Media merkitysten välittäjänä : lasten tulkintoja Risto Räppääjä -elokuvien naishahmoista
2016
Jurvanen, Sirja. 2015. Media merkitysten välittäjänä – Lasten tulkintoja Risto Räp-pääjä –elokuvien naisista. Kasvatustieteen pro gradu -tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. Tämän tutkimuksen tavoitteena on tutkia Risto Räppääjä -elokuvien lapsille välittämää naiskuvaa lasten tulkintojen kautta. Tutkielman aluksi käsittelen mediaa kasvuympäristönä sosiokulttuurisen tausta-ajattelun kautta. Sosiokulttuurisessa näkökulmassa oppiminen nähdään kokonaisvaltaisena prosessina, jossa ympäristöllä, kuten medialla on vaikutusta ihmiseen ja ihmisellä ympäristöön. Media vaikuttaa moneen seikkaan, kuten käyttäytymiseen, tunteisiin ja identiteettiin. Käsittelen lisäksi lasten aktiivi…
Unexpected vertical structure of the Saharan Air Layer and giant dust particles during AER-D
2018
The Saharan Air Layer (SAL) in the summertime eastern Atlantic is typically well mixed and 3–4 km deep, overlying the marine boundary layer (MBL). In this paper, we show experimental evidence that at times a very different structure can be observed. During the AERosol properties – Dust (AER-D) airborne campaign in August 2015, the typical structure described above was observed most of the time, and was associated with a moderate dust content yielding an aerosol optical depth (AOD) of 0.3–0.4 at 355 nm. In an intense event, however, an unprecedented vertical structure was observed close to the eastern boundary of the basin, displaying an uneven vertical distribution and a very …

Une réévaluation de l'Objectif de Scolarisation Primaire Universelle sous l'angle des acquis scolaires
2013
Cette présentation a pour objectif de proposer une analyse comparative de la qualité de l'éducation au sein des pays d'Afrique subsaharienne. Par qualité, nous entendons l'éducation non pas en termes d'allocations de moyen, mais de résultats de l'apprentissage des élèves. Il s'agit de la première analyse intégrant une trentaine de pays africains dans une optique de comparaison internationale des acquis scolaires. En fusionnant les deux évaluations existantes en Afrique subsaharienne, nous disposons d'indicateurs comparables sur les acquis des élèves pour 29 pays. Par ailleurs, étant donné que certains pays ont participé à plusieurs évaluations depuis les années 1990, il devient possible d'é…
The Monster Analogy: Why Fictional Characters are Frankenstein's Monsters
2019
The Unwritten (2009–2015), a Vertigo comics series created by Mike Carey and Peter Gross, demonstrates through metafictional storytelling that all fictional characters share important features with Victor Frankenstein’s infamous creature: they are simultaneously synthetic and mimetic, human and nonhuman, textual and transtextual, crafted to serve specific functions, yet difficult to control. This article explores how structuralist, cognitivist and emerging transtextual theories of literary characters have attempted to grasp and reconcile these paradoxical qualities. This allegorical cross-reading highlights previously ignored points of connection between different theories, forming a basis …
Learning to Rank Images for Complex Queries in Concept-based Search
2018
Concept-based image search is an emerging search paradigm that utilizes a set of concepts as intermediate semantic descriptors of images to bridge the semantic gap. Typically, a user query is rather complex and cannot be well described using a single concept. However, it is less effective to tackle such complex queries by simply aggregating the individual search results for the constituent concepts. In this paper, we propose to introduce the learning to rank techniques to concept-based image search for complex queries. With freely available social tagged images, we first build concept detectors by jointly leveraging the heterogeneous visual features. Then, to formulate the image relevance, …
Comparative study of historical woods from XIX century by thermogravimetry coupled with FTIR spectroscopy
2019
Thermal and structural properties of historical woods from apparatuses of the Historical Collection of the Physics Instruments of the University of Palermo have been investigated by FTIR spectroscopy coupled with thermogravimetric analysis. Specifically, the wooden portions of apparatuses from XIX century have been studied. The investigated woods belong to different taxa (Swietenia mahagoni, Picea abies and Juglans regia). The thermal behavior of the wooden materials has been successfully interpreted on the basis of specific indexes determined by the quantitative analysis of the FTIR spectra. The kinetics of the wood pyrolysis have been investigated by using a non-isothermal approach based …
Social Disparities in Education in Sub-Saharan African Countries
2007
In this paper we have two complementary objectives: the first is to describe the magnitude of social disparities that exist in the systems of education of sub-Saharan African countries; we focus on recent data but we also put these data in a time perspective. The second objective is to identify some of the factors that may explain these disparities and the impact of policies aimed at their reduction.
Evolution of common ragweed (Ambrosia artemisiifolia) resistance to herbicides : identification of genetic determinisms and application to molecular …
2022
Common ragweed (Ambrosia artemisiifolia L.), a particularly troublesome and allergenic weed, is mainly controlled in agricultural fields using ALS inhibitor herbicides. Recent cases of herbicide resistance have been reported in France and are jeopardising the efficacy of this mode of action. Both target site resistance (TSR, structural mutation in ALS gene) and non target site resistance (NTSR, regulatory and/or structural mutations in secondary metabolism) are involved. The fundamental aim of this work was to identify the genetic determinisms of resistance to ALS inhibitors that have evolved in common ragweed populations in France. As an applied objective, this work also aimed to prepare t…
In partenza verso il majhul. Italiani ed egiziani in fuga per Alessandria d'Egitto
2019
This article analyzes two novels set in Alexandria. The first one is "Cortile a Cleopatra" by the Italian writer Fausta Cialente. The second one is "Nobody sleeps in Alexandria" (Lâ ahad yanâm fî'l-Iskandariyya) by Ibrahim Abdel Meguid. The analysis focus on actions that characterize the genre of travel literature in which the traveler is expected to perform two actions: leaving then returning. If the traveler does not come back to the starting point, his experience is not considered as "travel", rather as "change of residence". But it does not always work out that way. In the two novels, the protagonists leave with intentions of ever coming back. At the same time, their departure includes …
