Étude longitudinale de l’orientation sociale chez les enfants avec TSA d’âge préscolaire

Resume Des etudes montrent, en situation ecologique mais egalement experimentale, que les comportements d’orientation sociale seraient reduits chez les enfants avec TSA. Nous proposons d’etudier le developpement des competences d’orientation sociale dans ces deux situations chez 13 enfants avec TSA d’âge prescolaire afin de faire le lien entre les competences lors d’une tâche experimentale et les comportements en situation de vie quotidienne. Les enfants ont ete filmes tous les mois en classe dans des situations d’interaction afin d’observer leurs comportements d’attention visuelle diriges vers un adulte (annotes a l’aide du logiciel The Observer XT10 Noldus). En parallele, ces memes enfants participent a une tâche de preference visuelle entre un visage et un objet en oculometrie. Sur le plan longitudinal, une diminution du nombre de fixations vers les visages en oculometrie est liee avec une amelioration de la duree d’orientation sociale en classe. La progression des enfants peut etre mise en lien avec leur niveau de base a la tâche, ainsi qu’avec le score obtenu aux echelles de l’ECSP en debut de suivi.
SiO Maser Survey of IRAS Sources in the Inner Galactic Disk

We have surveyed 401 color selected IRAS sources in the Galactic disk in the SiO J=1--0 v= 1 and 2 maser lines at 43 GHz, resulting in 254 (239 new) detections. The observed sources lie mostly in a strip of the inner Galactic disk with boundaries -10<l<40 deg and |b|<3 deg. This survey provides radial velocities of inner-disk stars for which optical measurements cannot be made due to interstellar extinction. The SiO $l$--$v$ diagram in the area $-10<l<40 deg exhibits fewer objects coincident with the molecular ring feature than the OH 1612 MHz source $l$--$v$ map does, indicating a slight difference of stellar type between SiO and OH emitting stars. After identifying all of the SiO detected sources in the 2MASS near-infrared catalog, we computed their luminosity distances based on the infrared fluxes. We then mapped these objects onto the first quadrant of the Galactic plane. Combining the distances with the SiO radial-velocities, we obtained a pattern speed for SiO maser sources, Omega_P=21 (+- 13) km s^{-1} kpc^{-1}, between the distances 1 and 5.5 kpc, without the use of any dynamical models. The increase of the pattern speed toward the Galactic center (up to 60 km s^{-1} kpc^{-1} between the distances, 5.5 and 7 kpc) suggests the presence of two pattern speeds in the Galaxy.
Cantharidin modulates the E2F1/MCM7-miR-106b-93/p21-PTEN signaling axis in MCF-7 breast cancer cells

Cantharidin (CTD) is one of numerous natural products used in traditional Chinese medicine for the treatment of cancer. The aim of the present study was to investigate the effects of CTD on changes in the expression of microRNAs (miRNAs/miRs) and to explore its anti-proliferative effect on MCF-7 breast cancer cells. The proliferation of MCF-7 cells was measured by performing an MTT assay. MCF-7 cells were treated with various concentrations of CTD for 48 h, and the expression profiles of miRNAs in CTD-treated and -untreated MCF-7 cells were detected using miRNA microarray chips. The array data were confirmed by reverse transcription-quantitative polymerase chain reaction and protein expression levels were measured by western blot analysis. The 50% inhibitory concentration of CTD was 1.75 µg/ml following treatment for 48 h and CTD significantly inhibited the proliferation of MCF-7 cells in a dose-dependent manner (P<0.01). Furthermore, microarray analysis identified 35 miRNAs that were up-regulated (fold change ≥2.0 and P<0.01) and 45 miRNAs that were down-regulated (fold change ≤ 0.5 and P<0.01) in response to CTD treatment. Thus, numerous CTD-induced miRNAs appeared to be associated with breast cancer. Notably, CTD repressed the expression of miR-106b-93, its host gene MCM7 and its transcription factor E2F1. In addition, CTD induced an increase in the protein expression levels of miR-106b-93 target genes p21 and phosphatase and tensin homolog. These observations suggested that the modulation of miRNA expression is an important mechanism underlying the biological effects of CTD in breast cancer.
Spectrum-blind signal recovery on graphs

