A Study about Social Inﬂuence Analysis in Large-scale Networks
Abstract:~ In large social networks, nodes (users, entities) are inﬂuenced by others for various reasons. For example, the colleagues have strong inﬂuence on one’s work, while the friends have strong inﬂuence on one’s daily life. How to differentiate the social inﬂuences from different angles(topics)? How to quantify the strength of those social inﬂuences? How to estimate the model on real large networks? To address these fundamental questions, we propose Topical Afﬁnity Propagation (TAP) to model the topic-level social inﬂuence on large networks. In particular, TAP can take results of any topic modeling and the existing network structure to perform topic-level inﬂuence propagation. With the help of the inﬂuence analysis, we present several important applications on real data sets such as 1) what are the representative nodes on a given topic? 2) how to identify the social inﬂuences of neighboring nodes on a particular node?
Introduction:~ Social network analysis often focus on macro-level models such as degree distributions, diameter, clustering coefﬁcient, communities, small world effect, preferential attachment, etc; work in this area includes. Recently, social inﬂuence study has started to attract more attention due to many important applications. However, most of the works on this area present qualitative ﬁndings about social inﬂuences[14, 16]. In this paper, we focus on measuring the strength of topic-level social inﬂuence quantitatively. With the proposed social inﬂuence analysis, many important questions can be answered such as 1) what are the representative nodes on a given topic? 2) how to identify topic-level experts and their social inﬂuence to a particular node? 3) how to quickly connect to a particular node through strong social ties?.

Case Studies about Innovative Domestic Credit Enhancement Entities and Techniques
Executive Summary: With decentralization, sub-sovereign governments are expected to take on increasing responsibilities in providing infrastructure services. The mobilization of local currency ﬁnancing to match local currency revenues is essential to develop sustainable infrastructure ﬁnance at the sub-sovereign level. This paper reviews innovative local credit enhancement entities and techniques that help mobilize domestic commercial debt resources for sub-sovereign infrastructure ﬁnance.
These credit enhancement schemes are provided either by a ﬁnancial entity or a program, and mitigate borrower credit risk and liquidity/market risk commonly observed in sub-sovereign lending in developing countries. (In these cases, ready-available borrower credit proﬁle and developed long-term debt markets often do not exist). Keep reading…
Case Study about Capacity Credit Algorithms for Intermittent Generators
Abstract: As the electric utility industry moves toward a new structure, the responsibility of providing a reliable portfolio of generating resources may be shifted among the various entities in the industry. To evaluate whether to undertake a construction project for new generating resources, utilities have traditionally used sophisticated models to assist in the comparison of alternative resources. It is not clear how this type of evaluation will be carried out after the restructuring dust has settled.
Introduction: Markets for electricity are undergoing rapid change. As these markets change, the traditional vertical integration of electric utilities may evolve into separate industries for electricity generation, transmission, and distribution. Although the precise form of these new industries is not known with any degree of certainty, it is clear that the generating industry will continue to evaluate whether to build new generators. The companies that will perform this type of analysis will probably be very diverse, and include very large generating companies that result from the many recent mergers, as well as smaller companies that are currently considered as independent power producers.
The need for major improvements in depression management has been well established. While most in the corporate world are aware of these deficiencies, the perception is that this fragmented system is difficult to change. PPG Industries, a medium-sized, Fortune 500 company manufacturing paints, stains, and sealants, has launched a successful and comprehensive program in the workplace that has improved outcomes for depressed employees.
The PPG approach is practical, addressing each step in the process one at a time. This process began by establishing a close working relationship between all entities responsible for employee health, many of which are currently carved out.
This enabled the company to have a comprehensive view of their depressed population and to examine their functional outcomes as well. To refer this case study click here Depression Management
Background: North America’s infrastructure is integral to our economic, environmental, and cultural vitality. Federal, state, and local entities have been successfully building and operating assets for generations. Across several sectors, our built assets are aging! Some roadway, water, and wastewater systems are more than 100 years old. To meet the renewal challenges and at the same time address the essential expansion and upgrade of our infrastructure, calls for exploring new processes, practices and skills crucial for the long-term sustainable management of assets..

Berkshire Hathaway (Berkshire), a conglomerate having roughly 80 subsidiaries as of March 2011, and, which generated superior returns for shareholders, is a prime example of such blue chip entities. Berkshire was equally known for the famed personality of its head, Warren Buffett (Buffett), who believed in a hands-off style of management and gave unfettered freedom to the heads of the subsidiaries to operate their respective businesses the way they wanted, subject to the conglomerate’s reputation not being compromised. Buffett’s laissez-faire approach could be gauged from the fact that the conglomerate whose turnover for financial year 2010 was around US $136 billion had, as of April 2011, just 21 employees at its head office to administer its 257,000 employees.
