    This study investigated the eBook reading experiences of eight grade 1 students. Eight students were given ten 25-minute sessions with the software programs over 15 weeks. Qualitative data were collected from students, teachers, and parents through questionnaires, interviews, observations and field notes.The results suggest the promise of electronic books in enhancing the reading motivation of beginning readers.Beginning readers\u27 motivation to read and the texts they choose to read impact on their literacy achievement and willingness to engage with reading activities in the primary years of schooling

    On smooth approximations of rough vector fields and the selection of flows

    Get PDF
    In this work we deal with the selection problem of flows of an irregular vector field. We first summarize an example from \cite{CCS} of a vector field bb and a smooth approximation bϔb_\epsilon for which the sequence XϔX^\epsilon of flows of bϔb_\epsilon has subsequences converging to different flows of the limit vector field bb. Furthermore, we give some heuristic ideas on the selection of a subclass of flows in our specific case.Comment: Proceeding of the "XVII International Conference on Hyperbolic Problems: Theory, Numerics, Applications.

    Smooth approximation is not a selection principle for the transport equation with rough vector field

    Get PDF
    In this paper we analyse the selection problem for weak solutions of the transport equation with rough vector field. We answer in the negative the question whether solutions of the equation with a regularized vector field converge to a unique limit, which would be the selected solution of the limit problem. To this aim, we give a new example of a vector field which admits infinitely many flows. Then we construct a smooth approximating sequence of the vector field for which the corresponding solutions have subsequences converging to different solutions of the limit equation.Comment: 22 pages, 4 figure

    Weak solutions obtained by the vortex method for the 2D Euler equations are Lagrangian and conserve the energy

    Get PDF
    We discuss the Lagrangian property and the conservation of the kinetic energy for solutions of the 2D incompressible Euler equations. Existence of Lagrangian solutions is known when the initial vorticity is in LpL^p with 1≀p≀∞1\leq p\leq \infty. Moreover, if p≄3/2p\geq 3/2 all weak solutions are conservative. In this work we prove that solutions obtained via the vortex method are Lagrangian, and that they are conservative if p>1p>1.Comment: 28 page

    Agape: The Responsible Choice

    In lieu of an abstract, below is the essay\u27s first paragraph. Dr. Martin Luther King‟s “Love, Law, and Civil Disobedience” offers an important message today as it did when it was given in 1961. The essential message is one of love and respect for our fellow man, and can we honestly look at our society today and claim we have reached a point of love and respect for all people? When we examine recent events, health care reform, issues in education, war, and immigration, we should realize we still have a ways to go

    Electronic Storybooks: A Constructivist Approach to Improving Reading Motivation in Grade 1 Students

    Get PDF
    This study stemmed from a concern of the perceived decline in students’ reading motivation after the early years of schooling. This research investigated the effectiveness of online eBooks on eight grade 1 students’ reading motivation. Eight students were given ten 25-minute sessions with the software programs over 15 weeks. Qualitative data were collected from students, teachers, and parents through questionnaires, interviews, observations and field notes. The results suggest the promise of online reading software programs in supporting early readers with reading, motivation, and/or behavioural difficulties.  Keywords: digital reading; early literacy; reading motivation; online; eBooks; constructivism &nbsp

    Energy conservation for 2D Euler with vorticity in L(log⁥L)αL(\log L)^\alpha

    Get PDF
    In these notes we discuss the conservation of the energy for weak solutions of the two-dimensional incompressible Euler equations. Weak solutions with vorticity in Lt∞LxpL^\infty_t L^p_x with p≄3/2p\geq 3/2 are always conservative, while for less integrable vorticity the conservation of the energy may depend on the approximation method used to construct the solution. Here we prove that the canonical approximations introduced by DiPerna and Majda provide conservative solutions when the initial vorticity is in the class L(log⁥L)αL(\log L)^\alpha with α>1/2\alpha>1/2.Comment: arXiv admin note: text overlap with arXiv:1905.0972

    Dall'occupazione britannica all'intervento americano: storia del tormentato stato iracheno

    Get PDF
    L’obbiettivo del mio studio Ăš stato quello di ripercorrere in modo critico la storia del paese iracheno. Lo stato, nato dall’unione delle tre province ottomane di Baghdad, Bassora e Mosul, venne assegnato per mandato alla Gran Bretagna, che, nonostante l’indipendenza del paese ottenuta nel 1932, continuĂČ ad avere una forte influenza sul paese. A causa della sua controversa composizione, la cospirazione e i colpi di stato furono all’ordine del giorno fino al 1979, anno in cui Saddam Husayn arrivĂČ al potere, cambiando la storia del paese. L’Iraq, desideroso di erigersi a potenza regionale, iniziĂČ una politica estera aggressiva che lo portĂČ a dichiarare guerra a Iran e Kuwait a distanza di pochi anni. Le conseguenze di queste decisioni avventate e l’invasione americana nel 2003 hanno avviato il paese ad una completa disintegrazione, riproponendo il problema di inizio Novecento: sunniti, sciiti e curdi sono oggi in lotta tra di loro a difesa dei propri interessi. La nazione irachena forse non Ăš mai nata
