This paper aims to build a novel model and approach that assist an aircraft MRO procurement and overhaul management problems from the perspective of aircraft maintenance service provider, in order to ensure its smoothness maintenance activities implementation. The mathematical model utilizes the data related to warehouse inventory management, incoming customer service planning as well as risk forecast and control management at the decision-making stage, which facilitates to alleviate the negative impact of the uncertain maintenance demands on the MRO spare parts inventory management operations.

A stochastic model is proposed to formulate the problem to minimize the impact of uncertain maintenance demands, which provides flexible procurement and overhaul strategies. A Benders decomposition algorithm is proposed to solve large-scale problem instances given the structure of the mathematical model.

Compared with the default branch-and-bound algorithm, the computational results suggest that the proposed Benders decomposition algorithm increases convergence speed.

The results among the same group of problem instances suggest the robustness of Benders decomposition in tackling instances with different number of stochastic scenarios involved.

Extending the proposed model and algorithm to a decision support system is possible, which utilizes the databases from enterprise's service planning and management information systems.

A novel decision-making model for the integrated rotable and expendable MRO spare parts planning problem under uncertain environment is developed, which is formulated as a two-stage stochastic programming model.

In this chapter, we apply the new measure of speculative activities (hereafter, named the speculative ratio) in Chan, Nguyen, and Chan (2013) to study the relationship between those activities and volatility in the oil futures market. We document that the speculative ratio (trading volume divided by open interest) can isolate speculative elements from total trading activities. Using the oil futures data and dividing the data into two subperiods surrounding Hurricane Katrina, we find an increased speculative trades in the post-Hurricane Katrina period. Our results show that speculative activities create a more volatile oil futures market and they lower the information flow between volatility and speculative activities in the post-Hurricane Katrina period.

As background information, the authors describe the Service Leadership Initiative (SLI), which provided pump-priming funding for government-funded universities in Hong Kong to develop educational programmes preparing students to become service leaders. The universities were expected to create opportunities for students to develop requisite task competencies, character strengths and caring dispositions through experiential learning. The authors also describe how, prior to the SLI, Lingnan University (LU) had already been building networks and systems for service-learning projects to benefit the community while furthering academic development, and this platform was helpful for service leadership development.

In the core of this chapter, the authors explain how faculty and staff members at LU have designed, structured and supported course embedded service-learning projects that were undertaken by teams of undergraduate students as vehicles for developing their attributes as emerging service leaders.

Based on our prior research into students’ accounts of negative and positive experiences, the authors identify and explain some unfavourable and favourable contextual factors for undergraduates’ development as emerging service leaders. The favourable factors are based on three preconditions: genuine service leadership responsibilities; community partner representatives as co-educators; and the students’ own readiness to practice as service leaders (as opposed to learning passively).

Based on students’ descriptions, the authors provide illustrations of how students practiced ten service leadership attributes in the context of service-learning projects conducted at local kindergartens, and about the further self-developmental needs they identified. This chapter concludes with the observation that the discrete service leadership attributes the authors identified appear in practice to be mutually supporting.

With the rapid development of social media, many organizations have begun to attach importance to social media platforms. This research studies the management and the use of social media in academic music libraries, taking the Center for Chinese Music Studies of the Chinese University of Hong Kong (CCMS) as a case study.

We conducted a sentiment analysis of posts on Facebook’s public page to analyze the reaction to the posts with some exploratory analysis, including the communication trend and relevant factors that affect user interaction.

Our results show that the Facebook channel for the library has a good publicity effect and active interaction, but the number of posts and interactions has a downward trend. Therefore, the library needs to pay more attention to the management of the Facebook channel and take adequate measures to improve the quality of posts to increase interaction.

Few studies have analyzed existing data directly collected from social media by programming based on sentiment analysis and natural language processing technology to explore potential methods to promote music libraries, especially in East Asia, and about traditional music.

Researchers have discovered that service learning affects students’ academic, personal, and social development. However, currently there is a gap in literature analyzing ways in which service learning affects students’ perceived leadership skills. This study examined the effectiveness of service learning on the perceived leadership skills of 74 sport management undergraduate students at a mid-sized, Midwestern, public university using Kouzes’ and Posner’s Student Leadership Practices Inventory instrument, which examines leadership practices in five areas: Model the Way, Inspire a Shared Vision, Challenge the Process, Enable Others to Act, and Encourage the Heart. The results of this study may help faculty members and administrators to better understand the potential of utilizing service learning projects in their classrooms as a vehicle for their students to develop quality leadership practices. Recommendations for further research and practice are also discussed.

Jobs fundamentally influence and are influenced by individuals, organizations, and societies. However, jobs themselves are largely conceptualized in an atomized and disembodied way. They are understood as being designed, altered, and dissolved and bringing their consequences one at a time. I advance an alternative view of jobs as a system of ties that span jobs, organizations, and the environment beyond organizational boundaries. These ties create Gordian Knots that hold jobs in place and explain how they change. I illustrate the model with case study evidence and propose an agenda for research on jobs as organizational systems.

This research reviews numerous studies of the relationship between consumer knowledge and external search in conventional marketing channels to investigate differences among these studies that have produced conflicting results. The findings provide a benchmark for future researchers and practitioners seeking to gain insight into consumer information search processes unfolding in the new environment of online, mobile, and social networking channels.

A meta-analysis of an extensive array of empirical studies of the relationship between consumer knowledge and external information search was conducted. Regression analysis was used to test whether certain characteristics in the studies can explain variability in the effect sizes in which effect sizes are entered as dependent variables and moderators as independent variables.

Objective and subjective knowledge tend to increase search, while direct experience tends to reduce search. Consumers with higher objective knowledge search more when pursuing credence products. However, they search relatively less when pursuing search products. Consumers with higher subjective knowledge are much more likely to search in the context of experience products, but as is the case for objective knowledge having little effect on search for experience products, subjective knowledge has no significant effect on information seeking for search products. In addition, objective knowledge facilitates more information search in a complex decision-making context while higher subjective knowledge fosters more external information search in a simple decision-marketing context. Finally, the findings indicate that the knowledge search relationship reflects strong linkage in the pre-Internet era.

Relatively little is known about how the relationship between knowledge and information search varies across different types of products in simple or complex decision-making contexts. This study begins to fill this gap by providing insight into the relative importance of objective knowledge, subjective knowledge, and direct experience in influencing consumer information search activities for search, experience, and credence products in simple or complex decision-making contexts.

Sociologists have long thought of the integration of people in communities – social integration – and hierarchical social systems – systemic integration – as contradictory goals. What strategies allow organizations to reconcile social and systemic integration? We examine this question through 40 in-depth, longitudinal interviews with leaders of nonprofit organizations that engage in the dual pursuit of social and systemic integration. Two processes reveal how the internal structure of organizations often mirrors the ways in which organizations are embedded in their local environments. When organizations engage in loose demographic coupling, relegating those who “match” the community to the work of social integration, they produce internal inequalities and justify them by claiming community building as sacred work. When engaging in community anchoring, organizations challenge internal and external inequalities simultaneously, but this process comes with costs. Our findings contribute to a constructivist understanding of community, the mechanisms by which organizations produce inequalities, and a place-based conception of organizations as embedded in community.
