The Impact

This chapter reviews the main types of access control mechanisms that can be used to govern subscription-based financial services. The overall performance of these mechanisms is analyzed with respect to several important features of subscription-based financial services. Namely, the chapter analyzes the impact of the following features: (1) the number of clients/ subscriptions can be potentially large; (2) the number and types of subscriptions offered by a provider varies in time; (3) subscription terms may change; and (4) subscriptions terms may take into account mutable information. Furthermore, the chapter presents in detail one mechanism that achieves good performance.

The Impact

Almost all computing systems and applications in organizations include some form of access control mechanisms. Managing secure access to computing resources is an important but a challenging task, requiring both administrative and technical measures. This study examines the influence of administrative access control measures on technical access control mechanisms. Based on the four access control clauses defined by ISO/IEC27002, this study develops a model to empirically test the impact of access control policies on systems and applications control activities. The study employs Partial Least Square Structural Equation Modelling (PLS-SEM) to analyze data collected from 223 samples through a survey questionnaire. The results show that the greatest significant impact on applications and systems access control measures is through access control policies mediated by users' responsibilities and accountability and user access management activities. But the direct impact of access control policies on applications and systems access control measures is not significant.

The Impact

The Indian mutual fund industry is one of the fastest growing and most competitive segments of the financial sector. The extent of under-penetration in the market is a sore point with the financial services industry, with a large amount of savings being channelized into fixed deposits, gold and real estate rather than the capital markets. The mutual fund industry is yet to spread its reach beyond Tier I cities. The top fifteen cities contribute to 85% of the pie, with the remaining 15% distributed among other cities. The study seeks to determine the impact of decision making of investors on current situation of mutual fund industry.

The Impact

This study evaluates the relevance of inclusive financial access in moderating the effect of income inequality on economic growth in 48 countries in Sub-Saharan Africa (SSA) for the period 1995 to 2017. The findings using the Generalised Method of Moments (sys-GMM) technique show that inclusive financial access contributes to reducing inequality in the short run, contrary to the Kuznets curve. The result reveals a negative effect of financial access on the relationship between income inequality and economic growth. There is a positive net effect of inclusive financial access in moderating the impact of income inequality on economic growth. Given the need to achieve the Sustainable Development Targets in the sub-region, policymakers and other stakeholders of the economy must design policies and programmes that would enhance access to financial services as an essential mechanism to reduce income disparity and enhance sustainable economic growth.

The Impact

Dataset size is considered a major concern in the medical domain, where lack of data is a common occurrence. This study aims to investigate the impact of dataset size on the overall performance of supervised classification models. We examined the performance of six widely-used models in the medical field, including support vector machine (SVM), neural networks (NN), C4.5 decision tree (DT), random forest (RF), adaboost (AB), and naïve Bayes (NB) on eighteen small medical UCI datasets. We further implemented three dataset size reduction scenarios on two large datasets and analyze the performance of the models when trained on each resulting dataset with respect to accuracy, precision, recall, f-score, specificity, and area under the ROC curve (AUC). Our results indicated that the overall performance of classifiers depend on how much a dataset represents the original distribution rather than its size. Moreover, we found that the most robust model for limited medical data is AB and NB, followed by SVM, and then RF and NN, while the least robust model is DT. Furthermore, an interesting observation is that a robust machine learning model to limited dataset does not necessary imply that it provides the best performance compared to other models.

Comprehensive Survey

Information-Centric Networking (ICN) has recently emerged as a prominent candidate for the Future Internet Architecture (FIA) that addresses existing issues with the host-centric communication model of the current TCP/IP-based Internet. Named Data Networking (NDN) is one of the most recent and active ICN architectures that provides a clean-slate approach for Internet communication. NDN provides intrinsic content security where security is directly provided to the content instead of communication channel. Among other security aspects, Access Control (AC) rules specify the privileges for the entities that can access the content. In TCP/IP-based AC systems, due to the client-server communication model, the servers control which client can access a particular content. In contrast, ICN-based networks use content names to drive communication and decouple the content from its original location. This phenomenon leads to the loss of control over the content, causing different challenges for the realization of efficient AC mechanisms. To date, considerable efforts have been made to develop various AC mechanisms in NDN. In this article, we provide a detailed and comprehensive survey of the AC mechanisms in NDN. We follow a holistic approach towards AC in NDN where we first summarize the ICN paradigm, describe the changes from channel-based security to content-based security, and highlight different cryptographic algorithms and security protocols in NDN. We then classify the existing AC mechanisms into two main categories: Encryption-based AC and Encryption-independent AC . Each category has different classes based on the working principle of AC (e.g., Attribute-based AC, Name-based AC, Identity-based AC). Finally, we present the lessons learned from the existing AC mechanisms and identify the challenges of NDN-based AC at large, highlighting future research directions for the community.

Threshold Point

This paper examines the effect of financial inclusion on the firm growth of the manufacturing sector (513 firms) in selected ASEAN countries (Malaysia, Philippines, and Vietnam) using a cross-section threshold estimation technique. The levels of financial inclusion across firms were measured based on the distribution of financial services (access to credit). The main findings revealed that there is a non-monotonic effect of financial inclusion on the firm’s growth. These findings show that the impact of financial inclusion on firm growth in the manufacturing sector is significantly positive below a threshold point, and turns to significantly negative after a certain threshold point has been reached. These new findings suggest that manufacturing firm owners and banking institutions should deepen their financial inclusion efforts, and limit the distribution of credit access within the optimum value or threshold level in promoting the growth of the firm.

The Impact

The authors examine the impact of the remote delivery of financial services on the branch network of British building societies. The current phase of branch-network rationalisation in the financial sector in Europe and North America is argued in the academic literature to be the inevitable consequence of the growth of electronic and telemediated forms of delivery of financial services. In the British building society sector, despite some evidence of branch closure as the use of the Internet and telephone call centres in the delivery of financial services has grown, the picture that emerges is of a dynamic branch network that is responding to changing customer demands and new technological possibilities. Face-to-face advice and discussions between customers and trained ‘experts’ remain an important part of the mortgage transaction. In the savings market, where products have become more commodified, telephone call centres and, more recently, the Internet have become more prominent, but institutions still rely heavily on the branch network to deliver services. The authors suggest that, although there have been changes in the relative importance of different distribution channels as sources of business in the financial sector, it is wrong to view these changes in terms of a simple branch-versus-direct dichotomy. A more complex picture is presented, with most institutions adopting a multichannel approach to the delivery of financial services, and electronic forms of delivery of financial services being developed as an additional delivery channel alongside the branch.
