Reading in the digital age: using electronic books as a teaching tool for beginning readers
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
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
and a smooth approximation for which the sequence
of flows of has subsequences converging to different flows of the
limit vector field . 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

Smooth approximation is not a selection principle for the transport equation with rough vector field
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
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 with . Moreover, if 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 .Comment: 28 page
Agape: The Responsible Choice
In lieu of an abstract, below is the essay\u27s first paragraph.
Dr. Martin Luther Kingâs âLove, Law, and Civil Disobedienceâ 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
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  
Anton Boisen's Fellowship of the Best and the ACPE's Communities of Practice
In a 2017 address to the Eastern Region of ACPE, Ralph Ciampa explores Anton Boisenâs concept of the âfellowship of the best,â as a resource for understanding ACPEâs new structure, communities of practic
Energy conservation for 2D Euler with vorticity in
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 with 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 with

Dall'occupazione britannica all'intervento americano: storia del tormentato stato iracheno
Lâobbiettivo del mio studio Ăš stato quello di ripercorrere in modo critico la storia del paese iracheno. Lo stato, nato dallâunione delle tre province ottomane di Baghdad, Bassora e Mosul, venne assegnato per mandato alla Gran Bretagna, che, nonostante lâindipendenza 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 allâordine del giorno fino al 1979, anno in cui Saddam Husayn arrivĂČ al potere, cambiando la storia del paese.
LâIraq, 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 lâinvasione 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
United States Asylum Law: The Failure Of the United States To Accommodate Women\u27s Gender-Based Asylum Claims
