Using mobile apps typically requires the disclosure of location data, which often accompanies requests for various other forms of private information. Existing research on information privacy has implied that consumers are willing to accept privacy risks for relatively negligible benefits, and the offerings of mobile apps based on location-based services (LBS) appear to be no different. However, until now, researchers have struggled to replicate realistic privacy risks within experimental methodologies designed to manipulate independent variables. Moreover, minimal research has successfully captured actual information disclosure over mobile devices based on realistic risk perceptions. The purpose of this study is to propose and test a more realistic experimental methodology designed to replicate real perceptions of privacy risk and capture the effects of actual information disclosure decisions. As with prior research, this study employs a theoretical lens based on privacy calculus. However, we draw more detailed and valid conclusions due to our use of improved methodological rigor. We report the results of a controlled experiment involving consumers (n=1025) in a range of ages, levels of education, and employment experience. Based on our methodology, we find that only a weak, albeit significant, relationship exists between information disclosure intentions and actual disclosure. In addition, this relationship is heavily moderated by the consumer practice of disclosing false data. We conclude by discussing the contributions of our methodology and the possibilities for extending it for additional mobile privacy research.

Defining a standard repeatable process for such staffing decisions requires a consistent classification scheme for the KSA-Ps, which this paper develops

We examine the productivity of two -person teams tasked to work independently on module construction versus two-person teams tasked to work concurrently on module construction. Analysis of this comparison reveals that teams in which member work more independently are significantly more productive than tightly coupled teams. Pair programming and lightweight software processes need to incorporate approaches designed to counteract this phenomenon.

The authors conclude that the role-based coordination protocol associated with agile software methodologies overcomes a significant productivity loss otherwise associated with concurrent software development pairs.

But governance research also finds that the knowledge of both parties must be incorporated in order to maximize decision effectiveness. The goal difference is resolved through governance forms that assign different decisions to the procurer and the provider. But this splitting of decision rights can impact how knowledge is shared. At the same time, unified teams are also capable of completing effective development projects as witnessed by the successes of agile development methodologies. These teams do not split decision rights and knowledge is more readily shared. Successful projects under one governance model may be identifiably different from successful projects under the other. This study extends governance research by understanding development project characteristics that indicate whether splitting decision rights...

However, we feel that for component engineering to be successful in fully exploiting reuse opportunities, components must be independent of the processes used to derive them. That is, there should be standard canonical forms for software artifacts that do not carry with them the baggage associated with a particular development methodology or process. This is the type of effort associated with the rapidly emerging discipline of software architecture, and would make the notion of "software component" much more like the analogous "hardware component" concept from hardware engineering. In this paper, we outline some initial modest ideas with regard to capturing a process-independent notion of a component "test case." Ultimately, the idea behind this work is to produce a complete conceptual framework for unders...

These networks support healthy brain function and are perturbed in a number of neurological disorders (e.g. schizophrenia). Their study is therefore an important and evolving focus for neuroscience research. The majority of network studies are conducted using functional magnetic resonance imaging (fMRI) which relies on changes in blood oxygenation induced by neural activity. However recently, a small number of studies have begun to elucidate the electrical origin of fMRI networks by searching for correlations between neural oscillatory signals from spatially separate brain areas in magnetoencephalography (MEG) data. Here we advance this research area. We introduce two methodological extensions to previous independent component analysis (ICA) approaches to MEG network characterisation: 1) we show how to derive pan-spectral networks that combine independent components computed within individual frequency bands. 2) We show how to measure the temporal evolution of each network with millisecond temporal resolution. We apply our approach to ~10h of MEG data recorded in 28 experimental sessions during 3 separate cognitive tasks showing that a number of networks could be identified and were robust across time, task, subject and recording session. Further, we show that neural oscillations in those networks are modulated by memory load, and task relevance. This study furthers recent findings on electrodynamic brain networks and paves the way for future clinical studies in patients in which abnormal connectivity is thought to underlie core symptoms.