We consider the problem of recovering a graph signal, sparse in the graph spectral domain from a few number of samples. In contrast to most previous work on the sampling of graph signals, the setting is “spectrum-blind” where we are unaware of the graph d support of the signal. We propose a class of spectrum-blind graph signals and study two recovery strategies based on random and experimentally designed sampling inspired by the compressed sensing paradigm. We further show sampling bounds for graphs, including Erdös-Rényi random graphs. We show that experimentally designed sampling significantly outperforms random sampling for some irregular graph families.
Effectiveness of hypermedia annotations for foreign language reading

This study first explores intermediate-level English learners' preferences for hypermedia annotations while they are engaged in reading a hypermedia text. Second, it examines whether multimedia annotations facilitate reading comprehension in the second language. The participants were 44 adult learners of English as a foreign language studying English for Academic Purposes. Data were collected through a tracking tool, a reading comprehension test, a questionnaire, and interviews. Results indicate that learners preferred visual annotations significantly more than textual and audio annotations. On the other hand, a negative relationship was found between annotation use and reading comprehension. Especially, pronunciations, audiorecordings, and videos were found to affect reading comprehension negatively. However, the qualitative data revealed that the participants had positive attitudes towards annotations and hypermedia reading in general.
Doctoral Candidate Operations and Supply Chain Management Group

The purpose of my research is to develop and empirically test a comprehensive theory of retail service design strategies. This theory will focus on the impact of physical channel design strategies on merchandise retailer effectiveness, measured in terms of satisfaction, operating, and long-term market performance. To develop this theory, I draw from a multidisciplinary literature base including organizational design, service operations management and strategy, economics, information systems, consumer marketing, and studies analyzing capital markets. This theory will enlighten future academic research and provide retail managers and store designers a method to weigh the tradeoffs associated with well-established physical channel design strategies. Retailers can test the “fit” of key design choices based on 1) retail environmental and information uncertainty and 2) firm operating and financial performance measures.
Pronouns and verbs in adult speech to children: A corpus analysis*

ABSTRACT Assessing whether domain-general mechanisms could account for language acquisition requires determining whether statistical regularities among surface cues in child directed speech (CDS) are sufficient for inducing deep syntactic and semantic structure. This paper reports a case study on the relation between pronoun usage in CDS, on the one hand, and broad verb classes, on the other. A corpus analysis reveals statistical regularities in co-occurrences between pronouns and verbs in CDS that could cue physical versus psychological verbs. A simulation demonstrates that a simple statistical learner can acquire these regularities and exploit them to activate verbs that are consistent with incomplete utterances in simple syntactic frames. Thus, in this case, surface regularities are sufficiently informative for inducing broad semantic categories. Children might use these regularities in pronoun/verb co-occurrences to help learn verbs, although whether they actually do so remains a topic of ongoing research.
The motivation toward learning among Czech high school students and influence of selected variables on motivation

Motivation toward learning is crucial factor for the students from the beginning of their education and motivation toward learning is changing during education of students and the motivation is influences by many factors. The main aims of the research was to find out the motivation of high school students toward learning, the personality traits of high school students and also relationship between motivation and personality traits. The research was also focused on the examining of variables like gender, grade level and achievement on the motivation and personality of students. The sample size was created from the high school students (n = 201). In the research were used two research tools Academic Motivation Scale and NEO Five-Factor Inventory. The gender and achievement of students had got an influence on the motivation toward learning. The relationship was detected between some subscales of motivation and some personality traits. In conclusion are presented some implications for pedagogical practice and suggestion for further research.
The Erd} Os-nagy Theorem and Its Ramiications

os-Nagy Theorem and its Rami cations Godfried Toussaint School of Computer Science McGill University Montr eal, Qu ebec, Canada June 29, 1999 Abstract Given a simple polygon in the plane, a ip is dened as follows: consider the convex hull of the polygon. If there are no pockets do not perform a ip. If there are pockets then re ect one pocket across its line of support of the polygon to obtain a new simple polygon. In 1934 Paul Erd} os introduced the problem of repeatedly ipping all the pockets of a simple polygon simultaneously and he conjectured that the polygon would become convex after a nite number of ips. In 1939 B ela Nagy pointed out that ipping several pockets simultaneously may result in a nonsimple polygon. Modifying the problem slightly he then proved that if at each step only one pocket is ipped the polygon will become convex after a nite number of ips. We call this result the Erd}os-Nagy Theorem. Since then this theorem has been rediscovered many times in di erent contexts, apparently, with none of the authors aware of each other's work. One purpose of this paper is to bring to light this \hidden" work. We review the history of this problem, provide a simple elementary proof of a stronger version of the theorem and consider variants, generalizations and applications of interest in computational knot theory, polymer physics and molecular biology. We also improve several results in the literature with the application of the Erd}os-Nagy theorem. We close with a list of open problems.

