isotracer: An R package for the analysis of tracer addition experiments
2022
Tracer addition experiments, particularly using isotopic tracers, are becoming increasingly important in a variety of studies aiming at characterizing the flows of molecules or nutrients at different levels of biological organization, from the cellular and tissue levels, to the organismal and ecosystem levels. However, performing rigorous statistical analyses to gain reliable quantitative insights from these experiments often remains challenging. We present an approach based on Hidden Markov Models (HMM) to estimate nutrient flow parameters across a network, and its implementation in the R package isotracer. The isotracer package is capable of handling a variety of tracer study designs, inc…
Examining Open Innovation in Science (OIS): what Open Innovation can and cannot offer the science of science
2021
Scholars across disciplines increasingly hear calls for more open andcollaborative approaches to scientific research. The concept of OpenInnovation in Science (OIS) provides a framework that integratesdispersed research efforts aiming to understand the antecedents,contingencies, and consequences of applying open and collaborativeresearch practices. While the OIS framework has already been taken upby science of science scholars, its conceptual underpinnings requirefurther specification. In this essay, we critically examine the OIS conceptand bring to light two key aspects: 1) how OIS builds upon OpenInnovation (OI) research by adopting its attention to boundary-crossingknowledge flows and by…

The Circularity of MSW in Urban Landscapes: An Evaluation Method for a Sustainable System Implementation
2022
The debate on the sustainable perspective of a circular economy and MSW (Municipal Solid Waste) management is no longer focused on the resolution of an emergency and on the pure technicality of creating efficient services. New light has been shed on the operational phase, as often unresolvable technical-environmental issues during service management lead to a state of decay, affecting urban vulnerability and users’ involvement. The research aims to develop an auxiliary tool for public administrations in planning a zero-waste future whilst enhancing the urban landscape. This study considers the perspective of virtuous management of the resource flow cycle along with evaluating implementable …

A CRITICAL STUDY CONCERNING THE PREPARATION OF THE STATEMENT OF CASH FLOWS THROUGH THE INDIRECT METHOD IN ROMANIA
2012
Although not bound by law, by option, small and medium entities from Romania can prepare the statement for the modifications within their equity and / or the statement of cash flows. When companies select this option, any decision made by the consumer of accounting information is better founded, from the perspective of information sources that it uses, rather than the opposite, because the users of accounting information about a company are almost always interested by the way in which the company generates and uses cash and cash equivalents. In this paper we present the particularities implied in Romania by the preparation of the statement of cash flows using the indirect method.
Changes of total annual runoff distribution, high and low discharges in Latvian rivers
2009
Changes of total annual runoff distribution, high and low discharges in Latvian rivers The paper examines climate change impacts on the hydrological regime of nineteen different river basins in Latvia. Hydrological data series for the period of 1951-2006 were analysed for river basins of four hydrological districts: Western, Central, Northern and Eastern. Climate change has influenced the temporal and spatial distribution of total annual river runoff and high and low flows in Latvia at the turn of century. The results confirm the hypothesis that the main tendency in the run-off change is a decrease in spring floods and increase in winter. Generally, statistically insignificant long-term tre…
The aporia of the European myth. How LGBTI+ migrants are stranded in the Italian reception system
2021
Considerando l’aumento di migranti e la tipologia di accoglienza orientata ad un approccio assistenziale standardizzato e omogeneo, il presente articolo indaga gli effetti della preponderanza di un sistema di prima accoglienza, nell’identificazione ed assistenza ai richiedenti asilo SOGI (sexual orientation and gender identity). La risposta tempestiva di un apparato di accoglienza basato su un approccio di sopravvivenza a breve termine, tende a ignorare le particolari esigenze dei richiedenti asilo SOGI, e di sottovalutare il rischio di violenza dentro dei centri dalla parte degli altri ospiti. Quindi, questo saggio intende riflettere se, i migranti SOGI sono una categoria vulnerabile per s…
High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method
2018
We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a three-dimensional lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number $\mathrm{Re}=5\ifmmode\times\else\texttimes\fi{}{10}^{4}$ for this setup. Excellent agreement with energy balance equations, computational and experimental results are shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of turbulent production.
