Universal Design for Learning: Inclusivity with Technology in Multicultural and Special Education Classrooms
This research explored the impact that technology has on students with special needs, some of whom are English Language Learners (ELL). Previous studies have found that technology brings “inclusion in the classroom helps meet the students\u27 needs and improves academic success” (Lowrey et al., 2017). Literature has also shown the value of including students and ensuring that students understand how they learn best (Brown et al.,1998). This research was conducted at an elementary school in Northern California, and included eight students with special needs, two of whom were English Language Learners. Three district personnel were also interviewed. The students\u27 participation focused on empowering them to co-create lessons amongst themselves and exploring the use of technology to learn and then teach a lesson to the class. The findings from the research showed that technology created a “fun” and inclusive environment that facilitated self-learning. It also brought awareness to the students\u27 knowledge and creativity of submitting assignments, that students could recognize multiple ways for completing work. This research has important implications toward the types of professional development and video tutorials that districts could offer teachers to help them learn new technology programs to support students with learning disabilities and who may be classified as language learners. In addition, the findings provide support to increase funding for technology, including iPads and Apple pencils, to support equity, inclusion, and the realities of learning climates for all students
Frobenius pairs in abelian categories: correspondences with cotorsion pairs, exact model categories, and Auslander-Buchweitz contexts
In this work, we revisit Auslander-Buchweitz Approximation Theory and find
some relations with cotorsion pairs and model category structures. From the
notions of relatives generators and cogenerators in Approximation Theory, we
introduce the concept of left Frobenius pairs in an
abelian category . We show how to construct from
a projective exact model structure on
, as a result of Hovey-Gillespie Correspondence applied to
two compatible and complete cotorsion pairs in . These
pairs can be regarded as examples of what we call cotorsion pairs relative to a
thick subcategory of . We establish some correspondences between
Frobenius pairs, relative cotorsion pairs, exact model structures and
Auslander-Buchweitz contexts. Finally, some applications of these results are
given in the context of Gorenstein homological algebra by generalizing some
existing model structures on the categories of modules over Gorenstein and
Ding-Chen rings, and by encoding the stable module category of a ring as a
certain homotopy category. We also present some connections with perfect
cotorsion pairs, covering classes, and cotilting modules.Comment: 54 pages, 10 figures. The statement and proof of 2.6.21 was

Competitividad local de la agricultura ornamental en México
Se muestran las características socioeconómicas y técnicas de la agricultura ornamental en las localidades de San Felipe y Buenavista, en el Estado de México, bajo un escenario de competencia y de libre mercado, además de analizar las cualidades y la influencia de esta actividad en el desarrollo local de la región.La floricultura es considerada como una actividad competitiva y vinculada con la economía global. Su práctica se limita a ciertas regiones, entre ellas el municipio de Villa Guerrero, Estado de México, cuyo potencial florícola radica en las características de los recursos naturales, así como en las condiciones sociales. Estas cualidades han favorecido la participación de las unidades de producción familiar en el mercado nacional y la ampliación de la oferta de empleo local y regional, así como el mejoramiento de los ingresos. Este trabajo muestra las características socioeconómicas y técnicas de la agricultura ornamental en las localidades de San Felipe y Buenavista, en el escenario económico de la competencia y del libre mercado

Revista DEVERAS del ComecytEl proceso productivo de la tortilla: nixtamalición y moienda del maíz, o empleo de harina de maíz nixtamalizada. La masa obtenido es la materia prima para preparar tortillas; para su fabricación, se requiere un cocimiento a 170-190°C durante 4 o 5 minutos, mismo que se lleva a cabo en planchas metálicas o de barro. La producción de tortillas representa una fuente de ingresos y una actividad económica muy importante en nuestro país. De acuerdo con el Instituto Nacional de Estadística y Geografía (INEGI), hay más de 85 mil tortillerías en nuestro país. Además, tenemos que añadir a esta actividad económica a las señoras que venden tortillas hechas a mano en los mercados locales.Consejo Mexiquense de Ciencia y Tecnologí
Generalized hydrodynamics of a dilute finite-sized particles suspension: Dynamic viscosity
We present a mesoscopic hydrodynamic description of the dynamics of colloidal
suspensions. We consider the system as a gas of Brownian particles suspended in
a Newtonian heat bath subjected to stationary non-equilibrium conditions
imposed by a velocity field. Using results already obtained in previous studies
in the field by means of a generalized Fokker-Planck equation, we obtain a set
of coupled differential equations for the local diffusion current and the
evolution of the total stress tensor. We find that the dynamic shear viscosity
of the system contains contributions arising from the finite size of the
particles.Comment: To appear in Physical Review
Non-relativistic Extended Gravity and its applications across different astrophysical scales
Using dimensional analysis techniques we present an extension of Newton's
gravitational theory built under the assumption that Milgrom's acceleration
constant is a fundamental quantity of nature. The gravitational force converges
to Newton's gravity and to a MOND-like description in two different mass and
length regimes. It is shown that a modification on the force sector (and not in
the dynamical one as MOND does) is more convenient and can reproduce and
predict different phenomena usually ascribed to dark matter at the
non-relativistic level.Comment: 4 pages, 2 figures. To appear in the proceedings of the 2011 Spanish
