NEIGHBORHOOD EFFECTS IN SPATIAL HOUSING VALUE MODELS. THE CASE OF THE METROPOLITAN AREA OF PARIS (1999)
2009
In hedonic housing models, the spatial dimension of housing values are traditionally processed by the impact of neighborhood variables and accessibility variables. In this paper we show that spatial effects might remain once neighborhood effects and accessibility have been controlled for. We notably stress on three sides of neighborhood effects: social capital, social status and social externalities and consider the accessibility to the primary economic center as describing the urban spatial trend. Using spatial econometrics specifications of the hedonic equation, we estimate whether spatial effects impact the housing values. Our empirical case concerns the Metropolitan Area (MA) of Paris i…
Dominància i ocupació de l'espai en grups de primats no-humans: un model basat en conducta adaptativa
2007
L'estructura jeràrquica és una de les característiques fonamentals de les societats de primats, que condiciona en gran mesura el comportament dels individus que conviuen al grup. Quines lleis regeixen la formació i l'estructura d'aquestes jerarquies? Per què en determinats grups els subjectes més dominants se situen al centre del grup i en uns altres de la mateixa espècie no? En el camp de la conducta animal s'han proposat múltiples hipòtesis, però no n'hi ha cap que siga totalment satisfactòria, ja que a causa de les múltiples variables que hi infl ueixen, és difícil desplegar una teoria que explique tota la complexitat que s'observa empíricament. La nostra proposta d'estudi es basa en l'e…
The Evolution of Territorial Occupation:
2012
International audience; The analysis of territorial changes over time raises many methodological questions. Despite a very frequent use of spatial analysis methods, few works underline their methodological shortcomings. This paper considers a comparison and discussion of exploratory statistical methods (notably Ripley's K function and its derivatives). It is worth noting three parameters in archaeological spatial analysis: scale, quality and quantity of input data. Archaeological data are intrinsically heterogeneous. Therefore, our approach proposes a multiscalar process integrating heterogeneous data. We describe a range of methods for the description and analysis of heterogeneous spatial …
Representation of Autonomous Automata
2001
An autonomous automaton is a finite automaton with output in which the input alphabet has cardinality one when special reduced. We define the transition from automata to semigroups via a representation successful if given two incomparable automata (neither simulate the other), the semigroups representing the automata are distinct. We show that representation by the transition semigroup is not successful. We then consider a representation of automata by semigroups of partial transformations. We show that in general transition from automata to semigroups by this representation is not successful either. In fact, the only successful transition presented is the transiton to this semigroup of par…
CHILDHOOD ADVERSITIES AND HOME ATMOSPHERE AS DETERMINANTS OF DISABILITY AND UNEMPLOYMENT PENSION
2017
Childhood adversities have been linked with adverse life events, but less is known about the long-term effects of childhood home atmosphere in terms of work career. We investigated whether childhood adversities and home atmosphere were associated with disability or unemployment pension. In the Helsinki Birth Cohort Study (born 1934–44), 2001 cohort members had data available on 9 childhood home atmosphere items e.g. whether it was supportive or warm (sum score 0–36, higher score indicating more favorable atmosphere), and 9 childhood adversities e.g. unemployment, parent’s long-term illness or divorce (sum score 0–9, coded into no; one; and two or more) assessed in 2001–04. Of those, 1528 ha…
OPTIMIZING STOCHASTIC SUSCEPTIBILITY MODELLING FOR DEBRIS FLOW LANDSLIDES: MODEL EXPORTATION, STATISTICAL TECHNIQUES COMPARISON AND USE OF REMOTE SEN…
Il presente lavoro di ricerca è stato sviluppato al fine di approfondire approcci metodologici nell'ambito della sucscettibilità da frana. In particolare, il tema centrale della ricerca è rappresentato dal tema specifico dell'esportazione spaziale di modelli di suscettibilità nell'area mediterranea. All'interno del topic specifico dell'esportazione di modelli predittivi spaziali sono state approfondite tematiche relative all'utilizzo di differenti algoritmi o di differenti sorgenti, derivate da DEM o da coperture satellitari. The present work has been developed in order to enhance current methodological approaches within the big picture of the landslide susceptibility. In particular, the ce…
Análisis geodemográfico y planificación territorial en España
2002
This article studies the current role of geodemographic analysis in Spanish spatial planning; its importance, gaps and problems. This is done both from a theoretical and planning perspectives. The theoretical perspective studies the references to the population in the legal norm of the several forms of planning, and in particular in the very recent Autonomous Regions' laws. The planning perspective refers to the specific spatial plans that have been aproved. The article identifies three types of spatial planning: urban planning, town and country planning and environmental planning. Therefore, excluding the sectorial planning with spatial incidence.
Apport de la topographie par LiDAR aéroporté à la caractérisation volumique et spatiale d’amas de déchets sidérurgiques. L’exemple des ateliers de Mo…
2022
Parmi les grands districts de production de fer brut connus, la Puisaye (Bourgogne du nord – Yonne et Nièvre) figure parmi les plus importants à l’échelle métropolitaine, si ce n’est à l’échelle européenne. Plus de 2500 amas de déchets, marquant l’emplacement d’ateliers de réduction du minerai de fer, sont ainsi connus en prospections (Piétak et al. 2012). Les résultats des travaux engagés depuis 2017 dans le cadre d’un Projet Collectif de Recherche, financé par la DRAC Bourgogne-Franche-Comté et le CNRS, ont permis de révéler la continuité de ces activités de production du fer depuis le premier âge du fer jusqu’au second Moyen âge. Pour la période antique, ces amas de déchets se caractéris…
Tulkinnallinen horjuvuus ja affektit
2013
Ambiguous Meanings and Affects – Death in Monika Fagerholm’s The American Girl and The Glitter Scene The article focuses on the deaths that take place in Monika Fagerholm’s novels The American Girl (2005) and The Glitter Scene (2009). The viewpoint to the novels is that of affects. The theore¬tical framework derives from the French philosopher Gilles Deleuze (1925–1995) who is one of the best-known 20th century philosophers of affect. Firstly, the article discusses the ways in which the deaths affect the characters of the novels. Attention is paid especially to the central character called Doris Flinkenberg. She is strongly affected by the deaths that have taken place in the District where …
