The American University of Armenia is a private, nonsectarian, independent university founded in 1991 in Yerevan, Armenia. Its creation inspired in the aftermath of the 1988 Armenian earthquake, the university is the first Armenian institution modeled on Western-style higher education, committed to teaching, research, and service. The university currently offers instruction leading to a master's degree in the following eight fields of study: business administration, industrial engineering and systems management, computer and information science, political science, public health, law, comparative legal studies, and teaching English as a foreign language. Since 2013 university started providing undergraduate education in the following fields: computational science, business, English and communication By offering these programs in English, AUA strives to become accessible to qualified individuals from other countries in the region.Qualified students may complete an interdisciplinary Certificate in Environmental Conservation and Research. In preparation for the academic program, AUA offers its students instruction in the English language and in computer applications. Wikipedia.

Background An estimated 23 million Americans have asthma, of whom at least 12 million experience an asthma exacerbation every year. Clinical practice guidelines focus on asthma control, with an emphasis on reducing both impairment and risk. Objective We sought to explore broad patterns of asthma prevalence, self-reported medication use, and indicators of control in a nationally representative sample. Methods The 2008, 2009, and 2010 Medical Expenditure Panel Surveys were used to examine the national prevalence of self-reported asthma, trends in medication use, and demographic characteristics of asthmatic patients. History of lifetime asthma and current diagnosis were ascertained based on self-report. Asthma management and control were examined by using patient-reported medication use. Results Of the 102,544 subjects asked about an asthma diagnosis, 9,782 reported lifetime asthma, and 8,837 reported current asthma. Five thousand five subjects (4.8% of the population) reported experiencing an asthma exacerbation in the previous year. Four thousand five hundred twenty-one subjects used a quick-relief inhaler for asthma symptoms, and 14.6% used more than 3 canisters of this type of medication in the past 3 months. Of this group, 60% were using daily long-term control medication but still required significant use of quick-relief inhalers, whereas 28% had never used long-term control medication. Of those who had a recent exacerbation, 29% were using daily preventive medication, whereas 54% had never used long-term control medication. Conclusions Improvement of asthma control continues to be a US public health concern. Results suggest suboptimal asthma control with underuse of long-term control medications, overuse of quick-relief inhalers, and a significant number of self-reported asthma exacerbations. © 2014 American Academy of Allergy, Asthma & Immunology.

More than half a century after the debut of CPM and PERT, we still lack a project scheduling system with calibrated and validated distributions and without requiring complex user input. Modern decision support systems (DSS) for project management are more sophisticated and comprehensive than PERT/CPM. Nonetheless, in terms of stochastic analysis, they show insufficient progress. PERT 21 offers a radically different stochastic analysis for projects, based on relevant and validated theory. Operationally, it is sophisticated yet simple to use. It is designed to enhance existing DSS, and thus it can be implemented without sacrificing the investment already made in project management systems. Finally, regarding the important sequencing and crashing models developed under CPM, PERT 21 permits their adaptation to stochastic reality. © 2011 APM and IPMA and Elsevier Ltd. Source

This cross-sectional study identified the prevalence of gender based violence (GBV) and examined its association with sexual risk behavior among female sex workers (FSWs). Among 120 participants between ages 20 and 52, a total of 56.7 % reported lifetime GBV. Multivariate analyses revealed that GBV was significantly associated with inconsistent condom use, unprotected sex, condom misuse, fear of client reaction to requests of condom use, self-reported history of STIs, and earlier age of initiation of sex work. GBV must be considered an urgent public health priority among FSWs in Armenia. Interventions addressing FSWs, in addition to targeting skill-based, sexual risk reduction must also introduce a discourse among FSWs, sexual partners, clients and community members about the role of GBV in HIV-associated risk behaviors and infection. Structural level initiatives must address economic opportunities for women, health-sector policies and responses to FSWs' health needs, law enforcement training and societal norms toward women. © 2012 Springer Science+Business Media, LLC.

We evaluated the cost-effectiveness of PCI with DES versus CABG in terms of preventing MACE (composite outcome of myocardial infarction (MI), repeat revascularization (RR), and death) after four years of procedure among patients with ischemic heart disease (IHD) treated at NMMC from January 1 2004 to December 31 2005. Patients who were more than 70 years old, who had prior revascularization (CABG or PCI), cardiogenic shock, end-stage renal disease defined as a serum creatinine>2 mg/dl, severe left ventricular dysfunction defined as a left ventricular ejection fraction<30%, or cancer at the time of admission were excluded from the sample. We also excluded patients whose procedures were covered by the Ministry of Health of Armenia (3 patients at the time of study). PCI and CABG patients were matched 1:1 for three important predictors that may potentially affect the selection of procedures and the outcomes--age (±3 years), gender, and diabetes mellitus status. Patients in the CABG group had significantly longer event-free survival times than patients in the PCI group (p<0.037, unadjusted difference) in 4.2 years of follow-up. CABG was less costly by $6,540 with preventing one more MACE compared to PCI with DES. According to our findings, CABG is a more cost-effective strategy than PCI with DES in terms of preventing RR, MI and death and saving costs. Prospective evaluation with longer time horizon would add more information to the results of our study, since the number of patients referred to the PCI replacement is increasing, the pricing is frequently changing, and there are new technologies in development.

An important class of economic models involve agents whose wealth changes due to transactions with other agents. Several authors have pointed out an analogy with kinetic theory, which describes molecules whose momentum and energy change due to interactions with other molecules. We pursue this analogy and derive a Boltzmann equation for the time evolution of the wealth distribution of a population of agents for the so-called Yard-Sale Model of wealth exchange. We examine the solutions to this equation by a combination of analytical and numerical methods and investigate its long-time limit. We study an important limit of this equation for small transaction sizes and derive a partial integrodifferential equation governing the evolution of the wealth distribution in a closed economy. We then describe how this model can be extended to include features such as inflation, production, and taxation. In particular, we show that the model with taxation exhibits the basic features of the Pareto law, namely, a lower cutoff to the wealth density at small values of wealth, and approximate power-law behavior at large values of wealth. © 2014 Published by the American Physical Society.
