Research review: reading comprehension in developmental disorders of language and communication

Background: Deficits in reading airment (SLI), Down syndrome (DS) and autism spectrum disorders (ASD). Methods: In this review (based on a search of the ISI Web of Knowledge database to 2011), the Simple View of Reading is used as a framework for considering reading comprehension in these groups. Conclusions: There is substantial evidence for reading comprehension impairments in SLI and growing evidence that weaknesses in this domain are common in DS and ASD. Further, in these groups reading comprehension is typically more impaired than word recognition. However, there is also evidence that some children and adolescents with DS, ASD and a history of SLI develop reading comprehension and word recognition skills at or above the age appropriate level. This review of the literature indicates that factors including word recognition, oral language, nonverbal ability and working memory may explain reading comprehension difficulties in SLI, DS and ASD. In addition, it highlights methodological issues, implications of poor reading comprehension and fruitful areas for future research.

THE EXTENT OF MULTIDISCIPLINARY AUTHORSHIP OF ARTICLES ON SCIENTOMETRICS AND BIBLIOMETRICS IN BRAZIL

The publications in scientometrics and bibliometrics with Brazilian authorship expanded exponentially in the 1990-2006 period, reaching 13 times in the Web of Science database and 19.5 times in the Google Scholar database. This increase is rather superior to that of the total Brazilian scientific production in the same time period (5.6 times in the Web of Science). Some characteristics to be noticed in this rise are: 1) The total number of articles during this period was 197; in that, 78% were published in 57 Brazilian journals and 22% in 13 international journals. 2) The national and international articles averaged 4.3 and 5.9 citations/article, respectively; two journals stood out among these, the national Ciencia da Informacao (44 articles averaging 6.7 citations/article) and the international Scientometrics (32 articles averaging 6.2 citations/article). 3) The articles encompass an impressive participation of authors from areas other than information science; only one-fourth of the authors are bound to the information science field, the remaining ones being distributed among the areas of humanities/business administration, biology/biomedicine, health and hard sciences. The occurrence of adventitious authors at this level of multidisciplinarity is uncommon in science. However, the possible benefits of such patterns are not clear in view of a fragmented intercommunication among the authors, as noticed through the citations. The advantages of changing this trend and of using other scientometric and bibliometric databases, such as SciELO, to avoid an almost exclusive use of the Web of Science database, are discussed.

Análise da produtividade científica dos docentes da Universidade Estadual Paulista, campus de Marília/SP

O objetivo do presente trabalho foi analisar/quantificar a produtividade científica dos docentes pertencentes à Universidade de Estadual Paulista (UNESP), campus de Marília/SP. Para cada professor, analisamos o número total de artigos na plataforma Lattes, no ISI Web of Science e no SCOPUS. Além disso, verificamos o total de livros publicados, capítulos de livros publicados e orientações em Programas de Pós-Graduação (PPG). A análise dos nove departamentos da Faculdade de Filosofia e Ciências (FFC) mostrou que o Departamento de Ciências Políticas e Econômicas possui uma média elevada (21,42) de artigos na Plataforma Lattes, quando comparado aos outros departamentos. Entretanto, o Departamento de Fonoaudiologia apresentou médias mais altas em artigos indexados pelo ISI (2,61) e SCOPUS (4,39), bem como o índice-h, nessas plataformas. em relação aos programas de pós-graduação, o Departamento de Administração e Supervisão Escolar foi o que apresentou a maior média de orientações em andamento e/ou concluídas. O desempenho mais baixo, em relação aos artigos publicados pelo ISI e SCOPUS, pelos departamentos na área de Humanas/Humanidades pode estar associado às características do campo da concentração e da cobertura limitada do banco de dados ISI e SCOPUS, indicando que o índice-h é muito sensível ao campo de concentração.

Produção científica na faculdade de filosofia, ciencias e letras de ribeirao preto-usp: Apliçãcao do índice de hirsch

In this work, an analysis of scientific bibliographic productivity was made using the Faculdade de Filosofia, Ciencias e Letras de Ribeirao Preto, Universidade de Sao Paulo (FFCLRP-USP) as example. It is a special Institution in the Brazilian University system which encompasses four important areas of knowledge (fields of concentration) in natural, biological, humanities, and social areas. It is composed by four departments which offer altogether eight undergraduate courses: 1) Psychology, 2) Pedagogy, 3) Chemistry, 4) Biology, 5) Medical Physics, 6) Biomedical Informatics, 7) Sciences of Information and Documentation and 8) Mathematics Applied to Business and six graduate programs leading to M.S. and Ph.D. degrees. Moreover, when analyzing the different courses of FFCLRP, they represent typical academic organization in Brazil and Latin America and could be taken as a model for analyzing other Brazilian research institutions. This analysis was made using: 1) the total number of papers (indexed in Curriculum Lattes database), 2) the number of papers indexed by Thomson ISI Web of Science database, and 3) the Hirsch (h-index). Bibliometric evaluations of undergraduate courses showed a better performance of the courses of Chemistry (P < 0.05), Biology (P < 0.05) and Medical Physics (P < 0.05) when compared to the Pedagogy, Sciences of Information and Documentation (P < 0.05) and Psychology (P < 0.05). We also analyzed the scientific output of the six graduate programs of FFCLRP-USP: 1) Chemistry, 2) Physics Applied to Medicine and Biology, 3) Entomology, 4) Compared Biology, 5) Psychology, 6) Psychobiology. The graduate programs in Psychobiology, Chemistry, Physics Applied to Medicine and Biology, Compared Biology, and Entomology presented very similar results, concerning the assessment of the three indexes. The graduate program in Psychology presented a lower h-index (P < 0.05) and had fewer papers indexed by the ISI (P < 0.05) when compared to the other graduate programs. The worse performance of the psychology program, pedagogy, sciences of information and documentation, psychology courses may be associated to the limited coverage of ISI database and some particular characteristics of this field of concentration.

