Database Species-Area Relationships in Palaearctic Grasslands
2012
The Database Species-Area Relationships in Palaearctic Grasslands (GIVD ID EU-00-003) is an initiative of the European Dry Grassland Group (EDGG) and primarily functions as repository for all data sampled during the EDGG Research Expeditions. During these expeditions two types of highly standardised sampling of dry grassland vegetation in the Palaearctic realm are carried out: (i) nested-plot sampling on squares of 0.0001, 0.001, 0.01, 0.1, 1, 10, and 100 m2; (ii) additional normal releves of 10-m2 plots. For all plot sizes, the terricolous vascular plants, bryophytes, and lichens are recorded that are superficially present (shoot presence). Additionally, for all 10-m2 plots species cover i…
Advancing Design Science Research with Solution-based Probing
2019
We propose solution-based probing as an extension of action design research. The core idea is that researchers bring a prototype solution (probe) into one or more fields and explore to synthesize robust and generalizable design knowledge, along with knowledge of the phenomena and correlations we discover. We believe proposing solutions creates opportunities for researchers to innovate and to document the impact. In addition, solutions can be effective probes for advancing theory, in terms of design theories and in creating exploratory foundations for behavioral and causal theory. We illustrate solution-based probing with four exemplar studies in the areas governance of municipalities, polic…
Development of microfluidics for sorting of carbon nanotubes
2018
Sorting of carbon nanotubes by their chirality is the current bottleneck in the way to their broad employment based on their exceptional electronic and optical properties. Despite the extensive effort, there is no known method, which would result in really pure chirality ensembles. Previously reported sorting protocols result in enrichment rather than in sorting, alter electronic structure, and suffer from low yield. This is mostly due to the statistical approach, where the nanotubes with mixed chiralities are treated as a set. In this thesis, we propose a new sorting technique based on nanotube-by-nanotube compartmelization, characterization, and sorting in a continuously running droplet-b…
Sport clubs' health promotion activities for the surrounging communities : a comparative case study of Columbus Blue Jackets, HJK and Sotkamon Jymy
2014
ABSTRACT The level of physical activity continues to decrease globally. Therefore it is important to explore new ways of promoting physical activity and healthy life style. Sport clubs are an excellent setting for physical activity and health related programs targeted for the surrounding community due to their visibility, popularity and image. They offer also companies a possibility to conduct their health related corporate social responsibility activities by supporting and cooperating with the club. Despite its importance there are not many studies related to the role of sport clubs as health promoters. The aim of this research is to explore what kind of health promotion activities sport c…
Inquiry-Based Laboratory e formazione dei futuri docenti di sostegno. Apprendere per competenze nel laboratorio di “Didattica speciale: codici del li…
2022
L’Unione Europea ha più volte sottolineato l’urgenza di un rinnovamento nell’educazione e sollecitato gli Stati membri ad intervenire con iniziative atte a migliorare i sistemi di formazione degli insegnanti (Pascucci, 2014). In tale contesto gli Atenei, in accordo ai decreti ministeriali, predispongono i relativi percorsi formativi, diversificati per gradi di istruzione e introducendo l’obbligatorietà di frequenza dei laboratori. Il termine stesso laboratorio rimanda al concetto di “lavoro attivo”, un luogo dove è possibile mantenere e legittimare il divenire della professionalizzazione docente. Il laboratorio, dunque, promuove nello studente un apprendimento significativo ovvero in grado …
EdenMed: innovazione sostenibile. Il modello Inquiry based Learning in educazione
2022
Il tema della sostenibilità è oggi al centro di un dibattito che si va progressivamente articolando e arricchendo, mettendone in luce la complessità e sottolineando al contempo la necessità di un approccio olistico ed ecosistemico (Bhattacharjee, Debnath; Hinzen, Schmitt, 2016; Leicht, Heiss, Byun, 2018; Lundvall, Fröberg, 2022; Malavasi, 2020; Stein et alii, 2022;). L’Agenda 2030, firmata da tutti i Paesi dell’ONU nel 2015, impegna governi, comunità educanti e singoli verso un nuovo modello di sviluppo sostenibile, capace di ristabilire un equilibrio tra i diversi sistemi prima che si arrivi ad un punto di non ritorno. La sostenibilità non è una questione puramente ambientale. Con l’agenda…
Argument graph as a tool for promoting collaborative online reading
2013
This study explored how the construction of an argument graph promotes students' collaborative online reading compared to note-taking. Upper secondary school students (n = 76) worked in pairs. The pairs were asked to search for and read source material on the Web for a joint essay and either construct an argument graph or take notes during online reading. The data consist of transcription protocols of student pairs' discussions and joint essays. The study indicated that argument graphs may be useful tools when teachers want students to pay attention to the argumentative content of online sources and to consider relations between arguments. Additionally, with argument graphs, teachers can su…
Models and methods for space and space-time interactions in complex point processes with applications on earthquakes
Continuum: A spatiotemporal data model to represent and qualify filiation relationships
2013
International audience; This work introduces an ontology-based spatio-temporal data model to represent entities evolving in space and time. A dynamic phenomenon generates a complex relationship network between the entities involved in the process. At the abstract level, the relationships can be identity or topological filiations. The existence of an identity filiation depends on whether the object changes its identity or not. On the other hand, topological filiations are based exclusively on the spatial component, like in the case of growth, reduction, merging or splitting. When combining identity and topological filiations, six filiation relationships are obtained, forming a second abstrac…
Probabilistic and preferential sampling approaches offer integrated perspectives of Italian forest diversity
2023
Aim: Assessing the performances of different sampling approaches for documenting community diversity may help to identify optimal sampling efforts and strategies, and to enhance conservation and monitoring planning. Here, we used two data sets based on probabilistic and preferential sampling schemes of Italian forest vegetation to analyze the multifaceted performances of the two approaches across three major forest types at a large scale. Location: Italy. Methods: We pooled 804 probabilistic and 16,259 preferential forest plots as samples of vascular plant diversity across the country. We balanced the two data sets in terms of sizes, plot size, geographical position, and vegetation types. F…
