Thanks to the explosion of the wireless technology, mobile environments are becoming the leading software platforms for extracting knowledge and interacting with enterprise information systems. Data and services availability at all times is the major benefit coming from such deployment scenario, but new research challenges pose serious limitations concerning data engineering issues. In fact, although if one can suppose that re-writing and re-adapting data structures, algorithms, and data reliability/dependability schemes is the natural way to support efficient data management on mobile environments, new issues and old limitations arise, particularly for what concerns with data availability and consistency in wireless network environments.

With the rise of social networking approach, there has been a surge of users generated content all over the world and with that in an era where technology advancement are up to the level where it could put us in a step ahead of pathogens and germination of diseases, we couldn’t help but to take advantage of that advancement and provide an early precaution measures to overcome it. Twitter on the other hand are one of the social media platform that provides access towards a huge data availability. To manipulate those data and transform it into an important information that could be used in many different scope that could help improve people’s life for the better. In this paper, we gather all algorithm that are available inside Meta Classifier to compare between them on which algorithm suited the most with the dengue fever dataset. This research are using WEKA as the data mining tool for data analyzation.

ABSTRACT This paper examines the administrative and accounting reforms coordinated by Herman A. Metz around the turn of the 20th century in New York City. Reform efforts were motivated by deficiencies in administering New York City's finances, including a lack of internal control over monetary resources and operational activities, and opaque financial reports. The activities of Comptroller Metz, who collaborated with institutions such as the New York Bureau of Municipal Research, were paramount in initiating and implementing the administrative and accounting reforms in the city, which contributed to reform efforts across the country. Metz promoted the adoption of functional cost classifications for city departments, developed flowcharts for improved transaction processing, strengthened internal controls, and published the 1909 Manual of Accounting and Business Procedure of the City of New York, which laid the groundwork for transparent financial reports capable of providing vital information about the city's activities and subsidiary units.

SYNOPSIS We examine whether regulations requiring accelerated filing deadlines and internal control reporting and testing affect financial statement reliability. Unlike prior research, we examine whether these regulatory changes are associated with an increase in the likelihood that misstatements originate in the period following the respective change. If the implementation of these rules causes a misstatement, then the misstatement would most likely occur in the period immediately following the rule change. We provide evidence that accelerated filers (AFs) experience an increase in the likelihood of an originating misstatement following the acceleration of filing deadlines from 90 to 75 days. Large accelerated filers (LAFs), however, do not experience a similar increase following this acceleration or the subsequent acceleration from 75 to 60 days. After the implementation of the SOX Section 404 internal control requirements, we find that the likelihood of an originating misstatement declined for AFs but not for LAFs. Taken together, the findings suggest that, although AFs experienced an initial decrease in financial statement reliability, this decrease was temporary.

SYNOPSIS We investigate the effect of mandatory International Financial Reporting Standards (IFRS) adoption in the European Union on the association between accounting estimates and future cash flows, a key concept of accounting quality within the International Accounting Standard Board conceptual framework. We find that the predictive value of accounting estimates improves after IFRS adoption. This improvement is largely driven by specific types of accounting estimates, such as accounts receivable, depreciation, and amortization expense. We also find that the improvement is concentrated in countries with larger differences between pre-IFRS domestic GAAP and IFRS. Our findings suggest that IFRS allow managers to exercise their judgment to provide information about future cash flows through the more subjective/judgmental portion of accounting accruals. JEL Classifications: M16; M49; O52. Data Availability: The data used in this study are from public sources identified in the study.