Scientific research output evaluation of professors of Sao Paulo State University, Marilia/SP

In this work, an analysis of scientific bibliographic productivity was made using the Faculdade de Filosofia e Ciencias, Universidade Estadual Paulista (FFC-UNESP) as example. It is composed by nine departments which offer altogether nine undergraduate courses: 1) Archival, 2) Library, 3) Speech Therapy, 4) Pedagogy, 5) International Relations, 6) Physiotherapy, 7) Occupational Therapy, 8) Philosophy, 9) Social Sciences and six graduate programs leading to M. S. and Ph.D. degrees. Moreover, when analyzing the different courses of FFC-UNESP, they represent typical academic organization in Brazil and Latin America and could be taken as a model for analyzing other Brazilian research institutions. Using data retrieved from the Lattes Plataform database (Curriculum Lattes) we have quantitatively the scientific productivity percentage of professors at UNESP. We observed that bibliometric evaluations using the Curriculum Lattes (CL) showed that the professors published papers in journal are not indexed by ISI and SCOPUS. This analysis was made using: 1) the total number of papers (indexed in Curriculum Lattes database), 2) the number of papers indexed by Thomson ISI Web of Science database and SCOPUS database, and 3) the Hirsch (h-index) by ISI and SCOPUS. Bibliometric evaluations of departments showed a better performance of Political Science and Economics Department when compared to others departments, in relation total number of papers (indexed in Curriculum Lattes database). We also analyzed the academic advisory (Master's Thesis and Ph. D. Thesis) by nine departments of FFC/UNESP. The Administration and School Supervision Department presented a higher academic advisory (concluded and current) when compared to the others departments.

Ubuntu phone - un sistema operativo convergente per desktop e cellulari

Ubuntu Touch è un nuovo sistema operativo per Desktop e Cellulari che nasce dalla necessità di unire sistemi eterogenei sotto un'unica piattaforma. L'infrastruttura di Touch, che garantisce convergenza fra dispositivi diversi, è basata sull'innovativo server grafico Mir e sull'interfaccia grafica Unity. L'Application Model è notevolmente migliorato, le applicazioni sono confinate attraverso AppArmor, e scambiano fra loro contenuti tramite il servizio Content-Hub. I tool di sviluppo supportati sono le tecnologie web (HTML5 e JavaScript) e C++ su Framework Qt (possibilità di utilizzare QML). Gli aggiornamenti di sistema, del core, sono sia parziali, attraverso archivi "delta" che introducono solo i cambiamenti necessari, sia full, sovrascrivono l'intero dispositivo. Lo sviluppo in Ubuntu SDK è veloce e agile. Notevole la gestione degli emulatori, ma pecca di alcune feature tutt'ora mancanti. Gli Scope sono application content indipendent, vera innovazione in Ubuntu. Per sperimentare questa tecnologia si sviluppa uno scope per la ricerca di libri nella Biblioteca Gian Paolo Dore della Facoltà di Ingegneria di Bologna.

Infine è stata effetuata un'analisi dei risultati dell'errore prodotto dall'interpolazione.

App Ibrida per l’apprendimento della matematica attraverso esercizi di logica

Nell’ambito di questo lavoro di tesi è stata progettata e realizzata un'applicazione di edutainment, pensata per essere fruita attraverso dispositivi mobili, da parte di studenti delle scuole medie, con l’obiettivo di esercitare e migliorare le capacità logiche e di problem solving. La tesi descrive il contesto educativo e scolastico in relazione alla presenza delle tecnologie dell'informazione e della comunicazione, ed infine mostra come una componente di intrattenimento possa essere utile nei processi di apprendimento. Lo sviluppo dell’applicazione è basato sulla progettazione di applicazioni ibride, usando come framework di sviluppo Apache Cordova, quindi attraverso tecnologie web-based, con un’architettura client-server, in cui la parte client gestisce l’interfaccia grafica e le interazioni logiche mentre la parte server viene sfruttata esclusivamente come contenitore di informazioni.

