The public and private use of space in Magdalenian societies: Evidence from Oelknitz 3, LOP (Thuringia, Germany)
2015
Abstract The site of Oelknitz (Thuringia, Germany) is among the largest and in terms of spatial organisation most complex Magdalenian open air sites known to date, rich in evident structures. The current paper reports evidence from the youngest, latest phase of occupation at Oelknitz Structure 3. It is demonstrated that this structure represents a dwelling construction characterised by different spatially distinct activity zones. Several hypotheses can be drawn from this evidence in order to understand basic principles on Magdalenians’ settlement behaviour and their social cohesion.
Progetto della chiesa di San Giacomo Apostolo a Ferrara
2012
Il progetto di Andrea Sciascia, per il complesso parrocchiale di San Giacomo Apostolo in Ferrara, terzo classificato nell’ultima edizione (sesta) dei concorsi promossi dalla CEI, interviene in un’area periferica della città, interessata da profonde trasformazioni e dall’inserimento di elementi infrastrutturali viari. La superficie di circa un ettaro, dove è presente l’originario e minuto complesso parrocchiale di San Giacomo a Ferrara, è coinvolta in profonde trasformazioni urbane fra le quali spicca un’ampia rotatoria. La perentorietà del rondeau si confronta, nella proposta di progetto, con due figure dalla geometria nitida: un rettangolo tendente al quadrato, la chiesa, e una figura allu…
Kilpailu vaikuttaa nieriän ravintoon
2013
Lapin nieriäkannat ovat monin paikoin taantuneet uusien kalalajien levittäytymisen seurauksena. Tuore väitöskirjatutkimus osoittaa, että nieriä voi vaihtaa ravintoaan ja elinpaikkaansa vähentääkseen kilpailua muiden kalalajien kanssa. nonPeerReviewed
Territorialization in Political Discourse: A Pragma-Linguistic Study of Jerzy Buzek’s Inaugural Speeches
2011
The purpose of this study is to review some discursive strategies used to (de)territorialize the European public sphere by the newly elected President of the European Parliament Jerzy Buzek. A corpus of his inaugural speeches (over 7,000 words) is examined in order to identify salient pragma-linguistic devices, such as for example high-frequency references, linguistic markers of identities, values and interests, as well as metaphors and argumentative schemata. These are presumed to have been used by Buzek to territorialize the presidential office: to position himself as its leader, to establish his credibility, to become its agenda-setter. Additionally, the analysis focuses on the way Buzek…
A spiking network for body size learning inspired by the fruit fly
2013
The concept of peripersonal space is an interesting research topics for psychologists, neurobiologists and for robotic applications. A living being can learn the representation of its own body to take the correct behavioral decision when interacting with the world. To transfer these important learning mechanisms on bio-robots, simple and efficient solutions can be found in the insect world. In this paper a neural-based model for body-size learning is proposed taking into account the results obtained in experiments with fruit flies. Simulations and experimental results on a roving platform are reported and compared with the biological counterpart.
Effects of gender inequality and wealth inequality on within-sex mating competition under hypergyny
2022
Resources are often central to the formation and persistence of human consortships, and to the evolutionary fitness consequences of those consortships. As a result, the distribution of resources within a society should influence the number and quality of mating opportunities an individual of given status/wealth experiences. In particular, in a wide variety of societies, both contemporary and historic, women have been shown to prefer mates of higher rather than lower status and wealth, a pattern known as ‘hypergyny’. Such status-dependent within-sex competition is influenced not only by the preferences individuals express but also by the distribution of resources within and between sexes. Em…
Crowdsourced analysis of fungal growth and branching on microfluidic platforms
2021
Fungal hyphal growth and branching are essential traits that allow fungi to spread and proliferate in many environments. This sustained growth is essential for a myriad of applications in health, agriculture, and industry. However, comparisons between different fungi are difficult in the absence of standardized metrics. Here, we used a microfluidic device featuring four different maze patterns to compare the growth velocity and branching frequency of fourteen filamentous fungi. These measurements result from the collective work of several labs in the form of a competition named the “Fungus Olympics.” The competing fungi included five ascomycete species (ten strains total), two basidiomycete…
Internal Simulation of an Agent’s Intentions
2013
We present the Associative Self-Organizing Map (A-SOM) and propose that it could be used to predict an agent’s intentions by internally simulating the behaviour likely to follow initial movements. The A-SOM is a neural network that develops a representation of its input space without supervision, while simultaneously learning to associate its activity with an arbitrary number of additional (possibly delayed) inputs. We argue that the A-SOM would be suitable for the prediction of the likely continuation of the perceived behaviour of an agent by learning to associate activity patterns over time, and thus a way to read its intentions.
Densities of Atlantic salmon (Salmo salar L.) fry in relation to physical habitat, spawning redd distribution and parr abundance in a small subarctic…
2014
Two small-scale surveys were conducted in a small river to examine the effects of physical habitat characteristics, spatial spawning redd distribution and abundance of older juveniles on the Atlantic salmon (Salmo salar L.) fry (age 0+) distribution 1) shortly after the emergence and 2) after the assumed main dispersal period of fry. The effect of physical habitat variables (water depth, water velocity and substratum size), spatial spawning redd distribution and densities of older juveniles were examined using multiple linear regressions. Identical models were fitted with generalized habitat suitability indices to test their applicability to predict the variation in fry densities. Clear pat…
Analysis of the impact of intermittent distribution by modelling the network-filling process
2010
In many countries, users acquire private tanks to reduce their vulnerability to water scarcity. In such conditions, water managers often apply intermittent distribution in order to reduce the water volumes supplied to the users. This practice modifies the hydraulic behaviour of the network and determines competition among users that need to collect enough water resource for their uses. Intermittent distribution is thus responsible for the inequality that can occur among users: those located in advantaged positions of the network are able to obtain water resources soon after the service period begins, while others have to wait much longer, after the network is full. This paper analyses the i…
