The Convergence Of Multinational Standards And Practices In International Financial Reporting
The International Financial Reporting Standards (IFRS) is pending a move to incorporate a single set of accounting standards across International borders. The definitive decision for uniting the standards appears to be stalemated. The pending move by the United States to adopt financial reporting practices set forth by the IFRS to encompass a single set of reporting standards bears both advantages and disadvantages for multinational corporations. This paper examines some of the difficulties that can arise by using a single set of standards and addresses two significant studies regarding converging reporting standards. The paper concludes by discussing issues that could potentially arise if the standards are adopted in their entirety by the United States and the political issues that could emerge resultant of their adoption. The significance of international investment opportunities in foreign equity securities by investors in the United States and the significant number of foreign corporations registered on various securities exchanges around the world make the adoption and establishment of international reporting standards a challenge to many accounting professionals
The Impact Of Switching To International Financial Reporting Standards On United States Businesses
There has been controversy brewing among accounting professionals regarding the impact of switching to International Financial Reporting Standards (IFRS) on United States corporations as deemed to converge in the near future (Deming, 2005). The viewpoint presented in this paper is that the United States should conform to the international standards primarily because a single set of standards creates uniformity and comparability for stakeholders regardless of their geographic location. This paper addresses the potential advantages and disadvantages of moving to a global set of standards as well as how the Financial Accounting Standards Board (FASB) will need to work with the International Accounting Standards Board (IASB) to align the current United States Generally Accepted Accounting Principles (GAAP) with the newly proposed international accounting standards. If adopted, a wide range of issues relating to the operations within a business will need consideration in the future. One of these issues include effects of taxes as businesses will need to become keenly aware of how a country’s tax law and auditing practices affect their operations. The paper presents the repercussions United States corporations will face as a result of the convergence and how future accounting professionals, investors, financial institutions and students of accountancy. They will need to continue to stay abreast of changes in this area as these changes can ultimately change the way accounting standards are practiced, credentialed and taught over the next decade
DNAH6 and Its Interactions with PCD Genes in Heterotaxy and Primary Ciliary Dyskinesia.
Heterotaxy, a birth defect involving left-right patterning defects, and primary ciliary dyskinesia (PCD), a sinopulmonary disease with dyskinetic/immotile cilia in the airway are seemingly disparate diseases. However, they have an overlapping genetic etiology involving mutations in cilia genes, a reflection of the common requirement for motile cilia in left-right patterning and airway clearance. While PCD is a monogenic recessive disorder, heterotaxy has a more complex, largely non-monogenic etiology. In this study, we show mutations in the novel dynein gene DNAH6 can cause heterotaxy and ciliary dysfunction similar to PCD. We provide the first evidence that trans-heterozygous interactions between DNAH6 and other PCD genes potentially can cause heterotaxy. DNAH6 was initially identified as a candidate heterotaxy/PCD gene by filtering exome-sequencing data from 25 heterotaxy patients stratified by whether they have airway motile cilia defects. dnah6 morpholino knockdown in zebrafish disrupted motile cilia in Kupffer\u27s vesicle required for left-right patterning and caused heterotaxy with abnormal cardiac/gut looping. Similarly DNAH6 shRNA knockdown disrupted motile cilia in human and mouse respiratory epithelia. Notably a heterotaxy patient harboring heterozygous DNAH6 mutation was identified to also carry a rare heterozygous PCD-causing DNAI1 mutation, suggesting a DNAH6/DNAI1 trans-heterozygous interaction. Furthermore, sequencing of 149 additional heterotaxy patients showed 5 of 6 patients with heterozygous DNAH6 mutations also had heterozygous mutations in DNAH5 or other PCD genes. We functionally assayed for DNAH6/DNAH5 and DNAH6/DNAI1 trans-heterozygous interactions using subthreshold double-morpholino knockdown in zebrafish and showed this caused heterotaxy. Similarly, subthreshold siRNA knockdown of Dnah6 in heterozygous Dnah5 or Dnai1 mutant mouse respiratory epithelia disrupted motile cilia function. Together, these findings support an oligogenic disease model with broad relevance for further interrogating the genetic etiology of human ciliopathies

High Prevalence of Respiratory Ciliary Dysfunction in Congenital Heart Disease Patients With Heterotaxy
Patients with congenital heart disease (CHD) and heterotaxy show high postsurgical morbidity/mortality, with some developing respiratory complications. Although this finding is often attributed to the CHD, airway clearance and left-right patterning both require motile cilia function. Thus, airway ciliary dysfunction (CD) similar to that of primary ciliary dyskinesia (PCD) may contribute to increased respiratory complications in heterotaxy patients
Inscribed within the image: the visual character of early Christian mosaic inscriptions
Between the fourth and the seventh centuries CE, Christian patrons erected thousands of churches, chapels, and monasteries in cities and villages across the Mediterranean, decorating the apses, walls and floors of many of these structures with figural and geometric mosaics. These late antique Christian mosaics have been studied for their iconography, their Graeco-Roman components, and as evidence for the religious beliefs of newly-Christian patrons. However, art historians largely have ignored the ways that texts, inscribed within the visual field and composed of the same mosaic material, functioned as images in Christian spaces. For the first time, this thesis assembles the foundations of a comprehensive catalogue of early Christian mosaic inscriptions, places them back into the physical spaces in which they were meant to be read, and analyzes how these texts functioned both verbally and visually for the late antique reader/viewer, against the backdrop of Graeco-Roman traditions. I first examine the ekphrastic components of Christian inscriptions and look more closely at the different ways in which texts work with and against images and spaces, encouraging the viewer to react physically and mentally. Second, I study the language of light used by the inscriptions, and argue that this language linked text to the material of mosaic and enabled patrons to make complex statements about their cultural erudition and religious affiliation. Third, I investigate the functions and visual forms of short tituli which label scenes or name figures to simplify, authenticate or transform static images into narratives in motion. Finally, I turn to the frames of the inscriptions and contend that different forms conveyed powerful visual arguments. By writing these texts back into their mosaics, this thesis argues that texts and images were inseparable in the period, and that text written into images performed and played in more complex ways than has been previously thought. </p