Probalistic Learning Approaches for Indexing and Retrieval with the TREC-2 Collection

In this paper, we describe the applicaion of probabilistic models for indexing and retrieval with the TREC-2 collection. This database consists of about a million documents (2 gigabytes of data) and 100 queries (50 routing and 50 adhoc topics). For document indexing we use a description -oriented approach which exploits relevance data in order to produce a probabilistic indexing with single terms as well with phrases. With the adhoc queries, we present a new query term weighting method based on a training sample of other queries. For the routing queries, the RPI model is applied which combines probabilistic indexing with query term weighting based on query-specific feedback data. The experimental show very good performance for both types of queries
Simulation Study of the Generalized Predictive Control Algorithm Based on BP MFN's Model

For the present, there are still difficulties to construct many steps predictive models and its control laws for the strong nonlinear systems, though the generalized predictive control (GPC) algorithm had been obtained well control effect to the linear or weak nonlinear systems. For solving the questions, based on the high nonlinear mapping property of BP multilayer feedforward network (MFN) model, the control method which is GPC's algorithm with the artificial neural network technologies is studied. The GPC's control structure scheme based on BP MFN's model for the nonlinear system is designed. The GPC's control principle, control algorithm and setting different parameters of the GPC criterion function are analysed. Finally, simulation researches of GPC's algorithm for the nonlinear system based on the BP MFN's model have done. Simulation results show, the GPC's control structure scheme based on BP MFN's model is effective and GPC's algorithm based on BP MFN's model is successful
Spatial scaling of regional strategic programmes in Finland: A qualitative study of clusters and innovation systems

Innovation systems and clusters are perhaps the most widely used concepts found in recent economic geography literature focusing on innovative industrial production and locational agglomeration. Both concepts have been universally embraced since the early 1990s onwards. However, recent literature has expressed criticism of their use as tools for policymaking. The authors studied innovation and cluster rhetoric in a geographical context by using empirical evidence obtained from the policy documents of the Finnish regional councils. They used a theoretical conception of spatial scaling as a geographical framework. Spatial scales proved to be a black box for regional strategies in Finland. Regional strategic programmes use a similar language that ignores the spatial variations of their locations. Clusters and regional innovation systems should be considered as parts of vertical and horizontal interlinkages within the economy and not as individual islands of organizational proximities in isolated contexts. The authors argued that an imprecise understanding of the innovation systems and cluster approaches, both conceptually and practically, has led to some ambiguity, resulting in the use of the terms clusters and innovation systems as buzzwords. This misuse hampers the ability of administrations to execute regional development in their respective areas.
Knowledge co-creation in the OrganiCity: Data annotation with JAMAiCA

Numerous smart city testbeds and system deployments have surfaced around the world, aiming to provide services over unified large heterogeneous IoT infrastructures. Although we have achieved new scales in smart city installations and systems, so far the focus has been to provide diverse sources of data to smart city services consumers, while neglecting to provide ways to simplify making good use of them. We believe that knowledge creation in smart cities through data annotation, supported in both an automated and a crowdsourced manner, is an aspect that will bring additional value to smart cities. We present here our approach, aiming to utilize an existing smart city deployment and the OrganiCity software ecosystem. We discuss key challenges along with characteristic use cases, and report on our design and implementation, along with preliminary results.
Investigating the mechanisms and processes of player-avatar relationship construction : a dual process of experiential and psychological interpretation during game play

Research into player-avatar relationship have found that players are able to experience different levels of emotional attachment, agency, embodiment, and identification with their game avatar. While current literature mostly addresses the psychological processes that form different types of player-avatar relationship, lesser is known about the mechanisms and processes of player-avatar relationship construction. Hence, the current study explores how game play experiences and the interpretation of game mechanics help players rationalize their relationship with game avatars. 28 adults who played an action adventure PS4 game, The Last of Us, participated in game play interviews and semi-structured in-depth interviews. Thematic analysis of the results revealed six different themes that explain the mechanisms that link players’ gameplay experiences to their relationship with the game avatar. Subsequently, this paper discusses three major tendencies in which players may construct player-avatar relationships and the processes of player-avatar relationship construction.
Integration or isolation: experiences of Irish students during their study abroad in Spain or Latin America

