When estimating the power of genetic association studies, the allele and genotype frequencies are often assumed to be known, and the numbers of individuals with each genotype are set equal to their expectations under Hardy-Weinberg equilibrium. In fact, both allele and genotype frequencies are unknown and thus random. It has previously been suggested that ignoring uncertainty in these parameter...
Genetic association studies are a powerful tool to detect genetic variants that predispose to human disease. Once an associated variant is identified, investigators are also interested in estimating the effect of the identified variant on disease risk. Estimates of the genetic effect based on new association findings tend to be upwardly biased due to a phenomenon known as the "winner's curse." ...
This mini-corpus, cross-linguistic, comparative, and norm-referenced study intends to render the most frequently and oft-used affixes in the written descriptive tasks in the performance of English language materials developers (ELMDs) and Iranian English language undergraduates (IELUs). Samples of writings of both groups were studied and analyzed through affixation principles. The frequency of ...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
abstract purpose of this paper: this paper presents an analysis toward understanding the business value components that a health care organization can drive by adopting rfid technology into its system. this researcher proposes a framework for evaluating the business value of rfid technology. to do so, emphasis is put on delivering business value through refining business processes and expanding...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...

postcolonial feminism, also dubbed as third world feminism, is an innovative approach, demonstrating the way women of colonized countries suffer from both native patriarchies and imperial ideology. also due to this double-colonization, postcolonial feminists contend that third world women are subjected to both colonial domination of empire and male domination of patriarchy. while western femini...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
Guaranteed Annuity Options (GAOs) are options available to holders of certain pension policies. Under these contracts, policyholders contribute premiums into a fund managed by the insurer. At retirement, the policyholders buy life annuities at a guaranteed rate provided by the original insurer, or annuitize with another insurer. If the guaranteed annuity rates are better than the prevailing rat...
