Grounded Theory Approach

This MRP applies a grounded theory approach to a scoping review of a range of sources examining the factors driving the migration of unaccompanied children from the Northern Triangle of Central America. Four principal drivers are identified in the literature; of these, two represent push factors in the country of origin: violence and dismal economic conditions; the other two—family reunification and a perception of ease of entry into the destination country— can be construed as pull factors. I argue that the push factors are the main cause of the migration of unaccompanied children, while the pull factors represent enabling factors that facilitate this migration. Further, I also contend that, for this migration flow, violence and economic factors form a vicious cycle and therefore cannot easily be teased apart. This case therefore challenges traditional models of migration that assume a dichotomy between voluntary and forced migration. Key words: unaccompanied child migrants; Northern Triangle of Central America; drivers of migration; survival migration; push and pull factors

Pseudopotential Calculations

Single electron band structure techniques have been applied successfully to the interpretation of the near edge structures of metals and other materials. Among various band theories, the linear combination of atomic orbital (LCAO) method is especially simple and interpretable. The commonly used empirical LCAO method is mainly an interpolation method, where the energies and wave functions of atomic orbitals are adjusted in order to fit experimental or more accurately determined electron states. To achieve better accuracy, the size of calculation has to be expanded, for example, to include excited states and more-distant-neighboring atoms. This tends to sacrifice the simplicity and interpretability of the method.In this paper. we adopt an ab initio scheme which incorporates the conceptual advantage of the LCAO method with the accuracy of ab initio pseudopotential calculations. The so called pscudo-atomic-orbitals (PAO's), computed from a free atom within the local-density approximation and the pseudopotential approximation, are used as the basis of expansion, replacing the usually very large set of plane waves in the conventional pseudopotential method. These PAO's however, do not consist of a rigorously complete set of orthonormal states.

Purpose The purpose of this study was to explore the perceptions of special education practitioners (i.e., speech-language pathologists, special educators, para-educators, and other related service providers) on their role as communication partners after participation in the Social Communication and Engagement Triad (Buckley et al., 2015 ) yearlong professional learning program. Method A qualitative approach using interviews and purposeful sampling was used. A total of 22 participants who completed participation in either Year 1 or Year 2 of the program were interviewed. Participants were speech-language pathologists, special educators, para-educators, and other related service providers. Using a grounded theory approach (Glaser & Strauss, 1967 ) to data analysis, open, axial, and selective coding procedures were followed. Results Three themes emerged from the data analysis and included engagement as the goal, role as a communication partner, and importance of collaboration. Conclusions Findings supported the notion that educators see the value of an integrative approach to service delivery, supporting students' social communication and engagement across the school day but also recognizing the challenges they face in making this a reality.
