogates. We assume that constraint functions are computationally inexpensive and consid…
Oral proficiency in second and third foreign languages in the Danish education system
2019
In this paper, we analyze how oral proficiency is understood in the Danish education system in the three biggest second/third foreign languages taught in the country: French, Spanish and German. We adopt a comparative perspective and analyze how orality is addressed in these language subjects at primary school, secondary school and university levels. We compare the three languages to find similarities and differences, focusing on learning objectives, pedagogical approaches and examination forms, presented in the official curricula for each of the three educational levels. We relate the Danish stance on oral proficiency to current international research in the field and to European tendencie…
A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network
2016
International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…
ISSUES ON FISCAL POLICY OBJECTIVES IN ROMANIA AFTER 2000
2010
Financial policy differs from one country to another depending on the country's economic potential, the level of economic development, natural resources, national or international conditions, methods of managing the national economy, the interests of political parties and other factors. But, we should not overlook the fact that economic and financial experience of countries can provide models to be applied in other countries. In terms of financial policy, budgetary policy and fiscal policy are the most important. This paper aims to compare the objectives of fiscal policy in Romania during the last three programs of government in the period 2001-2012 and, under the Romanian fiscal responsibi…
A multi-objective fleet routing optimization for passenger shipping among islands
2009
In the last few years the statistical analysis on maritime freight and passenger transport highlights a positive trend of demand and for the next future, given the stressing congestion characterizing the road transport, a further increase both on the deep-sea-shipping and the short-sea-shipping is predicted. Given that, the navigation companies are called to improve their own services to assure a high quality and efficient customers transport, deriving at the same time their own benefits by minimizing the operating costs. Hence, an efficient and careful routes planning activity plays a meaningful role on navigation company productivity and income. Furthermore, the fleet deployment also cons…
G-CLASS: geosynchronous radar for water cycle science – orbit selection and system design
2019
The mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on timescalesless than a day are very poorly observed from space. G-CLASS, using C-band geosynchronous radar, could transform this. Itsscience objectives address intense storms and high resolution weather prediction, and significant diurnal processes such assnow melt and soil moisture change, with societal impacts including agriculture, water resource management, flooding, andlandslides. Secondary objectives relate to ground motion observations for earthquake, volcano, and subs…
Una ricerca-intervento per costruire il giudizio sintetico globale degli alunni
2022
For the formulation of the synthetic global judgment of the primary school pupil it is proposed to use EU key competences as indicators and as descriptors of the overall educational goals of the class council which constitute the operational formulation of the fundamental objectives of the S.O.F.E.
