Working with Traditional Knowledge: Information for Botanical Fieldwork

2012

Botanical research can often involve access to traditional knowledge, as well as to botanical material held or managed by Indigenous and Local Communities (ILCs). There is a large and growing body of local, national and international laws, declarations and codes of conduct to guide best practice in this area. Researchers and students must be aware of this changing framework before collecting material and information in areas inhabited by ILCs.

Scuola: avamposto e nuova frontiera del mutamento sociale.

2001

Il saggio si propone di analizzare la funzione educativa della scuola attraverso le Riforme degli anni '90 che hanno ridefinito il profilo non solo dei curricula ma delle modalità partecipative degli alunni e dei genitori in un'ottica sistemica.

Ragion di Stato e ragioni del capitale: il lungo crepuscolo della lira nell’Eritrea britannica, 1941-1952

2021

Il capitolo analizza le politiche monetarie adottate dal Regno Unito in Eritrea durante l'occupazione militare del 1941-1952, mostrando i conflitti interni all'amministrazione britannica e l'impiego delle riforme valutarie quali strumento di governo del territorio nello spazio coloniale.

Prey community structure affects how predators select for Müllerian mimicry

2012

Müllerian mimicry describes the close resemblance between aposematic prey species; it is thought to be beneficial because sharing a warning signal decreases the mortality caused by sampling by inexperienced predators learning to avoid the signal. It has been hypothesized that selection for mimicry is strongest in multi-species prey communities where predators are more prone to misidentify the prey than in simple communities. In this study, wild great tits ( Parus major ) foraged from either simple (few prey appearances) or complex (several prey appearances) artificial prey communities where a specific model prey was always present. Owing to slower learning, the model did suffer higher mort…

Segmentation automatique et analyse de forme d'hippocampes humains dans l'étude de la maladie d'Alzheimer

2011

The aim of this thesis is to investigate the shape change in hippocampus due to the atrophy in Alzheimer’s disease (AD). To this end, specific algorithms and methodologies were developed to segment the hippocampus from structural magnetic resonance (MR) images and model variations in its shape. We use a multi-atlas based segmentation propagation approach for the segmentation of hippocampus which has been shown to obtain accurate parcellation of brain structures. We developed a supervised method to build a population specific atlas database, by propagating the parcellations from a smaller generic atlas database. Well segmented images are inspected and added to the set of atlases, such that t…

Prehatching maternal investment and offspring immunity in the pied flycatcher (Ficedula hypoleuca).

2007

Maternal investment in offspring immunity via egg quality may be an adaptive evolutionary strategy shaped by natural selection. We investigated how maternal investment in eggs can influence offspring immunity by conducting two experiments. First, we manipulated foraging performance of the mothers before egg laying by attaching a small weight to their back feathers. During the nestling period, we investigated offspring total antibody production at the age of 7 days and after antibody challenge, and conducted a partial cross-fostering design to separate the effects of the experiment and rearing-related variation on offspring immunity. In a separate experiment, partial cross-fostering with ant…

Settlement, radiocarbon dates and craft productions during Late Neolithic and Bell Beaker periods in the ‘corredor de Montesa’ (Valencia, Spain). The…

2014

[EN] In this paper we present the results related to the excavation works conducted in Late Neolithic and Bell Beaker sites of Quintaret (Montesa, Valencia) and Corcot (l’Alcúdia de Crespins, Valencia), both in the middle valley of Canyoles river. The sites, neighboring each other, offer a quite different volume of information (Quintaret: 51 structures; Corcot: 4 structures). 14C dates allow us to define the occupation of this area of the valley along the first half of the III millennium cal BC. The presence of bell beaker ceramic in archaeological record of Quintaret is limited to just one structure (Q138), where at least 7 different vessels have been identified. Other prominent point of t…

Predicting Next Dialogue Action in Emotionally Loaded Conversation

2021

This paper reports on creating a neural network model for prediction of the next action in a dialogue considering conversation history, i.e. entities, context variables and emotion indicators marking emotionally loaded user utterances. Several experiments were performed to see how the information about emotions affects the accuracy of the model. For the purposes of these experiments, a dataset containing 206 dialogs in Latvian in the transport inquiry domain was created containing both neutral and emotionally loaded utterances. To see if the proposed next dialogue action prediction model architecture is suitable for other languages, the original Latvian utterances were translated into Engli…

Quantifying residential PV feed-in power in low voltage grids based on satellite-derived irradiance data with application to power flow calculations

2016

AbstractA scheme using satellite-derived irradiance measurements to model the feed-in power of residential photovoltaic (PV) systems in a low voltage distribution grid is described. It is validated against smart meter measurements from a test site with 12 residential PV systems in the city of Ulm, Germany, during May 2013 to December 2014. The PV feed-in power is simulated in a 15-min time resolution based on irradiance data derived from Meteosat Second Generation satellite images by the physically based retrieval scheme Heliosat-4. The PV simulation is based on the nominal power and location of the PV systems as provided by the distribution system operator. Orientation angles are taken fro…
