In Service For Sharing: Leadership And Leader - Follower Relationship Factors As Influencers Of Tacit Knowledge Sharing In The It Industry, Billy Whisnant, Odai Khasawneh

Odai Khasawneh

Tacit knowledge is an organizational resource that is difficult to cultivate. It requires that responsible agents in the organization take an active role in encouraging trust and the development of relationships where individuals feel that their voice will be heard and that there will be a benefit from them passing knowledge onto someone else. In knowledge work tacit knowledge is especially important. 

This research found that servant leadership is an important factor in influencing tacit knowledge sharing, however leader-member exchange is a factor that will strongly support the sharing of tacit knowledge. 

If there is a dearth in servant leadership, …

An Outlier Robust Block Bootstrap For Small Area Estimation, Payam Mokhtarian, Ray Chambers Mar 2014

An Outlier Robust Block Bootstrap For Small Area Estimation, Payam Mokhtarian, Ray Chambers

Payam Mokhtarian

Small area inference based on mixed models, i.e. models that contain both fixed and random effects, are the industry standard for this field, allowing between area heterogeneity to be represented by random area effects. Use of the linear mixed model is ubiquitous in this context, with maximum likelihood, or its close relative, REML, the standard method for estimating the parameters of this model. These parameter estimates, and in particular the resulting predicted values of the random area effects, are then used to construct empirical best linear unbiased predictors (EBLUPs) of the unknown small area means. It is now well known …

A General Framework For Infrastructure System Reliability Modelling And Analysis, Payam Mokhtarian, Mohammad-Reza Namazi-Rad, Tin Kin Ho, Mahmoud Efatmaneshnik Mar 2014

A General Framework For Infrastructure System Reliability Modelling And Analysis, Payam Mokhtarian, Mohammad-Reza Namazi-Rad, Tin Kin Ho, Mahmoud Efatmaneshnik

An infrastructure system is inherently complex, with layers of both explicitly defined and hidden or subtle interfaces with other infrastructure systems and human users. High availability is desired, which implies stringent requirements on reliability and safety. Reliability analysis typically starts at component or sub-system level and aggregates through the system functional hierarchy. Because of the system complexity, incorporating occurrences of all possible interactions and scenarios is not always practical and failure data is often limited. Moreover, there are unobserved events among the sub-systems distributing either randomly or with temporal trend. To facilitate reliability analysis amid the complex environment and uncertain …