ABSTRACT Time abroad is an ever more common feature of study for many university students. Students of languages, in particular, are encouraged or required to spend a period of time abroad as an integral component of their degree. While research on study abroad is abundant, studies addressing the socialisation of Irish students during their time abroad are limited. In an effort to better understand this issue, the research reported in this paper examined factors that enhanced or hindered students of Spanish from an Irish university integrating into a host country/city during two academic semesters spent at partner universities in Spain or Latin America. Students completed an online survey on their return home in order to ascertain their experiences of integration in the local communities where they lived. Results show that students who made efforts to join sport/social activities and who engaged in activities with native speakers of Spanish had a positive experience of integration. This paper also makes recommendations that may be relevant for students and institutions in their preparation for study abroad.
Study on Art Gallery Based on 4-coloring

It isn't the best result on the art gallery based on the 3-coloring in resolving the most of simple polygons, through a analysis of the simple polygon triangulation in the relationship between adjacent triangles, using the dual relation between triangulation and binary tree, this paper puts a forward 4coloring on the polygon triangulation, and analyze and research the case which has been 4-coloring. we can obtain some results that the condition of any type of colors could cover the whole polygon, and the condition that at least one type of colors could cover the whole polygon (namely the art gallery only need for monitors), we also analyzing the reason which failed to cover the whole polygon, and presenting the condition which couldn't be 4-colored.

Modified PROPELLER approach for T2‐mapping of the abdomen

Quantitative abdominal T2 measurements may be useful for lesion differentiation and functional tissue characterization. However, T2 mapping of the abdomen with conventional spin‐echo (SE) and turbo‐spin‐echo (TSE) approaches can be challenging due to physiologic motion artifacts. Multishot TSE‐based PROPELLER (Periodically Rotated Overlapping ParallEL Lines with Enhanced Reconstruction) can provide superior image quality due to reduced sensitivity to motion artifacts. With echo‐reordering to accurately estimate effective echo times and an extended slice thickness ratio to reduce stimulated echo effects, a modified PROPELLER approach may permit accurate, robust abdominal T2 measurements. We validated the accuracy of our modified PROPELLER T2‐mapping approach by comparison to conventional SE measurements in a phantom model and demonstrated the feasibility of acquiring accurate, high‐quality abdominal T2 maps in normal volunteers.

Revisiting public debate on Genetic Modification and Genetically Modified Organisms. Explanations for contemporary Dutch public attitudes

Genetic Modification (GM) has been a topic of public debates during the 1990s and 2000s. In this paper we explore the relative importance of two hypothesized explanations for these controversies: (i) people's general attitude toward science and technology and (ii) their trust in governance, in GM actors, and in GM regulations, in explaining the Dutch public's Attitude toward GM applications, and in addition to that, the public's GM Information seeking behaviour. This will be conducted through the application of representative survey methodology. The results indicate that Attitudes toward GM applications are best predicted by both the attitude toward science and technology and three trust measures. GM information seeking is predicted by gender and educational level, as well as attitude toward science and technology, trust in organisations and trust in regulations (negative). Overall, psychological variables seem better predictors than demographics. Implications for future research on information seeking behaviour are discussed.
Coordination Games with vanishing Actions

We deal with n-player coordination games with vanishing actions, which are repeated games where all non-diagonal entries yield zero-payoffs, and where, moreover, at any stage beyond ri any player i loses any action that she has not used during the previous ri stages of play. For these games we examine the set of equilibrium rewards, where we treat the two-player case and the more player case separately. Folk-theorem like results are established.
Parenting infants: the role of mothers’ perceptions of how they were parented

ABSTRACT This study investigated women’s perceptions of caring and control in their fathers versus their mothers in relation to specific ways in which they interacted with their infants during freeplay. Participants were 73 mothers and their 6 month-old infants. Results revealed that women’s perceptions about their mothers compared to their fathers in the same domain of parenting can have differing relations with various aspects of their own parenting, such as infant-directed speech and positive engagement with their infants. Specific parenting behaviours related differentially to women’s perceptions about their parents. These associations were independent of global predictors of early parenting such as women’s depressive status. Findings could have implications for targeting prevention and intervention efforts to mothers at risk for less positive parenting. How controlling or caring they remember their parents to be could serve as a protective factor or convey additional risk depending on the gender of their parents.
