SMQ / VOL. XII / NO. 1 / SPRING 2006 ABSTRACT Partnership development for national social marketing campaigns is a much copied, but poorly researched, area of practice. As part of the development of Phase II of the Centers for Disease Control’s National Bone Health Campaign, several needs-assessment and market analysis activities were conducted to develop partnership strategies that were respon...

Computer animation has been a popular research topic since 1970s, when the first parametric facial model is proposed[0]. In the recent few years, a lot of techniques are proposed to model and animate faces like physical modelling, motion capture, mesh deformation etc. However, most of them require burden work of artists and assistance of expensive model. Rigging is one kind of the most popular ...

In the 1960s the isolated tropical forest enclave of Quintana Roo was targeted by the Mexican Government to serve as the cornerstone for launching what is now considered to be one of Mexico’s most successful economic development strategies – Planned Tourism Development (PTD). This paper commences with a brief review of the role of state-driven PTD in Mexico’s national economic development agend...

Across two years, we examined the effects of teachers’ attempts to implement computer supported collaborative learning (CSCL) communities in classrooms in two high schools on students’ knowledge building, strategic learning, and perceptions of the classroom environment. In year one, 429 (fall) and 317 (spring) students in the classes of 8 teachers and in year two, 946 students in the classes of...

the molecular weight distribution of 4 commercial isotactic polypropylene (ipp) samples was estimated using rheological data. the dynamic moduli data, obtained from rheological measurements in linear viscoelastic region was used for calculation of relaxation time spectrum, h(τ) and then shear relaxation modulus, g(t). finally, applying thimm kernel function and relaxation modulus data in genera...

In this work, by replacing the traditional solid spokes with colloidal spokes, a vehicle wheel with a built-in suspension structure is proposed. Following the background and description of the wheel system, firstly, a vibration model of the wheel equipped with colloidal spokes is proposed, and based on such model the equivalent damping coefficients and spring constants are identified. Then, a m...

The Yoneda Lemma tells us that the Hom bifunctor is “non-degenerate” in a similar way. (a) For each object X ∈ C verify that hX := HomC(X,−) defines a functor C → Set. (b) Given two objects X,Y ∈ C state what it means to have hX ≈ hY as functors. (c) Given two objects X,Y ∈ C and an isomorphism of functors hX ≈ hY , prove that we have an isomorphism of objects X ≈ Y . [Hint: Let Φ : hX ∼ −→ hY ...