Uses and misuses of the STROBE statement: bibliographic study

Objectives Appropriate reporting is central to the application of findings from research to clinical practice. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations consist of a checklist of 22 items that provide guidance on the reporting of cohort, case-control and cross-sectional studies, in order to facilitate critical appraisal and interpretation of results. STROBE was published in October 2007 in several journals including The Lancet, BMJ, Annals of Internal Medicine and PLoS Medicine. Within the framework of the revision of the STROBE recommendations, the authors examined the context and circumstances in which the STROBE statement was used in the past. Design The authors searched the Web of Science database in August 2010 for articles which cited STROBE and examined a random sample of 100 articles using a standardised, piloted data extraction form. The use of STROBE in observational studies and systematic reviews (including meta-analyses) was classified as appropriate or inappropriate. The use of STROBE to guide the reporting of observational studies was considered appropriate. Inappropriate uses included the use of STROBE as a tool to assess the methodological quality of studies or as a guideline on how to design and conduct studies. Results The authors identified 640 articles that cited STROBE. In the random sample of 100 articles, about half were observational studies (32%) or systematic reviews (19%). Comments, editorials and letters accounted for 15%, methodological articles for 8%, and recommendations and narrative reviews for 26% of articles. Of the 32 observational studies, 26 (81%) made appropriate use of STROBE, and three uses (10%) were considered inappropriate. Among 19 systematic reviews, 10 (53%) used STROBE inappropriately as a tool to assess study quality. Conclusions The STROBE reporting recommendations are frequently used inappropriately in systematic reviews and meta-analyses as an instrument to assess the methodological quality of observational studies.

Hybridization and Introgression Between Native and Alien Species

Human activities, such intentional and unintentional transplantations, and habitat alterations including the establishment of migration corridors, generate increasing opportunities for formerly allopatric taxa to meet and to hybridize. There is indeed increasing evidence that these introduced plant and animal taxa (including crop plants and domesticated animal taxa) frequently hybridize with native relatives and with other introduced taxa, leading to a growing concern that these hybridizations may compromise the genetic integrity of native taxa to the point of causing extinctions (Abbott 1992; Rhymer and Simberloff 1996; Levin et al. 1996; Ellstrand and Schierenbeck 2000; Vilà et al. 2000). A decade ago, Rhymer and Simberloff (1996) stated in their review on this topic that the known cases are probably just the tip of the iceberg.Using the search term ‘hybridization and introgression’, the Web of Science database yields a total of 1,178 research articles, of which 935 (or 80 %) have been published after 1995 (Fig. 16.1). Indeed, the evidence for natural and man-induced hybridization and introgression appears to have increased exponentially these last few years.

Barriers to the adoption of photovoltaic systems: The state of the art

Although photovoltaic (PV) systems have become much more competitive, the diffusion of PV systems still remains low in comparison to conventional energy sources. What are the current barriers hindering the diffusion of PV systems? In order to address this, we conducted an extensive and systematic literature review based on the Web of Science database. Our state-of-the-art review shows that, despite the rapid development and maturity of the technology during the past few years, the adoption of PV systems still faces several barriers. The wide adoption of PV systems-either as a substitute for other electricity power generation systems in urban areas or for rural electrification-is a challenging process. Our results show that the barriers are evident for both low- and high-income economies, encompassing four dimensions: sociotechnical, management, economic, and policy. Although the barriers vary across context, the lessons learned from one study can be valuable to others. The involvement of all stakeholders-adopters, local communities, firms, international organizations, financial institutions, and government-is crucial to foster the adoption.

Gamification e rilevazione di barriere architettoniche: un caso di studio con applicazioni mobili

Questo volume di tesi descrive lo sviluppo di un'applicazione cross-platform per la raccolta dati sull'accessibilità urbana. E' stato creato un Pervasive GWAP strutturato in modo tale da raccogliere, tramite un gioco in mixed-reality, dati sulla geolocalizzazione delle barriere/facility architettoniche in ambiente urbano, in modo da mappare il territorio. Il gioco è rivolto a bambini accompagnati da insegnanti/genitori e prevede l'utilizzo di dispositivi mobili quali tablet e smartphone con sistema operativo Andoid. E' stata utilizzata la funzione GPS dei dispositivi per la geolocalizzazione dei giocatori e delle barriere/facility segnalate e la CAMERA per lo scan dei Qr-Code utilizzati come incentivo per intrattenere gli utenti. L'applicazione è scritta utilizzando tecnologie web quali HTML, CSS, JavaScript, PHP, JSON e grazie all'utilizzo del framework Apache Cordova è stato possibile lo sviluppo multipiattaforma. Questo strumento permette di utilizzare tecnologie web per lo sviluppo di applicazioni mobile, generando codice nativo supportato da sistemi operativi quali Android, iOS, BlackBerry.

Analisi della piattaforma Nutch
