The max-k-cut problem is to partition the vertices of a weighted graph G = (V, E) into k ≥ 2 disjoint subsets such that the weight sum of the edges crossing the different subsets is maximized. The problem is referred as the max-cut problem when k = 2. In this work, we present a multiple operator heuristic (MOH) for the general max-k-cut problem. MOH employs five distinct search operators organi...

Health planners commonly use geographic proximity to define access to health services. However, effective access to case management requires reliable access to a trained, supplied provider. We defined effective access as the proportion of the study population with geographic access, corrected for other barriers, staffing patterns, and medicine availability. We measured effective access through ...

Excessive medication intake is a risk factor for the development of medication-overuse headache (MOH), a condition characterized by an increase of headache frequency to a daily or near-daily pattern. As yet, it is largely unknown why some patients overuse medication. In this study, we examined to what extent attitudes about pain medication, especially perceived need and concerns, and problem-so...

Background: It is unknown if medication-overuse headache, clinically similar to chronic tension-type headache, has pre-attentive problems which may be related to pain or substance abuse. Methods: Auditory frequency deviance elicited mismatch negativity was recorded from 22 patients with chronic tension-type headache, 26 with medication-overuse headache from underlying chronic tension-type heada...

As part of a multifaceted effort to respond to the needs of young people more effectively, the Ministry of Health of the Republic of Moldova established pilot Youth Friendly Health Centres (YFHC) in 2001. In 2005, after 12 YFHC were set up and implemented, the MOH identified that while they were serving a useful function, four problems remained needed to be addressed - the lack of an operationa...
