Increasing interest has also been witnessed in industry and federal agencies, as evidenced by the recent White House initiative on Big Data. Recently, proliferation of sensors and location sensing devices has created an abundance of geographically referenced data. This workshop will focus on Big Data location analytics. It will renew attention to Big Data and Analytics theories, concepts, and technologies, and how Geographical Information Systems enable visualization and analysis of the location component of Big Data to create additional value to make better decisions. Spatial Big Data tools (SpatialHadoop) that leverage the power and sophistication of traditional Big Data technologies (Apache Hadoop) will be discussed. Big Data opportunities in different industries that are known to leverage geotechnology will be presented. This is part I of a two-part workshop on Big Data and Location Analytics

While extant research has investigated the relationship using an ICT index, there has been no research looking at smartphones, which have been closely associated with the explosive growth in the use of mobile apps and a build-out of large information systems to support their use. To address this gap, this research examines the relationship of ICTs and smartphones with CO2 emissions by employing a country-level data set for the period from 2009 to 2014. Our results show that the relationship of ICTs with CO2 emissions takes an inverted U-shaped curve form, consistent with the EKC hypothesis. Our OLS results also show that CO2 emissions increase with spending on smartphones but decrease as smartphone spending increases further; however, these results are not consistent in fixed effects models. These findings imply that carbon emissions go up with the penetration of ICTs in poorer countries but in wealthier countries ICT penetration and smartphone spending is related to lower CO2 emissions. The results should not be taken as evidence that ICTs cannot lead to greater sustainability in poorer countries, but should be seen as a call for the IS community to help all countries apply existing knowledge and develop new knowledge to use ICTs to reduce emissions in response to the immediate challenge of climate change.

Even though societal interest in digital content has increased along with the growth of an information-oriented society, academic studies of the characteristics, value, flow, and use intensiveness of digital content are still in a nascent stage. Using sample data collected in Korea, this research attempts to evaluate the characteristics of digital content and examine how different components of this content are related to its value, flow, and use intensiveness. We divide content into three broad categories: design characteristics (visual appeal and musicality), scenario characteristics (creativity and entertainment value), and structure (unity and conciseness). Results of our study show significant effects on the value of digital content from all three of these categories. However, the flow (users' immersion in a specific set of content) is influenced only by the musicality of design and the entertainment value. Finally, when users highly rate the value of digital content and report good flow, the use intensiveness of that content tends to increase.

By allowing companies to share their resources, collaborative logistics systems provide companies with an opportunity to create shared value through collaboration, namely, not only enhance the utilization of resources, but also reduce energy consumptions and greenhouse gas emission associated with logistics, production, and transportation. However, the development of collaborative logistics systems is currently at a nascent stage. There are quite a few technological and non-technological barriers to overcome. This research, currently in progress, will highlight one set of social (or non-technological) barriers, that is, competition-oriented conservatism prevalent in the industry, which should be overcome to create shared value. Using the case study methodology and interview data, we attempt to closely investigate ES3 and Flexe, which provide collaborative logistics services and illustrate the requirements for addressing social barriers to create shared value from collaborative logistics systems.

Fabless firms are considered to have an advantage in product innovation, as they can focus their innovation efforts on chip design and can benefit from investments in process innovation made by their manufacturing partners. However, there is little empirical evidence of the performance of fabless firms compared to vertically integrated firms. This research empirically examines the relationship between R&D and the financial performance of fabless and vertically integrated firms from 2000 to 2010. Our results show that fabless firms maintain higher gross and net margins, earn a higher return on assets (ROA) and have greater intangible value (Tobin’s q) than vertically integrated firms when controlling for size, capital intensity and R&D ratio (R&D/sales). This supports the argument that fabless firms achieve greater performance by focusing on one part of the innovation process. The relationship of R&D ratio to net margin is negative for the whole sample, suggesting that the industry may be overinvesting in R&D. Notably, the negative relationship is greater for fabless firms, which spend a higher amount of their sales on R&D. The relationship of R&D ratio to ROA and Tobin’s q is negative, and there is no significant difference between fabless and integrated firms. We conclude that fabless firms outperform integrated firms overall, but are somewhat worse in terms of increasing profits and creating value from their R&D investments.
