How to Achieve Effectiveness in Project Portfolio Management
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To promote a better understanding of the effectiveness in project portfolio management (PPM), this article investigates how PPM effectiveness can be achieved. Conducting case study research with four market-leading organizations in USA, the results reveal different...

Rethinking Why and How Organizations Acquire Information Technologies, Part 1: Conventional Explanations and Their Limits
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The purpose of this essay is to examine how a comfortable paradigm for explaining the spread of a major technology began cracking, shaken by new findings. I do this by, first, summarizing familiar explanations for the diffusion of computing, as much recently historical research still...

Rethinking Why and How Organizations Acquire Information Technologies, Part 2: Towards A New Understanding
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The purpose of this essay is to examine how a comfortable paradigm for explaining the spread of a major technology began cracking, shaken by new findings. I do this by, first, summarizing familiar explanations for the diffusion of computing, as much recently historical research still...

Secondary Low-Voltage Circuit Models - How Good is Good Enough?
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Utility power distribution system analysis has traditionally been performed considering only the primary, or medium-voltage (MV), system. Distributed energy resources are increasingly being located on the secondary, or low-voltage, side of the distribution transformer, requiring the...

Saliency in VR: How do people explore virtual environments?
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Understanding how people explore immersive virtual environments is crucial for many applications, such as designing virtual reality (VR) content, developing new compression algorithms, or learning computational models of saliency or visual attention. Whereas a body of recent work has focused...

How are muscle synergies affected by electromyography pre-processing?
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Muscle synergies have been used for decades to explain a variety of motor behaviors, both in humans and animals and, more recently, to steer rehabilitation strategies. However, many sources of variability such as factorization algorithms, criteria for dimensionality reduction...

A Vademecum on Blockchain Technologies: When, Which and How
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Blockchain is a technology making the shared registry concept from distributed systems a reality for a number of application domains, from the cryptocurrency one to potentially any industrial system requiring decentralized, robust, trusted and automated decision making in a...

How Gender-biased Tools Shape Newcomer Experiences in OSS Projects
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Previous research has revealed that newcomer women are disproportionately affected by gender-biased barriers in open source software (OSS) projects. However, this research has focused mainly on social/cultural factors, neglecting the software tools and infrastructure. To shed light on...

How Technology Support for Contextualization Affects Enterprise Social Media Use: A Media System Dependency Perspective
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Research background: Using enterprise social media (ESM) in the workplace has become an important channel for initiating communication activities for employees in the organization. However, some organizations reported that they did not obtain expected returns from their ESM...

How Widely Can Prediction Models be Generalized? Performance Prediction in Blended Courses
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Blended courses which mix in-person instruction with online platforms are increasingly common in secondary education. These platforms record a rich amount of data on students' study habits and social interactions. Prior research has shown that these metrics are correlated with...
