The social media space has evolved into a large labyrinth of information exchange platform and due to the growth in the adoption of different social media platforms, there has been an increasing wave of interests in sentiment analysis as a paradigm for the mining and analysis of users’ opinions and sentiments based on their posts. In this paper, we present a review of contextual sentiment analysis on social media entries with a specific focus on Twitter. The sentimental analysis consists of two broad approaches which are machine learning which uses classification techniques to classify text and is further categorized into supervised learning and unsupervised learning; and the lexicon-based approach which uses a dictionary without using any test or training data set, unlike the machine learning approach.

Advance in VLSI technology has led to the emergence of on-Chip Systems (SoC), where a complete system with a large number of intellectual property cores can be integrated onto a single silicon chip. The performance of SoCs highly depends on the speed and efficiency of their underlying communications subsystems. On-Chip Network (NoC), have been suggested to overcome the scalability problem found in traditional shared-bus communication architectures. Intensive research studies are conducted in an attempt to find the optimal networks in terms of performance and cost such as power consumption, and silicon area.

Introduction Technology (IT) has had a radical impact on business processes in both developed and developing countries. It facilitates the streamlining of the administrative process and enables the decentralisation of the scope and scale of the business. An Accounting Information System (AIS) is the system of records a business keeps maintaining its accounting system. This includes the purchase, sales, and other financial processes of the business. The purpose of AIS is to accumulate data and provide decision makers (investors, creditors, and managers) with information to make decisions. While this was previously a paper-based process, most modern businesses now use computerised accounting software such as Sage, Peachtree, Pegasus, Oracle Financial, Iris etc. These are referred to as Computerised Accounting Information System (CAIS). It should be noted that Computerised Accounting Information Systems (CAIS) and IT- based Accounting Systems mean one and the same thing. Both of these will be used interchangeably in this dissertation.

We present the business federation as a new organizational form using insights from business literature as means to tailor make services to clearly defined market segments. We illustrate how professional service firms can achieve eco- nomic growth through operating locally within an international network. Within the business federation local offices gain access to resources through an extreme form of delegation as it is not top management that delegates to local offices but rather local units that give top management the permission to handle certain tasks because it is most efficient this way. With these new realities existing strategies do not seem to provide the necessary cure. Firms must constantly innovate using insights from new organizational models.

Fraud is prevalent in society and is increasing considerably over in recent years. Auditors have been criticized severally because they tend to reach conclusion based upon inadequate audit processes, and hence, the validity of the audit conclusion has often been questioned. This study thus sought to identify the various types of fraud encountered during financial transactions, evaluate the adoption of Computer Aided Audit Tools (CAATs) in fraud detection in an organization, appraise the impact of CAATs on performance of an organization, and ascertain the problems of CAATs' application within an organization. Data for the study was collected using a well-structured questionnaire which was distributed among 250 employees of an auditing company. The data were analysed using descriptive statistics and SPSS package, and the hypothesis of the study was analysed using regression analysis. The findings of the study showed that 72.8 % of the respondents agreed that CAATs have played a major role in fraud detection, and hence can be used to curb fraud to a minimal level in organisations. It was also discovered that CAAT helped to improve the auditors' performance as corroborated by 58.1 % of the respondents. However, quiet a handful of respondents (23.0 %) were undecided in this respect as they claimed that the improved performance has been associated with much stress and pressure. Furthermore, the cost of implementing CAAT, the required skills to be acquired for its usage, and systems database requirements, were some of the problems found to be associated with the application of CAAT in organisations. © 2012 Springer Science+Business Media
