Impact of the Non-Contributory Social Pension Program 70 y más on Older Adults’ Mental Well-Being

BACKGROUND In 2007, a non-contributory pension program was launched in rural areas of Mexico. The program consisted in a non-conditional cash transfer of US$40 monthly to all older adults (OA) aged 70 and over. We evaluate the effect of the program on mental well-being of its beneficiaries. METHODS AND FINDINGS Quantitative and qualitative methods were used. For the quantitative component, we...

Synthesis-Algo: An Inclusive Timetable Generating Algorithm

Timetabling manually is a complex activity that is time-consuming and stressful because a high number of high and soft constraints need to be satisfied; there is therefore the need to automate the timetabling process. Timetabling automating involves combinatorial optimization, time-based planning, realizing highly constrained problems and addressing multi-dimensional complexities. Researchers h...

Reliable spurious mode rejection using self learning algo- rithms

In this paper, we introduce a new technique for the separation of physical and spurious modes based on an initial clustering in frequency-damping space, followed by a self-learning classification algorithm. For the classification, Least Squares Support Vector Machines are used, a Least Squares version of the theory of Support Vector Machines which maps the classification problem to a high-dimen...

An Efficient Spatially Constrained EM Algo - rithm for Image Segmentation

We present a novel EM algorithm for model-based image segmentation which incorporates efficient and economical spatial constrains among pixels via a Markov random field model. We adopt a generative model in which the unobserved class labels of neighboring pixels in the image are assumed to be generated by prior distributions with similar parameters. We derive a penalized log-likelihood optimiza...
