Recent exploratory efforts in discourse-level language modeling have relied heavily on calculating Pointwise Mutual Information (PMI), which involves significant computation when done over large collections. Prior work has required aggressive pruning or independence assumptions to compute scores on large collections. We show the method of Conditional Random Sampling, thus far an underutilized t...

Statistical graphics play a crucial role in exploratory data analysis, model checking and diagnosis. Until recently there were no formal visual methods in place for determining statistical significance of findings. This changed, when Buja et al. [2009] conceptually introduced two protocols for formal tests of visual findings. In this paper we take this a step further by comparing the lineup pro...

Science policy is increasingly shifting towards an emphasis in societal problems or grand challenges. As a result, new evaluative tools are needed to help assess not only the knowledge production side of research programmes or organisations, but also the articulation of research agendas with societal needs. In this paper, we present an exploratory investigation of science supply and societal ne...

As more and more companies are deploying, or plan to deploy, information systems, the organizational capabilities to effectively deploy information technologies to support and shape businesses become increasingly important. While many studies have focused on how to acquire state-of-the-art information technologies and on how to effectively utilize implemented information technologies, more stud...

Elicitation of business process knowledge can be facilitated by conceptual models of collaborative work. Models of collaborative business processes with actors participating in different roles are complex constructs with flows of individual activities that are coupled via acts of communication. The process of elicitation in such cases can benefit from separating the modeling process for each ro...

This paper focus on the environmental disclosure (ED) promoted by firms, due to the strong demand for information and identification of the relevant data that pursuit the new legal requirements. The methodology is separate, by one side, on the theoretical framework based on the disclosure of environmental information (EI) and the true and fair view based on the accounting perspective. Indeed, t...

This research presents the exploratory application of behavioural threshold theory on group behaviour related to information security. Behavioural threshold analysis is presented as a possible tool for aiding the development of security awareness programs. Generic behavioural threshold analysis is presented and then applied in the domain of information security by collecting data on the behavio...

Theoretical models of collaborative learning through online discussions presuppose that students generally attend to others’ posts. However, a succession of studies over the last decade has shown this assumption to be unwarranted. Instead, research indicates that learners attend to others’ posts in diverse and particular ways—an activity we have conceptualized as online “listening.” In this stu...

The main thesis of the paper is that in the case of modern statistics, the differences between the various concepts of models were the key to its formative controversies. The mathematical theory of statistical inference was mainly developed by Ronald A. Fisher, Jerzy Neyman, and Egon S. Pearson. Fisher on the one side and Neyman–Pearson on the other were involved often in a polemic controversy....
