A people-to-people matching system using graph mining techniques

A people-to-people matching system (or a match-making system) refers to a system in which users join with the objective of meeting other users with the common need. Some real-world examples of these systems are employer-employee (in job search networks), mentor-student (in university social networks), consume-to-consumer (in marketplaces) and male-female (in an online dating network). The network underlying in these systems consists of two groups of users, and the relationships between users need to be captured for developing an efficient match-making system. Most of the existing studies utilize information either about each of the users in isolation or their interaction separately, and develop recommender systems using the one form of information only. It is imperative to understand the linkages among the users in the network and use them in developing a match-making system. This study utilizes several social network analysis methods such as graph theory, small world phenomenon, centrality analysis, density analysis to gain insight into the entities and their relationships present in this network. This paper also proposes a new type of graph called “attributed bipartite graph”. By using these analyses and the proposed type of graph, an efficient hybrid recommender system is developed which generates recommendation for new users as well as shows improvement in accuracy over the baseline methods.

A business engineering approach to client relationship management in a knowledge based firm

This thesis examines Customer Relationship Management and how the capabilities of an organisation to innovate can be enhanced via its implementation in a Knowledge Based Firm. The research identifies current customer knowledge components within an organisation and identifies for future use, CRM components for implementation within a Knowledge Based Firm. Opinions from a panel of experts' are identified for best practice customer relationship strategy, the most important CRM processes and identification of customer knowledge components that will form the basis of implementing a successful CRM to gain a competitive advantage through enhancing the innovative capability for a Knowledge Based Firm.

Capturing opportunities for business and innovation in knowledge intensive services

Research on opportunity has been extensively studied in contexts of new firm or new venture creation (Choi & Shepherd, 2004; Mullins & Forlani, 2005; Ozgen & Baron, 2007) where start-ups and new ventures use both opportunity discovery and opportunity creation (Alvarez & Barney 2005, 2007). Less research is found on examining the relationship between opportunity and innovation in existing firms (with Drucker (1985) an exception). In large firms, opportunity recognition has been analysed in terms of antecedent conditions, elements and outcomes (Ireland, Covin & Kuratko, 2009), but to date less attention has been given to how small and medium enterprises capture and use opportunities to remain competitive. Little research has been carried out regarding how smaller firms use opportunities to create new business with existing customers or use technological advances with new customers to create new economic activity, growth and competitive advantage. This study presents findings from a comparative case analysis of 20 diverse firms in the spatial information industry and identifies constructs associated with identifying opportunities that lead to better business performance and firm level innovation.

Contracts

Contracting essentially involves an agreement between two parties in relation to a particular matter. When defined in this way, contracting has been occurring as a social practice since humans first bartered and conducted trade, and should be understood as both an economic as well as a social transaction. This entry explains key aspects of the sociology While contracting is commonly understood to be a market based transaction, Polyani famously argued that for most of recorded history commercial transactions were in fact secondary to social relationships. In other words, whenever economic transactions occurred, they were always in the context of reciprocal social relationships. Historically the primary mode of exchange may well have been based on social exchange and reciprocity, however with the rise of extensive industrialization in the 18th Century, the primary mode of exchange has led to more of a market based mode of exchange in developed countries, with the focus more about the economic transaction. As an agreement between two entities, contracting is an essential element to economic systems as it is the basis of most transactions, whether the agreement is verbal or written, explicit or implied. Contracting is thus a pervasive activity in our society, particularly between organizations, although individuals also engage in contracting. Typically, when discussing contracting, authors have either focused on the nature of the agreement itself, or on the governance arrangements in place to carry out the agreement.

Does project culture matter? A comparative study of two major hospital projects

Purpose - Cultural issues in the construction industry have attracted growing attention from both practitioners and academia. However, there are few studies on culture issues at the project level. The influence of project culture has not traditionally been on the research radar. This research aims to investigate the impacts of project culture on the performance of construction projects. Design/methodology/approach - A case study approach, utilising questionnaire surveys, in-depth interviews and review of project documents, was employed to investigate project culture and its associated impacts in two major hospital projects. Findings - The results indicated that project culture played an important role in achieving harmonious relationships between project participants and better project outcomes in terms of schedule, functionality, satisfaction with the process, satisfaction with the relationships, environmental issues addressed commercial success, further business opportunities and overall performance. Case 1 outperformed Case 2 in these performance indicators. Similarly, it became clear that the project’s culture should be developed from the outset and sustained during the project period. Furthermore, it was also highlighted that the project culture should be translated to all levels of the supply chain i.e. sub-contractors and suppliers. Practical implications – The findings enabled the client to understand the role of project culture and actively commit towards the development and maintenance of the project culture from very early on. It also helps project teams to understand how to deal with cultural issues at the project level. Originality/value- This study is one of limited empirical studies that offer in-depth insights of how project culture affects the performance of construction projects. It is also the first study of hospital projects on the research topic.

A case study analysis of Israeli Organised Crime (IOC) (1990-2005) : applying the Crime Business Analysis Matrix (CBAM)

Israeli Organised Crime (IOC) gained prominence in the 1990s for its involvement in the manufacturing and wholesale distribution of MDMA through traditional trafficking networks across Europe. Equipped with astute business acumen and an entrepreneurial spirit, IOC dominated MDMA trafficking in Europe for more than a decade and remains as a major participant in this drug market. The paper analyses the entrepreneurial activities of IOC within the context of the MDMA market in Europe between 1990 and 2005 using the Crime Business Analysis Matrix (CBAM) as proffered by Dean, et al (2010). The study is in two parts. Part A provides a review of the literature as it pertains to IOC and its involvement in the European drug market, while Part B provides a qualitative analysis of their criminal business practices and entrepreneurialism of IOC within this context.
