Organizations are increasingly adopting digital strategies and investing heavily in digital technologies and initiatives. However, to date, there does not appear to be a clear understanding of digital strategies and their purpose, which forms the motivation for this research. This research-in-progress study aims to address this research gap by exploring 1) the various conceptions of digital str...

•Many parents use multiple monitoring strategies in different combinations over time to monitor their adolescents.•Adolescents of parents who use multiple strategies reported greater risk involvement.•Parents who solicited information only from adolescents had greater knowledge and adolescent disclosure.

Qualitative propagation influences in qualitative inferences are unlike and interrelated on the different hierarchy of knowledge granules, and quantitative information loss easily results in reasoning conflicts. This paper presents a hierarchical qualitative inference model with substructures which to some extent can eliminate the qualitative impact of uncertainty and solve trade-off problems b...

The focus of this paper is on developing ways to evaluate teaching performance on a regular basis as a means of improving teaching effectiveness and increasing student learning in the classroom. In particular, this paper shows how an instructor-developed pretest, when given at the start of an introductory economics course as part of a preand post-test strategy, can be used as a diagnostic and d...

We study observation-based strategies for partiallyobservable Markov decision processes (POMDPs) with omega-regular objectives. An observation-based strategy relies on partial information about the history of a play, namely, on the past sequence of observations. We consider the qualitative analysis problem: given a POMDP with an omega-regular objective, whether there is an observation-based str...

This paper presents a structured power and energy-flow-based qualitative modelling approach that is applicable to a variety of system types including electrical and fluid flow. The modelling is split into two parts. Power flow is a global phenomenon and is therefore naturally represented and analysed by a network comprised of the relevant structural elements from the components of a system. The...
