Nymi: Identity through heartbeats [Video]

As discussed in #hkuiom over the past years, Identity Management is a major unsolved problem that limits the ability for seamless computing and digitized service delivery. A problem that can provide much profits to the company that solves it. Nymi, which ships this fall, proposes to use an individual’s unique heartbeat, combined with a registered smartphone, as a basis for authentication.

Best Paper Award at Academy of Management Conference

One of my research papers, co-authored with Mariana G. Andrade Rojas, a Ph.D. candidate at The University of Hong Kong, was recognized at the recent Academy of Management Annual Meeting held in Philadelphia, USA. The Academy of Management is the preeminent professional association of management and organizational scholars and its annual meeting draws more than 10,000 students, academics, scholars, and professionals. The paper, titled “Competitive Brokerage: External Resource Endowment and Information Technology as Antecedents” was conferred the Best Student Paper 1st Runner Up Award by the Organizational Communication & Information Systems Division.

AwardHaving a prominent position in a firm’s competition network is a prerequisite for success in the global and embedded environment of the 21st century. In our study, we assert that IT-enabled information management capability, M&A, and strategic centrality act in differing ways to individually and jointly enable firms to obtain such a position. Specifically, we propose the “competitive brokerage” construct to assess firms’ multi-industry competitive positioning and posit that information management capability acts as a substitute for M&A and strategic centrality to attain competitive brokerage. In other words, we posit that an organization’s information technology, acquisitions of other firms and strategic alliances with other organizations endow it with the ability to bridge multiple markets and successfully compete across them with multiple brands.

Analysis of a longitudinal multi-industry competition network supports our assertions. This work offers a novel set of insights to the evolutionary dynamics of network structures literature and the IT business value literature by arguing and empirically demonstrating that in addition to structural elements, firms’ external resource endowment and IT-enabled capabilities influence network positioning.

An abridged version of this paper was accepted for inclusion in the Best Paper Proceedings of the conference (approximately ten percent of all papers are selected as “Best Papers” and accepted for inclusion).

Radical Innovation Strategies [Video]

During our discussions on the value of IT in #hkuiom, I often draw upon examples from my research regarding the role of IT in enabling radical innovation strategies. While the focus of the discussions is not innovation, I use the below mini-lecture video by David Kryscynski, my senior colleague from the Emory Doctoral Program, to provide students a brief overview this topic.

 

Visualizing Your Co-Author Network

I recently decided to create a visualization of my co-author network. I believed that this was a fairly easy task and expected to find a single, very simple tool and instructions for it online. However, much to my chagrin, this process took much longer than I expected. Below are the steps I figured out after some trial and error:

1.   Create a file of your scholarly work using any reference manager. I used EndNote for this task. Then select and export the relevant references into a text file in BibTex format. To accomplish this in EndNote, you must ‘Select Another Style …’ in the citation style drop down, and then select ‘Bib Text Export’. Then click on File->Export and save as a text file with ‘Bib Text Export’ selected as the ‘Output Style’.

 

2. Download, install and run Sci2 from the Indiana University website here. Do the same for Gephi from here.

 

3.  Load the references into Sci2 using the File->Load option. Select the correct format.

 

4. Select the file, click on Data Preparation-> Extract Co-author Network.

 

5. Select the Author Information file and  select Visualization->Networks->Gephi

 

6. Gephi should open up. Create a new undirected graph. You can use the Gephi WYSIWYG editor to edit the graph, add labels, change colors, increase the size of the nodes and edges based on number of authored and co-authored papers respectively.

 

 

 

My output can be seen here. (Note that I used a Yifan Hu layout and only retained first-order connections). This process can be followed to create visualizations for a variety of networks, including a complete co-authorship network, citation networks, networks of Twitter followers, etc.

 

 

 

 

 

The Resource Based View [Video + Slides]

The Business Value of IT is a dominant focus of my research and teaching, and this topic draws heavily from the Resource Based View (RBV). During our discussions on the value of IT in #hkuiom, we often talk about IT resources and capabilities. While the RBV is covered in detail during the Strategic Management courses at the MBA level, it helps to provide the students a brief overview of it as part of the IT resources and capabilities discussion.

I’ve found the below mini-lecture video by David Kryscynski, my senior colleague from the Emory Doctoral Program, to be very helpful in this endeavor.

 

 

In the past, I’ve used these slides (The Resource Based View) to communicate the difference between the ‘5 Forces’ view (something that most audiences are well versed with) and the RBV, along with a brief on how competencies fit into the picture.
