RESEARCH: A Revised Religious Fundamentalism Scale: The Short and Sweet of It

Abstract: Despite its relatively good psychometric properties and empirical validity, the 20-item Religious Fundamentalism scale developed by the authors has several problems. It does not measure all of the aspects of fundamentalism, as defined, as well as it might. And it could stand to be shorter. An item development program led to a 12-statement revision that is more internally consistent despite having broader coverage. As well, it is as reliable as the longer original scale, despite being 40% shorter, and at least as empirically valid.

Spread of a Novel Influenza A (H1N1) Virus via Global Airline Transportation

Abstract: International air travelers departing from Mexico in March and April 2009 were unknowingly transporting a novel influenza A (H1N1) virus around the world. The purpose of this analysis was to show h...

Interference management in OFDMA femtocell networks: issues and approaches

Abstract: One of the effective techniques of improving the coverage and enhancing the capacity and data rate in cellular wireless networks is to reduce the cell size (i.e., cell splitting) and transmission distances. Therefore, the concept of deploying femtocells over macrocell has recently attracted growing interests in academia, industry, and standardization forums. Various technical challenges towards mass deployment of femtocells have been addressed in recent literature. Interference mitigation between neighboring femtocells and between the femtocell and macrocell is considered to be one of the major challenges in femtocell networks because femtocells share the same licensed frequency spectrum with macrocell. Further, the conventional radio resource management techniques for hierarchical cellular system is not suitable for femtocell networks since the positions of the femtocells are random depending on the users' service requirement. In this article, we provide a survey of the different state-of-the-art approaches for interference and resource management in orthogonal frequency-division multiple access (OFDMA)-based femtocell networks. A qualitative comparison among the different approaches is provided. To this end, open challenges in designing interference management schemes for OFDMA femtocell networks are discussed.

Adriamycin-induced heart failure: mechanism and modulation.

Abstract: Adriamycin (doxorubicin) is one of the most effective chemotherapeutic agents against a variety of cancers, but its usefulness is seriously curtailed by the risk of developing heart failure. Available laboratory evidence suggests that an increase in oxidative stress, brought about by increased free radical production and decreased myocardial endogenous antioxidants, plays an important role in the pathogenesis of heart failure. Adriamycin-induced apoptosis and hyperlipidemia may also be involved in the process. Probucol, a lipid-lowering drug and an antioxidant, completely prevents the occurrence of heart failure by reducing oxidative stress as well as by the modulation of apoptis and high lipid concentrations. Thus, combined therapy with adriamycin and probucol has a high potential for optimizing the treatment of cancer patients.
