THE REAL STEP IN CONVERGENCE PROJECT: A PARADIGM SHIFT FROM REVENUE RECOGNITION TO REVENUE FROM CONTRACTS WITH CUSTOMERS

Revenue is a crucial number to users of financial statements in assessing an entity’s financial performance and position. In May 2014, the IASB and FASB published a new joint standard (IFRS 15 vs. ASC 606) on revenue recognition which replaces most of the detailed guidance on revenue recognition that currently exists under US GAAP and IFRS. The new rules will apply to all entities that enter into contracts with customers. Coming up with a joint standard about recognizing revenue is a major achievement for the standard setters, but for corporate world the real work is fast approaching. According to first introduction paragraph of the standard IFRS 15 establishes principles for reporting useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. Adoption of the joint standard on revenue recognition will represent a major advancement toward the ultimate goal of creating one set of high quality international accounting standards. The purpose of this study is two-fold: first to highlight the history and background of the new standard; second to make some policy recommendations for companies towards preparation for new standard

On the Communication Cost of MDS Erasure Codes in Distributed Storage Systems

Distributed storage systems store some redundant data to keep the degree of availability of the stored data constant and also to increase the system's resistance against failures. This type of systems usually use pure replication or methods based on RAID systems as redundancy schemes. In this paper, we study the communication cost of a distributed data storage system using Maximum Distance Separable (MDS) erasure codes. Our focus is reduction of the cost of one-to-many communication used in data reconstruction/repair initialization and update operations. We propose the use of two different communication approaches on the area of distributed storage systems for the above operations; Steiner tree approach and multi-shortest path approach. We also analyse these two communication approaches empirically and theoretically. Our theoretical results indicate that Steiner tree approach has lower message usage, whereas, multi-shortest path approach has lower time usage for data reconstruction/repair initialization operations. On the other hand, Steiner tree approach has better message and time metrics for the data update process. Furthermore, our experimental results support these theoretical results. Thus, users can choose between the two approaches depending on their needs and priorities

Re-framing Inclusive Education Through the Capability Approach: An Elaboration of the Model of Relational Inclusion

Scholars have called for the articulation of new frameworks in special education that are responsive to culture and context and that address the limitations of medical and social models of disability. In this article, we advance a theoretical and practical framework for inclusive education based on the integration of a model of relational inclusion with Amartya SenΓÇÖs (1985) Capability Approach. This integrated framework engages children, educators, and families in principled practices that acknowledge differences, rather than deficits, and enable attention to enhancing the capabilities of children with disabilities in inclusive educational environments. Implications include the development of policy that clarifies the process required to negotiate capabilities and valued functionings and the types of resources required to permit children, educators, and families to create relationally inclusive environments

Two-year clinical evaluation of three adhesive systems in non-carious cervical lesions

OBJECTIVES: Adhesive systems are continuously being introduced to Dentistry, unfortunately often without sufficient clinical validation. The aim of this study was to evaluate the clinical performance of cervical restorations done with three different adhesive systems. MATERIAL AND METHODS: 158 non-carious cervical lesions of 23 patients were restored with a nanofilled composite resin (Filtek Supreme, 3M/ESPE) combined with Single Bond (3M/ESPE, group SI), Clearfil SE (Kuraray Medical Inc., group CL) and Xeno III (De Trey Dentsply, group XE). In groups SI-B, CL-B and XE-B, the outer surface of the sclerotic dentin was removed by roughening with a diamond bur before application of the respective adhesive systems. In groups CL-BP and XE-BP, after removal of the outer surface of the sclerotic dentin with the bur, the remaining dentin was etched with 37% phosphoric acid and the self-etch adhesive systems Clearfil SE and Xeno III were applied, respectively. Lesions were evaluated at baseline, and restorations after 3 months, 1 year and 2 years using modified USPHS criteria. RESULTS: After 2 years, no significant difference was found between the retention rates of the groups (p >0.05). Although groups CL and SI showed significantly better marginal adaptation than group XE (

Numerical modeling of groundwater flow based on explicit and fully implicit schemes of finite volume method

This paper documents a novel numerical model for calculating the behavior of unsteady, one-dimensional groundwater flow by using the finite volume method. The developed model determined water table fluctuations for different scenarios as follows: Drainage and recession from an unconfined aquifer, and water table fluctuations above an inclined leaky layer due to ditch recharge with a constant and variable upper boundary condition. The Boussinesq equation, which is the governing equation in this domain, is linearized and solved numerically in both of the explicit and fully implicit conditions. Meanwhile, the upwind scheme is employed to discretize the governing equation. The computed outcomes of both the explicit and implicit approaches agreed well with the results of analytical solution and laboratory experiments. The main reason is that in the first half of simulation process explicit scheme obtains slightly better results and in the second half of the simulation process fully implicit scheme predicts more reliable outcomes that are hidden in the neighbor node points. As a final point, the numerical outcomes confirm that the developed model is capable of calculating satisfactory outcomes in engineering and science applications
